an analysis of feed in tariff remuneration models implications for renewable energy investment recent experience from around the world suggests that feed in tariffs fits are the most effective policy to encourage the rapid and sustained deployment of renewable energy there are several different ways to structure a fit policy each with its own strengths and weaknesses this paper presents an overview of seven different ways to structure the remuneration of a fit policy divided into two broad categories those in which remuneration is dependent on the electricity price and those that remain independent from it this paper examines the advantages and disadvantages of these different fit models and concludes with an analysis of these design options with a focus on their implications both for investors and for society

competition and coalition formation of renewable power producers we investigate group formations and strategic behaviors of renewable power producers in electricity markets these producers currently bid into the day ahead market in a conservative fashion because of the real time risk associated with not meeting their bid amount it has been suggested in the literature that producers would bid less conservatively if they can form large groups to take advantages of spatial diversity to reduce the uncertainty in their aggregate output we show that large groups of renewable producers would act strategically to lower the aggregate output because of market power to maximize renewable power production we characterize the trade off between market power and generation uncertainty as a function of the size of the groups we show there is a sweet spot in the sense that there exists groups that are large enough to achieve the uncertainty reduction of the grand coalition but are small enough such that they have no significant market power we consider both independent and correlated forecast errors under a fixed real time penalty we also consider a real time market where both selling and buying of energy are allowed we validate our claims using pjm and nrel data

the philippine electricity sector reform and the urban question how metro manila s utility is tackling urban poverty in the early 2000s the philippine government reformed its electricity sector following neoliberal principles unbundling of the power industry privatisation of assets and commodification of electricity this paper shows that the reform was primarily driven by the need to secure electricity supply and cut down tariffs these national objectives ousted other issues and notably those that find their expression at the urban level among which the question of access to electricity in metro manila s urban poor communities the central state withdrew its attention from the issue of electrification and local actors had to react as they were confronted to social tensions and practices of pilferage as a consequence city governments and local administrations are getting involved in this issue which opens the way to participation of civil society this paper shows how the rolling back of the central state led to new partnerships and arrangements between the distribution utility local governments and community organisations this movement points to an urbanisation of energy issues which could bring positive results for end users provided that it is accompanied by a clearer regulatory framework

realising the wellbeing dividend an exploratory study using the human scale development approach abstract despite claims about the existence of the wellbeing dividend that sustainable and reduced consumption is compatible with increased wellbeing there is little evidence that this dividend is being realised the present research illustrates how through workshops addressing the cultural economic political and personal factors that impede or promote human need satisfaction a given society can unravel its own pathway towards sustainability and wellbeing this study draws on the wellbeing literature particularly max neef s approach to human needs and satisfiers it uses an analysis of group discussions in lleida a medium sized catalonian city to show how unsustainable consumption is associated with local hurdles for actualising needs and how sustainable consumption is linked to local descriptions of the utopian need actualising society the manner of progressing towards need actualisation and sustainability is also addressed by participants who identify the changes in norms institutions and personal identity that need to be in place the analysis reveals the interrelatedness of satisfiers and argues for a systemic perspective to address social transition towards sustainability and wellbeing at the local level

towards a sustainable electrification in ghana a review of renewable energy deployment policies abstract ghana has been facing perennial power rationing over the years due to fuel supply challenges the country s energy system is likely to suffer additional strain from rising energy demand fueled by population growth rapid urbanization and economic development fortunately there are enormous renewable energy resources which can provide sustainable electrification as backbone to socioeconomic development while curbing global warming ghana s energy strategy targets 100 access to electricity and 10 share of sustainable power in national generation mix by 2020 despite the existence of numerous policies and a renewable energy act current contribution of non conventional renewable energy to electricity generation is less than 1 the right mix of policies to address the unique domestic conditions and achieve its specific development goals remains insufficient this study reviews the regulatory framework financing incentives and other provisions of ghana s renewable energy act it critically examines the policy s strengths weaknesses opportunities and treats based on comparative analysis and lessons drawn from failed and successful implementation of similar policies around the world the study also assesses the impact of policy on project development it was found that the performance of ghana s renewable energy policy on grid connected electricity has been poor compared to its target the fundamental reasons for this unsatisfactory performance may be attributed to partial implementation of policies lack of market driven support schemes lack of pricing policy framework weak grid network limited access to funds and inconsistencies in renewable energy development strategies this study proposes the following countermeasures i ghana should comprehensively harmonize renewable energy regulatory and fiscal policies with domestic electricity pricing regime ii market driven support schemes should be prioritized for cost effectiveness and minimum governmental influence these reforms can help eliminate some of the major barriers to sustainable electrification in ghana while the lessons provide a learning curve for other african countries

