I’ve always found this argument against crypto to be a bad one. The headline is 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
Dude. It’s 2.3% of a massive industrialized nation where most citizens have access to some luxury goods. A nation with nearly 350 million people being the 3rd most populous country.
It does NOT fucking matter if it’s “”“”““waste””“”“” energy. And no, we don’t fucking make that arguement about things like ac because you know why? Someone is getting comfort out of it instead of burning seals to make a line go up.

Sounds like you don’t actually care about the energy use, you just hate this for moral reasons. Using excess energy has zero externalities
Yeah, its not like we could store that energy in say a battery and then use it another time when demand is higher for actually useful things instead of jerking off techbros/cryptobros.
I would love if this were an option, but it’s not. The current battery technologies don’t have the scale for grid level storage capacity. The only grid scale storage solution that is really being done is to build very expensive infrastructure that moves water between two dams of different heights, and building more of those doesn’t seem politically likely at the moment
The reality is that there is much a whole bunch of excess energy supply that is produced because power plants can’t cycle up and down with demand. So they have to keep producing at peak demand 24/7 (there is some nuances based on the type of power plant, NatGas is faster to turn on/off, but this is broadly true)
I have my qualms with Bitcoin. As a currency it has significant transaction speed problems, and potential security ones after a couple more halvenings. But I don’t see a problem if Bitcoin miners want to pay energy producers to use energy that would be produced anyway and earn the producers nothing.
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.
So what happens if a lot of people want to make transactions at the same time? Do they have to queue? Also, this sounds like anyone can cripple the system by scheduling a few thousand tiny transactions.
You can look how much space a transaction requires, how much size is available per block and how many blocks per time are being created (at average).
The only way to exceed the figure is by creating transactions with 1 (or few) input(s) and a lot of outputs as they are more efficient in terms of space per tx. Individuals rarely have use for that, but exchanges tend to do that.
If you want to do your own research, start with the fundamentals and investigate the numbers (size per tx depending on type of tx, size per block, blocks per time).
Oh yeah there are many criticisms of Bitcoin one can make, I just don’t think the energy one is very convincing if you think about it a bit
Shall I add the mountain of electronic waste to the list?
I mean, Bitcoin mining devices can literally do nothing else but calculate SHA256.
Once they can no longer be operated economically, they’re garbage.
At least Ethereum’s PoW ran on GPUs, which can be used for, let’s say: gaming!
And Ethereum showed that a transition from PoW to PoS is possible.
I think that Bitcoin sparked a great idea, but way better implementations of that idea are available. Bitcoin has a massive network effect and first mover advantage. technology wise it’s no longer on top of the list.
I agree with everything you’ve said
Pretty much the only things Bitcoin has on Ethereum today is a better brand and Lindy effect

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.
