Oh, come on. All of those things, except for travel, draw roughly zero watts compared to Bitcoin.
One Bitcoin transaction is about 750 kWh. That's enough to power a typical home for a month. It's enough to drive about 500 miles in an electric car, or (with vigorous handwaving based on EPA numbers) about 200 miles in an efficient gasoline car.
Bitcoin uses about 1/3 the energy of all the datacenters in the world. There are about 120 million Bitcoin transactions per year. If we assume 360 million people are using services that run in datacenters (obviously too low), one Bitcoin transaction uses as much electricity as the server time to support one user across all the services they use for a year.
>Being judgmental about how others use energy they pay for reeks of hypocrisy, virtue signaling and holier-than-thou attitude.
This is an engineering problem.
- bcheung 6y agoA transaction or a block? Multiple transactions are recorded in a single block. The massive computational power is used to certify and lock down blocks at a time, not individual transactions.
