Renewable energy
Renewable energy is energy made 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. Renewable energy installations can be large or small and are suited for both urban and rural areas. Renewable energy is often deployed together with further electrification. This has several benefits: electricity can move heat and vehicles efficiently and is clean at the point of consumption. Variable renewable energy sources are those that have a fluctuating nature, such as wind power and solar power. In contrast, controllable renewable energy sources include dammed hydroelectricity, bioenergy, or geothermal power.

Renewable energy
Renewable energy is energy harnessed from naturally replenishing sources on a human timescale, such as solar radiation, wind , flowing water, geothermal reservoirs, biomass , and ocean tides, which generate power without depleting finite stocks like fossil fuels. In 2023, these sources accounted for 30% of global electricity generation , with hydropower as the dominant contributor at 14%, while wind and solar rapidly expanded to comprise a growing share through unprecedented capacity additions exceeding 500 gigawatts annually, driven by cost reductions of over 80% for solar photovoltaics and 70% for onshore wind since 2010 via technological learning and scale. However, renewables met only about 15% of total primary energy demand that year, constrained by the intermittency of solar and wind —necessitating backup from dispatchable sources or costly storage to maintain grid reliability—and their lower energy densities, which demand extensive land areas for equivalent output compared to denser fuels, sparking debates over environmental trade-offs including habitat fragmentation and resource extraction for manufacturing.
