Renewable energy is from an energy resource that is replaced rapidly by a natural process such as power generated from the sun or from the wind.
Renewable energy is any energy source that is naturally replenished, like that derived from solar, wind, geothermal or hydroelectric action. Energy produced from
the refining of biomass is also often classified as renewable. Coal, oil or natural gas, on the other hand, is finite sources. Renewable energy may be defined as energy from naturally available sources that is constantly replenished and can be harnessed for human benefit. Although the concept of renewable energy is simple, the technology used to extract and deliver the energy is rapidly developing and becoming more advanced.
Renewable energy is derived from solar radiation, directly or indirectly. The amount of solar energy directed at the earth yearly is equivalent to more than 15,000 times the world’s annual use of fossil and nuclear fuels and 160 times the energy stored in the world‘s proven fossil fuel reserve. The use of renewable energy and the systems associated with it are generally referred to as ‘renewables’.
