a review of policy analysis purpose and capabilities of electricity system models abstract the aim of this study is to investigate the ability of electricity system models to provide scenario based insights for policy purposes a framework is built from a review of existing studies of model characteristics and their linkages to model scenario types which are linked to the purpose of policy problem analyses the framework can be used as a tool to structure the examination of electricity system models and guide electricity system model selection and enhancement in light of policy problem driven analyses an illustration of the framework is presented by a review of german electricity model scenario studies the review shows that current models are used for the policy purpose of indicator assessment and instrument comparison by quantification of indicators such as monetary or pollution impacts however they are not suitable to provide the means for option reduction problem exploration and political or societal paradigm change exploration as the endogenous model structure for these is missing a particular lack of endogenous treatment was found for renewable technology capacity change and policies learning and productivity growth based technological change socio political technical interactions and limited demonstrated use of uncertainty treatment techniques

germany s dash for coal exploring drivers and factors abstract the german electricity sector has recently seen extensive planning and construction of new coal fired power plants within a period of only a few years new investments amounting to around 15 of the total sector capacity were brought on the way and plans for a multitude of additional projects are pending this dash for coal in germany has raised considerable public concern especially as it risks to undermine recent political attempts to combat global warming yet the question of why the dash for coal has emerged has not yet been addressed in a thorough analysis this article attempts to close this research gap while at the same time contributing as a case study to the general understanding of investment patterns in liberalized electricity markets it finds that the main reasons for the dash have been 1 replacement requirements due to the nuclear phase out 2 the onset of a new investment cycle in the power market 3 favorable economic and technological prospects for coal compared with natural gas in the long run 4 a status quo bias of investors in regard to future renewable deployment 5 explicit political support for coal and 6 the ineffectiveness of public protest in hampering new projects

the environmental social interface of sustainable development capabilities social capital institutions the social dimension has commonly been recognised as the weakest pillar of sustainable development notably when it comes to its analytical and theoretical underpinnings while increasing attention has lately been paid to social sustainability the interaction between the environmental and the social still remains a largely uncharted terrain nevertheless one can argue that the key challenges of sustainable development reside at the interfaces synergies and trade offs between its various dimensions this paper looks for preliminary ideas on frameworks for analysing the environmental social interface it first discusses the concept of sustainable development and the relations of the three dimensions of sustainability on the basis of the fundamental premises of neoinstitutional and ecological economics and briefly presents the bioeconomy model based on this conceptualisation of sustainable development it then goes on to analyse two popular ways of addressing the social dimension of sustainability namely the capability approach of amartya sen and the concept of social capital and discusses the potential of these as bases for the analysis of the environment social interaction the organisation for economic cooperation and development oecd environmental performance review epr programme is presented as an example of attempts to analyse the environmental social interface in practice the paper concludes by noting that a single framework for studying environmental social interface is neither feasible nor desirable it questions the usefulness of analysing only two dimensions of sustainability at a time and emphasises the need to situate the analysis in its context in particular it stresses the need to involve the potential users as well as to take into account the planned use of the analysis and the interactions between different levels of analysis and decision making capabilities and social capital can both be useful in structuring thoughts but are not as such directly applicable as suitable analytical frameworks in particular they do not provide adequate tools for examining the social preconditions for institutional change needed for environmentally sustainable development

values in the smart grid the co evolving political economy of smart distribution investing in smart grid infrastructure is a key enabler for the transition to low carbon energy systems recent work has characterised the costs and benefits of individual smart investments the political economy of the uk electricity system however has co evolved such that there is a mismatch between where benefits accrue and where costs are incurred leading to a problem of value capture and redeployment further some benefits of smart grids are less easy to price directly and can be classified as public goods such as energy security and decarbonisation this paper builds on systemic treatments of energy system transitions to characterise the co evolution of value capture and structural incentives in the electricity distribution system drawing on semi structured interviews and focus groups undertaken with smart grid stakeholders in the uk this leads to an identification of municipal scale values that may be important for business models for the delivery of smart infrastructure municipalities may thus pursue specific economic opportunities through smart grid investment this supports recent practical interest in an expanded role for municipalities as partners and investors in smart grid infrastructures 2014 the authors published by elsevier ltd this is an open access article under the cc by license

public prioritisation of energy affordability in the uk much research has focused on the so called energy trilemma i e three leading energy policy issues energy security affordability and climate change mitigation whilst substantial understanding exists of why people support climate friendly energy policies little is known about why they think affordability is important particularly what leads members of the public to identify this policy goal as more important than other objectives here we examine this question via a nationally representative survey of 2441 uk residents and demonstrate that concerns about personal costs explain a small amount of variation in the prioritisation of affordability as an energy policy goal a range of other factors also significantly contribute one such factor is beliefs about who is responsible for energy transitions these findings suggest policy actions to address affordability concerns should go beyond energy prices and include additional considerations such as distributive justice and equality

the co evolutionary relationship between energy service companies and the uk energy system implications for a low carbon transition abstract the energy service company esco business model is designed to reward businesses by satisfying consumers energy needs at less cost and with fewer carbon emissions via energy demand management and or sustainable supply measures in contrast the revenue of the incumbent energy utility company euco model is coupled with the sale of units of energy which are predominantly sourced from fossil fuels the latter is currently dominant in the uk this paper addresses two questions first why has the esco model traditionally been confined to niche applications second what role is the esco model likely to play in the transition to a low carbon uk energy system to answer these the paper examines the core characteristics of the esco model relative to the euco model the paper then examines how escos have co evolved with the various dimensions of the energy system i e ecosystems institutions user practices technologies and business models to provide insight into how escos might help to shape the future uk energy system we suggest that institutional and technological changes within the uk energy system could result in a more favourable selection environment for escos consequently enabling the esco model to proliferate at the expense of the euco model