the newsvendor game has a nonempty core we settle an open conjecture regarding the newsvendor game we prove that its core is always non empty for all possible joint distributions of the random demands we give sufficient conditions under which the core is a singleton or it contains non negative elements

pricing and the news vendor problem a review with extensions in the newsvendor problem a decision maker facing random demand for a perishable product decides how much of it to stock for a single selling period this simple problem with its intuitively appealing solution is a crucial building block of stochastic inventory theory which comprises a vast literature focusing on operational efficiency typically in this literature market parameters such as demand and selling price are exogenous however incorporating these factors into the mode l can provide an excellent vehicle for examining how operational problems interact with marketing issues to influence decision making at the firm level in this paper we examine an extension of the newsvendor problem in which stocking quantity and selling price are set simultaneously we provide a comprehensive review that synthesizes existing results for the single period problem and develop additional results to enrich the existing knowledge base we also review and develop insight into a dynamic inventory extension of this problem and motivate the applicability of such models

stochastic security for operations planning with significant wind power generation in their attempt to cut down on greenhouse gas emissions from electricity generation several countries are committed to install wind power generation up to and beyond the 10 20 penetration mark however the large scale integration of wind power represents a challenge for power system operations planning because wind power 1 cannot be dispatched in the classical sense and 2 its output varies as weather conditions change this warrants the investigation of alternative short term power system operations planning methods capable of better coping with the nature of wind generation while maintaining or even improving the current reliability and economic performance of power systems to this end this paper formulates a short term forward electricity market clearing problem with stochastic security capable of accounting for nondispatchable and variable wind power generation sources the principal benefit of this stochastic operation planning approach is that when compared to a deterministic worst case scenario planning philosophy it allows greater wind power penetration without sacrificing security

renewable energy policies in promoting financing and investment among the east asia summit countries quantitative assessment and policy implications many countries have implemented various policies for renewable energy development ranging from setting power purchase agreements and the legislation of renewable energy requirements to providing incentives and imposing carbon taxes the evaluation of the effectiveness of such policies however is fragmented which raises a need for a comprehensive analysis this paper aims to assess whether and how policies promoting renewable energy investment have achieved the intended goals it employs five broadly defined criteria market uncertainty profitability technology and financial resources to build an index to assess respectively if such policies have helped create a market for renewable energy maximize potential profits reduce risks relating to the investment develop and adopt new technologies and improve the access to financial resources each criterion is reflected by three indicators values of each indicator are converted into ordinal values for analysis the index not only scans comprehensively all relevant renewable energy investment policies in the east asia summit countries but also provides systematic and quantitative measures to compare the effectiveness of policies in these countries with respect to the creation of market the degree of uncertainty the potential of profitability the development and adoption of technology and the accessibility of financial resources

trading wind generation in short term energy markets even with state of the art forecasting methods the short term generation of wind farms cannot be predicted with a high degree of accuracy in a market situation these forecasting errors lead to commercial risk through imbalance costs when advance contracting this situation is one that needs to be addressed due to the steady increase in the amount of grid connected wind generation combined with the rise of deregulated market orientated electricity systems in the presence of imbalance prices and uncertain generation a method is required to determine the optimum level of contract energy to be sold on the advance markets such a method is presented here using markov probabilities for a wind farm and demonstrates substantial reductions in the imbalance costs the effect of market closure delays and forecasting window lengths are also shown

renewable energy policies for sustainable development in cambodia in line with sustainable development path electrification with the aid of renewable energy resources is a key element for the developing countries cambodia with almost 85 rural population is one of the countries with high renewable energy resources but at the same time has a low installed capacity in the context of this study the potential and status of sustainable energy generation in cambodia are studied in detail the renewable energy policies strategies and programs are investigated and the implemented projects based on the determined policies are reviewed considering the existing governmental policy of enabling 70 of rural households to reach reliable electricity services by 2030 the renewable energy resources are found as the best option for rural electrification the economic regulatory financial and institutional barriers are shown as the main cause of the significant deviation between the potential and installed capacity it is essential to overcome the challenges in order to achieve a sustainable development in rural electrification in cambodia

