role of carbon swap trading and energy prices in price correlations and volatilities between carbon markets the present paper theoretically and empirically examines the role of carbon swap trading and energy prices in volatilities and price correlations between the eu and kyoto protocol emissions trading schemes a supply and demand based correlation model between eua and scer price returns is proposed in detail using inverse box cox type marginal abatement cost mac curves and simple emission reduction volume processes the model includes financial players eua scer swap transaction in boom periods of carbon prices using the logit model for eua and eua scer swap volume correlations and stronger energy price impacts on eua prices than scer prices using a mean reverting lognormal process for energy prices the empirical studies using eua and scer prices estimate the model parameters resulting in a positive eua volume impact on eua scer swap transactions and a positive energy price impact on eua prices it is shown that high eua scer price correlations during high eua price periods stemmed from eua scer swap transactions whereas high eua scer price correlations during the period of financial turmoil with low eua prices came from the drop in energy prices we also show that the leverage effects often observed in security markets exist in both the eua and scer markets according to the price volatility relation

the distance to competitive balance a cardinal measure competitive balance is a key variable in the analysis of sports competitions there are several indexes that measure competitive balance but either they are not a mathematical metric or they do no

electricity planning and implementation in sub saharan africa a systematic review abstract universal electricity access is an important development objective and the focus of a number of key global un initiatives while robust electricity planning is widely believed to be a prerequisite for effective electrification to date no comprehensive overview of electricity planning research has been undertaken on sub saharan africa the world region with the lowest access rates this paper reviews quantitative and qualitative electricity planning and related implementation research considering each of the 49 sub saharan african countries the four regional power pools and the sub continent as a whole applying a broad understanding of electricity planning and a practical limit of 20 reviewed articles per country and region 306 relevant peer reviewed journal articles are included in this review a general classification scheme is introduced that classifies the planning literature along the addressed value chain depth number of different analysed criteria and number of evaluated decision alternatives the literature is found to be strongly clustered in a few countries with less than 5 identified relevant articles in 36 of the 49 countries the total amount of articles per year is clearly increasing over time addressing technology choice operation distribution and implementation analyses although including different high level criteria in analysing electricity systems is common the literature is only starting to use formalised multi criteria decision making mcdm tools the review indicates that 63 of relevant articles favour renewable energy technologies for their given problems frequently mentioned success factors for electrification in sub saharan africa include adequate policy design sufficient finance and favourable political conditions while considerable regional and methodological literature gaps are apparent the literature in this review identifies a rich and fruitful ground for future research to fill these gaps

flexibility in the market for international carbon credits and price dynamics difference with european allowances the paris agreement establishes a mechanism to allow a party to benefit from greenhouse gases emissions reductions conducted in a host party to fulfil its nationally determined contribution in this context the objective of this paper is to improve the understanding of carbon offsets price dynamics in comparison with regular carbon markets allowances we combine a cointegration approach with risk premium considerations to compare the price dynamics of european union allowances eua and certified emission reductions cer in the second phase of the european carbon market by taking account of breaks identified in the series we find that while the eua and cer returns present comparable dynamics the long term relationships between the price of these two types of permits and their drivers differ significantly given the impact of energy prices positive for coal and negative for gas on the cer price we suggest the existence of a supply side effect for credits we find that the price elasticity of allowances with regard to the coal and gas prices is negative in time periods of low economic activity and positive in the rest of the time we explain the latter by the fact that the market is not tight and the former by the effect of the economic activity on the price of commodities and energy

the market for tradable ghg permits under the kyoto protocol a survey of model studies abstract this paper gathers results from 25 models of the market for tradable greenhouse gas ghg emission permits under the kyoto protocol due to diverging projections of emissions growth and different modeling approaches the model results differ substantially the average market volume is approximately 17 and 33 billion usd under global trading and annex b trading respectively including non carbon ghg lowers compliance costs and permit prices in the absence of the us permit demand roughly equals hot air from the former soviet union these countries can increase their revenues from selling permits by restricting supply which raises the permit price

