"Set your AC to 78 degrees, turn off lights/electronics you're not using, and unplug what you can," New York City Socialist Mayor Zohran Mamdani wrote on X late Wednesday.New Yorkers are now getting a real-world lesson in what Mamdani's recent "warmth of collectivism" comments actually mean: shared sacrifice, including being told to dial back air conditioning during blistering heat as the risk of power blackouts rises.New York: it's hot out there, and the power grid is working overtime to keep us cool.

PJM expects to break its all-time peak load record of 165.5 gigawatts later today.