demand response application by strategic wind power producers this paper considers a wind power producer playing strategically in a day ahead market while willing to set demand response dr contracts with a dr aggregator to this end a bilevel problem including a single leader and two followers is formulated the wind power producer is the leader aiming at maximizing its profit through offering into a day ahead market and clearing its deviation in a balancing market the strategic behavior of the producer in the day ahead market is modeled through the market clearing process follower 1 in addition the dr aggregator behavior is modeled through a revenue function in which the aggregator is able to sell its dr product to the wind power producer other competitors and the day ahead market follower 2 the overall problem is a stochastic mathematical program with equilibrium constraints mpec in which wind power production and imbalance prices are associated with uncertainty the problem is then transformed into a linear programming approach a case of the nordic market is chosen to assess the validity of the given problem

effects of financial development economic growth and trade on electricity consumption evidence from post fukushima japan abstract this study examines the long run and short run effects of financial development economic growth export imports and capital on the japanese energy predicaments as a result of the foregoing energy crisis in the country to ensure a robust outcome the study applied the extended cobb douglas production function and used time series data from 1970 to 2012 following to this structural break unit root test ardl bounds test approach to cointegration and the johansen cointegration test were applied in addition the vecm granger causality framework was used in determining the causal relationship between the variables the findings of the study establish that in the long run a 1 rise in financial development economic growth exports and imports in japan will exert a significant pressure on the japanese electricity consumption by 0 2429 0 5040 0 0921 and 0 2193 respectively however capital was found to decline energy consumption in all material respect in the short run the study discovered how a 1 rise in the dynamics of financial development economic growth exports and imports to add to the japanese electricity predicaments by 0 2210 0 5840 0 0521 and 0 2031 respectively the existence of the feedback relationship between most of the variables was discovered while economic growth exports imports and trade openness were found to granger cause electricity consumption the study advocates the adoption of massive but competitive renewable energy system in japan how it should be done and why it should be done are carefully set by this study

coalitional aggregation of wind power this paper explores scenarios in which independent wind power producers form willing coalitions to exploit the reduction in aggregate power output variability obtainable through geographic diversity in the setting of a two settlement electricity market we examine the advantage gained through optimal coalitional contract offering strategies for quantity risk reduction we show that a group of independent wind power producers can always improve their expected profit by cooperatively offering their aggregated power using coalitional game theory we identify sharing mechanisms to fairly allocate the profits to coalition members we show that the resulting coalitional game is balanced guaranteeing that the core of the game is necessarily nonempty in addition we propose a profit sharing mechanism that minimizes the worst case dissatisfaction to recover an imputation in the core finally we illustrate our theoretical results with empirical studies using data from five representative wind farms in upstate new york

bringing wind energy to market wind energy is a rapidly growing source of renewable energy generation however the current extra market approach to its assimilation into the electric grid will not scale at deep penetration levels in this paper we investigate how an independent wind power producer might optimally offer its variable power into a competitive electricity market for energy starting with a stochastic model for wind power production and a model for a perfectly competitive two settlement market we derive explicit formulae for optimal contract offerings and the corresponding optimal expected profit as wind is an inherently variable source of energy we explore the sensitivity of optimal expected profit to uncertainty in the underlying wind process we also examine the role of forecast information and recourse markets in this setting we quantify the role of reserves in increasing reliability of offered contracts and obtain analytical expressions for marginal profits resulting from investments in improved forecasting and local auxiliary generation the formulae make explicit the relationship between price signals and the value of such firming strategies

luxury or lock in an exploration of unsustainable consumption in the uk 1968 to 2000 abstract sustainable consumption demands the ability to understand the patterns of resource consumption associated with changing lifestyles this paper explores changes in resource consumption patterns in the uk between 1968 and 2000 using an environmental input output model the paper tracks the fossil resource requirements attributable to 8 high level functional purposes and finds that overall fossil resource consumption increased 35 over the 32 year period the four functional purposes most closely related to the provision of basic material needs showed little change over the period the bulk of the increase in fossil resource requirements was attributable to two specific functional purposes 1 recreation and entertainment 2 commuting and business travel the authors discuss the relevance of these findings for the continuing debate over the question whether rising consumption is being driven by expanding social aspirations luxury or whether it is the result of structural lock in

minimization of imbalance cost trading wind power on the short term power market present power markets are designed for trading conventional generation for wind generation to participate in a short term energy market lengthy wind power production forecasts are required although wind speed forecasting techniques are constantly improving wind speed forecasts are never perfect and resulting wind power forecast errors imply imbalance costs for wind farm owners in this paper a new method for minimization of imbalance costs is developed stochastic programming is used to generate optimal wind power production bids for a short term power market a wind power forecast error is represented as a stochastic process the imbalance costs resulting from this strategy are then compared to the case when wind power production bids on a short term power market are based directly on a wind speed forecast

