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 al...
EERE's applied research, development, and demonstration activities aim to make renewable energy cost-competitive with traditional sources of energy. Learn more about EERE's work in geothermal, sola...
Renewable energy is energy derived from natural sources that are replenished at a higher rate than they are consumed. Sunlight and wind, for example, are such sources that are constantly being repl...
Learn about the Energy Department's investments in clean, renewable energy technologies including wind, solar, hydro, geothermal, bioenergy & nuclear.
A large chunk of the greenhouse gases that blanket the Earth and trap the sun’s heat are generated through energy production, by burning fossil fuels to generate electricity and heat. Fossil fuels, such as coal, oil and gas, are by far the largest contributor to global climate change, accounting for over 75 percent of global greenhouse gas emissions and nearly 90 percent of all carbon dioxide emissions. The science is clear: to avoid the worst impacts of climate change, emissions need to be re...
재생 가능 에너지 (再生可能 - , 영어: renewable energy )는 재생이 가능한 자원, 즉 햇빛(태양), 바람(풍력), 비, 조수(조력), 파도(파력), 지열과 같이 시간이 지남에 따라 자연적으로 보충되는, 재생&지속이 가능한...
Renewables, including solar, wind, hydropower, biofuels and others, are at the centre of the transition to less carbon-intensive and more sustainable energy systems. Generation capacity has grown r...
Introduction of Korea`s renewable energy.
Renewable energy, usable energy derived from replenishable sources such as the Sun (solar energy), wind (wind power), rivers (hydroelectric power), hot springs (geothermal energy), tides (tidal pow...