towards improved policy processes for promoting innovation in renewable electricity technologies in the uk this paper analyses recent current and potential future relations between policy processes and substantive outcomes in uk low carbon innovation policy focussing on policies relating to renewable electricity generation technologies it examines the development of policy processes relating to the adoption and implementation of the renewables obligation and how these may affect the current and likely future success of the obligation in promoting low carbon innovation it examines the new policy and institutional processes put in place in the 2003 energy white paper and argues that these are unlikely to provide the strategic long term framework needed to realise the ambitious goals for uk energy policy set out in the white paper finally it outlines some suggestions for further development of policy processes to facilitate improved delivery of these goals based on guiding principles for sustainable innovation policy processes developed by the authors and their colleagues

a coevolutionary framework for analysing a transition to a sustainable low carbon economy this paper proposes a coevolutionary framework for analysing a transition to a sustainable low carbon economy based on the coevolution of ecosystems technologies institutions business strategies and user practices within a multi level micro meso macro perspective this builds on and develops previous coevolutionary analyses of long term technological and industrial change and recent renewed interest within ecological economics on coevolutionary approaches previous work has analysed how the coevolution of technologies and institutions has led to the lock in of current high carbon energy systems and how the coevolution of physical and social technologies and business strategies has brought significant material and welfare benefits to the minority of the world s population living in industrialised countries the coevolutionary framework proposed here may be used to undertake 1 detailed empirical analyses at a micro meso level of the challenges relating to the innovation and adoption of particularly low carbon technologies 2 as a framework for analysing the multi level interaction of social and technological elements within potential transition pathways to a low carbon energy system 3 to assess the implications for economic growth and prosperity of a transition to a low carbon economy and 4 to assist in the development of more formal multi level evolutionary economic models

delivering a secure electricity supply on a low carbon pathway abstract the energy system can only be considered sustainable in the long term if it is low carbon affordable and secure these three create a complex trilemma for all stakeholders in the energy business who have to strike a careful balance without neglecting any one aspect this discussion paper examines the issues surrounding security of supply of the power system which has received less attention than the other aspects it looks at how threats and mitigation measures can be classified in terms of where they act on the supply chain and the timescale over which they act only by considering the full range of timescales from seconds to decades can the full picture emerge of the effects of new technologies on security of supply an examination of blackouts over the past 40 years sheds light on the causes of failure to supply and the most vulnerable aspects of the supply chain

a comparative analysis of the costs of onshore wind energy is there a case for community specific policy support abstract there is growing policy interest in increasing the share of community owned renewable energy generation this study explores why and how the costs of community owned projects differ from commercially owned projects by examining the case of onshore wind in the uk based on cross sectoral literature on the challenges of community ownership cost differences are attributed to six facets of an organisation or project internal processes internal knowledge and skills perceived local legitimacy of the project perceived external legitimacy of the organisation investor motivation and expectations and finally project scale these facets impact not only development costs but also project development times and the probability that projects pass certain critical stages in the development process using survey based and secondary cost data on community and commercial projects in the uk a model is developed to show the overall impact of cost time and risk differences on the value of a hypothetical 500 kw onshore wind project the results show that the main factors accounting for differences are higher pre planning costs and additional risks born by community projects and suggest that policy interventions may be required to place community owned projects on a level playing field with commercial projects

the enactment of socio technical transition pathways a reformulated typology and a comparative multi level analysis of the german and uk low carbon electricity transitions 1990 2014 abstract this paper aims to make two contributions to the sustainability transitions literature in particular the geels and schot 2007 res policy 36 3 399 transition pathways typology first it reformulates and differentiates the typology through the lens of endogenous enactment identifying the main patterns for actors formal institutions and technologies second it suggests that transitions may shift between pathways depending on struggles over technology deployment and institutions both contributions are demonstrated with a comparative analysis of unfolding low carbon electricity transitions in germany and the uk between 1990 2014 the analysis shows that germany is on a substitution pathway enacted by new entrants deploying small scale renewable electricity technologies rets while the uk is on a transformation pathway enacted by incumbent actors deploying large scale rets further analysis shows that the german transition has recently shifted from a stretch and transform substitution pathway to a fit and conform pathway because of a fightback from utilities and altered institutions it also shows that the uk transition moved from moderate to substantial incumbent reorientation as government policies became stronger recent policy changes however substantially downscaled uk renewables support which is likely to shift the transition back to weaker reorientation

barriers to green supply chain management in indian mining industries a graph theoretic approach a country s mining industry despite its significant contributions to the country s economic growth generally has a very poor public image because it is considered as a major environmental polluter to acquire an improved social image as well as to comply with government regulations mining industries are increasingly implementing environmental management systems ems cleaner production cp and adopting green supply chain management gscm practices gscm focuses on a reduction of the adverse impacts of supply chain activities as well as a minimization of energy and material usage this study focuses on the mining industry as a case study by which we will identify factors and sub factors hindering gscm implementation a graph theoretic and matrix approach gtma has been used to quantify the adverse impact of these barriers on gscm implementation an assessment of the inhibiting strength of the barriers will help decision makers rank them and decide a course of action that will make an optimum utilization of available resources during times of resource scarcity

the governance of sustainable socio technical transitions a quasi evolutionary model of socio technical transitions is described in which regimes face selection pressures continuously differentiated transition contexts determine the form and direction of regime change in response to these pressures the articulation of pressures and the degree to which responses are coordinated and based on resources available within the regime define the transition context four alternative contexts are described endogenous renewal re orientation of trajectories emergent transformation and purposive transitions agency and power in the governance of regime transformation are analysed power to affect change depends on regime membership the distribution of resources for change and expectations

shale gas policy in the united kingdom an argumentative discourse analysis shale gas has become an energy policy priority in the united kingdom in light of profitable extraction activities in the united states since 2012 the coalition government has created key economic drivers to encourage shale exploration whilst growing activism in affected site communities has stirred significant media and academic commentary this study examines the growing national debate as a matter of discourse adopting an argumentative discourse analytic approach to assess data collected from stakeholder interviews n 21 and key policy actor statements quoted in broadsheet newspapers we explore three dominant storylines emerging in relation to shale gas policy 1 cleanliness and dirt concerns the relative framing of the environmental benefits and harms of shale gas 2 energy transitions pathways and diversions concerns geographic metaphors of transitions to carbon intensive and low carbon energy systems and 3 geographies of environmental justice concerns divisions of economic benefit distribution environmental impact and procedural fairness we find that central government policy rhetoric emphasises economic development regulatory oversight and distribution of benefits to site communities whilst minimising discussion of the implications of shale gas for anthropogenic climate change the role of these discourses in influencing shale gas policy is discussed

