SummaryOverviewMainstream technologiesEmerging technologiesMarket and industry trendsPolicyFinanceDebates

Renewable energy (or green energy) is energy from renewable natural resources that are replenished on a human timescale. The most widely used renewable energy types are solar energy, wind power, and hydropower. Bioenergy and geothermal power are also significant in some countries. Some also consider nuclear power a renewable power source, although this is controversial. Rene
