We know they're not. Bitcoin miners seek out the cheapest energy, which is mostly fossil.
We know that even decommissioned fossil fuel power plants are being reopened for this purpose.
That's not some kind of SJW propaganda, you can read about it in the Wall Street Journal: https://www.wsj.com/articles/bitcoin-miners-are-giving-new-l...
My understanding is that the cheapest electricity sources are a result of massive excess energy available far from population sources. These are often renewables including hydro, wind, solar, nuclear and geothermal. In some cases older coal plants with excess capacity will be cheap in the short term, but these are always going to suffer from material operating cost per Gigawatt to pay for fuel, unlike renewable alternatives which mostly require upfront investment but not ongoing fuel expense.
Once the capital is spent on renewable capacity it is a sunk cost and the marginal cost of electricity production is close to zero. That can never be the case for coal or othe fossil fuels that will always have some marginal fuel cost per unit of electricity produced.
If dirty coal and other hydrocarbons are the problem, lets tax or ban those.
You should be more concerned that your government hasn't banned coal power generation.

The problem needs to be solved at the source, burning fossil fuels needs to be stopped, today!
Turning off bitcoin would immediately remove a sizable developed nation sized chunk of annual co2 production, and would negatively impact practically nobody in comparison.
People fixate on it because it would be a trivially easy win.
The tundra in Siberia holds methane equivalent to 100 years of 2020 emissions. When that stuff starts melting (and it's already exploding) the bitcoin experiment will be a drop in the ocean.

To:
> Global warming is real, but it's not our fault.
To:

To, finally, sentiments like this. Summarized as:
> Global warming is out fault and we could fix it. But why bother, it's too far gone already.
At this point pessimism has set in. I'm just tired. COVID showed us that the capacity for personal sacrifice in western nations is very low indeed. I don't expect anyone will want to do anything about global warming if it threatens their job, hobbies, or investments. Long term consequences be damned.
We just don't have societal mechanisms that would do this. Look at veganism or similar movements (like the collective movement around quarantine, masks and vaccines). People just do not want to change, they do not want to think rationally or can't and they will mock everything that challenges their status quo.
We've made great technological strides in energy efficiency over the last few decades. From more efficient lighting and appliances to electric cars to cheaper clean energy sources like photovoltaics. By contrast, Bitcoin in a new technology that is not an efficiency improvement. In fact, it threatens to wipe out all that incremental progress. It's a heel-turn from a sector of the economy that, for a time, held the promise that it could find a way for us to address global warming through technological innovation.
What about mass international air travel? There are lots of novel things happening, why focus on bitcoin?
Besides, I don't work in the fracking industry, I work in the software industry. And it's painful to see my industry contributing to the problem in such a thoughtless way. Maybe if this was Fracking News and people were bashing on bitcoin you'd have a point.
What about banning people from going for a drive just for fun, or on a holiday via aircraft ?
It's a lot easier for governments to ban coal fire power stations and fracking replacing them with renewables and hydrogen storage.
This is actually something we can control and do without taking over people's freedoms.

A store of value is a valid use case of a currency and Bitcoin has proven to be an amazing store of value compared with all fiat currencies that have been debased by their respective governments.
Bitcoin may also someday prove to be a viable unit of account in the future as it stabilizes and matures in price discovery, but fiat currencies by design will never be good stores of value.
Any Austrian school economist who understands the benefits of the Gold standard would tell you that the hard fixed supply of Bitcoin makes it a better currency for the people than any fiat currency.
My understanding is that close to 100% of gold is mined using non-renewable energy. 100% of gold is strip mined in a rape of the planet that leaves the land completely unusable.
Gold production is at least 10x as environmentally destructive as bitcoin, half of which is mined using renewable energy.
I vote we ban coal plants and strip mining and boycott any country that violates the pledge. If we are being objective we should focus our efforts on the largest sources of pollution. Energy production isn’t the problem. Dirty energy production is the problem.
Since Bitcoin miners are mobile and constantly seeking the lowest cost electricity, if we ban dirty electricity production, Bitcoin actually incentivizes the production and development of new clean energy sources by opening up remote options that were not previously viable.
Agriculture, fossil fuels, transportation and manufacturing for single use products are some of the highest order problems to me.
It's burning fossil fuel, transport and deforestation that causes climate change. For all you know, the worlds biggest miners are using renewable energy? I mean that could be theoretically possible.
