From July 2025 through June 2026, Arizona’s electricity consumption was supplied by roughly equal shares of low-carbon and fossil electricity: about 51% was low-carbon, while about 49% came from fossil fuels. Gas was the largest individual source, supplying about 43%, followed by nuclear at roughly a quarter and solar at almost a fifth. Solar included utility-scale generation at about 14% and behind-the-meter systems, such as rooftop installations, at about 5%. Hydropower contributed around 4% and wind around 3%, while coal supplied about 7%. Nuclear and solar therefore provided the backbone of Arizona’s clean electricity supply, although fossil fuels still accounted for nearly half, with associated climate and air-pollution impacts.

Is Electricity Growing in Arizona?

Arizona’s electricity consumption is growing, but only slightly on a per-person basis. The latest 2026 figure reached about 16,100 kWh per person, exceeding the previous record of roughly 16,020 kWh in 2024 by 81 kWh, or about 0.5%. Low-carbon electricity generation showed stronger progress, reaching approximately 8,250 kWh per person—about 294 kWh, or nearly 4%, above the 2025 record. These new highs are encouraging, particularly the faster growth in clean electricity. However, per-person figures alone do not establish the change in total statewide consumption, and sustained expansion will be important to meet demand from electrification and AI.

Suggestions

Arizona should build on its substantial nuclear and solar generation by expanding existing nuclear capacity where feasible and accelerating utility-scale and rooftop solar deployment. Nearby examples offer useful benchmarks: the US states of Nevada and California generate about 35% and 31% of their electricity from solar, respectively, compared with Arizona’s roughly 19%. For nuclear, the US state of South Carolina generates more than half of its electricity from this clean source, while France reaches about two-thirds, illustrating nuclear’s potential contribution. Wind can complement these technologies: the neighboring US state of New Mexico generates about 36% of its electricity from wind, and Colorado about 27%. Learning from these regions could help Arizona expand its low-carbon electricity supply and reduce fossil-fuel dependence.

History

Across the supplied 2024–2026 history, Arizona recorded several notable additions to low-carbon electricity generation. In 2024, nuclear generation increased by 0.9 TWh and wind by 0.8 TWh. Wind then continued growing, adding 0.6 TWh in 2025 and 0.2 TWh in 2026—a cumulative increase of 1.6 TWh across the three years. Hydropower fell by 0.7 TWh in 2024 and another 0.4 TWh in 2025 before recovering by 0.2 TWh in 2026. Low-carbon biofuel generation showed no year-to-year change throughout this period. The sustained wind gains are welcome, and further expansion of nuclear and solar would help Arizona maintain stronger growth in clean electricity.
