    I’ve always found this argument against crypto to be a bad one. The headline will say something like “Crypto mining uses XYZ total energy” and we’re supposed to infer that this means crypto is polluting a lot. But it doesn’t say how much pollution there actually was. For economic reasons, these miners often use cheap excess energy that would have been produced anyway or green tech. Not all of it obviously, but that level of nuance is missing.

    Also, we don’t make the same moral arguments against other energy uses. Air conditioners use more energy than Bitcoin mining does, but we don’t go around saying the government should ban people from using AC.

    There are legitimate problems with crypto, but this one never convinced me

      Air conditioning literally saves lives, especially medically vulnerable people, the hell are you on about?

      As others have pointed out, ~2% of the entire US’s energy output is absolutely insane. According to the eia.gov, the US produced around 100 quadrillion BTUs worth of energy in 2022 (I don’t fully know why they chose BTUs to measure the total energy output, they explain on the website, but that’s besides the point). 2% of that is 2 quadrillion BTUs. According to psu.edu (I googled these sites on my laptop so don’t have exact urls on my phone at the moment), the entirety of US households in 2017 used 4.58 quadrillion BTUs.

      Think about that. Bitcoin/PoW coin miners are using enough electricity to power around half of all homes in the US. According to statista.com, in 2022 there were 144 million homes. These miners consume 72 million homes worth of energy. And for what? To solve math problems that benefits no one but Bitcoin/PoW coin investors?

      We’re literally seeing our weather patterns become more and more extreme every year due to climate change, which is also killing our oceans which is causing a severely negative chain reaction in the rest of our ecosystems… But, you know, fuck all that, I need to use an extremely inefficient method of generating currency that no one but enthusiasts/speculators/investors asked for. I’m not inherently against cryptocurrency; however, fuck Bitcoin and other extremely wasteful PoW coins.

      And yes, printing dollar bills/other fiat currencies creates pollution, too. I agree that process should be modernized as well. And in some ways, it already has been undergoing modernization as more and more people use electronic payments vs cash, thus decreasing the need to print more bills.

      It’s a lot of energy for a global (!) maximum of around 7 transactions per second.
      Unless you want to use the replica of traditional finance called Lightning Network. Then you have more transactions per second and a whole new set of drawbacks.

        Holy shit. 7 transactions a second is horrible and pretty much definitively proves (to me) that it’s not currently used as a currency

        By chance, do you have a source for that or know where I would go looking?

          Because the max blocksize of BTC is heavily crippled, max transactions per block is around 3,500ish. That puts us at about 500k transactions max per day (1 block every 10 min). So divide 500k by how many seconds are in a day (86,400) and you get slightly under 6 TPS. Whoever came up with 7 TPS probably did more accurate math than me.

            Different transactions use different amounts of space so it’s always going to be a rough estimate.
