Economic Analysis Study on the R&D Effect of Performance Improvement of the Tri-generation Fuel Cell System

Renewable generation capacity by energy sourceAt the end of 2020, global renewable generation capacity amounted to 2 799 GW.Hydropower accounted for the largest share of the global total, with a capacity of 1 211 GW.* Wind and solar energy accounted for equal shares of the remainder, with capacities of 733 GW and 714 GW respectively.Other renewables included 127 GW of bioenergy and 14 GW of geothermal, plus 500 MW of marine energy. Renewable power capacity growthRenewable generation capacity increased by 261 GW (+10.3%) in 2020.Solar energy continued to lead capacity expansion, with an increase of 127 GW (+22%), followed closely by wind energy with 111 GW (+18%).Hydropower capacity increased by 20 GW (+2%) and bioenergy by 2 GW (+2%).Geothermal energy increased by 164 MW.Solar and wind energy continued to dominate renewable capacity expansion, jointly accounting for 91% of all net renewable additions in 2020.Along with the renewed growth of hydropower, this exceptional growth in wind and solar led to the highest annual increase in renewable generating capacity ever seen.______________________________________________________________________________ * Note: these figures exclude pure pumped storage.At end-2019, this was an additional 121 GW, giving a total hydropower capacity of 1 332 GW.
