Wind and solar generated 10% of global electricity in 2021 – Ember
Wind and solar, the fastest growing sources of electricity, reach a record ten percent of global electricity in 2021; all clean power is now 38% of supply. But demand growth rebounded, leading to a record rise in coal power and emissions, according to research from Ember, a climate and energy think tank.
«Our dataset comprises annual power generation and import data for 209 countries covering the period 2000 to 2020. For 2021, we have added data for 75 countries which together represent 93% of global power demand», the research said.
Solar generation rose 23% last year, and wind by 14%. Combined, this takes them to more than 10% of global electricity generation. All clean electricity sources generated 38% of the world’s electricity in 2021, more than coal (36%).
To be on a pathway that keeps global heating to 1.5 degrees, wind and solar need to sustain high compound growth rates of 20% every year to 2030. That’s the same rate of growth as their average over the last decade.
Wind and solar generated over a tenth (10.3%) of global electricity for the first time in 2021, rising from 9.3% in 2020, and twice the share compared to 2015 when the Paris Climate Agreement was signed (4.6%). Combined, clean electricity sources generated 38% of the world’s electricity in 2021, more than coal (36%).
Fifty countries have now crossed the 10% wind and solar landmark, with seven new countries in 2021 alone: China, Japan, Mongolia, Viet Nam, Argentina, Hungary and El Salvador. Three countries—the Netherlands, Australia and Viet Nam—shifted over 8% of their total electricity demand from fossil fuels to wind and solar in just the last two years.
Meanwhile, coal power rose by 9.0% in 2021 to 10,042 TWh, a new all-time high and 2% above the previous record set in 2018. It was the biggest percentage rise on record since at least 1985, taking coal generation to 36% of global electricity.
New coal records were set throughout Asia in 2021, where electricity demand boomed, including in China (+9%), India (+11%), Kazakhstan (+6%), Mongolia (+13%), Pakistan (+8%), the Philippines (+8%) and most likely Indonesia (data not yet available). In 2021, coal power in the US, EU and Japan strongly rebounded compared to 2020, but remained below 2019 levels. China’s share of global coal power rose from 50% in 2019 to 54% in 2021.
