Martin SeegerIf you do 12 Bitcoin transactions per year, you use a higher amount of energy than we use for a complete family (including: heating, warm water, electricity, car charging) in the same year. We do all via electricity.

I just read that a single Bitcoin transaction requires upwards of 1,000 kW-hr of electricity. That’s like running a small air conditioner 24/7 for a month and a half. Edit: This got way more attention than I expected from an offhand remark; I guess it hit a nerve on here! But I’m going to have to mute this, as it’s taken over my notifications...
