This is the surprising story of how Texas – rich in oil and gas – became America's biggest producer of wind energy. For our first episode, Ryan and Anjali talk with Pat Wood, once George W. Bush’s right hand man and head of Texas's Public Utility Commission, to uncover the innovative approach that turned Texas into a renewable energy powerhouse. It’s a story about what could get done before partisan politics got in the way of good climate policy, and it shows that economic incentives for consumers, government, and companies can play a huge role in supercharging clean energy.
