Global electricity demand will rebound strongly in 2021 and 2022. After falling by around 1% in 2020, global electricity demand is set to grow by close to 5% in 2021 and by 4% in 2022. The majority of these increases will take place in the Asia Pacific region. More than half of global growth in 2022 will occur in the People’s Republic of China (hereafter, “China”), the world’s largest electricity consumer. India, the third-largest consumer, will account for 9% of global growth.

Renewable electricity generation continues to grow strongly – but cannot keep up with increasing demand. After expanding by 7% in 2020, electricity generation from renewables is forecast to increase by 8% in 2021 and by more than 6% in 2022. Despite these rapid increases, renewables are expected to be able to serve only around half of the projected growth in global demand in 2021 and 2022. Nuclear power generation will grow by around 1% in 2021 and by 2% in 2022.

Fossil fuel-based electricity is set to cover 45% of additional demand in 2021 and 40% in 2022. Coal-fired electricity generation, after declining by 4.6% in 2020, will increase by almost 5% in 2021 to exceed pre-pandemic levels. It will grow by a further 3% in 2022 and could set an all-time high. After declining by 2% in 2020, gas-fired generation is expected to increase by 1% in 2021 and by close to 2% in 2022. Gas growth lags behind coal, as it plays a smaller role in the fast-growing Asia Pacific region, and as it faces increasing competition from renewables in the United States and Europe.

CO 2 emissions from the electricity sector are set to increase in 2021 and 2022. After falling by 1% in 2019 and by 3.5% in 2020, CO 2 emissions from the electricity sector are forecast to increase by 3.5% in 2021 and by 2.5% in 2022, which would take them to an all- time high. The decline in the emissions intensity of global electricity generation slows from more than 3% in 2020 to around 1% in 2021 and 2022.

Stronger policy actions are needed to reach climate goals. In the IEA Net‐Zero Emissions by 2050 Scenario, nearly three- quarters of emissions reductions between 2020 and 2025 take place in the power sector, where emissions decline by 4.4% per year on average. To achieve this decline, coal-fired electricity generation needs to fall by more than 6% a year, partially replaced by gas, which grows by around 5% a year.

Wholesale electricity prices have recovered. The IEA Wholesale Electricity Market Price Index, which tracks price movements in major advanced economies, shows that prices were 54% higher in the first half of 2021 compared with the same period in 2020. This is after average prices for the full year 2020 declined by 25% compared with 2019. The reasons for these large swings are strong
