Electricity generation, one of the renewable energy sources (RES), delivers a solution for various problems such as energy efficiency, energy supply security, reducing foreign dependency, and especially, environmental concerns. However, the solutions provided for these problems bring along the question of which RESs are produced more effectively. Therefore, in this research, RESs used for electricity generation in Turkey were analyzed by using generation data to show which one is more effective. Bi-objective multiple-criteria data envelopment analysis (BiO-MCDEA) method, a goal programming-based efficiency determination method, was used for the efficiency analysis conducted for five years between the years of 2014 and 2018. As a result of the analysis, geothermal energy came into prominence as the most effective RES for all of the years included in the solution. Geothermal energy was followed by biomass energy, wind energy, hydroelectric, and solar energy, respectively.

Different Sources

This paper discusses and analyzes the economics for total cost investment to produce electricity from different sources like Geothermal Energy, Wind Energy, Hydro, Nuclear, Solar, etc. Renewable energy is the focus of this study since it is both affordable and a superior solution than non-renewable energy. The world's nonrenewable energy supply is running out, and prices are rising rapidly. As a result, the use of renewable energy sources is steadily growing. The total installed cost of different sources from 2007-2019 is driven clearly in this paper. An overall discussion on electricity generation is also included in this paper.

Regional Sustainable Development

In this paper, the author focuses on the fundamental hypothesis that the adoption of a concept of regional sustainable development and the use of renewable energy sources are preconditions to organising an acceptable regional tourism offering based on an eco-philosophy The renewable development of tourism regions is the basic framework for research regarding opportunities for introducing renewable energy sources such as hydro energy, wind power, solar energy, geothermal energy, and biomass energy. The purpose of this paper is to indicate the real opportunities that exist for substituting conventional energy sources with renewable ones and the role of renewables in regional development from economic, environmental and sociological viewpoints. It should also be noted that renewable energy sources have a strong regional importance and can contribute significantly to local employment.

Primary Energy Supply

The study analyzes the economics of renewable energy sources into electricity generation in Tanzania. Business as usual (BAU) scenario and renewable energy (RE) scenario which enforce a mandatory penetration of renewable energy sources shares into electricity generations were analyzed. The results show total investment cost for the BAU scenario is much lower as compared to RE scenario while operating and maintenance variable costs are higher in BAU scenario. Primary energy supply in BAU scenario is higher tied with less investment costs as compared to RE scenario. Furthermore, the share of renewable energy sources in BAU scenario is insignificant as compared to RE scenario due to mandatory penetration policy imposed. Analysis concludes that there are much higher investments costs in RE scenario accompanied with less operating and variable costs and lower primary energy supply. Sensitivity analysis carried out suggests that regardless of changes in investments cost of coal and CCGT power plants, the penetration of renewable energy technologies was still insignificant. Notwithstanding the weaknesses of renewable energy technologies in terms of the associated higher investments costs, an interesting result is that it is possible to meet future electricity demand based on domestic resources including renewables.

Abstract The relevancy of the study is due to low efficiency of using solar and geothermal energy in the existing process schemes. In this regard, this article is aimed at revealing the possibilities of using solar and geothermal energy for the integrated energy supply of separate facilities from renewable energy sources. The mathematical simulation method based on the theory of graphs of energy system operation, which makes it possible to analyze the efficiency of the integrated use of solar and geothermal energies for the heat-cold supply of separate facilities, is the main approach to studying this problem. Energy consumption throughout the year and the emergency energy source capacity in “peak” modes were determined based on the developed mathematical model of managing the system of integrated power supply of separate facilities from renewable energy sources plotted with the use of the theory of graphs. The article materials are of practical value for the designers of the systems of integrated heat-cold supply of separate facilities.
