> This is simply not true. There is no such thing as excess power, whatever is not used should be stored or sold to other countries. I agree that would be ideal, but current battery technology is limited and we loose power with transmission distance. A gravity battery could work for storing that excess power (up to a point) but that seems like it could be a pretty capital intensive project. In lieu of better solutions, we sometimes have to go with less than ideal ones. https://en.wikipedia.org/wiki/Gravity_battery https://en.wikipedia.org/wiki/Gravity_battery