post neoliberal electricity market re reforms in argentina diverging from market prescriptions this paper focuses upon the policy and institutional change that has taken place within the argentine electricity market since the country s economic and social crisis of 2001 2 as one of the first less developed countries ldcs to liberalise and privatise its electricity industry argentina has since moved away from the orthodox market model after consumer prices were frozen by the government in early 2002 when the national currency was devalued by 70 although its reforms were widely praised during the 1990s the electricity market has undergone a number of interventions ostensibly to keep consumer prices low and to avert the much discussed energy crisis caused by a dearth of new investment combined with rising demand levels this paper explores how the economic crisis and its consequences have both enabled and legitimised these policy and institutional amendments while drawing upon the specifics of the post neoliberal market re reforms to consider the extent to which the government appears to be moving away from market based prescriptions in addition this paper contributes to sector specific understandings of how despite these changes neoliberal ideas and assumptions continue to dominate argentine public policy well beyond the postcrisis era

the development of renewable energy power in india which policies have been effective abstract the international energy agency has identified the development of renewable energy sources as a key element to mitigate climate change at the same time it has projected india to be the second largest contributor to the increase in global energy demand to 2035 india hence faces a significant challenge to ensure its energy security by diversifying its power generation mix in the wake of the creation of a green climate fund in cancun this paper studies empirically the effect of the introduction of the electricity act 2003 and the tariff policy 2006 as well as the implementation of feed in tariffs and minimum quotas on clean electricity sourcing on the development of grid connected renewable energy power in nine indian states over the period 2001 2009 results suggest that the passing of the tariff policy 2006 state level policies quantity based instruments and a greater participation of the private sector have played a key role in promoting the development of installed capacity from renewable energy power in the nine states of the sample

optimal bidding of a group of wind farms in day ahead markets through an external agent in deregulated electricity markets producers offer their energy to the day ahead market as the subsidies for renewable producers are becoming lower and lower they have to adapt to market prices this paper models the energy trading in the day ahead market for wind power producers different strategies are proposed for this purpose 1 several wind farms offering their energy separately to the day ahead market 2 the same strategy as in 1 but compensating the imbalance among different wind farms and 3 a joint offer involving several wind farms through an external agent in order to minimize the imbalances between the offer and the final power generation the strategies are modeled with stochastic mixed integer linear programming and conditional value at risk is used to consider the risk assessment the expected profit including risk aversion is maximized for each wind power producer and for the set of wind power producers in the case of a joint offer a comparison of the different cases is described in detail in a case study and relevant conclusions are provided

willing consumers or locked in policies for a sustainable consumption postmodern explanations of consumer behaviour stress social and psychological factors to the neglect of explanations based on structural issues such as the working life conditions which favour a work and spend lifestyle the conditions of urban living or the effects of pervasive marketing this paper argues that consumers may not be so keen and willing but are rather locked in by circumstances some of these circumstances are deliberately created by other interests and a policy to limit consumption must look for adequate means over a large and varied field in the end shorter working hours may be an important key to a more sustainable future 2002 elsevier science b v all rights reserved

vietnam s energy sector a review of current energy policies and strategies abstract since the introduction of market oriented economy in 1986 vietnam has made noticeable socio economic progress in this progress the energy sector has played a vital role this role is likely to deepen in the years to come as vietnam strives to achieve even higher levels in economic progress such deepening in the role of energy this paper argues will heighten concerns about the security of energy supply and economic environmental social and political consequences in order to address these issues vietnam has over the last decade developed a suite of energy policies a deeper review of these policies suggests that they are typified by economic growth orientation exclusive focus on a single sector or single issue and largely neglect the significance of cross sectoral and cross thematic issues arising from the interdependencies between energy economy and the polity at large the existing energy policy settings are therefore unlikely to be able to provide a satisfactory redress to the challenges noted above this paper provides an overview of the current energy policies with a view to identify areas where further policy effort is needed in order to facilitate a sustainable development of the vietnamese energy sector

status and perspectives of renewable energy policy and deployment in the european union what is needed to reach the 2020 targets abstract this article evaluates the status of current res deployment policies and barriers in the eu 27 member states and compares it to the required to meet the 2020 targets the evaluation relies strongly on the quantitative deployment status and policy effectiveness indicators european res deployment and policy has progressed strongly in recent years but the growth here has been mainly driven by effective policies in a small or medium number of top runner countries across europe the highest average policy effectiveness over six years was reached for onshore wind 4 2 biofuels 3 6 and biomass electricity 2 7 while in the heat sector all technologies score below 2 comparing the recent progress to the required growth for meeting the 2020 target it appears that some countries largely exceed the interim targets of the res directive 2009 28 ec despite this europe will need additional policy effort to reach the 2020 target critical success factors include implementing effective and efficient policies that attract sufficient investments reducing administrative and grid related barriers especially in currently less advanced countries upgrading the power grid infrastructure dismantling financial barriers in the heat sector realising sustainability standards for biomass and lowering energy demand through increased energy efficiency efforts

