This isn't practical everywhere, but on the island of El Hierro (Canary Islands) there is a wind-and-battery solution in the form of a wind-pumped hydro-electric station. In effect there is a big pool of water acting as a battery and the wind turbine "charges" it.

When I ran across it on a trip to the island I was really impressed. Very original solution!

If it would be actually climate emergency then we would be building in mountains all where reasonable. No matter the damage to some rare species, panorama and tourism.

I first heard about pumped hydro back in 2007.
