"Wind/solar are intermittent and there's no way around that (battery storage isn't nearly mature enough)" One way 'around that' is to use gravity storage -- of which dozens of examples already exist around the world. China has at least 21 pumped-hydro facilities (19GW capacity [0], working on 30GW more [1]) and Britain's been using one for 'tea-time' demands for decades. 'Waiting for batteries' is decisively not a useful argument. They're very far from the most economical and environmentally-friendly storage.