wind power offering strategy in day ahead markets employing demand response in a two stage plan this paper deals with wind power offering strategies in day ahead markets a new plan is proposed in which a wind power producer participates in the day ahead market while employing demand response dr to smooth its power variations in this context a new dr scheme is presented through which the wind power producer is able to achieve dr by establishing various dr agreements with dr aggregators the proposed offering plan involves two stages the first stage clears on the day ahead market the wind power producer decides on day ahead offers as well as dr agreements with the aggregator the second stage takes place on the balancing market in a successive approach the wind power producer determines its energy trading for each period until the whole day is covered additionally proper dr agreements for each period are confirmed here the proposed plan is formulated in a stochastic programming approach where its validity is assessed on a case of the nordic market

consumption sustainable welfare and human needs with reference to uk expenditure patterns between 1954 and 1994 abstract this paper explores the complex relationship between economic consumption and human welfare or well being conventional economics suggests that increasing levels of economic consumption lead to increasing levels of well being however this view has been criticised on both environmental and social grounds on the one hand the material impacts of increasing consumption are environmentally unsustainable on the other hand material consumption can conflict with crucial social and psychological components of human welfare this paper develops a perspective on human welfare which is based on max neef s characterisation of human needs it discusses the implications of this alternative perspective for the conventional viewpoint and illustrates the importance of it with reference to patterns of consumer expenditure in the uk over the last 40 years the authors suggest that from this perspective modern societies may be seriously adrift in their pursuit of human well being however they also point out that addressing this situation provides far more opportunity for ecologically sustainable development than is generally recognised

trading wind generation from short term probabilistic forecasts of wind power due to the fluctuating nature of the wind resource a wind power producer participating in a liberalized electricity market is subject to penalties related to regulation costs accurate forecasts of wind generation are therefore paramount for reducing such penalties and thus maximizing revenue despite the fact that increasing accuracy in spot forecasts may reduce penalties this paper shows that if such forecasts are accompanied with information on their uncertainty i e in the form of predictive distributions then this can be the basis for defining advanced strategies for market participation such strategies permit to further increase revenues and thus enhance competitiveness of wind generation compared to other forms of dispatchable generation this paper formulates a general methodology for deriving optimal bidding strategies based on probabilistic forecasts of wind generation as well as on modeling of the sensitivity a wind power producer may have to regulation costs the benefits resulting from the application of these strategies are clearly demonstrated on the test case of the participation of a multi mw wind farm in the dutch electricity market over a year

introduction to the special issue urban energy governance local actions capacities and politics introduction to a special issue showing how there is much to be gained for deeper understandings of energy policy from a specifically urban analysis of rationales forms and repercussions of energy systems in transition the special issue offers an in depth examination of the variety of urban responses to quite distinctive and sometimes competing energy related challenges

estimating the co2 abatement cost substitute price of avoiding co2 emission spae by renewable energy s feed in tariff in selected countries abstract many renewable energy policies are looking into new incentives to absorb investments by targeting abating co 2 emission and fixing energy price fluctuation feed in tariff fit is a policy for rebating the amount of generated renewable electricity to investor fit is also defined as a co 2 mitigation policy in electricity generation from renewable sources this paper presents a cost benefit survey that estimates the real produced carbon dioxide for electricity generation in selected countries this study introduces the substitute price of avoiding co 2 emission as an indicator the new indicator shows how much is paid for avoiding co 2 by each selected countries through the fit policy for renewable technologies the amount calculated for solar energy is taken as a case in this paper the result confirms that the fit policy reasonably works for solar energy in absorbing investment however the fit policy claims a large portion of liquidity compared with other approaches hence makes this mechanism inept as a co 2 mitigation policy

