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.

giving a total hydropower capacity of 1 360 GW.

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 energy: With an increase in new
capacity in all major world regions in
previous years, total global solar capacity
has now outgrown wind energy capacity.
Expansion in Asia was 76 GW in 2021 (compared to
+77 GW in 2020), with major capacity increases in
China (+53.0 GW) and India (+10.3 GW). Japan also
added 4.4 GW and Republic of Korea expanded solar
capacity by almost 3.6 GW.
Outside Asia, the United States added 19.6 GW of solar
capacity in 2021, Brazil and Germany respectively
added 5.2 GW and 4.7 GW and the Netherlands and
Spain added more than 3 GW.
Wind energy: Wind expansion continued at
a lower rate in 2021 compared to 2020
(+93 GW compared to +110 GW last year).
China added 46.9 GW of new wind capacity, followed
by the United States (+14.0 GW). Eleven other
countries increased their wind capacity by more than
1 GW in 2021. While offshore wind remains a fairly small
part of the sector, it continues to increase in
importance each year and reached around 7% of total
wind capacity in 2021.
Bioenergy: Net capacity expansion
increased in 2021 (+10.3 GW compared to
+9.1 GW in 2020). Bioenergy capacity in
China expanded by 6.2 GW, leading net expansion in
Asia and the world. North America was the only other
region with significant expansion in 2021, adding
1.3 GW of bioenergy capacity.
Geothermal energy: Geothermal capacity
had an exceptional growth in 2021, with 1.6
GW added. The United States increased
capacity by 1.3 GW in 2021, and other expansions
occurred in Indonesia (+146 MW), Turkey (+63 MW),
Italy (+30 MW) and Mexico (+25 MW).
Off-grid electricity: Off-grid capacity grew
by 466 MW in 2021 (+4%) to reach 11.2 GW.*
Solar expanded by 312 MW to reach 4.9 GW
and hydro added 113 MW to reach 1.9 GW. Bioenergy
and other capacity remained almost unchanged at
about 4.5 GW.

Renewable share of annual power capacity expansion
In 2021, renewable generating capacity expansion
slowed down slightly compared to 2020, while staying
well above the long-term trend. Most of this expansion
occurred in China and, to a lesser extent, the United
States. Most other countries continued to increase
renewable capacity at a similar rate to previous years.
The share of renewables in total capacity expansion
reached 81% in 2021, compared to the figure of 79% in
2020. The renewable share of total generation
capacity rose by almost two percentage points from
36.6% in 2020 to 38.3% in 2021.
The upward trend in these shares reflects not only the
rapid and increasing growth of the use of renewables
but also the declining expansion of non-renewable
capacity. At the global level, the latter is also affected
by the large amount of net decommissioning that has
occurred for many years in some regions.
In 2021, non-renewable capacity continued to expand
in Asia, the Middle East and Africa (but with a much
lower expansion in Middle East and Africa), while net
decommissioning continued in Europe and Eurasia.
An energy transition requires that the use of
renewables expands by more than the growth in
energy demand, so that less non-renewable energy
needs to be used. Many countries still have not reached
this point, despite dramatic increases in their use of
renewables for generating electricity.
Latest figures compared to previous estimates
Compared to the capacity statistics published in
August 2021, the figures here have been revised
upwards very slightly. Total renewable capacity in
2020 was reported as 2 802 GW last year and the new
figure for 2020 is 2 807 GW (+0.18%).
As noted last year, most revisions can be explained by
imprecise early reporting of distributed solar power
generation in a few countries (which is often
overstated). Upward revisions were also made this
year for a few countries where data were not available
and estimates were made last year.
The other main revision has been an increase in the
time-series for off-grid generation, where new figures
have been found. Given the importance of increasing
energy access and the widespread use of solar power
for this purpose, countries are encouraged to continue
expanding the collection of off-grid data for
monitoring their national energy goals and targets.
