In February, an unusual winter storm left millions of Texans without electric power or water in subzero temperatures for nearly five days. Oklahoma and other neighboring states only had minor disruptions. Why? Texas is on its own electrical grid, separate from the rest of the country, unlike other states, so it can’t get power from other states in an emergency. Texas hasn’t upgraded its electrical infrastructure since its last big failure ten years ago, but most of the U.S. power infrastructure has aged beyond its “use by” date.
