Using of renewables energies such as effective way to reduce environmental pollution

Much of the energy consumed in the world is fed by fossil fuels. These fuels have a variety of toxic and hazardous pollutants. Through various means to the environment and finally enter the human food chain. Although the environmental impacts of the use of fossil fuels on surface water, groundwater, soil, air, vegetation, and so on are numerous. But the topics of air pollution, greenhouse effect and particles and their cooling effect More attention is being paid. Maintain current situation of life in human society in the future without regard to cost-effective energy supply is not possible. Environmental impacts associated with each energy production at the current rate continues to unacceptable conditions and the harmful environmental effects are expanding extensively. Renewable energy as a power source and free of environmental pollution can Play an important role in reducing pollutant emissions such as carbon dioxide and other greenhouse gases. Therefore, in this research, we try to investigate the role of various renewable energies in reducing environmental pollution.