carbon pricing and electricity markets the case of the australian clean energy bill abstract we examine the impact of the clean energy bill on the price behavior of electricity futures contracts in the australian national electricity market first we compute ex ante forward risk premiums in the pre tax period until june 2012 then derive market implied expectations about additional costs of the carbon pricing mechanism cpm on generators as well as pass through rates during the carbon tax july 2012 june 2014 and post tax after july 2014 periods our results suggest that the observed carbon premiums became increasingly higher once the carbon tax had been proposed and subsequently legislated in 2011 during periods where market participants could be relatively certain that the tax would be effective we find expected carbon pass through rates between 67 and 150 which seem to be inversely related to emission intensities in the regional markets our results are also a clear indication of strong policy uncertainty with regards to the cpm and suggest that in the future a stable and long term policy framework would be required for a carbon pricing mechanism to have its full effect

prospective measures of competitive balance application to money lines in major league baseball this study examines competitive balance in major league baseball mlb by looking at the money lines for the games during the regular season the assertion is that the closer the money lines are to indicating that each team has an equal chance of winning each game the more competitive balance there is in the league this study extends the model developed by bowman et al 2012 which used point spreads to assess competitive balance in the national football league nfl and the national basketball association nba in this study money lines for the 1999 2011 seasons were used to develop several measures of competitive balance the results indicate that competitive balance increased rather substantially during this period a by product of this research is to identify the most highly rated team and pitcher in 2002 new york yankees were the highest rated team and from the year 2000 pedro martinez was the highest rated pitcher

an overview of afghanistan s trends toward renewable and sustainable energies relentless environmental concerns steep hike in fossil fuel price and increasing demand of non renewable fossil fuels consumption have dramatically increased global search for alternative energies the world requests ever growing energy supplies to sustain economic development and improvement renewable and sustainable energy ever more becoming accepted and established a decisive place in energy system of the word due to ecologicallyresponsiveinsight and a decrease in equipment expenses consistent with its endowment of energy resources each country tried to figure out its own energy portfolio and employing technologies which are economically viable and socially equitable and have minimal adverse impacts this article attempts to review all possible renewable energy sources as a substitute of the current energy profile coal natural gas and petroleum in afghanistan the study found afghanistan power sector as one of the least development sector which its inadequate status is preventing the development of the country as well eventhough the energy is not the only panacea but cost effective energies in abundant quantity and quality on sustainable foundation will help to reach to demand socio economic development the results indicate that afghanistan due to its natural and geographical situations enjoys important prospective for renewable energy bases such as solar wind geothermal and micro hydro power renewable energies could offer the ultimate solution for afghanistan in general and rural areas in actual but switch to altered forms of energy is grounded in multifaceted interations the study indicates number of issues such as great upfront charges absence of providers insufficient funding appliances and feebleindorsed and methodologicalcapability overwhelm and affected the use of renewable energies and technologies in afghanistan however with sufficient investment and practical stages by government andnongovernment agencies and the public encourage these unbound sources could play a vital role not only in afghanistan s energy supply but also in poverty reduction social and political stability and improving living standard

an empirical analysis of energy cost pass through to co2 emission prices abstract we use the nonlinear autoregressive distributed lag nardl model to analyze the asymmetric and nonlinear pass through effects of changes in crude oil prices natural gas prices coal prices and electricity prices on the co 2 emission allowance prices we find that i the crude oil prices have a long run negative and asymmetric effect on the co 2 allowance prices ii the decreases in the coal prices have a stronger impact on the carbon prices in the short run than the increases iii the natural gas prices and electricity prices have a symmetric effect on the carbon prices but this effect is negative for the former and positive for the latter these findings are robust when using both monthly and daily data and when considering bivariate and multivariate models

the clean development mechanism stochastic permit prices and energy investments abstract we analyze the impact on energy investments stemming from different emission permit classes by considering permits that are allocated inside the european emission trading scheme and secondary certified emission reduction scer permits originating from the clean development mechanism one price taking firm which is subject to emission regulation has the choice to invest in gas or wind power plant the firm faces uncertainty regarding stochastically evolving permit prices while it receives a premium on the electricity price for wind energy as a first step we determine the value of the option to invest into a gas power plant over time then we calculate the investment probability of a gas power investment in a range of policy scenarios we find that allowing the usage of scer permits in the present policy framework has a positive impact on gas power investment decoupling the price processes has a similar effect if the quota of scer permits is doubled the decrease in the investment probability for wind power is large we carry out sensitivity tests for different parameter values and find that investment behavior changes significantly with differing interest rates the wind energy premium and volatility

