Minnesota-based Xcel Energy made a surprising announcement this week — it’s shutting down its coal-fired power plants in Minnesota by 2030.

The state’s largest power company is switching to renewable energy at a time when President Donald Trump bashes energy sources like wind. It is hard to understand why Trump mocks wind power, one of the fastest job-growing industries in the country.

At a Conservative Political Action Committee convention in March, and during a number of other public appearances, the President claimed wind-powered energy won’t be delivered if the wind is calm.