supply chain specific understanding the patchy success of ethical sourcing initiatives as a number of high profile companies have found to their cost corporate reputations can be significantly affected by firms management of sustainability issue including those that are outside their direct control such as the environmental and social impacts of their supply networks this paper begins by examining the relationship between corporate social responsibility reputation and supply network conditions it then looks at the effectiveness of one tool for managing supply network sustainability issues ethical sourcing codes of conduct by examining how the characteristics of three supply networks branded clothes diy wood products and branded confectionary affects the implementation ethical sourcing codes of conduct it ends by setting out conclusions on why implementation of such codes has been so much more successful in some sectors than others and recommendations on effective approaches to managing sustainability issues in supply networks

earning trajectories of highly educated immigrants does place of education matter the author compares the earnings and earning trajectories of u s college educated immigrants with those of similar immigrants who completed their education abroad using cross sectional and longitudinal data from the 1993 and 2003 national surveys of college graduates adjusting for demographics results based on cross sectional data suggest that the annual earnings of college educated foreign born men were 9 less than those of similar u s born men whereas the annual earnings of college educated foreign born women were 3 less than those of similar u s born women after further adjusting for place of education however the gap narrowed by 42 for men and vanished for women an analysis of longitudinal data reveals that in the first 15 years after arrival u s educated foreign born science and engineering s e professionals had higher earnings growth relative to native born s e professionals than their foreign educated counterparts evidence also indicates that attrition was associated with labor

transition pathways for a uk low carbon electricity system comparing scenarios and technology implications the united kingdom uk has placed itself on a transition towards a low carbon economy and society through the imposition of a goal of reducing its greenhouse gas emissions by 80 by 2050 a set of three low carbon transition pathways were developed to examine the influence of different governance arrangements on achieving a low carbon future they focus on the power sector including the potential for increasing use of low carbon electricity for heating and transport these transition pathways were developed by starting from narrative storylines regarding different governance framings drawing on interviews and workshops with stakeholders and analysis of historical analogies here the quantified pathways are compared and contrasted with the main scenarios developed in the uk government s 2011 carbon plan this can aid an informed debate on the technical feasibility and social acceptability of realising transition pathways for decarbonising the uk energy sector by 2050 the contribution of these pathways to meeting britain s energy and carbon reduction goals are therefore evaluated on a whole systems basis including the implications of upstream emissions arising from the fuel supply chain ahead of power generators themselves

emergence of new economics energy transition models a review abstract well known academic and non academic institutions call for a new approach in economics able to capture features of modern economies including but not limited to complexity non equilibrium and uncertainty in this paper we provide a systematic review of ecological macroeconomic models that are suitable for the investigation of low carbon energy transitions and assess them based on the features considered desirable for a new approach in economics we draw two main conclusions firstly the knowledge base and structure of these existing ecological macroeconomic models are relevant alongside other types of models for the creation of a new approach in economics secondly the reviewed models are policy relevant especially in the context of the complexity and urgency of rapid energy transitions where increasingly policymakers require economic models able to capture real world characteristics however further improvements are needed to these models and future research should focus on i assuring comparability of models results and their policy insights ii incorporation of the relationships between macroeconomics finance and sustainability and iii the institutionalization of a new approach in economics

what lessons have been learned in reforming the renewables obligation an analysis of internal and external failures in uk renewable energy policy abstract despite operating a delivery programme for res e since 1990 uk targets and policy goals have not been achieved in response the government reformed the ro this article re examines uk renewable energy policy by analysing the internal and external failures of the various mechanisms to determine if government has learnt from previous experience in reforming the ro government did not learn from their own actions during the nffo ro transition evidenced by high levels of similarity in internal external failures the reformed ro is expected to significantly increase deployment has provided a renewables package by comprehensively addressing both internal external failures but major internal failures price financial risk still remain resulting in contiguous failures over two decades and two mechanism changes nffo ro ro reformed ro success will again be heavily dependent on a select few technologies and new untested measures to combat external failures mechanism extension to 2037 is probably the single most important factor underlying potential deployment increases however introducing a fit like system via the sheer number of bolt on reforms to counter policy failures indicates loss of direction and clarity overall although government appears to have learnt some of its lessons from the past two decades significant doubt remains whether renewable energy policy objectives will be met via the latest mechanism change

governing transitions cases and insights from two periods in the history of the uk gas industry the paper aims to inform historically the analyses of future sociotechnical transition pathways in the electricity sector particularly those developed by the transition pathways to a low carbon economy project it also aims to inform the theoretical approach to transitions by focusing on key decisions at branching points that led to transitions in the uk gas energy services regime which occurred under different governance patterns the first historical case study covers the market led transformation of the manufactured gas regime from 1877 to 1914 which developed the end uses of gas beyond lighting to include cooking and extended access to working class consumers the second case study covers the period from 1948 to 1977 historically reconstructing the transition from town gas to natural gas this state led and coordinated conversion to natural gas was preceded by a period of destabilisation of the manufactured gas regime the co existence of several niche technologies and the hybridisation of the key actors and technological infrastructures of the incumbent regime comparing the cases provides insights for future energy service transitions by addressing the significance of power trust and networking in the decision making processes involved in the governance of energy transitions

immigrant earnings age at immigration matters a correlation between age at immigration and earnings is observed in canadian census data the evidence supports three underlying sources of the effect first work expe rience in the source country yields virtually no return in the host country second the return to education varies with age at immigration and finally an acculturation effect is observed for immigrants who are visible minorities or whose mother tongue is not english further it is found that educational attainment and relatedly earnings vary systematically across age at immigration with those arriving around age 15 to 18 obtaining fewer years of education

