Norway generated about 99% of its electricity from renewable sources in 2022, according to the International Energy Agency.
Norway’s electricity system is dominated by hydropower. Mountainous terrain, heavy precipitation, and numerous lakes create favorable conditions for reservoirs and run-of-river stations. Hydropower supplies most of the country’s electricity, while wind power provides a smaller but growing share.
This statistic concerns electricity generation, not all energy used for transport, heating, and industry. Norway remains a major petroleum producer, so its renewable share of total energy consumption is much lower than its renewable share of electricity. That distinction matters when comparing national energy systems.
Norway’s reservoirs also provide flexibility: operators can store water and adjust generation as demand changes. Electricity can be traded with neighboring European countries through interconnectors. Sweden, Iceland, and Costa Rica also have very high renewable electricity shares, but their exact mixes and annual percentages differ.