renewable energy diffusion in asia can it happen without government support the dramatically increasing population of asia necessitates equally as dramatic increase in energy supply to meet demand rapidly increasing energy demand is a major concern for asian countries because the increase in demand is being met through the increased use of fossil fuel supply largely domestic coal and imported fuel renewable energy supply presents a lower emission pathway that could be a viable option for steering off the higher emissions path however several market economic institutional technical and socio cultural barriers hinder countries in moving from high to low emission pathway following a discussion on the rising demand for energy in asia and the prospects of partly satisfying it with renewable energy we outline the reasons for government support to tackle the barriers for widespread diffusion of grid based renewable energy additionally we also discuss workable models for strategic government intervention to support diffusion of grid based renewable energy in asia

potentials and challenges in implementing feed in tariff policy in indonesia and the philippines abstract located in southeast asia indonesia and the philippines are characterized by a tropical climate and high amounts of rainfall that render their high potential for hydro power and wind energy deployment the volcanic geography of both countries also indicates their high geothermal potential compared with that of other countries and their high solar radiation level makes them suitable areas to establish power plants the present study is an archival statistical overview of the potential generation of renewable energy in indonesia and the philippines and the implementation of the feed in tariff fit policy this research focuses on the challenges encountered by politicians and policymakers and confirms the insufficient production of energy from wind solar and bio gas sources despite the potential and the attempts to deploy fit results show that the role of the government in providing support to investors is not clear in both countries in addition inflation rates have not been calculated however fit has benefitted both countries by preventing degression during the primary years

which renewable energy policy is a venture capitalist s best friend empirical evidence from a survey of international cleantech investors governments around the world have adopted ambitious targets to increase the share of renewable energy and reduce greenhouse gas emissions they pursue a variety of policy approaches to achieve these targets it has been a popular theme for contributions in energy policy to investigate the effectiveness of such policies this article adds a new perspective to the debate namely looking at the policy preferences of private investors in innovative clean energy technology firms we surveyed 60 investment professionals from european and north american venture capital and private equity funds and asked them to assess the effectiveness of various policies in terms of stimulating their interest to invest in innovative clean energy technologies in addition to quantitative rankings we use qualitative interview data to capture additional information on why investors prefer some policies over others the combined analysis compensates for the inherent limitations of a quantitative ranking using generic policy types the results of this exploratory analysis demonstrate that all other things being equal investors in our sample perceived feed in tariffs to be the most effective renewable energy policy the overall preference for feed in tariffs is even more pronounced among investors based in europe and with higher exposure to clean energy

review of co2 price in europe using feed in tariff rates abstract the price of carbon emitted by thermal plants has always been a favorite topic of researchers and policy makers a substitute price for co2 is calculated in this study based on real time payments through government tariffs these payments aim to mitigate co2 emission caused by unregulated electricity generation the total co2 produced by the thermal plants of 10 european countries is shown in this study the government s payment for each technology is utilized to clear the final co2 abatement cost the substitute price of avoiding co2 emission spac for each technology and country is estimated spac is basically the price that each country pays to avoid producing co2 the conducted survey shows that the spac of the 10 european countries ranges from 63 to 2951 euros depending on the type of technology used and the country s policy results confirm a competitive payment by governments only for german and uk hydro and uk wind technologies comparison of the countries payments for renewable energies and co2 market price shows that governments incurred an inefficient payment of liquidity as a carbon mitigation policy

planning to forget informal settlements as forgotten places in globalising metro manila as metro manila s economy has become increasingly integrated into global flows of trade and investment it has also experienced a shelter crisis as the number of people who cannot afford legal housing and consequently illegally settle in informal settlements has increased in both absolute and percentage terms this paper discusses such informal settlements as forgotten places in the global era it makes two arguments first it argues that this shelter crisis is inherent to globalising cities in developing countries as a contradiction emerges between the extensive redevelopment and rising property values that accompany global city development and the shelter needs of low income people the second is that informal settlements have increasingly been forgotten by urban planners despite this housing crisis as planners have consciously abandoned place based poverty alleviation efforts based on the rationale that they are no longer tenable in the global era

overall review of renewable energy subsidy policies in china contradictions of intentions and effects abstract china is vast abundant and particularly plentiful in energy sources due to which it has obtained remarkable achievements on economy however its energy structure is too simple to support the sustainable development of economy as coal still contributes to the majority of energy consumption in china as a consequence renewable energy law was enacted in 2005 and chinese government announced a series of policies to boom renewable energy industry subsidy policy is one of the major forms of these policies this paper aims to present these subsidy policies and to analyze their effects according to relative data in energy industry 2005 2013 to find out the deficiencies and enlighten possible policy improvements the original intentions and abstracts of 5 different levels of subsidy related policies are summarized and the effects in reality are attentively analyzed it can be concluded that subsidy policies have different short term effect on different renewable energies and they all show some negative effect to a certain extent 6 core problems are summarized in this paper and remedy strategies are suggested