a degrowth transition pathways for the degrowth niche to replace the capitalist growth regime abstract facing the intertwined environmental social and economic crisis requires us to seriously consider alternatives to the current capitalist system including the emerging concept of degrowth existing understandings of degrowth have focused on characterizing the shape the key elements and the proposals for a degrowth society however its dynamic and evolving nature as an alternative vision of the future and the dynamics of a transition toward degrowth are inadequately considered this paper seeks to address this conceptual gap through a reconceptualisation of degrowth as a radical niche innovation to the capitalist growth regime by extending the multi level perspective framework to the capitalist growth system we undertake a critical reconsideration of the multi level perspective exposing key assumptions of this framework grounded in capitalist economic theory through this we propose a pluriversal potential pathway for change to consider this further a bibliometric analysis is used to measure and visualize research activity in degrowth as a proxy for the processes of development of the degrowth niche then we return to the multi level perspective to consider two potential pathways for change involving the degrowth niche and the capitalist growth regime finally we point to areas for further research that build on this new conceptualisation of a degrowth transition

taking stock of the local impacts of community owned renewable energy a review and research agenda abstract a growing literature suggests that community owned renewable energy cre projects have the potential to deliver a range of environmental and local socio economic benefits there is relatively little empirical evidence to substantiate this with few systematic efforts to assess social and environmental impacts or to understand the context in which given impacts arise in this paper we review and conceptualise the local impacts commonly cited in the literature and dissect the empirical evidence currently available to support their occurrence having assessed the quality of evidence and pinpointed knowledge gaps we draw on methodological literature to identify approaches necessary to improve our understanding of the local impacts of cre and explore their patterns of occurrence we find a lack of robust survey and statistical evidence across all the seven impact categories identified of the impacts identified empowerment and access to affordable energy are found to be the least studied in addition several impacts are associated only with specific types of community energy projects we argue that the paucity of consistent evidence for direct impacts associated with the development processes and direct outcomes of projects suggests that the most substantial local impacts result from medium to long term indirect project outcomes and the investment of project revenues in the local community as such collective funding pools and negotiation processes around their distribution towards private versus public goods play a crucial role in determining transformative local impacts of cre

a dual narrative modelling approach for evaluating socio technical transitions in electricity sectors the sustainability transition of electricity sectors is a matter of competition between multiple emerging renewable systems and dominant established conventional systems these transitions are multi dimensional and are featured with non linear and causal interactions between social technical economic and political components understanding the dynamic of transitions i e how transitions unfold can inform effective policy interventions this paper aims to present a narrative modelling approach to improve the understanding and description of transition dynamics in electricity sectors the central ideas of the paper are 1 the use of qualitative transition narratives helps to capture the co evolving nature of society and technology which are simplified in modelling approaches 2 narratives with concepts from the sustainability transitions field also guide the development of a model structure and 3 computational models in return reproduce the complexity of transition dynamics i e feedback loops non linearity and time delays the features which are impracticable to analyse with transition narratives alone we use the historical transition of india s electricity sector to demonstrate the implementation of our proposed approach first an overview of the transition narratives is presented and the model structure developed based on the narratives is explained then it is argued how the coupling of the narratives and model improves our understating of the positive impacts as well as the side effects of stable feed in tariffs and accelerated depreciation on the penetration levels of wind and solar electricity

the winds of change how wind firms assess germany s energy transition abstract in september 2010 the german government initiated a plan to shift from fossil fuels to renewable energies with nuclear power as a bridging fuel following the fukushima nuclear disaster however the government decided to immediately shut down almost half of germany s reactors and phase out the rest by 2022 the outcome of germany s energy transition energiewende from high carbon and nuclear sources of power to renewable energies has implications for germany s prosperity and may serve as either a positive or negative model for other countries achieving the energiewende will require the commitment of germany s renewable energy companies whose opinions on the transition have not yet been reported this article seeks to help fill this gap by relating the views of over 80 percent of germany s wind industry per market share the firms in our study are mostly optimistic about the government s ambitious targets but express concern over the prospects for offshore wind lagging network expansion and the efficacy of extant legislation to support the transition from the government s side cost concerns have already led to discussions of slowing the transition leading to a push pullback policy approach for the transition to proceed smoothly fundamental issues such as market design must be resolved

comparison of technology efficiency for co2 emissions reduction among european countries based on dea with decomposed factors abstract for consistent and effective co 2 reduction many countries need to improve not only the technical efficiency of co 2 mitigation but also environmental responsibility in this study we examine both the technical efficiency and voluntary environmental consciousness vec of 12 european countries using a two stage data envelopment analysis dea in the first stage we measured the technical efficiency of green energy technologies get associated with fossil fuels renewable energy and storage technologies of each country for energy generation with regard to co 2 emissions by surveying get related patents using the logarithmic mean divisia index lmdi we decomposed co 2 emissions into the following technological factors energy intensity fuel mix and co 2 emission coefficient in the second stage we quantified the vec in each country by investigating get patent changes via research and development r d investment at given changes in co 2 emissions the results show different aspects for each country in terms of technical efficiency and vec suggesting potential levels of both efficient co 2 reductions and desirable get development by using reference countries as a benchmark our study methodology and results can contribute to establishing effective national technology policy and aid in calls for common responsibility and the active participation of nations in addressing climate change

covariance versus component based estimations of performance in green supply chain management abstract in this paper we investigate the relationships between environmental management em and performance to verify whether the implementation of an effective internal environmental is a firm s precondition to belong to a green supply chain which type of environmental practices either internal or external contribute the most to increasing a firm s performances and whether performing the environment translates into higher economic performance we use structural equation modeling for testing our research hypotheses on a large sample of italian firms and estimate the structural paths between constructs by means of both covariance and component based approaches the use of both estimation methods allows us contributing to the recent debate about the specification of the performance construct as an emerging rather than as a latent variable and then using formative rather than reflective indicators formative indicators are used whenever a construct does not exist without its measures any change in one of the indicators causes a change in the construct and the measures are ingredients of the construct rather than being caused by it for instance economic performance is an emerging construct since economic measures e g profits and market share contribute to forming the construct rather than reflecting the behavior of the latent variable we show that the correct model specification changes the estimates of the path coefficients and leads to research findings aligned to the literature our results indicate that being green internally is a prerequisite for collaboration into a green supply chain internal em contributes to increasing performance more than external em while performing the environment does not lead to a higher economic performance