what drives spreads in the euro area government bond market spreads between euro area government bond yields are related to short term interest rates which are in turn related to market liquidity to cyclical conditions and to investors incentives to take risk in theory lower interest rates are associated with lower degrees of risk aversion and smaller government bond spreads empirically the eurosystem s short term interest rates are positively related to those spreads which our econometric model finds to include significant and policy relevant default risk and liquidity risk components simone manganelli and guido wolswijk

price drivers and structural breaks in european carbon prices 2005 2007 this article aims at characterizing the daily price fundamentals of european union allowances euas traded since 2005 as part of the emissions trading scheme ets the presence of two structural changes on april 2006 following the disclosure of 2005 verified emissions and on october 2006 following the european commission announcement of stricter phase ii allocation allows to isolate distinct fundamentals evolving overtime the results extend previous literature by showing that eua spot prices react not only to energy prices with forecast errors but also to unanticipated temperatures changes during colder events besides the sub period decomposition of the pilot phase gives a better grasp of institutional and market events that drive allowance price changes

modeling co2 emission allowance prices and derivatives evidence from the european trading scheme this paper studies the three main markets for emission allowances within the european union emissions trading scheme eu ets powernext nord pool and european climate exchange ecx the analysis suggests that the prohibition of banking of emission allowances between distinct phases of the eu ets has significant implications in terms of futures pricing motivated by these findings we develop an empirically and theoretically valid framework for the pricing and hedging of intra phase and inter phase futures and options on futures respectively

long term association between european and indian markets on carbon credit price abstract this study tries to explore cointegration and granger causality of daily cer prices in european energy exchange and multi commodity exchange mcx in india in a multivariate framework after controlling euro rupee exchange rate and inter bank offer rate a measure of country specific risk both ardl bounds tests and johansen juselius maximum likelihood procedures fail to establish a cointegrating relationship among the variables indicating that an arbitrage opportunity exists between these two markets the study however establishes a short term granger causality running from change in cer price in european energy exchange and exchange rate to indian exchange generalised error variance decomposition of variables indicates that the price of cer at the indian stock exchange is most endogenous in nature

allowance price drivers in the first phase of the eu ets abstract in the first phase of the eu emissions trading scheme eu ets the price per ton of co 2 initially rose to over 30 the price then collapsed to essentially zero by mid 2007 by deriving a structural model of the allowance price under the assumption of efficient markets i examine the extent to which this variation in price can be explained by marginal abatement costs i then gradually relax the model by allowing for delayed adjustment of price to fundamentals as well as by introducing lagged lhs variables the pattern of results suggests that while prices were not initially driven by marginal abatement costs this inefficiency was largely corrected after the accounting of 2005 emissions in april 2006

yield spreads on emu government bonds government bond spreads we provide evidence that the movements in yield differentials between euro zone government bonds explained by changes in international risk factors as measured by banking and corporate risk premiums in the united states are more pronounced for bonds issued by italy and spain liquidity factors play a smaller role so policies meant to increase financial market efficiency do not appear sufficient to deliver a seamless bond market in the euro area the risk of default is a small but important component of yield differentials movements which signal market perceptions of fiscal vulnerability impose market discipline on national fiscal policies and may be reduced only by further convergence in debt ratios lorenzo codogno carlo favero and alessandro missale

