Source: Ember, Global Electricity Review 2026 (April 21, 2026).
Ember, "Global Electricity Review 2026" (published April 21, 2026; we read it on October 24, 2026). Coal 33.0% (10,476 TWh), gas 21.8% (6,919 TWh), hydro 14.0% (4,437 TWh), nuclear 8.9% (2,812 TWh), solar 8.7% (2,778 TWh) and wind 8.5% (2,715 TWh) are Ember's shares of global generation in 2025. Ember's total for renewables is 33.8% (10,730 TWh).
Note: Ember does not list two of the eight slices. "Bioenergy and other renewables" (2.5%) is what is left of Ember's 33.8% renewables total after hydro, solar and wind, and "Other fossil" (2.6%) is what is left of its 57.4% fossil total after coal and gas. Both are our subtraction, not Ember rows. The shares are rounded, so the slices add up to 100.0% while Ember's own totals can differ from a sum of rounded rows by 0.1.
Ember reports renewables at 33.8% (10,730 TWh) against coal at 33.0% (10,476 TWh). In a pie chart that is the one comparison that changed: the two biggest groups are nearly the same size, so the slices have to be added up by type to see it.
Hydro was 14.0% of the world's electricity. Solar (8.7%) and wind (8.5%) are each smaller, but together they make 17.2%, more than hydro, and Ember reports that wind and solar now make more than half of all renewable generation.
Gas reached a record 6,919 TWh and 21.8% of generation, the only fossil fuel that increased in 2025 according to Ember, while coal fell by 63 TWh. Fossil fuels together were 57.4%.
Of 17,002 charts downloaded from this site between January 29 and October 23, 2026, 78.3% had six slices or fewer and only 4.3% had exactly 8. To match that, make a three-slice version by type: fossil fuels 57.4%, renewables 33.8% and nuclear 8.9%.
