And what does that have to do with power shortages? Answer: Wind & solar power is highly variable and bad weather causes numerable problems such as what Texas is currently experiencing https://www.telegraph.co.uk/us/comment/2024/01/16/green-wind-solar-energy-freezing-texas-power-grid-blackout/ Only Nuclear and fossil-fueled (gas of course - not coal) power plants are able to run regardless of weather (and at night). Sorry Greenies but your unrealistic goals of zero-emissions for the world just cannot work. Reality can be a bitch eh?
Considering the massive mining farms located mainly in Texas and a few in other areas of the US like Nebraska and Montana - all of whom have agreements with their power providers to cut back their mining when power is needed elsewhere in the state - of course the hash rate is way down.
Regarding renewable energy and BTC mining, I believe it's a good combo, since ASICs don't have to run 24/7/365. It's not an industry that produces cars/food or something like that...
You could have solar-powered ASICs dispersed all over the world and they would work only during the day. Not a big deal, since there's always a certain place that has day, while others have night. Hashrate would fluctuate a bit of course, but BTC can handle it.
Wind mills also tend to provide plenty of electricity during the night, so that's another alternative to keep the ASICs running during night hours.
