Mamdanis AC warning revealed that NYs power grid is in big trouble and its a problem he helped cause

As temperatures hit 100 degrees last week, New York City’s unconventional mayor did something pretty conventional: He urged people to use less electricity.But when Mayor Zohran Mamdani urged residents to set their air conditioners to 78 degrees (a past practice of both Democrats and Republicans alike), he revealed something far more harmful than the heat index: how much Albany’s policies have driven New York City’s power grid to the point of collapse.Several factors are at play every summer.About 90% of homes today have air conditioning; as recently as the 1980s, most didn’t.Portions of the electric system are extremely old by national standards, and the sheer physics of generating and distributing the appropriate voltage and amperage to every corner of such a dense and diverse cityscape borders on the miraculous.Tighter ozone-emission rules began taking effect in 2023, forcing about a dozen of the city’s smaller power plants to close — making it even tougher to get juice to every corner.Recall that the city nearly had rolling blackouts a year ago, as temperatures spiked and older plants broke down in the heat.That’s why, as far back as the 1990s, mayors have made public appeals on the hottest summer days asking New Yorkers to set thermostats to 78 degrees.Rudy Giuliani, hardly an “ecosocialist,” did it.So did Mike Bloomberg, and Bill de Blasio, and Eric Adams.To be sure, 78 isn’t an especially comfortable temperature in a withering heat wave, and the actual benefit for the grid is tiny.And, as The Post reported, Mamdani’s City Hall didn’t exactly lead by example.Fifteen out of 20 spots in municipal office buildings were found to be maintaining much cooler, and much more bearable, temperatures.Critics were right to mock Mamdani’s hypocrisy.But what they missed is that his call inadvertently revealed a problem he himself helped cause: the frightening weakness of NYC’s electric grid — a weakness that makes a 78-degree floor an urgent dem...