voluntary emission trading potential of turkey abstract climate change is likely to cause serious market failures and carbon trading as a market instrument can help correct its negative impacts the global carbon markets established to combat climate change include regulatory and voluntary markets turkey cannot utilise regulatory carbon markets under the kyoto protocol as a result of her unique position in the unfccc some offsetting projects in turkey have benefitted only voluntary emission trading for the reduction of ghg emissions due to on going climate change negotiation under the unfccc it seems that turkey will not use the current regulatory carbon markets thus turkey should promote the use of and participation in voluntary carbon markets in this article emission reduction potential via energy efficiency renewable energy and solid waste management and corresponding offsetting of credits with their estimated prices is investigated for the period between 2013 and 2020 the emission reduction potential for energy efficiency renewable energy and solid waste management projects are estimated at 403 312 and 356 million tons of co 2 equivalent emissions respectively totalling 1 071 million tons of co 2 equivalent the total revenue of the carbon certificates are estimated in the range of 19 775 33 386 million us dollars for the same period

linking with uncertainty the relationship between eu ets pollution permits and kyoto offsets carbon offsets from the kyoto flexible mechanisms can be used by firms in the eu emissions trading scheme for compliance in lieu of eu allowances making these carbon assets interchangeable we offer an explanation of the price spread using a structural model of the price for certified emissions reductions that combines three features a limit for the use of kyoto offsets within the eu ets a disconnect between the current price of offsets and their marginal cost of production for institutional reasons and uncertainty about future supply and demand of offsets our model expresses the offset price as an average of the eu allowance price and an offset s outside value weighted by the probability of a binding import limit using a monthly series of the united nation s clean development mechanism and joint implementation about offset supply and demand we provide empirical support for our theory of offset price formation counterfactual simulations suggest that the price process is dominated by uncertainty

addressing the renewable energy financing gap in africa to promote universal energy access integrated renewable energy financing in malawi abstract the sustainable energy for all initiative is a global initiative launched by the united nations secretary general in 2012 with a goal of providing universal access to modern energy services by 2030 to achieve this goal substantial financial and technological investments will be required at a rate far exceeding historical levels sub saharan africa has a 30 5 electrification rate and policy reform issues to improve electrification have been poorly implemented thereby sprinkling doubt as to whether the region would be able to achieve 100 access to electricity for all by the year 2030 sub saharan africa faces a tough challenge in order to achieve universal access to modern energy services since the region fails to attract energy sector investments there is also a general perception that the region contributes very little to global greenhouse gas emissions hence offers few opportunities to reduce these emissions consequently missing out on attracting climate finance projects a guarantee of power purchase has been shown to attract energy sector investments however guarantees of power purchases such as feed in tariffs are experiencing slow market growth in developing countries because of a range of technical regulatory and financial barriers using malawi as a case study of a developing country this review provides a perspective from a sub saharan africa least developed country as to the various electrification renewable energy deployment and climate change management challenges that still require urgent attention this study shows that despite the perceived regulatory and financial challenges malawi can integrate and use a combination of adapted price guarantee schemes cross subsidies and environmental taxes in order to support initiatives aimed at supporting the country s development of renewable energy sources and hence indirectly support the sustainable energy for all initiative

towards achieving energy for sustainable development in nigeria the importance of energy availability in the economic growth social and political development of every nation cannot be overemphasized affordable and reliable energy availability is the precondition for sustainable development sustainable development calls for an efficient reliable and decentralized energy economy based on local and clean energy sources in which the price paid by the consumer will reflect the real cost of energy products to the economy there is clear evidence that nigeria is blessed with abundant resources of fossil fuels as well as renewable energy resources the major challenge is inefficient utilization of energy in the country there is no doubt that the present power crisis afflicting nigeria will persist unless the government diversifies her energy sources and adopt new available technologies to reduce energy wastages and save cost this study examines the perspective of energy efficiency and renewable energy in the making of strategies for a sustainable development in nigeria such strategies involve energy savings on the demand side efficiency improvements in the energy production and replacement of fossil fuels by various sources of renewable energy factors that need to be considered in the shift to its sustainable energy future are examined in this article

eua and scer phase ii price drivers unveiling the reasons for the existence of the eua scer spread abstract this article studies the price relationships between eu emissions allowances euas valid under the eu emissions trading scheme eu ets and secondary certified emissions reductions scers established from primary cers generated through the kyoto protocol s clean development mechanism cdm given the price differences between euas and scers financial and industrial operators may benefit from arbitrage strategies by buying scers and selling euas i e selling the eua scer spread to cover their compliance position as industrial operators are allowed to use scers towards compliance with their emissions cap within the european system up to 13 4 our central results show that the spread is mainly driven by eua prices and market microstructure variables and less importantly as we would expect by emissions related fundamental drivers this might be justified by the fact that the eu ets remains the greatest source of cer demand to date

