Analysis of effecting renewable energy consumption on environment according to role of human capital
The limitation of non-renewable resources and the increasing of environmental pollution caused by the accumulative consumption of fossil fuels indicate the necessity of paying attention to renewable sources. The present study analyzes the factors affecting on the quality of the environment with emphasis on the consumption of renewable energy and human capital such as education in developing and...
Environmental pollution is mainly caused by carbon emissions, so emission reduction our top priority now. Carbon-containing greenhouse gas emissions come from the following aspects: (1) fossil fuel combustion; (2) leakage and volatilization in process of extraction, processing, transportation, industrial utilization; (3) traditional biomass combustion. The effect will cause an increase temperat...
This paper contributes towards exploring the technical and institutional feasibility of small hydropower storage and pumped-storage schemes in Switzerland. Within the European and Swiss context of the facilitation of renewable energy technologies, which includes small hydropower (SHP), intermittent sources such as solar and wind increase the need for additional energy storage capacities. Hydrop...
Electricity is one of the most important carriers of energy used in buildings. By introducing energy smart grids (SG) and energy micro smart grids (MSGs) alongside smart buildings, a good platform has been provided for optimal planning of electricity production and consumption. In this paper, an MSG consists of renewable resources, diesel generators and cell batteries in bidirectional connectio...
Coal is most important fossil fuel in world. Energy requirement of world is increasing in many fields day by day. The crude oil and coal are the main backbone of energy. Since the reserves of crude oil are decreasing day by day as a result the coal becomes the main sources of fossil fuel. Ash content of Indian coal is very high ranging from 15% to 55% [1]. Ash is an inorganic compound present i...
Although fossil fuels consumption may causes to rapid economic growth, but due to related pollutants and its consequences, the world has suffered from climate changes. Moreover, fossil fuel resources such as petroleum, gas, coal and uranium are being exhausted rapidly in the last decades. Therefore, seeking an appropriate as well as low-cost alternative for the above-mentioned energy carriers i...
Considering rapidly rising air pollution and unemployment problem in Turkey, renewable energy may be the most appropriate solution for both of problems. While positive effect on environement is widely acknowledged, there isn’t sufficient research about its employment statistics. For this reason, study, net benefit renewable-based electricity sector, against fossil-based investigated through Inp...
Due to the increasing efforts on saving our natural environment a change in the structure of energy resources can be observed an increasing fraction of a renewable energy sources. In many countries traditional underground coal mining loses its significance but there are still countries, like Poland or Germany, in which the coal based technologies have the greatest fraction in a total energy pro...
This paper provides an overview of the expected role that variable speed hydro power plants can have in future electric power systems characterized by a massive integration of highly variable sources. Therefore, it is discussed the development of a methodology for optimising the operation of hydropower plants under increasing contribution from new renewable energy sources, addressing the partic...
