What is renewable energy and sources
Renewable energy refers to sources of energy that can be replenished in a short period of time. Some renewable sources are essentially infinite such as solar, wind and hydro power. Biomass and geothermal power can also be replenished, when properly managed. Renewable energy can be used as transportation fuels, to produce electricity, and for heating. Clean, renewable energy is not new, but a collection of economic, environmental and technological changes are leading to new and rapid development in the way these resources are used.
What is Alternative energy
