Renewable energy comes from resources which never are continually renewed by natural processes, such as sunlight, wind, rain, tides, and geothermal heat

Renewable energy is potentially environmentally friendly, but not always. The "old renewables, bioass and hydroelectricity, generally have massive negative impacts:

In 2006, about 18% of global final energy consumption came from renewables, but this is almost all from the old, damaging renewables: 13% from traditional biomass, mainly for heating, and 3% from hydroelectricity. "New renewables (small hydro, modern biomass, wind, solar, geothermal, and biofuels) accounted for only 2.4%, but are growing very rapidly.[verification needed]
