The Best Battery Technology, Nature's Battery

The best battery technology, nature's battery, is hydrocarbons. In a couple of centuries, we've built enormous distribution lines for processing them and producing them. This ability to be available on demand, high power on demand is something that is what makes fossil fuels so valuable. So there's no question in my mind that Bitcoin is more consuming of energy than central banks when you just look at central banks in isolation. But if you really want to compare energy expenditure, you want to include the energy expenditure that goes on more because A, fiat money allows financing of war; B, monetary system doesn't operate without government funding.
