Renewable capacity highlights 11 April 2022 Renewable generation capacity by energy source At the end of 2021, global renewable generation capacity amounted to 3 064 GW. Hydropower accounted for the largest share of the global total, with a capacity of 1 230 GW.* Solar and wind energy accounted for equal shares of the remainder, with capacities of 849 GW and 825 GW respectively. Other renewables included 143 GW of bioenergy and 16 GW of geothermal, plus 524 MW of marine energy. Renewable power capacity growth Renewable generation capacity increased by 257 GW (+9.1%) in 2021. Solar energy continued to lead capacity expansion, with an increase of 133 GW (+19%), followed by wind energy with 93 GW (+13%). Hydropower capacity increased by 19 GW (+2%) and bioenergy by 10 GW (+8%). Geothermal energy increased by 1.6 GW. Solar and wind energy continued to dominate renewable capacity expansion, jointly accounting for 88% of all net renewable additions in 2021. Along with the higher growth of geothermal, this growth in wind and solar led to a high annual increase in renewable generating capacity. ______________________________________________________________________________ * Note: these figures exclude pure pumped storage. At end-2021, this was an additional 130 GW, giving a total hydropower capacity of 1 360 GW. 05001,0001,5002,0002,5003,0002016 2017 2018 2019 2020 2021HydropowerSolarWindBioenergyGeothermal0255075100125150Capacity added in 2021GWHEADLINE FIGURES 3 064 GW Global renewable generation capacity at the end of 2021 9.1% Growth in renewable capacity during 2021 257 GW Net increase in global renewable generation capacity in 2021 60% Share of new renewable capacity installed in Asia in 2021 88% Wind and solar share of new renewable capacity in 2021 81% Share of renewables in net capacity expansion in 2021 IRENA’s renewable energy statistics can be downloaded at: www.irena.org/statistics 40%28%27%5%HydroSolarWindOthers Renewable generation capacity by region For the complete dataset see: IRENA (2022), Renewable capacity statistics 2022, available at: www.irena.org/publications. Asia accounted for 60% of new capacity in 2021, increasing its renewable capacity by 154.7 GW to reach 1.46 TW (48% of the global total). A huge part of this increase occurred in China (+121 GW). Capacity in Europe and North America expanded by 39 GW (+6.4%) and 38 GW (+9.0%) respectively, with a notably large expansion in the USA (+32 GW). Africa continued to expand steadily with an increase of 2.1 GW (+3.9%), slightly less than in 2020. Oceania is no longer the fastest growing region (+5.2%), although its share of global capacity is small and almost all of this expansion occurred in Australia. Highlights by technology Hydropower: Growth in hydro increased steadily in 2021, with the commissioning of several large projects delayed through 2021. China added 14.6 GW of capacity, followed by Canada with 1.3 GW. Solar
