Cost for wind and battery back up is cheaper than nuclear Similar for solar. So when people talk about the need for back up they don’t mention that the cost including back up is still cheaper than nuclear, which is cheaper than fossil fuels.
Even many regional message boards or forums we’re very active. Boards.ie in Ireland was the nerds internet forum. A fediverse before there was one. It was the go to for info about anything tech related or internet culture. Whirlpool in Australia is still the go to for info about internet and broadband, and is still active, if much reduced.
Is this in an imaginary world with no power from anywhere else, including international interchange? Total battery power is a society ending event. It’s hard to speculate on a power situation that doesn’t exist.
Costs are based on supply and demand. At current demand battery power back up is cheaper than non environmentally friendly forms of energy. Should that change due to supply issues, we can recalibrate.
Howevwrx the smart money, which happens to also benefit the environment, is on green energy.
Pumped storage is still great and has a plate but we need to consider the environmental effect of the dams and reservoirs too. Experimental usage of electric vehicles as a battery supply has also been positive.
