Renewable Capacity Highlights Summary (April 11, 2022)

Core Content

At the end of 2021, global renewable generation capacity reached 3,064 GW, representing a 9.1% increase compared to the previous year. The net increase was 257 GW, with solar and wind energy accounting for 88% of all new renewable capacity added. Asia was the largest contributor to new capacity, adding 60% of the global total, or 154.7 GW, bringing its total capacity to 1,456 GW (48% of the global total). China was the leading country in renewable capacity expansion, adding 121 GW in total, with significant contributions from solar (+53 GW) and wind (+46.9 GW).

Key Statistics

• Annual Growth: 9.1%
• Net Increase in 2021: 257 GW
• Solar and Wind Combined Share: 88%
• Renewables in Net Capacity Expansion: 81%
• Renewables in Total Generation Capacity: 38.3% (up from 36.6% in 2020)

Regional Breakdown

Highlights by Technology

• Hydropower: Expanded by 19 GW (+2%), with China adding 14.6 GW and Canada adding 1.3 GW.
• Solar Energy: Grew by 76 GW in 2021, with China (+53 GW), India (+10.3 GW), Japan (+4.4 GW), and Republic of Korea (+3.6 GW) leading the expansion. The U.S. added 19.6 GW, and Brazil, Germany, Netherlands, and Spain added over 5 GW each.
• Wind Energy: Increased by 93 GW (+13%), with China (+46.9 GW) and U.S. (+14 GW) as the top contributors. Offshore wind accounted for 7% of total wind capacity.
• Bioenergy: Expanded by 10.3 GW (+8.3%), with China (+6.2 GW) and North America (+1.3 GW) leading the growth.
• Geothermal Energy: Grew by 1.6 GW, with U.S. (+1.3 GW), Indonesia (+146 MW), Turkey (+63 MW), and Mexico (+25 MW) as key contributors.
• Off-Grid Electricity: Increased by 466 MW (+4%), reaching 11.2 GW. Solar accounted for 312 MW, hydro for 113 MW, while bioenergy and other remained stable at 4.5 GW.

Key Observations

• Asia dominated the global renewable capacity expansion, with China playing a central role.
• Solar and wind continued to be the main drivers of renewable growth, together accounting for 88% of new capacity.
• Renewables accounted for 81% of the net capacity expansion in 2021, up from 79% in 2020.
• Non-renewable capacity expanded in Asia, the Middle East, and Africa, but net decommissioning continued in Europe and Eurasia.
• Energy transition requires that renewable capacity expansion outpaces energy demand growth to reduce reliance on non-renewables.

Data Notes

• The 2021 figures were slightly revised upward from the August 2021 estimates, primarily due to improved reporting of distributed solar power and new data for off-grid generation.
