Renewable energy is energy that comes from resources which are continually replenished such as sunlight‚ wind‚ rain‚ tides‚ waves and geothermal heat. About 16% of global final energy consumption comes from renewable resources‚ with 10% of all energy from traditional biomass‚ mainly used for heating‚ and 3.4% from hydroelectricity. New renewables (small hydro‚ modern biomass‚ wind‚ solar‚ geothermal‚ and biofuels) accounted for another 3% and are growing very rapidly.[1] The share of renewables in
