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

Informative Speech April 24‚ 2011 Energy Efficiency There are various sources of energy available for use. However‚ energy is a limited and sparse resource that is not in abundance at all places. There is an ever rising need for more energy‚ but the energy supply and resources are limited. As a result‚ people have to develop means that can enable them to survive with the small amount of energy that is available. The proper and sustainable use of energy is known as energy efficiency. Efficiency is attained
