In order to meet its 2050 target of 80% carbon emissions reduction, the UK is facing a challenge of restructuring its energy system, possibly by introducing more decentralised energy (DE) systems.Following semi-structured interviews, four exemplar international cases have been critiqued in order to investigate the variety and interrelationship of the drivers and barriers involved during their implementation, and then compared with the barriers and drivers that can potentially affect the implementation of similar projects in the UK context. The impacts of the barriers on the outcomes of these projects were evaluated, and recommendations were presented on overcoming these barriers if replicating similar projects in the UK context. Governance drivers play the most significant role, whereas financial drivers (commonly believed to be crucial), are deemed to play a lesser role. Social, governance and financial barriers rather than technological barriers constitute the central problem areas for the increased adoption of DE. The drivers and barriers experienced in the international cases were similar to those anticipated in the UK. The case studies present a high potential for replication and scaling up in the UK context and demonstrate that the increased implementation of DE systems could also enhance social and governance benefits.

| Summary/Abstract |
This paper introduces a new agent-based model, which incorporates the actions of individual homeowners in a long-term domestic stock model, and details how it was applied in energy policy analysis. The results indicate that current policies are likely to fall significantly short of the 80% target and suggest that current subsidy levels need re-examining. In the model, current subsidy levels appear to offer too much support to some technologies, which in turn leads to the suppression of other technologies that have a greater energy saving potential. The model can be used by policy makers to develop further scenarios to find alternative, more effective, sets of policy measures. The model is currently limited to the owner-occupied stock in England, although it can be expanded, subject to the availability of data.

| Summary/Abstract |
Gujarat, a large industrialized state in India, consumed 67 TWh of electricity in 2009-10, besides experiencing a 4.5% demand-supply short-fall. Residential sector accounted for 15% of the total electricity consumption. We conducted load research survey across 21 cities and towns of the state to estimate residential electricity load curves, share of appliances by type and usage patterns for all types of household appliances at utility, geographic, appliance, income and end-use levels. The results indicate that a large scope exists for penetration of energy efficient devices in residential sector. Marginal Abatement Cost (MAC) curves for electricity and CO2 were generated to analyze relative attractiveness of energy efficient appliance options. Results indicate that up to 7.9 TWh of electricity can be saved per year with 6.7 Mt-CO2 emissions mitigation at negative or very low CO2 prices of US$ 10/t-CO2. Despite such options existing, their penetration is not realized due to myriad barriers such as financial, institutional or awareness and therefore cannot be taken as baseline options for CO2 emission mitigation regimes.

| Summary/Abstract |
Maximizing renewables in the country's power system has been a key political agenda in Japan after the Fukushima nuclear disaster. This paper investigates the potential of PV resource, which could be systematically integrated into the Japanese power system, using a high time-resolution optimal power generation mix model. The model allows us to explicitly consider actual PV and wind output variability in 10-min time resolution for 365 days. Simulation results show that, as PV expands, the growth of PV integration into the grid slows down when the installed PV capacity is more than the scale of the peak demand, although Japan has immense potential of installable PV capacity - equivalent to 40 times of the peak. Secondly, the results imply that a large-scale PV integration potentially decreases the usage ratio of LNG combined cycle (LNGCC) in specific seasons, which is a challenge for utility companies to ensure that LNGCC is used as a profitable compensating generator for PV variability. Finally, a sensitivity analysis on rechargeable battery cost suggests that the reason for suppressing the PV output instead of storing its surplus output by the battery can be attributed to the high battery cost; hence, the improvement of its economic performance is significant to integrate the massive PV energy.

| Summary/Abstract |
The 2009 Renewable Energies Directive (RED) has set up ambitious targets concerning biofuel consumption in the European Union by 2020. Nevertheless, budgetary constraints and growing concerns about the environmental integrity of first-generation biofuels have imposed a phasing out of the fiscal instruments to promote them. Focusing on France, this paper combines an exogenous increase in oil prices and tax policies on fossil fuels. The objective is to determine the efficiency of an alternative incentive scheme for biodiesel consumption based on a higher price of the fossil fuel substitute. Policy simulations are implemented through a dynamic computable general equilibrium (CGE) model calibrated on 2009 French data. The results show that the 10% biodiesel mandate set by the RED would not be achieved even if the fixed taxes on diesel reach the same level as those on gasoline. Although integrating the rise in oil prices into the fiscal framework improves the biodiesel penetration rate, it remains below the target. Moreover, we find that the effects of biofuel consumption are limited to the biofuel chain sectors. In other agricultural sectors, the substitution effect of biodiesel with diesel is partially offset by the pricing effect induced by higher energy production costs.

