Texas is getting increasing amounts of power from wind. But a cold front stopped the wind, traditional power plants failed to make up the difference, and blackout nearly happened.
That’s why storage of unused power and interconnected grids of renewable energy are increasingly important. Solar can store heat in molten salt to create power at night, and wind can create hydrogen that can be stored. We will see more of this as renewables go mainstream.
There we go, the more dependent we are on these sources, the more we’ll see the drawbacks. You’d assume though that someone would have thought this scenario out and prevented it from happening.
