I feel like it's really easy to pin bitcoin on its energy usage just because it's so easily measurable. Is there any research that compares a traditional banking platform in terms of W/tx in comparison to bitcoin?
You don't need detailed research because a little back-of-the-napkin math shows that it's way too much. A comparison I found recently is that Bitcoin uses 10x as much electricity as Google. Why is this? Well, you can think of Bitcoin as giving away prize money to miners who win a contest. Currently they are giving away over $50 million in Bitcoin every day. [1] The electricity spend by miners is capped by the amount…
That doesn't really fix it, because transaction fees will start to dominate the block subsidy within 4 halvings or so.