| Summary/Abstract |
As the President of the Office of Competition and Consumer Protection refused to approve a government initiated takeover in the Polish power sector and the Court of Competition and Consumer Protection did not make a ruling on that case, the takeover was finally prohibited. In this context, the main aim of this paper is to carry out a quantitative analysis of the impact of the takeover in question on electricity prices and quantities, consumer and producer surpluses, dead weight loss and emissions. The scope of the study covers the Polish power generation sector and the analysis was carried out for 2009. A game theory-based electricity market equilibrium model developed for Poland was applied. The model includes several country-specific conditions, such as a coal-based power generation fuel-mix, a large share of biomass co-combustion, etc. For the sake of clarity, only four scenarios are assumed. The paper concludes that the declared synergy savings did not compensate for the increase in dead weight loss and the transfer of surplus from consumers to producers caused by increased market power.

| Summary/Abstract |
Wind energy has been negotiated in Brazil's regulated market through auctions organized by the government. Bilateral negotiations in the free market have been scarce. In 2011 wind farms were allowed to bid in 'A minus 5 (A?5)' auctions, for energy with first delivery date 5 years ahead. This new design was expected to stimulate negotiations in the free market, as the 20-year contract in the regulated market eases financing while the 5-year grace period grants wind farms the option to sell whatever energy is generated beforehand in the free market. We modeled bidders' price decision in A?5 auctions as Real Options and concluded that given the low prices averaging USD 50/MW h, winners are tempted to defer investment, expecting more favorable equipment and energy prices, or a better knowledge of the wind site. Construction is likely to begin in 2-3 years, with little time left for the free market. Bidders that consider the option of eventually abandoning the project are more price competitive, increasing chances that some wind farms will never materialize. Therefore, this attempt to foster the free market may not pay-off and, moreover, it may have the unfavorable effect of turning Brazil's energy expansion planning a more difficult task.

| Summary/Abstract |
In the last few years, rare earth materials (REM) prices have experienced a strong increase due to geopolitical and sustainability issues. Financial markets could already have factored in concerns about shortages of REM supplies into clean energy companies' valuations. We use a multifactor market model for the period January 2006 to September 2012 to analyze the impact of REM price trends - specifically dysprosium and neodymium - on six clean energy indices (NYSE-BNEF) tracking the world's most important companies in the clean energy sector. The results show that during period of price increase, there is a negative relationships between REM price changes and the stock market performance of some clean energy indices. The European clean energy index is also negatively affected, and this effect could be relevant to policy makers, considering that Europe is implementing some relevant policy actions to support the development of the clean energy industry.

| Summary/Abstract |
The Fukushima disaster has lead the French government to release novel cost information relative to its nuclear electricity program allowing us to compute a levelized cost. We identify a modest escalation of capital cost and a larger than expected operational cost. Under the best scenario, the cost of French nuclear power over the last four decades is View the MathML source (at 2010 prices) while in the worst case it is View the MathML source. On the basis of these findings, we estimate the future cost of nuclear power in France to be at least View the MathML source and possibly View the MathML source. A comparison with the US confirms that French nuclear electricity nevertheless remains cheaper. Comparisons with coal, natural gas and wind power are carried out to find the advantage of these.

