Ethereum is green

The unit of energy we’ll use in this post is the kilowatt-hour (kWh). This quantity is called “one unit” on electricity bills, and it costs a domestic user about 12 cents in the US.

A 10,000 mAh power bank is able to run 10 validators (including Geth + Rocket Pool) on a Raspberry Pi for 10 hours.

The Pi consumes 5 watts, so that comes to around 0.1 KWh’s of energy per day for 10 validators, or 0.01KWh per validator.

That 3600x more energy efficient than Bitcoin PoW, or, put another way, a 99.97% reduction in power.

    That 3600x more energy efficient

    Does that make it 1x as efficient as a gtx 3600? JK, but seriously, is eth worth mining at home?

      probably not, especially compared to the 8% apy you will get from validating. After the merge (pure pos) apy will be higher (10-12%). Validating at home is not to hard to setup as well, you can do it on a raspberry-pi as in the article (though its recommend to have beefier hardware)
