Comprehensive Study of Different Renewable Energy Resources such as Hydro Energy, Solar Energy and Wind Energy

Depletion of fossil fuel resources is the main cause of hike in fossil fuel price which lead to concern for alternate resources of energy such as nuclear energy, renewable energy resources but Fukushima Daiichi accident was a turning point in the call for renewable energy. Now it is considered that renewable energy resources are more desirable source of fuel than nuclear power due to the absence of risk and disasters. In order to meet challenges, future energy policies should put more emphasis on developing the potential of energy sources, which include hydro energy, solar energy biofuel energy, wind energy all these comes under renewable energy resources. By replacing fossil fuels with renewable energy sources Co 2 emission in environment can be reduced which is the main factor for greenhouse gas effect. In this paper, the alternative resources of renewable energy are studies.
