Texas has made a massive investment in wind power, and the turbines are starting to move. 18,000 megawatts (MW) of wind generation capacity are already up and running, and 5,500 more are coming soon. But there’s a problem: It’s hard to build the infrastructure to get all that energy to people. There’s a serious possibility that turbines will have to be turned off at times to keep from overloading the system.
