This article seems to intentionally ignore the core reason for cryptocurrencies; escaping inflation and control. The article then proposes to use the law to bring those people back within the control of fiat and government oversight. I no longer think the environmental argument is really plausible here. Clearly crypto mining is emitting using a lot of power and some of that is CO2. But the competition is fiat; backed…
> Clearly crypto mining is emitting using a lot of power and some of that is CO2. All of it is CO2. Let me explain. When you burn energy for bitcoin mining, you don't just use capacity of your local energy producer, you are delaying removal of legacy power producers. Before a particular power producer (for example burning coal) can be turned off, the capacity must be created from other sources (for example renewable)…
Increased demand for energy brings more energy supply into the market. New energy is mostly renewable energy.
Old plants are shut down when they are unprofitable. That can be because they're inherently too expensive to run, because the carbon inputs are being taxed too heavily (I think this is a good one), or because the governing body controlling the physical location of the power plant has declared them illegal (since you can't profitably sell something you're forbidden from selling).
I'm not making the "Bitcoin is good because it drives renewable energy investment" argument, which is too handwavey for my taste. I'm saying your argument is incoherent.
Reducing carbon emissions from power plants is mainly about pricing the externality they generate. Cryptocurrencies, in fact, any application for that generated power, neither harm nor help achieve that outcome. It's irrelevant special pleading, and it's a distraction from this urgent goal.
