The latest Monthly Electricity Statistics published by the International Energy Agency show that in January 2025, total net electricity generation in the OECD member states reached 1015.1 TWh, an increase of 2.9% compared to January 2024. Of this total, 495.4 TWh (48.8%) was produced from fossil fuels, 342.8 TWh (33.8%) from renewable sources and 172.5 TWh (17.0%) from nuclear power.
Electricity generation from fossil fuels increased by 0.9% year-on-year in the OECD in January 2025. Electricity generation from natural gas increased 1.1% year-on-year (+3.3 TWh), while generation from coal remained the same year-on-year. The shares of natural gas, coal and oil as a percentage of the total were 29.1%, 17.9% and 1.3%, respectively. The increase in electricity generation from natural gas was driven by OECD Europe (+14.5% y-o-y, +8.3 TWh), while gas fired generation fell in the Americas (-2.4% y-o-y, -4.4 TWh) and in Asia Oceania (-1.4% y-o-y, -0.7 TWh).
Generation from renewable sources increased by 4.2% year-on-year (+13.9 TWh) in January 2025. The highest absolute increase came from solar generation (+29.5% y-o-y, +11.7 TWh), bringing total OECD solar generation to 51.1 TWh (5.0% of the total). This was driven by the Americas, where solar increased by 49.0% year-on-year (+7.9 TWh) to 23.9 TWh. In Europe, solar generation increased 20.7% year-on-year (+2.1 TWh) to 12.3 TWh. Notable increases were also seen in Türkiye and Spain, with solar generation increasing by 0.9 TWh and 0.4 TWh year-on-year, respectively. In Asia Oceania, solar generation increased 12.7% year-on-year (+1.7 TWh), driven mainly by Australia (+26.5% y-o-y, +1.3 TWh).
Wind power increased 3.8% year-on-year (+4.5 TWh), bringing total wind generation to 121.9 TWh (12.0% of total generation). But hydropower generation in the OECD decreased by 2.7% year-on-year (-3.8 TWh) to 135.2 TWh (13.3% of total generation). Hydropower generation in OECD Europe decreased 9.9% year-on-year (-6.2 TWh).
The nuclear power component increased 6.5% year-on-year (+10.5 TWh) in the OECD in January 2025. Asia Oceania registered the highest absolute increase of 4.7 TWh year-on-year (+22.7%), driven mainly by nuclear power generation in Korea increasing 2.8 TWh year-on-year (+19.6%). Nuclear power production in OECD Europe and the Americas increased 4.8% (+3.0 TWh) and 3.5% (+2.7 TWh) year-on-year, respectively.
A standout increase was seen in Canada, where in January electricity generation from wind increased 29.9% (+1.2 TWh) year-on-year to 5.2 TWh, 7.9% of total generation. Several projects increased Canada’s wind capacity in 2024, including the Buffalo Plains wind farm (494 MW) in Alberta, which began operations late last year and is now Canada’s largest onshore wind farm.
