It is estimated that at least 600 million people in Africa lack access to electricity and three out of five people don’t have access to electricity in Sub-Saharan Africa. Though Africa is rich in a wide range of energy resources including solar, bio, natural gas, oil, coal and Uranium, the continent is far from energy self-sufficiency. Addressing climate change will require deep and quick reductions in fossil fuel use so that the systems developed around producing, transporting, and consuming energy are decarbonized by the middle of the century. In the ongoing age, sustainable power source has taken another swing to limelight on the planet, particularly in developed and emerging nations, as it assumes a noteworthy part both in economy and the general job of the world. Significantly, Nigeria an oil-rich country, comes as no surprise that almost all of her energy consumption comes from non-renewable energy sources as coal, natural gas and oil, and as such it is highly vulnerable to shocks due to overdependence on the fossil sources; often time is controlled by the international market. On the whole, the fossil fuel is expected to span only but a millennium (1700-2700) of human civilization while the imperative of an energy shortage situation is felt in every sector of the country considering the poor electricity consumptions in the country, which has reflected on the country’s economy and productivity rate. In revamping the economic sectors in Nigeria, the need for an alternative energy sources that is augmentable in supply keeping in view sustainable development as the hallmark for all sector development. Thus far, Nigeria ought to likewise be opened to universal investments as this would help support the improvement of its assets. This paper, therefore, supports no other sources but renewable energy in promoting the countries productivity at all segments. It further stressed on the implementation of the country’s Renewable Energy Master Plan (REMP) to meet global competitors by the year 2030. Similarly, senior political figures, policymakers and CEOs should engage in a policy dialogue by identifying unique opportunities and best practices for developing and investing in Nigeria and in Africa’s energy markets for “…without this energy supply, the sophisticated skills of the industrial world are merely a burden in the struggle for survival.”

AbstractThis paper studies the relationship between the energy mix and the environment using a theoretical framework in which two alternative energy sources are considered: fossil fuels (dirty energy) and renewable energy (clean energy). We find that a positive aggregate productivity shock increases energy consumption and emissions but reduces energy intensity and emissions per unit of output as renewable energy consumption increases, that is, carbon emissions are procyclical but emissions per unit of output are countercyclical. Second, an energy efficiency improvement provokes a “rebound effect” above 100% (the backfire effect), resulting in a rise of pollutant emissions by increasing energy use. Third, a technological improvement in emissions leads to a reduction in emissions per unit of fossil fuel, but also implies a slow-down in the adoption of renewable energy sources. Finally, we consider the case of a decentralized economy in which the government chooses an optimal specific tax on fossil fuel to maximize social welfare. We show that the “second-best” policy is highly effective in correcting the negative effects of the environmental externality and able to almost achive the centralized economy outcome.

Thermal Power Plants

It is well known that the electrical-power generation is the key factor for advances in any other industries, agriculture and level of living. In general, electrical energy can be generated by: 1) non-renewable-energy sources such as coal, natural gas, oil, and nuclear; and 2) renewable-energy sources such as hydro, wind, solar, biomass, geothermal and marine. However, the main sources for electrical-energy generation are: 1) thermal - primary coal and secondary natural gas; 2) “large” hydro and 3) nuclear. The rest of the energy sources might have visible impact just in some countries. Modern advanced thermal power plants have reached very high thermal efficiencies (55–62%). In spite of that they are still the largest emitters of carbon dioxide into atmosphere. Due to that, reliable non-fossil-fuel energy generation, such as nuclear power, becomes more and more attractive. However, current Nuclear Power Plants (NPPs) are way behind by thermal efficiency (30–42%) compared to that of advanced thermal power plants. Therefore, it is important to consider various ways to enhance thermal efficiency of NPPs. The paper presents comparison of thermodynamic cycles and layouts of modern NPPs and discusses ways to improve their thermal efficiencies.

The article aims to study current trends in the use of solar energy in Ukraine and the world as one of the main directions of decarbonization of the national economy. The authors systematize the prospects, advantages and disadvantages of the development of renewable energy sources. They conducted a comparative analysis of the "efficiency" of solar energy in some countries and Ukraine. The authors determined that the leading position in terms of the share of energy consumed from renewable sources is occupied by countries with developed economies due to the availability of effective motivational mechanisms. From the experience of EU countries, the authors concluded that renewable energy sources form a prerequisite for obtaining additional socio-economic and environmental effects. In the presence of favorable market conditions, renewable energy sources can increase the level of energy security in the country and its energy independence. The article analyzes the legislation of Ukraine on stimulating the development of alternative energy. The authors proposed two opposed ways of further developing solar energy in Ukraine. In particular, the country can implement methods of using alternative energy, which developed countries have successfully implemented. Another area involves increasing research and innovation in implementing, using, maintaining, and utilizing energy-generating devices from alternative energy sources. Despite the polarity of the proposed directions for further development of renewable energy, in both cases, the state policy on attracting investment and promoting the use of energy from alternative energy sources is crucial. In addition, the authors noted the benefits for society from the development and implementation of alternative energy sources. The scaling up and promotion of energy production technologies from alternative sources can reduce carbon emissions, which has been an urgent problem globally.