time and frequency connectedness among oil shocks electricity and clean energy markets abstract this paper examines the time and frequency connectedness among electricity carbon and clean energy markets and oil price demand and supply shocks in doing so we use the spillover method proposed by diebold and yilmaz 2012 and its extension in the frequency domain by barunik and k ehlik 2018 we find increased connectedness during the global financial crisis as well as in the shale oil revolution period the total connectedness is also higher in the short run compared to the long run due to their low connectedness electricity futures can act as a risk diversifier and safe haven asset against oil shocks net pairwise directional connectedness among oil shocks and the clean energy index is higher during the shale oil revolution these results have important implications for investors with different investment time horizons

modelling the price spread between eua and cer carbon prices abstract this paper identifies factors impacting on the dynamics of the price spread between european allowances euas and certified emission reductions cers by detecting changes in the structural relationship between them while prior studies have assumed a fixed structural relationship this paper analyses the dynamic evolution of the price spread by employing a time varying parameter analysis using daily data from march 2008 to september 2011 the analysis reveals that a lack of competitive conditions in markets access constraints on the use and the availability of cers regulatory changes regarding both euas and cers and uncertainty surrounding cers can explain a significant portion of the price spread

prospective measures of competitive balance application to money lines in the national hockey league the authors have previously introduced the concept of utilizing point spreads to measure competitive balance in professional sports and a methodology for doing so they assessed competitive balance

risk spillovers across the energy and carbon markets and hedging strategies for carbon risk this study examines the risk spillovers between energy futures prices and europe based carbon futures contracts we use a markov regime switching dynamic correlation generalized autoregressive conditional heteroscedasticity ms dcc garch model in order to capture the time variations and structural breaks in the spillovers we further evaluate the optimal weights hedging effectiveness and dynamic hedging strategies for the ms dcc garch model based on both the regime dependent and regime independent optimal hedge ratios we finally complement our analysis by examining the in and out of sample hedging performances for alternative strategies our results mainly show significant volatility and time varying risk transmission from energy markets to carbon market we also find that spot and futures segments of the emission markets exhibit time varying correlations and volatile hedging effectiveness the subsample estimates show significant changes in the hedge effectiveness over the different phases of the european carbon market these results have important investment and policy implications

measuring competitive balance in sports using generalized entropy with an application to english premier league football a central issue in the economics of sport is the degree of competitive balance in sporting contests the importance attached to competitive balance is predicated on the belief that it is uncertainty about the outcomes of sporting contests that attracts spectators and sponsors in a perfectly balanced competition each team would have an equal chance of winning each match and therefore of winning the championship or the league by contrast the absence of competitive balance would mean that the results of sporting contests would become predictable and attendance at sporting contests would suffer the general theme that underpins the issue of competitive balance is that of inequality this article proposes a general measure of competitive balance based on the generalized entropy ge approach to measuring inequality and shows how this might be interpreted in terms of the league s welfare the measures are applied to results from 2006 to 2007 season of the english premier league epl

non universal nature of energy poverty energy services assessment of needs and consumption evidences from rural himachal pradesh abstract consumer behavior in rural ecosystems represents considerable variations vis a vis consumption of energy in different forms consumer preference towards any given energy service is a function of geographical situatedness local customs traditions and tastes including local weather conditions rural flavour of energy poverty has a distinctive micro character which can be understood in terms of socio cultural behaviourism of an energy consumer this geo spatial flavour further appears to be a function of socio economic functionalities of communities which could be socio culturally similar or different energy poverty is saddled with conceptual concentricity empirical evidence shows that the phenomena and the concept both are vulnerable in terms of operationalization by means of a single universal definition it exhibits contrarian hues in terms of availability access distribution affordability and acceptability of an energy service this study presents an alternative approach to understanding of both the phenomena and the associated conceptual construct the present paper is an explicit representation of the everyday grain of energy needs and consumption patterns in six rural socio cultural systems this study based upon fieldwork in the six villages viz bhadroya thapkour and gaghwal kangra district and kakira bidingi and talhara chamba district throws up interesting findings which challenge the contemporary discourse on energy poverty

