Yeah, Sweden has an extensive ore mining sector. I expected to learn about the energy efficiency of different mining techniques, would be really interesting.
Extra specifically: Proof of Work cryptocurrency mining.
> Our conclusion is that policy measures are required to address the harms caused by the proof of work mining method. It is important that both Sweden and the EU can use our renewable energy where it provides the greatest benefit for society as a whole.
Judging by the comments here in this submission and overall on HN, not everyone is aware that different cryptocurrencies have different strategies for consensus.
For example, I've seen calls to action from a lot of HNers to ban all cryptocurrencies because they are destroying the environment, missing completely that PoS even exists and has nowhere near the impact on energy usage as PoW.
Kinda. There are currently two chains that can be called "Ethereum" right now, commonly known as Eth 1 and Eth 2, and funds have started moving to Eth 2 via staking (currently the Eth 2 contract running on Eth 1 is the largest holder of Ethers on the Eth 1 network). You can use Eth 2 already, but can't transfer funds back to Eth 1 yet and the chains haven't been "merged" yet.
