This executive summary from Ember reports that while wind and solar energy reached a record 10.3% of global electricity generation in 2021, global electricity demand grew faster than clean energy could keep up with. This resulted in record-high coal generation and CO2 emissions from the power sector in 2021, driven largely by demand increases in Asia.

  • Wind and solar energy reached a historic milestone in 2021, accounting for 10.3% of global electricity generation, up from 9.3% in 2020 and 4.6% in 2015. Combined clean energy sources generated 38% of global electricity in 2021, surpassing coal's share of 36%. Fifty countries now generate more than 10% of their electricity from wind and solar, with seven new countries reaching this threshold in 2021: China, Japan, Mongolia, Vietnam, Argentina, Hungary, and El Salvador.
  • Global electricity demand saw its largest absolute increase ever between 2020 and 2021, rising by 1,414 TWh (+5.4%). This growth was primarily driven by Asia, with China experiencing a 13% increase in demand in 2021 compared to 2019. Because wind and solar only met 29% of this demand increase and other clean sources like nuclear and hydro remained stagnant, fossil fuels filled the gap.
  • Coal generation hit a new all-time high in 2021, increasing by 9.0% to 10,042 TWh, which represents 36% of global electricity. This growth was widespread across Asia, including China (+9%), India (+11%), Indonesia, Kazakhstan (+6%), Mongolia (+13%), Pakistan (+8%), and the Philippines (+8%). China's share of global coal-generated power rose from 50% in 2019 to 54% in 2021.
  • CO2 emissions from the power sector reached a record high in 2021, increasing by 7% to 778 million tonnes. This is the largest percentage increase since 2010 and the largest absolute increase in history, indicating that emissions are now higher than they were before the pandemic.
  • To align with a 1.5 °C warming limit, wind and solar energy must maintain a combined annual growth rate of 20% until 2030, which matches their average growth rate over the last decade.
