Summary

Amid growing concerns over the impacts of climate change on worldwide water security, Bitcoin’s water footprint has rapidly escalated in recent years. The water footprint of Bitcoin in 2021 significantly increased by 166% compared with 2020, from 591.2 to 1,573.7 GL. The water footprint per transaction processed on the Bitcoin blockchain for those years amounted to 5,231 and 16,279 L, respectively. As of 2023, Bitcoin’s annual water footprint may equal 2,237 GL.

The estimated power demand of the Bitcoin network reached a new all-time high in March 2023,7 suggesting an annualized total electricity consumption of 141.9 terawatt-hours (TWh). This represents a 35% increase compared with the total estimated electricity consumption of 104.9 TWh in 2021 (Data S1, sheet 4). Consequently, the water footprint of Bitcoin may have increased by a similar magnitude. Assuming a constant water intensity of electricity consumption (15.76 L per kWh) since January 2022, 141.9 TWh of electrical energy consumption could result in a water footprint of 2,237 GL (Data S1, sheet 4). With the network handling 113 million transactions in 2020 and 96.7 million in 2021, the water footprint per transaction processed on the Bitcoin blockchain for those years amounted to 5,231 and 16,279 L, respectively.

the total water footprint of US Bitcoin miners could be equivalent to the average annual water consumption of around 300,000 US households, comparable with a city such as Washington, DC.

water use is such a weird thing to talk about like this because it's such a localized issue while the social ill of bitcoin fuckers are global.

if this is why somebody went from "bitcoin is fine" to "bitcoin is stupid af" i'd love to hear from them.

I've always felt bitcoin was stupid. I was laughing at the MTGOX fiasco like 15 years ago.

It's the more recent revelations about how incredibly wasteful it is that have me upgrading it from "stupid and should be ridiculed" to "evil and should be destroyed."

crypto is evil and should be destroyed regardless. it was designed to bring about an anarcho-capitalist dystopia, and it's enriched and empowered some of the most deranged psychopaths on the planet

a lot of cryptocurrencies such as Ethereum have switched to a proof-of-stake model which uses far less computational power and thus doesn't have the same environmental impact of bitcoin. this worries me because it will only make crypto more palatable to the liberal masses who only understand that it's bad for environmental reasons

we don't want the libertarian pedophile pyramid scheme to be carbon-neutral, we want to destroy the libertarian pedophile pyramid scheme

Good point. Let's build an actual pyramid and shove all the libertarian pedophile schemers into it and seal the tunnel with a giant stone that says "this is not a place of honor" etc etc.

I've thought it was stupid for a while now, but putting things as per transaction really feels different. Like, every time you buy something with bitcoin an entire ass pool is wasted. That's just crazy.
