Turbines

The recent power failure in Spain illustrates one of the problems with wind and solar. Spain and Portugal get about 80% of their power from wind and solar. In most countries the power comes from fossil fuels which means rotating turbines. When there is a glitch in the power system the turbines can speed up or slow down to compensate but with wind and solar there are no turbines. If they had been using small nuclear reactors for power this would not happen since these units use turbines.
