This document analyzes data on global electricity production by source from 1965 to 2018. It finds that around the world over 230 terawatt-hours of electricity was produced from coal, but less than 10 terawatt-hours was produced from wind, solar, and other renewables. Developing countries rely more heavily on sources like hydro and coal, producing over 50% of their electricity from these, while Europe and North America produce around 20% from nuclear power. Asia specifically relies on fossil fuels for over 50% of its electricity production. The trend is for renewable energy sources to increase their contribution to the global energy mix in recent years.
