Renewable Energy



Renewable Energy is the form of energy derived from natural sources or processes which are constantly replenished. These sources may be available for a limited amount of time in a year but are virtually inexhaustible. For example, sunlight, wind, geothermal energy, rain, tidal waves, etc. The usage of renewable energies is very old as the wind has been used in sailing boats and sunlight for heating, but with the advent of new electronic technologies, renewable energy has been redefined as the natural source or processes which can be converted into electrical energy. The renewable energy sources have a long range in terms of their scale – a renewable energy source may be a rooftop solar panel or as large as an array of wind turbines at the sea-shore. According to the International Energy Agency (IEA), renewable energy had more than 28% share of the global energy supply in more on NOPR
