Generation Forecast (TWh)

Chart by Visualizer

Global electricity demand declined slightly in 2021 due to the Covid pandemic. It has rebounded slowly into 2023 and the growth is expected to accelerate going forward, primarily driven by renewables. Global generation reaches 29000 TWh in 2030 – up 25% from 2023.

China will account for a third of global electricity demand in 2030 and, combined with strong growth in other parts of Asia, this region will make up more than half of global electricity demand. Europe and North America will also grow steadily although their share of global demand will decline as Asia’s expands.

Incorrys forecasts solar generation to increase from 1250 TWh in 2022 to 7200 TWh in 2030 and will account for 24% of global electric generation.
