It is wasted money.
I wouldn’t go so far as to call it waste. It’s an inherent problem of any energy storage, and we need energy storage if we want to go all in on renewables. Storage has to pay for the energy it stores and can only sell that energy for profit if there is enough demand on the grid, so it sits idle for a lot of time, but you still have the building and maintenance costs.
Probably not, because Israel is a full member of CERN, Russia was only an observer.
