A nice place to discuss rumors, happenings, innovations, and challenges in the technology sphere. We also welcome discussions on the intersections of technology and society. If it’s technological news or discussion of technology, it probably belongs here.
Remember the overriding ethos on Beehaw: Be(e) Nice. Each user you encounter here is a person, and should be treated with kindness (even if they’re wrong, or use a Linux distro you don’t like). Personal attacks will not be tolerated.

i strongly urge skepticism when reading articles about the environmental impacts of bitcoin. I am not saying that bitcoin is a sensible use of resources - rather that the claims made about the environmental impacts are often overstated and based on models extrapolated to absurdity. For example, see https://doi.org/10.1038/s41558-018-0321-8 where Mora, Camilo et al suggested that "Bitcoin Emissions Alone Could Push Global Warming Above 2°C". Then read Implausible projections overestimate near-term Bitcoin CO2 emissions by Masanet et al.
Again - the environmental impacts of cloud computing in general and bitcoin in particular are something we should be concerned about. But there are a number of researchers who have made wild claims that should be treated with a critical eye.

Yeah, if they had said 10 gallons, I'd buy that, but a whole swimming pool of water would be worth far more than a transaction fee I'd expect.
Yeah, generally miners will set up in places with cheap electricity. And excluding places like Azerbaijan, those sources are generally renewables.