do corporate global environmental standards create or destroy market value arguments can be made on both sides of the question of whether a stringent global corporate environmental standard represents a competitive asset or liability for multinational enterprises mnes investing in emerging and developing markets analyzing the global environmental standards of a sample of u s based mnes in relation to their stock market performance we find that firms adopting a single stringent global environmental standard have much higher market values as measured by tobin sq than firms defaulting to less stringent or poorly enforced host country standards thus developing countries that use lax environmental regulations to attract foreign direct investment may end up attracting poorer quality and perhaps less competitive firms our results also suggest that externalities are incorporated to a significant extent in firm valuation we discuss plausible reasons for this observation

transition pathways revisited established firms as multi level actors in the heavy vehicle industry abstract the multi level perspective on sustainability transitions positions established firms incumbents as defenders of existing technologies at the regime level by contrast it positions new entrants at the niche level as promoters of new technologies this paper challenges the positioning of firms as actors on either regime or niche levels based on a comparative analysis of technology strategies in the heavy vehicle industry the paper shows that established firms are active at both levels developing several technology alternatives simultaneously this means that incumbents technology strategies determine important parts of the required niche regime interactions the paper also shows how incumbents may pursue contrasting technology strategies while some adopt a dualistic approach keeping regime and niche level activities technologically and commercially separate others develop integrated strategies where niche activities are leveraged to impact upon the regime level the cases studied illustrate how the success of such integrated strategies depends on the emergence of bridging policies bridging policies are relevant both for linking early niche markets to broader regime level markets and for supporting further technological advancements of niche markets

socio technical analysis of the electricity sector of mexico its historical evolution and implications for a transition towards low carbon development abstract the electricity sector of mexico has been found itself in continuous transitions since its beginning in the 19th century however the historical reform to the sector that recently took place together with new energy market configurations around the globe may pose an important challenge to transitioning towards a low carbon sector the work presented here was aimed at understanding in a qualitative manner the complex interactions between the main social technical and environmental aspects that have guided the sector in the past their influence on the current structure and its future development through the application of the multi level perspective mlp with a governance and agency perspective additionally the work tried to elucidate the implications of the incumbent position of the natural gas industry and the possibilities for low carbon technologies the conclusions remark the importance of previous sector configurations in the present structure the important role of government in promoting low carbon technologies together with investment by market actors and the possible window of opportunity that the natural gas industry in mexico may provide to low carbon energy technologies

evolving theories of sustainability and firms history future directions and implications for renewable energy research abstract sustainability has become a critical perspective in managing firms via a holistic approach by considering economic environmental and social dimensions of firms with the rising significance of sustainable development the theories of sustainability in firms have evolved during the past six decades this article offers a critical review of the evolving theories linking sustainability to firms and discusses their implications for future renewable energy research the relationships among different theories are critically analysed and the directions for future research are discussed the paper shows that the main theories linking sustainability to firms in a chronological order are 1 corporate social responsibility 2 stakeholder theory 3 corporate sustainability and 4 green economics currently various innovative approaches and new theories emerged such as co evolution theory and multi level perspective reflecting three directions of theory development namely 1 shifting from what to how 2 growing use of interdisciplinary approach and 3 towards broader systems renewable energy studies associated with firms and future research opportunities in this area are also critically analysed the comprehensive review offered in this paper provides a useful reference for policy makers corporate managers and researchers interested in corporate sustainability and renewable energy related studies

the impact of host country schooling on earnings a study of male immigrants in the united states immigrants in the united states who acquire u s schooling earn higher wages than other immigrants using data from the u s censuses and the national longitudinal survey of youth we show that this wage advantage results from both greater educational attainment and higher returns to education the higher returns are not the consequence of ability bias or greater english proficiency of those who acquire u s schooling returns to years of non u s education are higher for immigrants who complete their schooling in the united states consistent with the view that u s schooling upgrades or certifies education received in the source country for those without u s schooling returns are higher for immigrants from highly developed countries and countries for which english is an official language

simulating the new british electricity market reform abstract the british government is implementing fully its novel electricity market reform gb emr its objective in line with european directives aims at replacing existing nuclear and coal plant with low carbon systems to deliver reliable and affordable power though the gb emr has proposed several policy instruments for meeting its objectives and the academic literature has discussed the main issues no known report includes a comprehensive and dynamic simulation exercise that assesses the extent of this profound and important initiative this paper presents a system dynamics model that supports analysis of long term effects of the various policy instruments that have been proposed in the gb emr focusing on environmental quality security of supply and economic sustainability using lessons learned from simulation the paper concludes that effectively achieving the gb emr objectives requires this comprehensive intervention or a similar one that includes the promotion of low carbon electricity generation through the simultaneous implementation of various direct and indirect incentives such as a carbon price floor a feed in tariff fit and a capacity mechanism

niche accumulation and hybridisation strategies in transition processes towards a sustainable energy system an assessment of differences and pitfalls this paper assesses two patterns in transition processes for using them as strategies towards a sustainable energy system i e niche accumulation and hybridisation both play important but different roles in transitions the expected success of these strategies depends on the innovation s history and the innovation context the different strategies are illustrated with several examples from the energy domain

empirical age earnings profiles the human capital earnings function in which earnings are expressed as a quadratic in potential experience is probably the most widely accepted empirical specification in economics in spite of its widespread acceptance the human capital earnings function provides a very poor approximation of the true empirical relationship between earnings and experience the standard formulation understates early career earnings growth by about 30 50 and overstates midcareer growth by 20 50 however simple alternative specifications that fit the data are available

assimilation changes in cohort quality and the earnings of immigrants this paper reexamines the empirical basis for two facts that seem to be found in most cross section studies of immigrant earnings 1 the earnings of immigrants grow rapidly as they assimilate into the united states and 2 this rapid growth leads to many immigrants overtaking the earnings of the natives within 10 15 years after immigration using the 1970 and 1980 u s censuses this paper studies the earnings growth experienced by specific immigrant cohorts during the period 1970 80 it is found that within cohort growth is significantly smaller than the growth predicted by cross section regressions for most immigrant groups this differential is consistent with the hypothesis that there has been a secular decline in the quality of immigrants admitted to the united states

