Electricity is certainly the noblest form of energy that humanity has learned to create, control, and use. Its production represents an important economic activity, as well as the most important factor for the socio-economic development of a country, while production capacities, i.e., the largest production capacity, the company JSC "ESM", represents the most important segment of the power system. Accordingly, the issue that has been elaborated on is very actual because it addresses the capital projects of JSC "ESM", which are of great economic and environmental importance. After all, investing in growing electricity production, especially from renewable energy sources, has a large impact on the economic development of the country as a whole, as well as on environmental protection. In this context, the analysis in this paper is mainly focused and aims to address the importance and impact of the construction of the capital projects of JSC "ESM" in the development strategy and the creation of sustainable company competitiveness. Therefore, JSC "ESM" as a serious company, should strive and make a great contribution to the implementation of capital projects, due to the great impact, and to be the most important and leading factor in the liberalized market, especially in times of energy crisis in the country and beyond. For this purpose, the data that are carefully selected and processed, form the basic thesis for the specificity, importance, and actuality of the capital projects for the development and competitiveness of the company.

Summary: The rapid development of China's economy cannot be separated from the massive consumption of fossil fuel. However, potential risks such as the extreme shortage of fossil fuel and the resulting environmental problems are becoming more and more prominent. As a substitution for fossil fuel, renewable energy is playing an increasingly important role in the energy structure adjustment. As a special type of renewable energy, marine renewable energy has been paid much attention by China's government and scientific researchers because of its properties such as cleanness, environmental protection and large reserves. Under the background of energy structure adjustment and electricity market reform in China, the marine renewable energy power market has a bright future. Through querying an amount of literature and information, this paper makes a strategic analysis based on the understanding of the resource endowment, the current industrial status, and policy environment. Then, the PEST‐SWOT strategy analysis model was adopted to analyze the internalities (strengths and weaknesses) and the externalities (opportunities and threats) of the factors affecting the development of marine renewable energy power industry. Then, some countermeasures from the four angles of strategic positioning, institutional arrangement, environmental education, and technical support are proposed to address the weaknesses and threats. Through the research, some conclusions and policy proposals are finally put forward to promote the sustainable development of the industry. In this paper, current situation of China's marine renewable energy reserves is investigated. The PEST‐SWOT strategy analysis model is adopted to analyze the internalities (strengths and weaknesses) and the externalities (opportunities and threats) of the factors affecting the development of marine energy power industry. And the corresponding countermeasures and policy suggestions on promoting the sustainable development of the industry are proposed. [ABSTRACT FROM AUTHOR]

Abstract: This paper analyzed the interactions among China’s economic growth and its energy consumption, air emissions and air environmental protection investment during 2000–2007. Conventional energy and emergy are applied to quantify energy consumption and emissions’ impact, respectively. The five indicators based on money, energy and emergy, including ratio of nonrenewable energy to renewable energy (RNR), energy use per unit GDP (EUPG), environmental cost per unit GDP (ECPG), impact of emissions per unit energy consumption (IEPEC), and environmental benefit per unit environmental protection investment (EBPEI), are presented to depict the relationships among economic growth and energy consumption and impact of air emissions and air environmental protection investment. The results show that energy consumption rapidly rises with China’s fast economic growth; however, energy efficiency and environmental loading intensity from energy consumption are reduced simultaneously but their improvements fall far behind economic growth rate. Impact of air emissions, mainly composed of impact of emissions on human health (especially dust), is slightly decreased. The performance of air environmental protection investment is obviously declined in the study period. Generally speaking, the conflict among economy, energy and air environment protection is slightly mitigated but still acute due to great dependence of China’s economy on fossil energy and inefficient environmental protection measures. Finally, this paper discusses the corresponding issues, and then puts forward some related suggestions. [Copyright &y& Elsevier]