managing the energy trilemma the case of indonesia abstract this article argues that a central challenge for energy governance is how to manage a complex energy trilemma involving the sometimes competing demands of energy security climate change mitigation and particularly in developing countries energy poverty it suggests that tensions between the horns of the trilemma in large part explain indonesia s current profoundly suboptimal energy policy while these tensions are not inherently incapable of resolution such resolution would require good governance at both state and global levels the possibilities for and obstacles confronting such governance are explored and provisional solutions canvassed

modelling the treatment effect of renewable energy policies on economic growth evaluation from mena countries abstract this paper investigates the effects of renewable energy re policies on economic growth in mena countries using the propensity score matching methodology our empirical analysis conducted on a sample of 24 economies 17 re and 7 non re countries from 1980 to 2012 shows that the treatment effect of re policies has a significant and positive impact on stimulating and promoting economic growth in mena economies that have implemented these energy policies re policies alone however are not sufficient this change requires the collective long term commitment of all stakeholders including governments citizens financiers private companies and international agencies this would help impede policy overlaps and incoherence as well as consequently improve the overall policy effectiveness

opportunity cost bidding by wind generators in forward markets analytical results wind generation must trade in forward electricity markets based on imperfect forecasts of its output and real time prices when the real time price differs for generators that are short and long the optimal forward strategy must be based on the opportunity costs of charges and payments in real time rather than a central estimate of wind output we present analytical results for wind s optimal forward strategy in the risk neutral case the optimal strategy is determined by the distribution of real time available wind capacity and the expected real time prices conditioned on the forward price and wind out turn our approach is simpler and more computationally efficient than formulations requiring specification of full joint distributions or a large set of scenarios informative closed form examples are derived for particular specifications of the wind price dependence structure in the usual case of uncertain forward prices the optimal bidding strategy generally consists of a bid curve for wind power rather than a fixed quantity bid a discussion of the risk averse problem is also provided an analytical result is available for aversion to production volume risk however we doubt whether wind owners should be risk averse with respect to the income from a single settlement period given the large number of such periods in a year

renewable energy in eastern asia renewable energy policy review and comparative swot analysis for promoting renewable energy in japan south korea and taiwan abstract japan south korea and taiwan are deficient of domestic fossil energy sources and depend significantly on imported fuels since the oil shock in the 1970s all three countries have promoted renewable energy as an alternative energy source to improve energy security currently renewable energy is being promoted to build low carbon economies this study reviews the development of renewable energy policies and roadmaps it also examines and compares strengths weaknesses opportunities and threats swot of these countries in the context of advancing renewable energy policies and technologies and expanding domestic renewable energy installations as well as strategically positioning themselves in the international renewable energy market as exporters of clean energy technologies through the swot analysis this paper identifies a capacity for additional renewable energy deployment in these countries and highlights the necessity of increased cooperation between the three countries to strengthen their domestic and regional renewable energy sectors and compete in the global renewable energy market in the post fukushima era

wind aggregation via risky power markets aggregation of diverse wind power sources can effectively reduce their uncertainty and hence the cost of wind energy integration a risky power contract is proposed by which wind power producers wpps can trade uncertain future power for efficient wind aggregation a two settlement market with both the risky power contract and a conventional firm power contract is shown to have a unique competitive equilibrium ce characterized in closed form the marginal contribution and diversity contribution of each wpp to the group of all wpps are fairly reflected in the profit earned by this wpp at the ce moreover the ce achieves the same total profit as achieved by a grand coalition of wpps in a coalitional game setting the profit allocation induced by the ce is always in the core and is achieved via a non cooperative risky power market the benefits of the risky power market are demonstrated using wind generation and locational marginal price data for ten wpps in the pjm interconnection

towards a systemic development approach building on the human scale development paradigm abstract since its inception the scope of inquiry within modern economics has been overall reduced to the chrematistic market centred dimension of the economic process this has been reflected in the very way it shaped the modern idea of development which more and more has been represented in monetary terms to the point of being equated to chrematistic growth altogether this reductionism has been severely criticized for various reasons mostly related to the ignorance of the complex multidimensional social cultural and psychological motives and aspirations of human beings ignoring as well crucial environmental and ecological dimensions within and by means of which the economic process unfolds one fundamental early contribution to the re conceptualization of the economic development process in terms of well being from a systemic perspective came about with the human scale development approach h sd in the 1980s central to this paradigm is a systemic re conceptualization of human needs and an attempt to place this discussion at the centre of the development debate it suggested a recovery of the oikonomy in its original classical meaning as a means for achieving better well being beyond the chrematistics narrow scope this theory presents a very wide outlook for its theoretical and practical applications and in this paper we will try to build on h sd s original contribution we begin this by briefly outlining what can be termed the chrematistic turn within both modern economics theory and practice at the dawn of modern capitalism in the second section the main aspects of the h sd approach are briefly presented and discussed the last sections are devoted to propose some methodological extensions to the original h sd version suggesting innovative ways of enlarging its scope through the development and improvement of its evaluation tools thereby we hope to enhance its application within its traditional context as well as indicating means for applying it to other fields as development policies strategies or eventually appraisal of new technologies

