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 you live where sun is abundant all year round… In which case (Las Vegas?) I would question the choice of having humans living in a fucking desert in the first place. But man I wish I could cover my needs between October and March here in Europe but no battery will help me store so much for so long :-/
Does the wind blow year round? I’m imagining a similar case for wind, then you can say that for the union of these two sets, renewables are cheaper than legacy energy
Maybe bump that number slightly for places with hydro that can serve as a battery
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…
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/
