A fact sheet overview of the activities of the Office of Energy Efficiency.

This comment aims at critically analyzing some of the economic efficiency issues that are raised in the paper by Muñoz et al. [2007. Harmonization of renewable electricity feed-in laws in the European Union. Energy Policy 35, 3104-3114] on the harmonization of feed-in law schemes for renewable electricity in the European Union. We comment on the choice between green certificate systems and feed-in laws, but pay particular attention to the implementation and design of a harmonized feed-in law scheme. In the comment we argue first that the approach suggested by Muñoz et al. tends to downplay many of the practical difficulties in assessing the real costs facing investors in renewable electricity, not the least since the presence of regulatory uncertainty about the marginal costs of renewable electricity may be essential for the choice between different support systems. Concerning the benefit side of renewable electricity promotion, the Muñoz et al. (2007) paper builds on an interpretation of the EU Renewables Directive that provides plenty of room for national priorities and that therefore essentially implies that harmonized support premiums per se are of little value. We argue instead that a harmonized system should primarily address the international spillover effects from renewable electricity promotion, not the least those related to improved security of supply in Europe. There exists then a strong case for disregarding the specific national benefits of renewable electricity production in the design of harmonized support systems, and for instead considering international-perhaps at the start bilateral-policy support coordination based on entirely uniform support levels. ; Validerad; 2008; 20080211 (patrik_s)

The twenty-first century must see a decarbonisation of electricity production to mitigate the flow of greenhouse gas emissions into the atmosphere. This paper presents an econometric analysis of the factors that motivate the use of renewable energy in electricity production using panel data from EU Member States during the period 2000-2015. The research extends the literature in this area in several ways. Firstly, the econometric analysis is focused on the electricity sector rather than on the overall primary energy supply, which also includes the diverse heating and transport sectors. In addition, an alternative public policy variable is proposed using the tax and levy component of electricity bills. Furthermore, an alternative econometric approach is employed using a hybrid mixed effects estimator. The results of this analysis are found to be broadly as expected, with mixed fossil fuel price effects; electricity grid interconnection and higher levels of greenhouse gas emissions both motivate the development of renewable electricity. Policy implications are that policy support for fossil fuels should be ceased; electricity grid interconnections should be developed between countries; and furthermore, levies on retail electricity prices to fund RE support schemes are effective at promoting renewable electricity.

The EU's power sector is in the middle of a monumental shift from fossil-fuel to renewable generation.

Despite considerable mitigation efforts, global emissions from the electricity sector continued to grow in recent years. In Australia, the electricity sector is the largest CO2-emitting industry, contributing 35% of the country's total greenhouse gas emissions. The Australian government targets an 80% reduction of greenhouse gas emissions by 2050 relative to 2010. With a large variety and quantity of renewable energy resources, it is technically feasible and seems indispensable that Australia's electricity sector be largely decarbonised by 2050 in order to achieve this target. In this paper, scenario-based hybrid Life-Cycle Assessment is applied to calculate the economy-wide carbon footprints of seven electricity generation technologies in scenarios with differing renewable electricity penetration. This work is the first to apply a full life-cycle approach to scenario analysis of electricity generation in Australia. The findings are at the higher end of previously reported carbon footprint intensity ranges and above median values. However, even when taking into account indirect emissions along the technologies' life-cycles, the results indicate that the employment of different renewable energy technologies can potentially save a considerable fraction of Australia's greenhouse gas emissions. This makes renewables an essential option for climate change mitigation.

"This book investigates the role of law in enabling and addressing the barriers to the development of Off-Grid Renewable Electricity (OGRE). The limited development of OGRE is ascribed to a host of social, economic and legal barriers including the problem of initial capital costs, existing subsidies for conventional electricity and lack of technological and institutional capacity. Through the analyses of selected case studies from Africa, Asia, Europe, North and South America, this book discusses the typical barriers to the development of OGRE from a global perspective and examines the role of the international climate change instruments in addressing them. Drawing together the lessons learned from the case studies, the book offers robust recommendations on how the development of OGRE will support the goal of achieving universal access to low carbon, reliable and sustainable electricity globally. This volume will be of great interest to students, scholars, policy makers, investors and practitioners in the fields of energy law and policy, climate change, and renewable energy development"--
