A Review of Renewable Energy Resource like Wind Energy and Solar Energy

The demand for electricity is increasing day by day, which cannot be fulfilled by non-renewable energy sources alone. Renewable energy sources such as solar and wind are present every were and environmental friendly. The renewable energy sources are emerging options to fulfil the energy demand, but unreliable due to the stochastic nature of their occurrence. Hybrid renewable energy system (HRES) combines two or more renewable energy sources like wind turbine and solar system. The objective of this paper is to present a comprehensive review of various aspects of Hybrid renewable energy system. There are some particular limitations that ruin the development of solar and wind energy system in India. India has satisfactory daylight and balanced wind speed. Hence there is greater opportunity for extension of solar and wind energy system in the Indian scenario along with enough future scope for these renewable sources through "Grid Parity". The aim of this paper is to present in a coherent and integrated way the major constraints hampering the development of renewable energy in India.
