    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.

      Cost for wind and battery back up

      To supply germany for one week you need more than the world’s supply of batteries. It’s hard to speculate on the price of something that doesn’t exist.

      Pumped storage is currently the only technology that could make grid-scale power storage work.

        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.

          You are so right. Thank you! In a situation where it is impossible to generate or import any electricity at all, a nuclear reactor would not be able to produce any electricity either, because the grid is non-operational.
