Recent analysis by the Pew Research Center, based on data from energy research organization Ember, confirms that hydrocarbons remain the dominant source of global electricity generation. Coal, gas, and oil together accounted for 57% of worldwide electricity production, though this figure represents a notable decrease from 65% two decades earlier. The findings align with the Energy Institute’s Statistical Review of World Energy, which presents a comparable picture of the current global energy landscape.
Alternative energy sources have experienced significant growth in recent years. Wind and solar energy combined to produce 17% of the world’s electricity last year, a substantial increase from less than 5% a decade prior. When accounting for other renewable sources including hydropower, geothermal, and tidal power, renewables generated a larger share of global electricity than fossil fuels. Nuclear power, however, has declined considerably, falling from 17% of global generation in 2000 to 9% last year.
A key factor sustaining fossil fuel dominance is the disparity between electricity demand growth and the expansion of renewable generation capacity. Global energy demand is rising faster than new generation facilities can be constructed and deployed. Fossil fuels maintain their position partly because they can respond to immediate power demands, unlike renewables that depend on weather conditions. Though hydrocarbons’ share of the total electricity mix has decreased, their absolute consumption continues to increase due to surging worldwide electricity demand.
Geographic patterns in energy transitions vary considerably. China has achieved significant progress in renewable capacity deployment, becoming the world’s largest market for wind and solar installations. However, China simultaneously remains the globe’s largest coal consumer and continues constructing new coal-fired power plants. The European Union presents a contrasting approach, with non-hydrocarbon sources generating 48% of electricity last year compared to 29% from coal and gas plants, representing a more pronounced shift away from fossil fuels.
