Isn't that why we're experimenting with mechanical energy storage like pulling train cars full of rocks or pumping water uphill?

Problem is that the amount of energy storage we need to convert 100% to renewables is enormous. Pumped hydro works just fine but takes a massive amount of area and the right topography. Compressed underground air storage also works, but is geology-specific.

The right answer is a blend of wind, solar, and nuclear fission, but there's still a ton of (mostly ignorant) folks against nuclear power.