Abstract: Since Taiwan imports more than 99% of energy supply from foreign countries, energy security has always been the first priority for government to formulate energy policy. The development of renewable energy not only contributes to the independence of energy supply, but also achieves benefits of economic development and environmental protection. Based upon information available to public, the present paper reassesses reserves of various renewable energies in Taiwan. The assessment includes seven kinds of renewable energies, namely, solar energy, wind power, biomass energy, wave energy, tidal energy, geothermal energy and hydropower, which are all commercialized and matured in terms of current technologies. Other renewable energies, which have not proven as matured as the aforementioned ones, are only assessed preliminarily in this paper, such as second generation of biomass, deep geothermal energy, the Kuroshio power generation and ocean thermal energy conversion. According to the estimation of this paper, the reserve of wind energy, up to 29.9kWh/d/p (i.e., kWh per day per person), is the largest one among seven kinds of renewable energies in Taiwan, followed by 24.27kWh/d/p of solar energy, 4.55kWh/d/p of biomass, 4.58kWh/d/p of ocean energy, 0.67kWh/d/p of geothermal energy and 16.79kWh/d/p of hydropower. If regarding biomass as a primary energy, and assuming 40% being the average efficiency to convert primary energy into electricity, the total power of the seven kinds of renewable energy reserves is about 78.03kWh/d/p, which is equal to 2.75 times of 28.35kWh/d/p of national power generation in 2008. If the reserves of 54.93kWh/d/p estimated from other four kinds of renewable energies that have not technically matured yet are also taken into account, it will result that the reserves of renewable energy in Taiwan can be quite abundant. Although the results of the assessment point out that Taiwan has abundant renewable energy resources, the four inherent shortcomings – low energy density, high cost of power generation, instability of power supply, and current cost of renewable energy being still higher than that of fossil energy – have to be overcome first, before renewable energy is actually formed as a main component in national energy mix. The measures executed by government to break through these barriers further include the upgrade of the technological level, the formulation of the necessary policies, and the work together from all levels for the overall promotion.

Performance reliability advances and cost reductions have been achieved with hydrogen and fuel cell technologies in both the transportation and distributed energy sectors. This paper reviews the status of hydrogen and fuel cell technologies, identifies key business and policy drivers for the hydrogen economy, critically examines key barriers to implementing the hydrogen economy, identifies and discusses key national initiatives to advance the hydrogen economy, and identifies and discusses key intergovernmental initiatives and activities to advance the hydrogen economy. Hydrogen and fuel cell technology advances, coupled with a reduction in costs and improvements in performance reliability, present new opportunities for developed and developing countries to achieve energy, economic and environmental security. Substantial national research and development investments in hydrogen production, storage, transport, end-use technologies (e.g., fuel cells), safety and public education underscore future opportunities. Intergovernmental bodies such as Asia Pacific Economic Cooperation (APEC), International Energy Agency (IEA) and the International Partnership for the Hydrogen Economy (IPHE) provide a multilateral framework for development of a global hydrogen economy. While the pathway forward for the hydrogen economy is precarious alternative energy options offer substantially fewer public benefits. [ABSTRACT FROM AUTHOR]

The paper acknowledges the political nature of environmental protection and climate change in the United States and the grassroots demand for environmental protection as a phase of economic development. It argues that grassroots support is more reliable than top-down authority in ensuring a clean environment as it reflects the desire for local control and the utilization of local human resources. Young people play a vital role in finding grassroots solutions in their respective communities. For instance, implementing a topdown policy of legally-binding carbon taxes worldwide might be desirable in theory, but in reality, leads to political stalemate. The more realistic and efficient solution is to substitute pollution-prone technology that is currently in use with renewable and sustainable technology. Technological change brings about economic change, in turn fostering social change in perceptions and values, strengthening political support at the local level for environmental protection. This is more durable than top-down authoritarian support for environmental protection that vests decision-making power in a single political leader or in-crowd of government officials. Without grassroots support, the transition to a renewable resource-based economy that has a sustainable relationship with the environment cannot take place. [ABSTRACT FROM AUTHOR]

