APS Sets Peak Energy Demand Record in Phoenix on 2025 Hottest Day

In 2025, U.S. power consumption is reaching record highs, with Arizona Public Service (APS) experiencing a new peak energy demand of 8,527 megawatts on the hottest day in Phoenix, reflecting rapid regional growth and increased electrical usage. APS plans to meet rising demand through significant ongoing investments exceeding $2 billion annually in grid upgrades and diverse energy resources, though it has requested a 14% rate increase that could raise residential bills by $20 monthly by 2026. Nationally, U.S. natural gas production rose by 4.7 billion cubic feet per day in the second quarter of 2025 compared to 2024, supporting increased energy needs. However, these trends coincide with a troubling global context highlighted at COP29, where fossil fuel carbon emissions hit a record 37.4 billion tonnes in 2024 despite international climate efforts, with coal use declining in the U.S. but rising in countries like India and China. The Energy Information Administration forecasts continued growth in U.S. electricity demand through 2026, underscoring the tension between energy consumption growth and climate change mitigation goals. These developments illustrate the challenge of balancing energy reliability, affordability, and environmental responsibility amid escalating climate impacts.