immigrant earnings assimilation estimates from longitudinal data analysis of longitudinal data for immigrants presents a more pessimistic portrait of immigrants economic success first the rate of growth of immigrant earnings was overstated in census based studies second the worsening of immigrant earnings for more recent arrival cohorts is deeper than previously suggested against these two negative findings one must keep in mind an important caveat the steeper cohort decline in earnings may be a sign of greater human capital investment by more recent immigrants longitudinal data suggest a strong degree of earnings convergence immigrants who start at lower earnings quickly make up a large part of the deficit relative to their immigrant counterparts

immigrant and emigrant earnings a longitudinal study this paper analyzes the relationship between earnings and the extent of assimilation cohort quality change and return migration experienced by the foreign born population the study uses the longitudinal data available in the survey of natural and social scientists and engineers the analysis reveals that there was a sizable decline in the skills of this population over the last two decades in addition the study shows that return migration is more likely among immigrants who did not perform well in the u s labor market

assessing long term energy security the case of electricity in the united kingdom there is a growing body of research into the potential security risks and trade offs which may emerge over the long term development of energy systems as part of this body of research this paper aims to develop and demonstrate a set of indicators for assessing the security of long term national electricity scenarios this paper extends the empirical work of existing frameworks by including reliability and cost parameters alongside a range of other important aspects of energy security such as diversity trade and acceptability and by using both qualitative and quantitative indicators without aggregation in order to identify trade offs this paper uses the indicators to assess the energy security implications of three plausible long term scenarios for the uk electricity system the results indicate that a major risk may be experienced by a lack of flexible responsive supply capacity in low carbon electricity pathways reducing overall energy demand is found to be the most beneficial policy for improving energy security in terms of generating benefits in multiple dimensions the paper finds that energy security is often conceptualised as the avoidance of causes of insecurity such as insecure fuel imports but that an equally important aspect of security lies in maximising responses to insecurity for example by increasing the flexibility and responsiveness of both supply and demand

removing environmental market failure through support mechanisms insights from green start ups in the british french and german energy sectors environmentally relevant market failure related to the lack of value attached to environmentally beneficial economic activity constrains environmental entrepreneurship as reported by dean and mcmullen journal of business venturing 22 50 76 2007 unless this market failure is addressed green start ups will be confined to a green prison as stated in pacheco et al sustainable development and entrepreneurship 25 464 480 2010 unable to grow and disseminate their eco innovations out with environmental niche markets in britain france and germany support mechanisms promote the expansion of renewable power technologies this paper examines environmental entrepreneurs perceptions of the importance and effectiveness of support mechanisms in removing environmental market failure in the energy sectors of these three countries our findings suggest that these support mechanisms are perceived by entrepreneurs as having provided a crucial pecuniary motivation among consumers to adopt eco innovation creating greater market certainty for green start ups however when these support mechanisms are reformed aiming at greater market integration for eco innovation green start ups find this transition from protection to more market exposure as challenging and more suited for incumbent firms

you can t take it with you immigrant assimilation and the portability of human capital the national origin of an individual s human capital is a crucial determinant of its value education and labor market experience acquired abroad are significantly less valued than human capital obtained domestically this difference can fully explain the earnings disadvantage of immigrants relative to comparable natives in israel variation in the return to foreign schooling across origin countries may reflect differences in its quality and compatibility with the host labor market the return to foreign experience is generally insignificant acquiring additional education following immigration appears to confer a compound benefit by raising the return to education acquired abroad

the german energy transition as a regime shift abstract in this paper i use the resilience framework to interpret the project of transforming the german energy system into a renewable energy sources res based system the so called energiewende as a regime shift this regime shift comprises several transformations which are currently altering the technological political and economic system structure to build my argument i first sketch how technological political and economic developments reduced the resilience of the conventional fossil nuclear energy regime and created a new res regime second i depict recent changes in german public discourse and energy policy as the shift to the res regime third i highlight the challenges involved with increasing the resilience of the res regime in particular sufficient resilience of the electricity transmission grid appears to be crucial for facilitating the transformation of the whole energy system

a low carbon industrial revolution insights and challenges from past technological and economic transformations recent efforts to promote a transition to a low carbon economy have been influenced by suggestions that a low carbon transition offers challenges and might yield economic benefits comparable to those of the previous industrial revolutions this paper examines these arguments and the challenges facing a low carbon transition by drawing on recent thinking on the technological economic and institutional factors that enabled and sustained the first british industrial revolution and the role of general purpose technologies in stimulating and sustaining this and subsequent industrial transformation processes that have contributed to significant macroeconomic gains these revolutions involved profound long drawn out changes in economy technology and society and although their energy transitions led to long run economic benefits they took many decades to develop to reap significant long run economic benefits from a low carbon transition sooner rather than later would require systemic efforts and incentives for low carbon innovation and substitution of high carbon technologies we conclude that while achieving a low carbon transition may require societal changes on a scale comparable with those of previous industrial revolutions this transition does not yet resemble previous industrial revolutions a successful low carbon transition would however amount to a different kind of industrial revolution

business model innovation in electricity supply markets the role of complex value in the united kingdom this research investigates the new opportunities that business model innovations are creating in electricity supply markets at the sub national scale these local supply business models can offer significant benefits to the electricity system but also generate economic social and environmental values that are not well accounted for in current policy or regulation this paper uses the uk electricity supply market to investigate new business models which rely on more complex value propositions than the incumbent utility model nine archetypal local supply business models are identified and their value propositions value capture methods and barriers to market entry are analysed this analysis defines complex value as a key concept in understanding business model innovation in the energy sector the process of complex value identification poses a challenge to energy researchers commercial firms and policymakers in liberalised markets to investigate the opportunities for system efficiency and diverse outcomes that new supplier business models can offer to the electricity system

