Initial estimates say cryptocurrency mining could account for up to 2.3 percent of total annual US electricity use.
In 2021, when China banned bitcoin and other cryptocurrencies, crypto miners flocked to the United States in search of cheap electricity and looser regulations. In a few short years, the U.S.’s share of global crypto mining operations grew from 3.5 percent to 38 percent, forming the world’s largest crypto mining industry.
The impacts of this shift have not gone unnoticed. From New York to Kentucky to Texas, crypto mining warehouses have vastly increased local electricity demand to power their 24/7 computing operations. Their power use has stressed local grids, raised electricity bills for nearby residents, and kept once-defunct fossil fuel plants running. Yet to date, no one knows exactly how much electricity the U.S. crypto mining industry uses.
That’s about to change as federal officials launch the first comprehensive effort to collect data on cryptocurrency mining’s energy use. This week, the U.S. Energy Information Administration, an energy statistics arm of the federal Department of Energy, is requiring 82 commercial crypto miners to report how much energy they’re consuming. It’s the first survey in a new program aiming to shed light on an opaque industry by leveraging the agency’s unique authority to mandate energy use disclosure from large companies.
“This is nonpartisan data that’s collected from the miners themselves that no one else has,” said Mandy DeRoche, deputy managing attorney in the clean energy program at the environmental law nonprofit Earthjustice. “Understanding this data is the first step to understanding what we can do next.”
Ok, but “the amount of electricity used by the State of Washington” isn’t exactly a reliable metric. Like… it’s not a quantity people can easily hold in their minds and compare to other things. To pretty much everyone, it’s meaningless without a rather large amount of contextualization. Even this silly article fails to enumerate how much power is being used, how much power Washington State produces, or what percentage of Washington State’s power supply is consumed by crypto mining. 
While I don't know the numbers, I'd guess that traditional financial systems all together probably are processing orders if magnitudes more transactions.
So while a pure total energy consumption comparison is one thing it would be interesting to conpare energy consumption on a few different factors:
total energy consumption
energy consumption per transaction
energy consumption per user
energy consumption per $ amount transacted
Not saying traditional finance would come out on top, I'm legitimately curious
Yes, and you hit a key component here. The amount of energy required to process transactions in bitcoin remains the same no matter how much it scales (this is algorithmically enforced by the hash difficulty).
One of the problems with banks is that, as their system scales, they have to burn immense amounts of carbon.
If we just scale down tradfi and switch to immutimle block chain ledgers, we would be eliminating the climate damaging effects caused by financial services companies without increasing the energy usage of cryptocurrency like bitcoin
Oh, and by biggest impact isn't on average people, but on industries that have money to invest in reducing their own costs. It'll probably make some products more expensive in the short term, but it'll also create jobs for people who can reduce carbon footprint, and the increased costs should be temporary as companies adjust to the tax.
A carbon tax is one of my top political priorities, perhaps second only to election reform.
