energia, mida kogutakse taastuvatest ressurssidest, mida loomulikult täiendatakse inimese aja jooksul, sealhulgas CO2-neutraalsed allikad, nagu päikesevalgus, tuul, vihm, tõusud, lained ja geotermiline soojus
energy that is collected from renewable resources, which are naturally replenished on a human timescale, including carbon neutral sources like sunlight, wind, rain, tides, waves, and geothermal heat
Taastuvenergia tüüpi energiaallikad on vastuolus fossiilkütustega, mida kasutatakse palju kiiremini kui neid täiendatakse. Kuigi enamik taastuvenergiast on säästev energia, ei ole mõned neist, näiteks osa biomassist, jätkusuutlik.
The renewable energy in contrast to fossil fuels, which are being used far more quickly than they are being replenished. Although most renewable energy is sustainable energy, some is not, for example some biomass is unsustainable.