The number of multi-family housing complexes (MFHCs) over 15 yr old in South Korea is expected to exceed 5 million by 2015. Accordingly, the demand for energy retrofit in the deteriorating MFHCs is rapidly increasing. This study aimed to develop a decision support model for establishing the optimal energy retrofit strategy for existing MFHCs. It can provide clear criteria for establishing the carbon emissions reduction target (CERT) and allow efficient budget allocation for conducting the energy retrofit. The CERT for "S" MFHC, one of MFHCs located in Seoul, as a case study, was set at 23.0% (electricity) and 27.9% (gas energy). In the economic and environmental assessment, it was determined that scenario #12 was the optimal scenario (ranked second with regard to NPV40 (net present value at year 40) and third with regard to SIR40 (saving to investment ratio at year 40). The proposed model could be useful for owners, construction managers, or policymakers in charge of establishing energy retrofit strategy for existing MFHCs. It could allow contractors in a competitive bidding process to rationally establish the CERT and select the optimal energy retrofit strategy. It can be also applied to any other country or sector in a global environment.

| Summary/Abstract |
This paper analyzes the distributional implications of an illustrative $15 carbon tax imposed in 2010 on carbon in fossil fuels. We analyze its incidence across income classes and regions, both in isolation and when combined with measures that apply the carbon tax revenue to lowering other distortionary taxes in the economy. Consistent with earlier findings, we find that a carbon tax is regressive. Using tax swap simulations, we then subtract the burden of other taxes the carbon tax revenue could displace, and compute the net effect on households under three assumptions about how capital and labor income might be distributed.

| Summary/Abstract |
Data envelopment analysis (DEA) has gained much popularity in performance measurement of power industry. This paper presents a slack-based measure approach to investigating the relationship between fossil fuel consumption and the environmental regulation of China's thermal power generation. We first calculate the total-factor energy efficiency without considering environmental constraints. An environmental performance indicator is proposed through decomposing the total-factor energy efficiency. The proposed approach is then employed to examine whether environmental regulation affects the energy efficiency of China's thermal power generation. We find that the environmental efficiency plays a significant role in affecting energy performance of China's thermal generation sector. Decreasing the discharge of major pollutants can improve both energy performance and environmental efficiency. Besides, we also have three main findings: (1) The energy efficiency and environmental efficiency were relatively low. (2) The energy and environmental efficiency scores show great variations among provinces. (3) Both energy efficiency and environmental efficiency are of obvious geographical characteristics. According to our findings, we suggest some policy implications.

| Summary/Abstract |
This study attemps to investiagte the causal relationship between oil consumption and economic growth in Malaysia where oil consumption and real gross domestic product have been rapidly increased in recent years. To this end, the study employs annual data covering the period 1965-2011. Tests for unit roots, co-integration, and Granger-causality based on the error-correction models are presented. The overall results support the existence of bi-directional causality between oil consumption and economic growth in Malaysia. This means that an increase in oil consumption directly affect economic growth. Thus, in order not to make an adverse effect on economic growth, Malaysia should endeavor to overcome the constraints on oil consumption. Moreover, it appears that economic growth induces oil consumption

| Summary/Abstract |
Commuting is one of the main contributors to the high energy consumption patterns in modern economies. The need to reduce the energy spent in commuting has attracted the attention of academics and policy makers. The main goal of this research is to improve knowledge of the economic, social, energy and environmental opportunity costs of inter-municipality commuting and to support policy-oriented strategies that explicitly take them into account. For this, we use hypothetical assumptions based on the baseline scenario that Portuguese households do not travel between municipalities for commuting purposes coupled with the expected changes in private final consumption. Accordingly, the direct, indirect and induced opportunity costs of inter-municipality commuting are assessed using an input-output model. The significance of the estimated virtual net benefits of commuting is analyzed according to their macroeconomic (GVA, taxes, international imports and employment), energy (primary energy consumption) and environmental (CO2 emissions) dimensions. The results obtained empirically indicate that inter-municipality commuting has significant opportunity costs in the GVA and GDP as well as in primary energy consumption and CO2 emissions. The results also indicate that commuters in metropolitan regions and long-distance commuters are responsible for a major share of these opportunity costs.

| Summary/Abstract |
Sustainability is fundamentally a challenge of tradeoffs. In order to improve human well-being through economic development we consume nonrenewable energy and other natural resources, relying on a broad range of ecosystem services. Enhancing sustainability requires reducing the "energy intensity of human well-being (EIWB)": the amount of energy used per unit of human well-being. In this study we employ longitudinal analysis techniques to assess the temporally dynamic relationship between EIWB and economic development for a sample of 12 Central and Eastern European (CEE) nations for the 1992 to 2010 period. These are nations that have recently transitioned, which is still an ongoing process, from socialist command economies to market demand economies. During this ongoing transition, many of them have experienced declines in energy intensity, coupled with increased energy efficiency, while human well-being has improved considerably. The results of the analysis indicate that the relationship between EIWB and economic growth in CEE nations is complex and has changed dramatically through time. Of particular importance, the later years of the study exhibit an increasingly sustainable relationship between EIWB and economic development. The findings point to future possibilities for relatively more harmonious relationships between development, human well-being, and the natural environment.

