To be fair, one of the main uses for energy is heating/cooling our home. The house can act as a thermal battery, and many people already do so with heavy thermal insulation. (Heat up during the day and stay warm through the night, or vice-verse) Another part is transportation. Batteries can not progress infinitely, the best you can get is gasoline level, and then it is basically gasoline. I’m actually surprised that LiPo batteries are used in cars at all, due to how dangerous they are. There should be a transition away from cars to trains+bikes combination. Sadly people are too car-centric to make the shift.
