According to the International Energy Agency (IEA), in 2019, about 28% of the world's electricity generation came from renewable sources, of which about 18% was from hydropower, 9% was from wind and solar power, and 1% was from other sources such as geothermal and tidal power. However, electricity only accounts for about 20% of the world's total final energy consumption. The rest comes from other sectors such as transport, industry, heating, and cooling, which rely mostly on fossil fuels. Therefore, the share of green energy in the world's total final energy consumption is much lower than in electricity generation.
