This illustration presents the outline of this introduction to the renewable energy source discussion.
Renewable energy sources or simply renewables include solar and wind power, geothermal, biomass, and conventional hydroelectric power. Biomass in turn includes wood, wood waste, biogenic municipal waste, landfill gas, corn, sugar cane, switch grass, and other biomass. By definition, these represent resources that are relatively inexhaustible or are replaceable by new growth, with the caveat that hydropower is dependent on availability of water and the operation of the hydrologic cycle.