the vermont common assets trust an institution for sustainable just and efficient resource allocation both private and public sectors have failed to adequately provide critical ecosystem goods and services or an equitable distribution of wealth and income to address this problem the vermont legislature is considering the creation of a vermont common assets trust vcat that would make the state s atmosphere aquifers and other resources created by nature or by society as a whole the common property of all vermonters present and future under the trust a board of trustees would have the legal obligation to manage these assets for the benefit of all vermonters including future generations this paper first explains why certain resources are likely to be managed more sustainably fairly and efficiently as common property than as private property it then discusses mechanisms for integrating assets into the trust estimates of potential revenue from a vcat suggest that it could eliminate the state budget deficit contribute to a better distribution of wealth and resources and help address critical ecological problems survey results suggest that a vcat is politically feasible the vcat promises to be an important pilot project that could later be scaled up to a national or global level

the efficacy of the european union emissions trading scheme depicting the co movement of carbon assets and energy commodities through wavelet decomposition abstract environmental system thresholds have been crossed for a number of dimensions of global environmental pollution such as greenhouse gas emissions under this scenario institutions and corporations are required to implement sustainable policies as a condition for humanity staying within planetary boundaries accordingly the european union created the largest emissions trading scheme in the world with the aim of properly managing corporations carbon dioxide reductions this paper aims to contribute to the literature focused on testing the effectiveness of institutional environmental management policies specifically this research evaluates whether the objectives of the european union emissions trading scheme are partially achieved by analyzing the dynamics of carbon assets and the main energy commodities worldwide this paper provides relevant information both for policy makers and company managers so that contributions towards the common goal of developing a clean energy future and curbing climate change are ameliorated based on wavelet coherence analysis this paper proposes a model free way of estimating the time varying correlations between carbon assets and energy commodities at both high and low frequencies our central results reveal that carbon assets and energy commodities present a changing lead lag behavior at different frequencies the energy commodities lead the european union allowances returns at medium frequencies but the contrary was true for the highest investment horizons this finding should be in line with the goal of significantly reducing emissions because during long cycles if the majority of companies have not switched to cleaner industrial processes they must buy more carbon assets increasing their prices in that case energy commodities would be more expensive because of the energy commodities market behavior during long term horizons with european union allowances lead the certified emissions reductions lead in a negative way most of the energy commodities at medium frequencies thus indicating that investors handling energy commodities oriented portfolios could incorporate the mentioned carbon assets for diversification purposes these specific findings suggest that polluting activities would be more expensive which would provide an incentive to companies to implement environmentally friendly industrial processes the european union emissions trading scheme can result in significant emission reductions and compliance of the european union with the objectives of the kyoto protocol

least cost network evaluation of centralized and decentralized contributions to global electrification abstract the choice between centralized and decentralized electricity generation is examined for 150 countries as a function of population distribution electricity consumption transmission cost and the cost difference between decentralized and centralized electricity generation a network algorithm is developed to find the shortest centralized transmission network that spans a given fraction of the population in a country the least cost combination of centralized and decentralized electricity that serves the country is determined case studies of botswana uganda and bangladesh illustrate situations that are more and less suited for decentralized electrification specific maps for centralized and decentralized generation are presented to show how the least cost option varies with the relative costs of centralized and decentralized generation and transmission cost centralized and decentralized fractions are calculated for 150 countries for most of the world s population centralized electricity is the least cost option for a number of countries particularly in africa substantial populations and regions may be most cost effectively served by decentralized electricity

