LindaG23 Looks like you still have power. Here’s an answer to your question the other day. “One of the weirdest aspects of this event is that Texas’s grid can withstand surges of power demand during the summer—even when the grid’s 26 million customers all want to run their air conditioners at once. Why can Texas’s grid hold up in the summer but not the winter? Joshua Rhodes, an energy scholar at the University of Texas at Austin, explains in a useful Forbes piece that electric cooling is an easier problem than heating, at least in Texas. In order to make a Texas dwelling comfortable and safe in 100-degree-Fahrenheit heat—say, to bring it to 70 degrees Fahrenheit—an AC unit must lower the indoor temperature by 30 degrees. But with overnight lows in Austin touching 10 degrees, heaters must now raise interior temperatures by 60 degrees to reach the same level. “Keep in mind,” he writes, “our homes are designed with insulation for a 30F differential and a preference for shedding heat, not a 60F differential with a desire to retain heat.”