learning from experience the development of the renewables obligation in england and wales 2002 2010 abstract the uk has enviable renewable resources both onshore wind and offshore wind wave and tidal the offshore valuation group 2010 the government has had policy mechanisms in place since 1990 to encourage these resources to be developed the current mechanism the renewables obligation ro was specifically designed to emphasise competition and therefore to fit in with the uk s overall strategic approach to energy policy however as yet it has not delivered the capacity that it was designed to do and as a result the uk faces a difficult challenge in attempting to meet european wide renewable energy targets for 2020 as well as longer term decarbonisation targets this paper explores some of the major reasons why the ro has performed so poorly to date and considers the prospects for improvement up to 2020 it concludes that the strategic emphasis on competition in the support mechanisms has played a key role in limiting renewables development but that the mechanism has changed significantly since it was introduced however these changes together with proposals for electricity market reform still do not address important elements of risk in comparison with a standard feed in tariff

the hygienic transition from cesspools to sewer systems 1840 1930 the dynamics of regime transformation this article addresses the topic of transition and system change and proposes endogenous regime transformation as alternative transition path to technological substitution using sociological and institutional insights the dynamics of regime transformation are conceptualised two characteristics are pressure from outsider groups and adjustments in cognitions norms and formal rules enacted by regime insiders the transformation perspective is illustrated with a historical case study the hygienic transition from cesspools to integrated sewer systems in the netherlands the case study is used to make additions to the transformation perspective particularly with regard to tactical and strategic games

the economics of immigration this literature review concerns the impact of immigration on the economy of the host country focusing on the experience of the united states the emphasis is on the period from the 1970s to the 1990s the author shows that research earlier in this period generally concluded that the economic effects of immigration were positive but that more recent research on later migrations have generally concluded that immigration may be having an adverse effect on the earnings of native unskilled workers and be placing an increased burden on welfare programs the importance of such economic analysis for the formulation of appropriate migration policies is stressed

deep transitions emergence acceleration stabilization and directionality abstract industrial society has not only led to high levels of wealth and welfare in the western world but also to increasing global ecological degradation and social inequality the socio technical systems that underlay contemporary societies have substantially contributed to these outcomes this paper proposes that these socio technical systems are an expression of a limited number of meta rules that for the past 250 years have driven innovation and hence system evolution in a particular direction thereby constituting the first deep transition meeting the cumulative social and ecological consequences of the overall direction of the first deep transition would require a radical change not only in socio technical systems but also in the meta rules driving their evolution the second deep transition this paper develops a new theoretical framework that aims to explain the emergence acceleration stabilization and directionality of deep transitions it does so through the synthesis of two literatures that have attempted to explain large scale and long term socio technical change the multi level perspective mlp on socio technical transitions and techno economic paradigm tep framework

to identify the critical success factors of sustainable supply chain management practices in the context of oil and gas industries ism approach abstract the concept of sustainable supply chain management sscm has been considered as an important organizational philosophy to achieve profits by reducing environmental risk and impact while improving the economic and social efficiency factors esef the objective of this paper is to present an approach to identify the critical success factors csfs of motivation and encouragement for the successful implementation of sscm practices in indian oil and gas industries 32 csfs were identified from the literature and opinions of academicians and industry practitioners the interpretive structural modeling ism methodology was used for establishing the mutual relationships among the drivers which not only helps in understanding the relative relationship between the csfs but also in determining their interdependence while implementing sustainability further the importance of csfs with respect to sustainability was identified based on their driving and dependence power by using micmac analysis global climatic pressure and ecological scarcity of resources was determined to be the most influential criterion that may force industries to implement sustainable practices an example of indian oil and gas industry has been presented to show the real world applicability of the proposed model this study may help academicians government regulators and practitioners to emphasize their efforts towards implementation of sscm at various levels of organization

new evidence on the economic progress of foreign born men in the 1970s and 1980s this study examines the economic progress of foreign born men in the united states europeans entered the united states with relatively high wages and earned wages comparable to natives over their life course japanese korean and chinese men entered with lower wages but quickly caught up with u s born workers mexicans and central americans entered with low wages and the wage gap between themselves and u s born workers has not shrunk disparities in completed years of education and whether education was received in the united states can explain a large share of the differences in the level of wages for immigrants from some countries it is found that more highly educated men assimilate more quickly the rate of economic progress has not improved for more recent arrivals from any country but this is most problematic among mexicans and central americans because of their relatively low rates of wage growth excerpt

towards a new complexity economics for sustainability some of the most important and urgent topics requiring economic analysis and policy advice are the problems of climate change and environmental sustainability and what can be done to alter corporate and individual behaviour to deal with these issues neoclassical economists tend to focus on market solutions such as carbon trading drawing on ideas of perfect rationality of actors and the appropriateness of marginal analysis to link such policies to the whole range of potential actions from legislative and regulatory to changing individual behaviours requires the economy and society to be analysed in its full complexity recognising that marginal analysis can be not just irrelevant but positively harmful when the need is for systemic shifts in economic and social trajectories this article draws upon a seminar series on complexity economics to consider how heterodox economic analysis can be brought to bear on the issue of the environment to develop a realistic policy agenda for change copyright oxford university press

the earnings of immigrant men in canada job tenure cohort and macroeconomic conditions using eleven cross sectional surveys spanning 1981 92 the authors compare the earnings of immigrant and native born men in canada apparently recent immigrant cohorts have suffered no decline in earnings job tenure is found to be a strongly significant determinant of earnings previous estimates of immigrant earnings differentials which have not incorporated job tenure information may partly reflect differences in tenure between immigrants and the native born when the sample is restricted to pairs of surveys that are close to the census survey years the estimates of cohort effects are sensitive to the choice of survey years one possible explanation for that sensitivity is suggested by the finding that macroeconomic conditions are a statistically significant determinant of the rate of assimilation of recent immigrants

