The latest report from the Intergovernmental Panel on Climate Change urges that global CO 2 emissions from the power sector should be reduced by 90 percent or more below 2010 levels between 2040 and 2070. Such a reduction will most likely require greatly increasing the share of wind, solar, energy storage and nuclear energy in the energy mix in the next 40–50 years. This paper emphasizes the importance of developing large energy storage systems without which, wind and solar can only have a limited impact on CO 2 emissions as it will depend mainly on the energy mix used during wind and solar down time. The large areas that are required would be challenging, but not unrealistic, as long as a solution for energy storage exists. Carbon capture and storage has considerable potential to reduce CO 2 emissions from coal and gas power plants, but also from heavy industries such as cement and steel manufacturing. To give an idea of the scale of the required infrastructure, in the United States, coal and gas power plants emit approximately 2.4 billion tonnes of CO 2 per year; whereas the US annual petroleum consumption is about 0.9 billion tonnes (6.9 billion barrels). This paper also emphasizes that uranium and thorium used in breeder reactors represent an almost infinite source of low-carbon energy. The issues associated with the management of nuclear wastes are real, but they are not the uniquely difficult issues perceived by the media, much of the public and by many politicians. Finally, the investment necessary to implement a wind and solar powered economy would very likely be higher than that necessary to implement a nuclear powered economy because of the much larger number of GWe required.

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.

Energy planning can be defined as a roadmap for meeting the energy needs of a nation and is accomplished by considering multiple factors such as technology, economy, environment, and the society that impact the national energy issues. Long-term energy planning is a strategic approach to study how structural changes of a nation would affect the energy demand and supply. This is done through scenario analysis which would also cater for uncertainty in planning. Good energy plan would ensure sustainable development which acts as a guiding factor for any energy scheme. In this paper, we present an overview of the different facets of energy planning based on a comprehensive literature review. It present the risks, uncertainties and errors involved in energy planning. The econometric, optimization and simulation models are reviewed and five appropriate computer models, that can be used for a small developing island nation׳s long-term energy planning using scenario analysis, are discussed. This paper also discusses the inquiry method and elaborates on why it can be used for energy planning in small developing island countries. Validation process of energy models is also presented and finally, recommendations are made for energy planners. [ABSTRACT FROM AUTHOR]

At present, there is no specific legal basis for the development and utilisation of marine renewable energy, nor legal protection for the developers in China. The consequence is that the Chinese Government is unable to provide institutional support for the substantive development of marine renewable energy, resulting in slow development of China's marine energy industry. This paper provides an institutional framework for the establishment of relevant laws in China and legislative proposals in legal perspective, for the better development of marine renewable energy. The Chinese Government should optimise the administrative management system, strengthen financial regulation such as tax and emphasise sustainable development. [ABSTRACT FROM AUTHOR]

Abstract: There is a growing consensus that universalization of modern energy services is central to reducing major elements of poverty and hunger, to increase literacy and education, and to improve health care, employment opportunities, and lives of women and children. In India, as per 2011 census, over 700 million people lack access to modern energy services for lighting, cooking, water pumping and other productive purposes. Devoid of these services people, mostly women, are forced to spend significant amounts of their time and effort on subsistence activities like firewood collection, carrying these head load for miles, and then burning these hard earned fuels inefficiently in traditional chullas. These adversely affect the health and standard of living for women and act as a barrier to gender development (here ‘gender’ means women unless otherwise specified). Although the links between gender inequity, poverty, and energy deprivation have been studied by many, not many practical solutions to the above problems have emerged. The present paper explores the nexus among gender–energy–poverty, highlights areas of gender concern, and suggests actions. We analyze how women from rural areas and low income households are at the receiving ends of energy poverty. We then analyze the roles women as an important stakeholders in universalizing modern energy services. We show how women self-help groups can be a vital link in large-scale diffusion of energy-efficient and renewable technologies. The paper concludes with policy pointers for sustainable development and gender empowerment through energy solutions. [Copyright &y& Elsevier]
