Current and projected total global electricity generation, measured in thousand terawatt hours (TWh). Sources included in the total global electricity generation are hydropower, nuclear, natural gas, coal, wind, and solar power.
The International Energy Agency's Stated Policies Scenario (STEPS) models the future of the global energy system based on existing policies and those currently in development. STEPS is considered a more conservative model than those based on announced pledges and targets. Totals include electricity generated from solar photovoltaics, wind, coal, natural gas, nuclear, and hydropower.
