Overview
- Mayor Zohran Mamdani tweeted a request on July 1 that New Yorkers set air conditioners to 78°F and curb nonessential electricity use to ease stress on the city’s power grid.
- Prominent Republicans publicly mocked the guidance, with figures such as Nikki Haley, Senator Ted Cruz and Fox’s Jesse Watters criticizing the request as overreach.
- Reporters found the U.S. Department of Energy had recently published a page recommending daytime indoor temperatures of 75–78°F and that the page was taken down days after the mayor’s tweet.
- Conservative outlets used the episode to blame Mamdani and state climate policy for grid weakness, while the New York Post reported many municipal offices were kept cooler than 78°F and published opinion analysis linking policy choices to higher costs.
- Energy experts and past practice note 78°F requests are routine in heat waves, but the story exposed broader grid stresses — rising AC use, aging equipment and recent plant retirements — that make demand‑reduction appeals politically sensitive and could undermine public trust in future emergency guidance.
