The two pie charts illustrate the proportions of total world energy consumption and electricity generation for the previous year. Overall, fossil fuels make up the largest share of global energy use, while electricity production relies most heavily on coal, hydro power, and nuclear energy.
Oil represents the biggest portion of total energy consumption at 34.3%, yet it contributes only a very small proportion to global electricity production. In contrast, coal plays a much more important role in electricity generation: although it accounts for 25.1% of energy consumption, it produces 39.8% of the world’s electricity. Gas shows a similar contribution to both categories, making up 20.9% of global energy use and 19.6% of electricity production.
Among the non-fossil fuel sources, nuclear power generates 16.1% of the world’s electricity but accounts for only 10.6% of total energy consumption. Hydroelectric power also has a slightly larger share in electricity generation (15.7%) compared with its smaller portion in total energy use (6.5%). Other sources contribute minimally in both charts.
