Quotes “The freezing weather has rendered its 30,000 wind turbines to idleness. It is not just the wind turbines. Solar panels covered with snow are also rendered useless. . . . Instead, the solar and wind units are drawing power from the grid powered mainly by coal to keep their internal workings from freezing up." 

"The deadly winter is putting a strain on Germany’s Energiewende program and the country has to be rescued by, you guessed it, “dirty” fossil fuels. . . . The Germans have found that dependable, dispatchable coal can work in any weather and is the savior during these cold months."

“The guaranteed output of wind energy and photovoltaics [solar] is between zero, two or three percent. So de-facto is zero. . . As Germany moves to shut down its reliable nuclear and coal power plants, the gap between supply and demand will grow dangerously wide."

Yet the lesson-learned is very similar.  Over reliance on Wind & solar leads to power shortages and blackouts.  In the U.S. or elsewhere.   Another example occurred in Australia where wind power was blamed for a blackout in 2016 that cut supply to 850,000 homes.
