About 16% of global final energy consumption comes from re-newables, with 10% coming from traditional biomass
, which is mainly used for heating
, and 3.4% from hydroelectricity
New re-newables (small hydro, modern biomass, wind, solar, geothermal, and biofuels) accounted for another 2.8% and are growing very rapidly.
The share of re-newables in electricity generation
is around 19%, with 16% of global electricity coming from hydroelectricity and 3% from
