Most renewable electricity came from hydroelectric power (68%), followed by photovoltaic (11%), wind and biomass, according to official figures released on Monday.
The share of electricity generation from so-called new renewable energy sources (solar, wind, biomass and smaller hydropower projects) increased from 10.3% in 2020 to 11.5% in 2021.
Most renewable energy was produced in Switzerland: for example 76% of all hydropower and 79% of new renewable energies.
The share of electricity from coal-fired power plants remained largely the same (1.87% in 2021 vs. 1.8% in 2020).
Electricity generation from domestic nuclear power plants fell from 19.9% in 2020 to 18.5% in 2021.
Since 2005, Swiss electricity suppliers have been legally obliged to disclose the origin and composition of the electricity they supply.
A similar system of proof of origin was also introduced for energy suppliers in neighboring countries. This means that from 2021 no electricity from unknown sources – so-called gray electricity – will be permitted in Switzerland.