Wind power is a type of clean and renewable energy, and reasonable utilization of wind power is beneficial to environmental protection and economic development. Therefore, a short-term hydro-thermal-wind economic emission dispatching (SHTW-EED) problem is presented in this paper. The proposed problem aims to distribute the load among hydro, thermal and wind power units to simultaneously minimize economic cost and pollutant emission. To solve the SHTW-EED problem with complex constraints, a modified gravitational search algorithm based on the non-dominated sorting genetic algorithm-III (MGSA-NSGA-III) is proposed. In the proposed MGSA-NSGA-III, a non-dominated sorting approach, reference-point based selection mechanism and chaotic mutation strategy are applied to improve the evolutionary process of the original gravitational search algorithm (GSA) and maintain the distribution diversity of Pareto optimal solutions. Moreover, a parallel computing strategy is introduced to improve the computational efficiency. Finally, the proposed MGSA-NSGA-III is applied to a typical hydro-thermal-wind system to verify its feasibility and effectiveness. The simulation results indicate that the proposed algorithm can obtain low economic cost and small pollutant emission when dealing with the SHTW-EED problem. [ABSTRACT FROM AUTHOR]

Renewable energy is an important factor in achieving a low-carbon economic development path in China. This paper investigates the factors influencing renewable electricity consumption in China. Specifically, the factors that influence the share of renewable electricity in total electricity consumption in China is investigated using data from 1980 to 2011 and employing the Johansen cointegration technique and vector error correction model. The result of the analysis shows that there is a long run relationship between renewable electricity consumption and GDP per capita, trade openness, foreign direct investment, financial development and share of fossil fuel in energy consumption. Economic development and financial development promotes renewable electricity consumption while foreign direct investment, trade openness and the lobby of conventional energy sources undermine the share of renewables in total electricity consumption in China. While the effects of shocks to the other variables appear to die out over time, the “lobby effect” is persistent and explosive. The results also show that there is a uni-directional short run causality from financial development to renewable electricity consumption and from renewable electricity consumption to trade openness. The Chinese government should pursue policies that not only increase the amount of renewable electricity, but also increase the share of renewables in total electricity consumption.

Abstract: The capacity expansion planning is a crucial process taking into account multiple aspects and various parameters of the examined power sector in order to optimally satisfy the future electricity demand. In the case of Greece, the long-term energy planning of the electricity supply sector faces a lot of challenges deriving from the peculiarities and geomorphology of the country mainly referring to the large number of islands. This paper explores the feasibility and the consequences of interconnecting Greek islands to the mainland grid by establishing two alternative scenarios of least cost electricity planning for the period 2009–2020. Namely, the reference scenario assumes isolated electric systems of islands and is compared against the alternative option of their interconnection to the mainland. The main purpose of the present study is to illustrate the great importance of islands’ interconnection on the development of renewable energy sources (RES) to generate electricity while pointing out the consequent economic and environmental benefits.

Decentralizedenergy planning (DEP) is in the interest of efficient utilization of resources. DEP is one of the options to meet the rural and small scale energy needs in a reliable, affordable, and environmentally sustainable way. The main aspect of the energy planning at the decentralized level would be to prepare an area-based DEP to meet energy needs and development of alternate energy sources at least cost to the economy and environment. The geographical coverage and scale reflect the level at which the analysis takes place, which is an important factor in determining the structure of models. DEP planning involves multiple objectives and different kinds of constraints. The present work presents the methodology for the DEP. The kinds of objective functions and constraints which have to be included in the DEP have been presented in the present work. Decentralized planning involves scaling down energy planning to subnational or regional scales. Energy planning at the village level is the lowest level of the application of decentralized planning principle and district is the uppermost level. The present work for the analysis of DEP at the village level has considered different scenarios. Conflicting objectives are considered in the implementation of DEP at the village level. This implementation has been shown through a case study done in a village named Ungra in the Tumkur district from the Karnataka state in India. DEP is assessed with the help of field studies, available data, and decentralized energy modeling. Through DEP energy demand at 2020 has been presented for the Ungra village. [ABSTRACT FROM AUTHOR]
