America's power grid is not ready. ✉️ Sign up for our newsletter: http://www.vox.com/video-newsletter In February, extreme cold and an unusual winter storm left millions of Texans in the dark. Many went without power or water, in subzero temperatures, for nearly five days. It was a disaster; dozens died. But even though that storm hit much of the country, the power outages were mostly limited to Texas. That’s because Texas is on its own electrical grid, separate from the rest of the country, which means it can’t easily get power from other states in an emergency. But Texas's grid itself is not what failed. Power went out across Texas in the first place because energy sources across the state were unprepared for severe weather. And that didn’t have to happen; Texas had been warned about this exact scenario, and had actually experienced versions of it twice in the last 30 years. But they didn’t prepare. Now the rest of the US faces the same issue. Climate change is making severe weather disasters more and more frequent. And the American energy system is not ready for it.
