The Impact

Abstract This study adopted two-stage DEA to estimate the technical efficiency scores and assess the impact of the two most important components of fossil fuel associated with oil production on macroeconomic efficiency of Seven oil producing African countries during 2005-2012. Our results showed that increasing the consumption of natural gas would improve technical efficiency. Furthermore, increasing the share of fossil fuel in total energy consumption has negative effect on the efficiency of the economies of the top African oil producers. Also, we found that increasing the consumption of primary energy improves efficiency in these economies. We therefore, recommend that governments and other stakeholders in the energy industry should adopt inclusive strategies that will promote the use of natural gas in the short term. However, in the long-run, efforts should be geared towards increasing the use of primary energy, thereby reducing the percentage share of fossil fuel in total energy consumption.

The physiology of the fetal heart differs significantly from that of the mature post-natal organ: e.g., the metabolic supply for adult cardiac contraction relies mainly on fatty acids; whereas, the fetal heart uses carbohydrates as its primary energy source. Limited morphological descriptions of the developing myocardium have appeared. However, additional studies are required to elucidate the ultrastructural changes occuring in the perinatal period when enormous physiological adjustments are made. Although adult animals are most often used in toxocological and pathological analyses, it is also important to investigate fetal cardiac responsiveness to various agents. The vulnerability of the ultrastructure of the fetal mouse myocardium to genetic and environmental assault is the subject of this report. The genetically determined effect on the heart was observed in mouse embryos homozygous for the cab (cardiac abnormality) mutation discovered by Essien.

Production Regime

The article analyzes the dynamics of consumption of primary energy and production of electrical energy in the world for 1973-2012 and the volume of renewable energy. It is shown that in the crisis year of 20 0 9 there was a significant reduction in primary energy consumption and production of electrical energy. At the same time, renewable energy has developed rapidly, well above the rate of the world economy growth. The development of renewable energy is one of the most effective ways out of the crisis, taking into account its production regime, energy, environmental, social and economic efficiency. The forecast for the development of renewable energy for the period up to 2020, compiled by the IEA, is analyzed. It is shown that its assessment rates are conservative; the authors justify higher rates of development of renewable energy.

Kazakhstan’s economic policy in 1996-2007, its character and the degree of responsibility, the correlation between economic development and balance of current accounts are considered in the article. Special attention is paid to the analysis of their macroeconomic efficiency. It is concluded that in conditions of high rates of economic growth in Kazahkstan in 2000-2007 the net profits of foreign investors are 10-11% of GDP every year. The tendency of negative balance of current accounts in favor of foreign investors is also analyzed.

Industrial heat pumps are heat-recovery systems that allow the temperature ofwaste-heat stream to be increased to a higher, more efficient temperature. Consequently, heat pumps can improve energy efficiency in industrial processes as well as energy savings when conventional passive-heat recovery is not possible. In this paper, possible ways of saving energy in the chemical industry are considered, the objective is to reduce the primary energy (such as coal) consumption of power plant. Particularly the thermodynamic analyses ofintegrating backpressure turbine ofa power plant with distillation units have been considered. Some practical examples such as conventional distillation unit and heat pump are used as a means of reducing primary energy consumption with tangible indications of energy savings. The heat pump distillation is operated via electrical power from the power plant. The exergy efficiency ofthe primary fuel is calculated for different operating range ofthe heat pump distillation. This is then compared with a conventional distillation unit that depends on saturated steam from a power plant as the source of energy. The results obtained show that heat pump distillation is an economic way to save energy if the temperaturedifference between the overhead and the bottom is small. Based on the result, the energy saved by the application of a heat pump distillation is improved compared to conventional distillation unit.

The article assesses prospects of the Russian-Korean cooperation and analyzes risks and opportunities of the trilateral energy projects on the Korean Peninsula. The author noted that energy sector is the key area of bilateral cooperation between Russia and the Republic of Korea, but it’s mainly represented by the trade in primary energy resources. The study identified the export potential of Russian hydrocarbons to the market of the Republic of Korea. As for the DPRK, the paper shows that within bilateral relations geopolitical interests prevail over the economic ones. The small capacity of the DPRK's domestic market and the absence of fixation sources do not allow considering it as an independent full-fledged market for the Russian energy resources. The main goal of the energy strategy of Russia and the Russian Far East is increasing the volume of exports of the primary energy resources to the APR countries. Russian prospects for the new product niches in the energy markets of the Republic of Korea are associated with the implementation of trilateral energy projects among Russia, the DPRK and the Republic of Korea. It includes creation of the interstate power transmission lines and construction of a gas pipeline. All parties are interested in these projects. As for Russia, it is primarily the expansion of energy exports, including occupation of the commodity niches in new markets, and strengthening of the political role in the region. As for the Republic of Korea, these projects mean diversification of supplies and costs’ reduction of the import energy resources. And as for the DPRK, these projects imply an additional source of financing (as payment for transit), improvement of the country's energy infrastructure and reduction of the deficit of energy resources. Despite the prospects, the author determined that in the near future implementation of the projects is unlikely due to the unresolved transit risks.

This chapter reviews relevant literature on the current state and effectiveness of developing renewable energy on energy security in general, and on energy security in the European Union (EU) in particular. The chapter elaborates on primary energy import sources, possible alternatives, and how energy security is affected by the sources of supply. It also gives an analysis of the effects of the Ukrainian crisis, the isolation of Iran on diversification sources, and on European energy security. It examines EU’s energy policy, analyses the best motivation for a new energy policy direction within Europe, and suggests alternative solutions for enhanced energy supply security. The aim is to suggest suitable solutions for energy security in Europe through energy supply diversification. Supply diversification includes alternative energy corridors for reducing dependency on Russia as a supplier and enhancing the power generated by renewable energy sources under the European Union 2020 strategy.
