Mapped: Zero-carbon power across North America
The highest and lower share of zero-carbon power by state and province
North America is home to some of the most diverse low-carbon power portfolios in the world.
Canada leads, with over 80% of its electricity from zero-carbon sources. Hydropower dominates in provinces like British Columbia, Quebec, and Manitoba, while Ontario combines nuclear and hydro for a clean, baseload-heavy grid.
The US has a more varied mix, with ~40% of U.S. electricity in 2024 coming from low-carbon sources. Nuclear has held a steady share around 18–20%, with hydro, wind, and solar each contributing significantly. Growth is strongest in solar, especially in California, Texas, and the Southeast, while wind leads in the central corridor, from Texas up through Iowa and the Dakotas.
Across the continent, the trend is clear: the power mix is tilting toward renewables and nuclear power. But challenges remain, including the grid connections, permitting delays, aging infrastructure and the need for firm power to ensure reliability.
