I have a modest set of solar panels on an entirely ordinary house in suburban London. On average they generate about 3,800kWh per year. We also use about 3,800kWh of electricity each year. Obviously, we can't use all the power produced over summer and we need to buy power in winter. So here's my question: How big a battery would we need in order to be completely self-sufficient? Background …
Do some quick math. How much pumped hydro in terms of acre-feet would be required to power a hypothetical city like Chicago at night? Where would this theoretical reservoir be built?
I guess if you don’t understand units of water per area, then there is no reason to expect you to be able to do any kind of critical analysis about why “pumped hydro” is a problem.
Dude, people can laugh at a term while still being able to do “critical analysis” 🙄 “foot pound” sounds funny too. People can giggle about Uranus and still be astronomers.
It isn’t so much limited by the geography but is made far more cost effective because of it. A long valley with a narrow exit means you don’t need to build much dam and store a vast amount of water.
As far as distance from populated areas, I dunno, I live in the UK so its kinda close enough not to matter too much.
Pumped hydro exists.

I can’t stop laughing at this as a unit of measurement
It’s easier to visualize than 325 kilo-gallons.

I am not American, so why would I use an American unit of measurement?
You can use whatever moon-units you want. I prefer to use people-centric units.
Ok, if you want an approximate American unit equivalent to a megalitre think of it as cube that can fit a blue whale

But is extremely limited to specific areas with the right geography that are also relatively close to a population centre.
