One method was to use gravity batteries. Basically you use solar/wind energy to pump water upwards and when you need the power, you release the water and gravity turns a turbine.

Obviously this becomes impossible if your grid is at capacity.

Plus, all the hippies tend to forget what needs to happen to make hydro power in the first place. You need to skullfuck an entire ecosystem to build a massive fuckoff dam.

I mean, once you've utterly destroyed an entire region sure, the energy it produces is pretty green. Not as green as the valleys and forests you destroyed to make it.
