Coal remains the world’s leading source of electricity generation in 2025, underscoring the continued reliance on fossil fuels even as renewable energy expands at a rapid pace.
According to recent data, coal accounts for 32.97% of global electricity production, maintaining its position at the top of the energy mix. Natural gas follows with a 21.77% share, reinforcing the dominance of hydrocarbons in power generation worldwide.
Among cleaner energy sources, hydropower contributes about 14% of total output, while nuclear energy makes up 8.85%. Solar and wind energy are close behind, representing 8.7% and 8.5% respectively, figures that highlight their growing role in the global energy transition.
Total electricity generation reached approximately 31,779 terawatt-hours in 2025. Despite strong growth in renewables, fossil fuels still account for about 57% of global production, compared to 43% from clean energy sources.
The data reflects a complex transition landscape: while investment in renewables continues to accelerate, entrenched infrastructure and energy demand, particularly in emerging economies, are sustaining the prominence of coal and gas in the global power mix.
