Some key insights from the article:
Basically, what they did was to look at how much batteries would be needed in a given area to provide constant power supply at least 97% of the time, and the calculate the costs of that solar+battery setup compared to coal and nuclear.
I would have loved that but having a wind turbine is… not easy. Permits, psychotic attitude from neighbours… but that have been my go-to given we don’t have a stream to go hydro. I’m still happy with covering 8 ou of 12 months with our setup but it’s still unnerving to swallow the costs of the setup + utilities for winter months…
Wind kinda has to go big for efficiency. It’s hard to beat the laws of physics on this. Not really feasible for individuals to do in a meaningful way unless you have a whole farm.
Solar panels are workable-ish. Residential rooftop is OK, but the real cost benefit is from filling big, flat fields with racks. Homes have to be a boutique setup every time, and labor cost adds up.
If you want to be (semi-) independent of traditional power utilities, the way to go is co-ops. You and all your neighbors go in on buying a field and putting solar/wind/storage on it
Residential wind for electricity generation is not really recommendable afaik, but it could be viable for some amount of heat generation, potentially: https://solar.lowtechmagazine.com/2019/02/heat-your-house-with-a-mechanical-windmill/