impact of public policy uncertainty on renewable energy investment wind power and the production tax credit abstract it is generally understood that the pattern of repeated expiration and short term renewal of the federal production tax credit ptc causes a boom bust cycle in wind power plant investment in the us this on off pattern is detrimental to the wind industry since ramp up and ramp down costs are high and players are deterred from making long term investments it is often assumed that the severe downturn in investment during off years implies that wind power is unviable without the ptc this assumption turns out to be unsubstantiated this paper demonstrates that it is not the absence of the ptc that causes the investment downturn during off years but rather the uncertainty over its return specifically it is the dynamic of power purchase agreement ppa negotiations in the face of ptc renewal uncertainty that drives investment volatility with contract negotiations prevalent in the renewable energy industry this finding suggests that reducing uncertainty is a crucial component of effective renewable energy policy the ptc as currently structured is not the only means existing or potential for encouraging wind power investment using data from a survey of energy professionals various policy instruments are compared in terms of their perceived stability for supporting long term investment

electricity market participation of wind farms the success story of the spanish pragmatism abstract in the last 10 years more than 15 gw of wind power asociacion empresarial eolica spanish wind energy association nota de prensa press release 17 de enero de 2008 http www aeeolica org doc np 080117 espana supera los 15000 mw eolicos pdf have been installed in spain of which more than 3 5 gw in 2007 furthermore plans are to reach 20 gw by 2010 and there are expectations of an installed capacity exceeding 40 gw by 2020 this article will present the innovative solutions for technical and economical integration that allow to reach such high level wind penetration objectives the system peaks at around 44 gw and is almost isolated it will be described how the regulation has evolved from a pure feed in tariff to a market premium option where technical and economic integration has been a priority today approximately 97 of installed wind capacity accesses the spanish wholesale electricity market market integration has been crucial sending the correct signals to participants to look for the optimum technical solutions technical improvements have come from both wind power producers fault ride through capabilities visibility and controllability of wind power power production forecasting reactive power control and the system operator specific control centre dedicated to renewable energy sources res new security analysis tools gaining technical confidence of wind capabilities

demise of the standard model for power sector reform and the emergence of hybrid power markets following earlier reforms in the power sectors of industrialized countries and emerging markets e g chile developing countries were encouraged to unbundle their electricity industries and to introduce competition and private sector participation this paper highlights the developments that led to how power sector reform came to be defined as a standard model and theoretical framework in its own right and how the model was used prescriptively in many developing countries however we also show that after more than 15 years of reform efforts this new industry model has not fully taken root in most developing countries finally we identify and characterize the emergence of new hybrid power markets which pose fresh performance and investment challenges

an analysis of compensation in the u s venture capital partnership abstract venture capital limited partnerships are an attractive arena to study cross sectional and time series variations in compensation schemes we empirically examine 419 partnerships the compensation of new and smaller funds displays considerably less sensitivity to performance and less variation than that of other funds the fixed base component of compensation is higher for younger and smaller firms we observe no relation between incentive compensation and performance our evidence is consistent with a learning model in which the pay of new venture capitalists is less sensitive to performance because reputational concerns induce them to work hard

cost causation based allocations of costs for market integration of renewable energy an important problem in modern electrical power systems is the inherent variability and uncertainty of renewable energy resources allocating the costs generated by the variable resources in a just and reasonable manner is crucial for economic efficiency in this paper we develop an axiomatic framework for allocating the deviation costs generated by variable resources using the cost causation based principle the cost causation principle has a long historical tradition in electrical energy systems and has been proved to provide economic efficiency we apply the new cost causation based framework to allocate the cost in the production deviation of a group of renewable energy producers and thereby help promote the market integration of renewable energy the resulting cost allocation framework is then applied to five wind power producers bidding in the iberian electricity market in europe using real data on wind speeds and market prices
