About water storage, specifically, an old school wind-powered water pump to lift well water into a holding tank (like you'd see out in the West of the US before and just after the turn of the least century) would be a really good use of wind power to provide a good way to lift water and greatly reduce pumping power required to maintain good pressure in your water system, mostly passively. (You'd need to maintain the windmill occasionally and make sure the system isn't leaking, but... Some of those setups are still functional after nearly a century with minimal maintenance, which is one of the things that I consider when pondering what to do as I build my home.)
