>Consider the case of a crypto mine being established in a remote and isolated location in the desert (or on the moon) with plenty of sunshine and solar power. As long as the mine has an internet connection, it can use the available solar energy to mine crypto and send them to anyone on earth. This physically results in the mine being able to transmit energy wirelessly across vast distances.
When the person wants to spend the crypto to get energy later, then new energy still has to be produced in addition to the energy used for mining (either by burning fossil fuels or using some of the capacity of renewables). If they're producing 100 units of energy to run their miner to get enough crypto to buy 100 units of energy later, then there's twice as much energy having to be produced than if they didn't run their miner.
Money is a tool for humans to allocate resources between themselves. It's not energy storage.
If there was only one person on Earth that could freely use any resources available to them, then they wouldn't ever have any use in "saving up energy" by crypto-mining to spend later because it's not saving up energy. It's making energy and spending it on IOU notes to trade to other people for energy they make. It's only when you add other people to the system that it makes any sense to do. Though ideally, the people would be able to coordinate together to come up with a solution that doesn't involve twice the energy being made with half of it going into making IOU notes.
