Germany built one of the largest wind and solar fleets on Earth. It dismantled its nuclear power stations and retired its coal, with the promise that green energy would power its future. The country spent billions transitioning. Then winter arrived, and "Dunkelflaute" hit - the dark windless dead zone. Wind and solar fell to barely 5% of demand. The grid staggered. And Germany was forced to fire up old coal plants it said had closed forever, and import expensive nuclear from France. This is the physics politicians fail to mention, and a point many people still fail to grasp. When the wind dies and the sun sets, renewables disappear. And the only way the grid survives, the only reason countless millions don't freeze to death, is thanks to oil, coal, nuclear and gas.
