Proof of stake still use more electricity per KB transferred than the status quo.

Not sure how this is relevant to internet? Can cows run websites?
Pretty much everything that has a large carbon footprint is going to have to be fixed to reduce that footprint, including web3.
It is when you get it (a) for free by stealing it or (b) from countries that have lax regulations.
And in both cases this is the dirtiest fossil fuels not renewables.
I would love for this to be true (and that's why I used to believe it). But there are two problems with this:
• Renewables aren't the cheapest form of electricity; low-value (dirty-burning) or subsidised fossil fuels are cheaper in many places. You've heard of people buying and re-commissioning old coal power stations for crypto mining, I'm sure?
• Using any grid electricity drives up the price of other electricity, by market forces. The effect is local, but when cryptomining is happening globally, that's a global effect. That means that otherwise-infeasible inefficient (and polluting) electricity generation is now viable.
Greenest ≠ cheapest. If this were a universal truth, we wouldn't have a climate problem in the first place.
If renewables are the cheapest forms of energy, why did the hash rate drop when Kazakhstan went off line?
Based on https://www.iea.org/reports/kazakhstan-energy-profile
> Coal represents around half of Kazakhstan’s energy mix (50% in 2018), followed by oil and natural gas (both with 25% shares).
This means that the cheapest energy to be found for is 100% carbon based and non-renewable.
Likewise, another 5-10% ( https://www.yahoo.com/now/iran-temporarily-stops-authorized-... ) is from Iran - which again is using oil, and natural gas rather than renewable sources.
From https://www.globalpetrolprices.com/electricity_prices/ - the countries with the cheapest energy prices (and show up in the hash rates) are those that are using fossil fuels (and likely trying to subsidize those prices from the government to avoid civil unrest).
really?