the impact of the european union emission trading scheme on electricity generation sectors in order to comply with their commitments under the kyoto protocol france and germany participate to the european union emission trading scheme eu ets which concerns predominantly electricity generation sectors in this paper we seek to know if the eu ets gives appropriate economic incentives for an e cient and strong system in line with kyoto commitments because if so electricity producers in these countries should include the price of carbon in their costs functions after identifying the di erent sub periods of the eu ets during its pilot phase 2005 2007 we model the prices of various electricity contracts and look at their volatilities around their fundamentals while evaluating the correlation between the electricity prices in the two countries we finnd that electricity producers in both countries were constrained to include the carbon price in their cost functions during the rst two years of operation of the eu ets during this period german electricity producers were more constrained than their french counterparts and the inclusion of the carbon price in the cost function of electricity generation has been so much more stable in germany than in france furthermore the european market for emission allowances has increased the market power of the historical french electricity producer and has greatly contributed to the partial alignment of the wholesale price of electricity in france with those of germany

sterling s relationship with the dollar and the deutschemark 1976 89 this paper evaluates the linkages between bilateral exchange rates using a time varying parameter model which can be estimated using the kalman filter the technique solves many of the statistical problems which arise when ordinary least squares is used to estimate currency correlation applying the technique to the dollar sterling dm sterling and dm dollar bilateral exchange rates the results suggest a market weakening strengthening of sterling s relationship with the dollar dm since the mid 1970s additionally these currency linkages are shown to have undergone a number of regime shifts suggesting that the timing of the weakening of the dollar sterling relationship is different to that proposed by previous studies copyright 1991 by royal economic society

rural electrification in zambia a policy and institutional analysis abstract zambia is well endowed with hydropower and other energy resources which could facilitate production of electricity for both urban and rural areas of the country the country has an installed electricity generation capacity of 1786 mw and undeveloped hydropower potential of over 6000 mw in the last few years demand has been growing and it is anticipated to outstrip supply in 2008 the load growth is attributed to increased mining activities and development of the industrial base the country is also endowed with abundant natural resources such as arable land water minerals and wildlife with the available resource base electricity along with other social and economic infrastructure such as roads and telecommunications could facilitate increased economic activities in rural areas electricity could be used for crop irrigation agro processing small scale mining and to facilitate tourism however rural electrification re faces many challenges such as long distances from existing power stations to targeted rural areas low population densities high poverty levels and low skills availability these and other factors have contributed to continued low levels of access to electricity in rural areas of the country measures so far undertaken to facilitate access to electricity in rural areas of zambia include the adoption of a new national energy policy nep in 1994 with regard to the electricity sector and re in particular the nep was aimed at facilitating increased access by liberalising and restructuring the electricity market and promoting the use of low cost technologies and decentralised renewable energies to facilitate implementation of the new policy the government established a legal and institutional framework by enacting new legislation namely the electricity act and the energy regulation act in 1995 the electricity act provided for liberalisation and regulation of the electricity sector while the energy regulation act provided for the establishment of an independent regulator so as to stimulate private sector participation and efficiency in addition a rural electrification fund ref and associated administration mechanism was established in 1995 however re continued to experience many challenges in 2003 the government enacted the rural electrification act leading to the establishment of an agency dedicated to re this paper analyses the policy legal and institutional measures implemented in zambia and assesses their potential or effectiveness to tackle some of the challenges facing re in the country so as to increase access and affordability

research and development aspects on decentralized electrification options for rural household abstract low income households living in the rural areas suffer from energy poverty and lack of human and economic development currently many governments of less developed countries are committed in improving access to electricity the same commitment should be adapted globally as part of human right because providing electricity access to low income households improves health and education generates income increases productivity reduces inequality and enhances the quality of life rural electrification is a complicated issue because of user affordability rural inaccessibility and remoteness low population densities and dispersed households low project profitability fiscal deficit scarcity of energy resources population growth lack of professionalism and over dependence on subsidies the demand for electrification cannot be accomplished because of the increasing gap between rural electrification rate and population growth therefore this review aims to study various decentralized household sized energy technologies available in rural areas such as battery diesel generator pedal generator pico hydro photovoltaic pv solar home system and wind preference for one of the options depends on energy source availability economic feasibility rural economic development disposal of residues nature of end user application and government programs and policies pico hydro is the preferred electricity generation source in most rural households followed by wind pv and diesel generators this paper concurs that households in rural areas will be able to afford for electricity access if the payment schedule of the electrification cost is extended and interest rates and taxes if any are dropped
