U.S. Heat Wave Guidance and New Mexico’s Renewable Power Shift

Experts note that there is no single thermostat setting that works for every household during a heat wave. Recommendations to keep indoor temperatures at 78 °F (25.6 °C) are a starting point, but comfort and safety depend on factors such as home size, insulation, personal health and the efficiency of cooling equipment. Adjustments of one degree at a time, monitoring for heat‑stress symptoms, and complementary low‑cost measures can help balance comfort with energy costs.

In New Mexico, the electricity mix has moved from a fossil‑fuel majority to a renewable majority within five years, driven by the state’s Energy Transition Act. The Public Service Company of New Mexico now sources around 41 % of its summer generation from grid‑scale solar, supplemented by utility‑scale batteries that store daytime solar output for evening use, and increasing wind capacity. A major coal plant has been retired, and electricity prices remain below the national average despite the higher renewable share.