current challenges of germany s energy transition project and competing strategies of challengers and incumbents the case of direct marketing of electricity from renewable energy sources electricity generated by renewable energies res e already accounts for 25 of germany s electricity supply this has led to recent discussions for a better market integration of res e the paper examines how competing actors and their ideas on market integration developed new services for direct marketing according to their respective origins and tried to shape the regulatory framework the paper analyses this process and explains the current shape of the field of direct marketing medium sized structured actors who favoured res e integration via the conventional wholesale power markets and who formed early close coalitions with res e power producers at the same time have been most successful in terms of market shares moreover they have been very successful for different reasons in building up coalitions with governance units and influencing the field rules and routines based on those findings the paper will conclude with some policy advices for the future adjustment of the current regulative frameworks as long as there is no evidence of how res e can be integrated most effectively and efficiently policies should maintain a competition between different direct marketing strategies to find out which strategies serve the best in terms of achieving a successful energy transition

governing sustainability transitions through business model innovation towards a systems understanding this paper examines the role of innovative business models in the transformation of socio technical systems focusing on decentralised energy technologies we explore business model innovation in the context of a transition towards a more sustainable energy system we conduct an empirical study of two energy services company esco models for the deployment of combined heat and power with district heating chp dh infrastructure in the uk based on these case studies we illustrate the different ways in which local authorities develop business models to create and capture value from more efficient resource use and to deploy sustainable technologies drawing from systems theories in the business model and socio technical literatures we analyse the interfaces between business models energy infrastructure and institutions we propose that a systems based approach to the analysis of business models as embedded in their socio technical contexts can offer new insights into the dynamics and governance of sustainability transitions

developing pathways for energy storage in the uk using a coevolutionary framework abstract a number of recent techno economic studies have shown that energy storage could offer significant benefits to a low carbon uk energy system as it faces increased challenges in matching supply and demand however the majority of this work has not investigated the real world issues affecting the widespread deployment of storage this paper is designed to address this gap by drawing on the systems innovation and socio technical transitions literature to identify some of the most important contextual factors which are likely to influence storage deployment specifically it uses a coevolutionary framework to examine how changes in ecosystems user practices business strategies institutions and technologies are creating a new selection environment and potentially opening up the energy system to new variations of storage for both electricity and heat the analysis shows how these different dimensions of the energy regime can coevolve in mutually reinforcing ways to create alternative pathways for the energy system which in turn have different flexibility requirements and imply different roles for storage technologies using this framework three pathways are developed user led decentralised and centralised which illustrate potential long term trajectories for energy storage technologies in a low carbon energy system

transition pathways for a uk low carbon electricity future abstract achieving long term targets for greenhouse gas emissions reductions such as the uk s legally binding target of reducing its emissions by 80 by 2050 will require a transition in systems for meeting and shaping energy service demands involving radical substitution to low carbon supply technologies and improvements in end use energy efficiency this paper describes the development and high level analysis of a set of transition pathways to a uk low carbon electricity system explaining key features of the core pathways developed and the distinctiveness and value of the approach the pathways use an action space concept to explore the dynamic interactions between choices made by actors which are influenced by the competing governance framings or logics that different actors pursue the paper sets out three core transition pathways market rules central co ordination and thousand flowers in which market government and civil society logics respectively dominate it summarises the key technological and institutional changes in these pathways and the roles of actors in bringing these about this leads to an identification of the key risks to the realisation of each of the pathways and of the challenges for individuals businesses social movements and policy makers in taking action to bring them about and sustain them

compulsive policy making the evolution of the german feed in tariff system for solar photovoltaic power abstract in recent years policy approaches that build upon the notion of innovation systems have enjoyed increasing attention in science technology and innovation policy but while the usefulness of systemic thinking in policy making has been demonstrated in a large number of empirical settings we still lack a detailed understanding of the dynamics at play when policy makers address systemic problems in this paper we show how complex interdependencies and the uncertain nature of technological change shape the process of targeted policy interventions in socio technical systems toward this end we analyzed the evolution of the german feed in tariff fit system for solar photovoltaic power a highly effective and widely copied policy instrument targeted at fostering the diffusion and development of renewable energy technologies we find that the policy has been subject to a considerable amount of changes many of which are the result of policy makers addressing specific system issues and bottlenecks interestingly however often these issues themselves were driven by unforeseen technological developments induced by previous policy interventions we argue that the pattern of policy serving as both a solution to and a driver of technological bottlenecks shows strong similarities with what rosenberg 1969 called compulsive sequences in the development of technical systems by shedding more light on how the characteristics of socio technical systems affect policy interventions our framework represents a first step toward more closely integrating the literature on innovation systems with the work on policy learning

supporting the externality of intermittency in policies for renewable energy abstract we analyse the joint problem of supporting renewables and resource adequacy in a liberalised electricity market and present a detailed model based comparison of two alternative policies we undertake this in the context of the british market we show how ceteris paribus the progressive replacement of coal with wind imposes extra costs of reserve and evaluate alternative way to meet this whether through capacity payments funded by customers or a reliability requirement on wind generators with capital cost or energy feed in subsidies we consider the reality of market concentration and the extent to which pragmatic regulation could allow prices to rise above marginal cost to reduce the extent of direct subsidies and complex market designs we also evaluate the implied cost of carbon reduction in a progressive replacement of coal with wind when the security is maintained by extra peaking gas we find that support through capital allowances rather than the energy market is more efficient

synergies and trade offs between governance and costs in electricity system transition affordability and costs of an energy transition are often viewed as the most influential drivers conversely multi level transitions theory argues that governance and the choices of key actors such as energy companies government and civil society drive the transition not only on the basis of costs this paper combines the two approaches and presents a cost appraisal of the uk transition to a low carbon electricity system under alternate governance logics a novel approach is used that links qualitative governance narratives with quantitative transition pathways electricity system scenarios and their appraisal the results contrast the dominant market led transition pathway market rules with alternate pathways that have either stronger governmental control elements central co ordination or bottom up proactive engagement of civil society thousand flowers market rules has the lowest investment costs by 2050 central co ordination is more likely to deliver the energy policy goals and possibly even a synergistic reduction in the total system costs if policies can be enacted and maintained thousand flowers which envisions wider participation of the society comes at the expense of higher investment and total system costs the paper closes with a discussion of the policy implications from cost drivers and the roles of market government and society
