As nation freezes, fossil fuels are keeping the lights and heat on By Stephen Moore, opinion contributor — 02/16/21 02:15 PM EST The views expressed by contributors are their own and not the view of The Hill https://thehill.com/opinion/energy-environment/539004-as-nation-freezes-fossil-fuels-are-keeping-the-lights-and-heat-on This story isn’t so much about the weather as it is about a grand failure of public policy. Because of the political left’s war on fossil fuels, and “renewable energy mandates” that require 20 percent to 30 percent of a state’s power supply to come from wind and solar power, the power grid is squeezed to the brink. Wind and solar don’t generate much power when temperatures plummet. The Center of the American Experiment, a Minnesota-based think tank, reports: “Wind turbines are shut down when temperatures are below -22° F because it is too cold to operate them safely. This means it will be too cold for the wind turbines built by the power companies to generate any electricity.”