Transportation contributes to resource depletion and has other negative impacts on the environment. The present study presents models of energy demand and environmental emissions for the land transportation sector in Metro Manila, Philippines from 2010 to 2040 using the "Long Range Energy Alternatives Planning (LEAP)" tool. The study projected energy demand and CO2, CO, HC, NOx and PM10 emissions for Business-As-Usual (BAU) and alternative scenarios and compared the results while aiming to determine optimal transportation policies to reduce energy demand and emissions. The results indicated that the adoption of EURO 4 emission standards provides the greatest reduction in energy use at 10.8%, while the best cases for the various gas emissions were split among different options. In addition, a combination of all of the alternatives is expected to lower energy use by 27.8% and to reduce CO2, CO, HC, NOx and PM10 by 30.3%, 60.3%, 59.0%, 48.2% and 66.4%, respectively. The analytical framework employed herein could be applied to other cities to evaluate and prioritize strategies to reduce future energy requirements and emissions.

| Summary/Abstract |
Measuring energy efficiency is crucial when planning energy reduction policies. However, decision makers are understandably reluctant to act in the absence of solid data and results supporting a policy position. This paper proposes a methodology to measure the energy efficiency of farms based on the Data Envelopment Analysis (DEA) approach. In a manner similar to the cost framework, we decompose energy efficiency measurements into technical and allocative efficiencies in energy contents of inputs. In this study, we replace input prices used in traditional economic efficiency measurements by their energy content. We use the energy efficiency model to explore the optimal input-mix that produces the current outputs at minimum energy-consumption. We demonstrate that this decomposition can help policy makers design accurate energy policies. However, the uncertainty of the data and, more particularly, the energy content of the inputs leads us to recommend using the methodologies to calculate the bounds of efficiency to obtain more plausible and robust results. Based on our analysis, energy efficiency is not a fixed value, and policy-makers should consider it with caution. We use a 2007 database of French farms specialised in field crops for empirical illustration.

| Summary/Abstract |
In low- and middle-income countries, Liquefied Petroleum Gas (LPG) can be an attractive alternative to the widespread use of traditional kerosene. Not only is LPG a relatively clean, safe and cost-effective fuel for households, its large-scale adoption also reduces the heavy burden of kerosene consumption subsidies on government budgets. Against this background, we evaluate the impact of a large government program to substitute LPG for kerosene in Indonesia. Using a household survey across urban, suburban and rural regions we find that this program was very effective in causing a large scale shift from kerosene to LPG. This shift was positively influenced by level of education, household size and household income. Contradicting the energy-ladder model, the LPG program, reinforced by an increase in the price of kerosene, led to increased stacking of fuels, including increasing consumption of both electricity and traditional biomass. In addition, our analysis shows that the LPG program failed to substantially reduce the overall number of energy-poor people, but it has been effective in alleviating extreme energy-poverty. Finally, we find that medium and higher income households in suburban areas benefitted most from the LPG program.

| Summary/Abstract |
To cope with the excessive growth of energy consumption, the Chinese government has been trying to strengthen the energy regulation system by introducing new initiatives that aim at controlling the total amount of energy consumption. A partial frontier analysis is performed in this paper to make a comparative assessment of the combinations of possible energy conservation objectives, new constraints and regulation strategies. According to the characteristics of the coordination of existing regulation structure and the optimality of regulation strategy, four scenarios are constructed and regional responsibilities are reasonably divided by fully considering the production technology in the economy. The relative importance of output objectives and the total amount controlling is compared and the impacts on the regional economy caused by the changes of regulation strategy are also evaluated for updating regulation policy.
