Profile Overview
Quick Facts
- Arizona's Palo Verde Nuclear Generating Station is the second-largest nuclear power plant in the nation. In 2024, it accounted for 4% of the nation's nuclear generation and 27% of Arizona's total net generation from all sources.
- Arizona ranks among the top five states in the nation in total solar-powered generating capacity from both utility- and small-scale installations, with nearly 9,000 megawatts.
- Per capita energy consumption in Arizona is less than almost four-fifths of the states. This is partly due to the mild winter climate, which draws many seasonal residents, with almost 1 in 20 Arizona homes occupied only part of the year.
- In 2024, Arizona's total in-state electricity was generated mainly from 6 sources: natural gas (45%), nuclear power (27%), solar energy (13%), coal (8%), hydroelectric power (4%), and wind (2%).
- Arizona has major uranium reserves, including the highest-grade uranium in the nation. After years of no uranium mining in the state, mining resumed at the Pinyon Plain Mine in 2024.
