A power outage left thousands of homes and businesses in New Orleans in the dark. The reality is that this power outage wasn’t an unfortunate coincidence, but a longstanding problem. Our reliance on volatile power-generation sources and years of delays in upgrading an outdated transmission grid has created a system where outages on sunny days will become even more common. Even though other regions had extra power, Louisiana couldn’t import it. With summer temperatures continuing to rise, local businesses can’t afford to be left in the dark again.
