In 2015, renewable electricity capacity expanded at its fastest pace to date with 153 GW of new grid-connected capacity becoming operational. Wind power represented over 40% (66 GW) of these additions, followed by solar PV (49 GW) and hydropower (31 GW). Renewable electricity generation is expected to grow by 36% from an estimated 5 660 TWh in 2015 to 7672 TWh in 2021, driven by policies aimed at enhancing energy security and sustainability. The share of renewables in global electricity generation is expected to increase from over 23% in 2015 to 28% in 2021 as renewable power output is anticipated to grow much faster than global power from coal, natural gas and overall electricity generation.
