Solar thermal energy - statistics & facts
Approximately 13 percent of the global heat supply came from renewable energy sources in 2022. This is considerably lower than the share of renewables in electricity generation, which stood at roughly 30 percent in that same year. Solar thermal energy, which uses solar radiation to heat a fluid, produces direct heat for domestic and industrial applications and plays an important role in the decarbonization of heat production. In 2022, the share of solar in the consumption of renewable heat worldwide stood at 5.4 percent, behind the use of bioenergy, renewable electricity, and heat pumps.
