Energy is the power that allows you to take accion, to move around and to interact with your enviroment. In this sense, food, oil, speed, or height are either energy or can be transformed into it.

Same with money. But there is good money like bitcoin and bad money like the Venezuelan bolivar. Bitcoin not only stores energy, it also increases its value so you can do more things with it like feeding your family, start a business, etc. Bad money is a very poor store of energy and people starve to death because of that.

As for pure energy, like in KWH or Joules, power plants often produce an excess of energy for which there is no use. That energy gets lost forever. Now, by setting miners near power stations this energy is capture by bitcoin and is transformed into monetary energy. In that sense, BTC is a battery.

If you have money in your pocket, you can buy fuel and that fuel runs your car so it could be argued that money is stored energy in your pocket, hence a battery.
