Depth Analysis

Different power generation technologies have different advantages and disadvantages. However, if compared to traditional energy sources, renewable energy sources provide a possibility to solve the climate change and economic decarbonization issues that are so relevant today. Therefore, the analysis and evaluation of renewable energy technologies has been receiving increasing attention in the politics of different countries and the scientific literature. The household sector consumes almost one third of all energy produced, thus studies on the evaluation of renewable energy production technologies in households are very important. This article reviews the scientific literature that have used multiple-criteria decision-making (MCDM) methods as a key tool to evaluate renewable energy technologies in households. The findings of the conducted research are categorized according to the objectives pursued and the criteria on which the evaluation was based are discussed. The article also provides an overview and in-depth analysis of MCDM methods and distinguishes the main advantages and disadvantages of using them to evaluate technologies in households.

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.

Improving energy efficiency is one of the main ways to reduce energy pollution that leads to economic development, increasing energy access and better life. That can result in reducing fossil fuel use and growing clean energy supplies. The Gulf countries have as many renewable resources as hydrocarbons like sunshine, considerable wind resources, and geothermal. The economy of the Middle east deeplydepends on fossil fuel export. Declining fossil fuel supplies and rising energy prices are driving global energy supplies to renewables energies. Although the Middle East region, due to its special geographical features, has significant potential for the growth of renewable energy sources, they have not been developed yet. It overviews the energy situation and sustainability, economic potential of renewable energy, policies for energy systems over the recent decades in six resource-rich countries in the middle east. In addition, along with renewable energy technologies, possible ways to solve current environmental problems are recognized. The methodology of this work is PESTLE analysis of these countries' energy status to develop a long-term mechanism for sustainable and secure energy for the Middle East based on Political, Economic, Social, Technological, Legal, Environmental. Also, it identifies challenges that restrict the development of renewable energy technologies in the Middle East. By analyzing the status of energy in recent decades, the importance of implementation of effective energy policies to develop sustainable energy can be realized. Key words: energy source, sustainable future, renewable, effective policy, resource-rich countries.

Environmentalists continuously push for us, as a country, to decrease our fossil fuel usage and transition to a society powered by renewable energy. The money of oil companies and other corporations persuade our government to continue investing in fossil fuels as opposed to renewable energy. There are, however, other reasons which should convince us as a nation to invest in alternative energy sources. Eliminating our dependence on fossil fuels will benefit the nation economically and prepare us for a rapidly changing future. We, as Americans, should increasingly pursue renewable sources of alternative energy not only for the documented environmental reasons but also because investing in renewable energy technologies will provide jobs for Americans, decrease our dependence on other nations, and benefit the health of all Americans while decreasing our dependence on fossil fuels.

The Hierarchical Structure

Renewable Energy (RE) technologies are increasingly viewed as crucially important. Knowledge that helps to predict the likely growth of emergent technologies is essential for well-informed technology management. The vast amount of available data in publications hinders the acquisition and analysis of this knowledge. Therefore, there is a need for intelligent search techniques capable of grouping semantically similar concepts together, such that, for example, terms containing “photovoltaic” are hierarchically subsumed under solar energy-related technologies. Consequently, articles related to “Photovoltaics” should be included in the analysis. To accommodate this in an automated fashion, the authors deploy a renewable energy taxonomy for comprehensive trend discovery in publications and patents. This taxonomy is based on the hierarchical structure of Wikipedia categories and their subordinate Wikipedia terms. This paper analyzes promising trends of renewable energy sources in two case studies: power generation and desalination techniques.
