Arizona

Arizona has abundant non-fossil fuel energy resources, ranking among the top five states for solar-powered generation. The state is home to one of the largest nuclear power plants — and third largest power plant of any kind — in the country, with 37% of in-state electricity generation from nuclear, alongside 25% from renewables and just under 40% from natural gas and coal. Net emissions increased 21% from 1990-2021, with only the electricity generation and agricultural sectors decreasing emissions. More than a quarter of Arizona’s land is held by tribes — the largest share in any state — and almost all of the state’s energy mineral resources are on tribal lands.
