We are thinking about Bitcoin’s energy usage in all the wrong ways



via tnw

Global warming is certainly one of the humanity’s greatest challenges. For decades, public opinion has held heavily industrialized nations accountable for the damage done to our planet. In the quest to preserve Earth, it has become en vogue to critique Bitcoin mining for its high energy use and potentially harmful impact on the environment.

Towards the end of last year, the Bitcoin $BTC▲0.83% network was running on enough electricity to power more than 20 European nations. More recently, an article was run with the headline Bitcoin mining now accounts for almost one percent of the world’s energy consumption . Under a certain light, this is certainly true.

Bitcoin mining relies on Proof-of-Work to maintain its ledger. This mining network is made up of (and powered by) computers, which obviously use electricity. As adoption increases, more computers join the network, making the whole thing quite energy-intensive. Profit and efficiency is directly tied to energy input – a seemingly dangerous business model if electricity sources are not considered.

But while the data indicates that Bitcoin uses one percent of the world’s electricity, it misleadingly suggests that (if it wasn’t for Bitcoin) that electricity would not be produced – or necessary. In fact, often is the case that the electricity used to power Bitcoin mining farms comes from a surplus of energy that countries are desperate to unload.

In the case of green-energy solutions such as wind farms and solar, it is often very difficult to store or even sell that energy if the supply outweighs demand. This problem is particularly common in countries like China – where up to 70 percent of the world’s Bitcoin is being mined.

Reuters reported that “wasted [Chinese] wind power amounted to around 12 percent of total generation in 2017,” and distributing that surplus is proving incredibly difficult because other countries in the region are also energy-rich.

Simply put, countries that attract cryptocurrency miners with cheap electricity can do so because the supply greatly outstrips the demand. Cryptocurrency mining plays an important role in normalizing international energy markets by consuming power that would otherwise go to waste.

Andreas Antonopoulos, a prolific cryptocurrency researcher and influencer, has explained the situation quite succinctly:

The energy consumption in mining, I think, is misrepresented. […] What happens when you build a 50 megawatt plant in a place where they only have 15 megawatts of demand? In some cases, if it’s alternative energy, like wind, solar, or hydro, you can’t turn it off or turn it down. You’ve built it, and it will produce, and then what? You’re basically wasting energy.

Now what if, in that environment, you can find a way to turn that energy into an alternative store of value […] by using electricity that would be otherwise wasted. Now, Bitcoin is an environmental subsidy to alternative energy all around the world.

What needs to be realised is that the advent of Bitcoin is effectively driving the decentralization of energy production, which Antonopolous notes is “one of the most important trends in human history.”

Having energy “stored” in the form of cryptocurrency offsets the costs involved of developing those solutions – especially now that we know that lots of renewable energy goes to waste. The Bitcoin mining industry actually contributes to the development of alternative energy solutions through the conversion of surplus energy into a valuable commodity, simply by making use of the electricity produced.

Canada’s largest utility, Hydro-Quebec, is a perfect example. Reuters reportsthat “the province estimates it will have an energy surplus equivalent to 100 terawatt hours over the next 10 years. One terawatt hour powers 60,000 homes in Quebec during a year.”

Not surprisingly, Bitcoin mining operations have inundated Hydro-Quebec with applications to make use of the surplus. As such, profits have been steady, a whopping annual average of roughly $3 billion over the past four years.

[Edit: Hydro-Quebec has since clarified details of its profits, and this post has been updated to reflect its data. Particularly, it pointed out that the numbers relate specifically to its profit, not revenue, as was originally reported. Surely, an important distinction.]

So much money has been generated by lucrative deals that it was “forced” to share $45 million with its customers as profits exceeded the regulator-approved rate of return. This will surely act as inspiration for other nations to create similiar renewable energy solutions.

Attacking Bitcoin mining for its electricity usage is certainly easy – it’s an obvious target. In May, Ars Technica reported that by the end of this year, Bitcoin could consume up to 7.7 gigawatts.

Antonopolous drew the following comparisons between Bitcoin’s energy usage and financial services giant VISA:

For every time you pull out [a VISA card] and use it to [make] a transaction, you’re not aware of the 100,000 square-foot data center that is churning 100,000 servers to do fraud detection, or clearing […] You’re not aware of the tower offices that are lit 24-hours a day, trading floors, the bank vaults, armored cars, and the diesel trucks […] All of those costs are mostly hidden and they’re enormous.

If the [Bitcoin] system was ten times bigger, with ten times more users, it doesn’t need ten times more mining – what we have is enough. There’s a profit motive that drives it, but it’s a mistake to think that if simply [Bitcoin] goes global, [the energy cost] will also multiply, quite the opposite in fact. Over time, the reward for [Bitcoin] mining decreases, and as a result, it is more likely we will see [the energy cost] gradually taper off and plateau.

Antonopoulos does concede there are challenges associated with managing Bitcoin’s electricity usage, but it is a complex discussion that requires consideration from many angles. The idea that by simply using electricity, Bitcoin must be bad, is nothing short of narrow-minded.

“This is a long game, […] the implications and complexity of how cost is allocated and how energy is consumed is huge,” Antonopolous declared. “I don’t think we can afford two Proof-of-Work systems on this planet, but I think we only need one.”

To which extent, the power to drive energy innovation, in the end, could be Bitcoin‘s “killer app.”


Geothermal (like Germany uses) would be an easy answer, no pollution and releases oxygen.

Having easy and thoughtful methods seems to be against the use of fuels (or logic)

Blaming Bitcoin (or Aluminium factories which use significantly more power than Bitcoin times a thousand fold) is the wrong approach. Blaming the poor choices in power production is the correct path.

Does not matter that much, changes are coming anyway and the topic will change to some other way to pick on the wrong thing and blindside the real issues.

Hello Mike, nope… geothermal is under the smallest fractions of the renewable energy production (~0.1 %) in Germany as of 2017 (Source “Umweltbundesamt” / German Environment Agency).

In contrast to oil, gas, coal and nuclear power the percentage of all renewable energy production is around 36.2 % as of 2017. Still this is a litte above the targets that the goverment had set.

See this chart here:

And here the actual percentages of all renewable energy production in Germany as of 2017:

You probably meant Iceland in terms of high geothermal power usage, right?

" Five major geothermal power plants exist in Iceland, which produce approximately 26.2% (2010)[2] of the nation’s electricity. In addition, geothermal heating meets the heating and hot water requirements of approximately 87% of all buildings in Iceland. Apart from geothermal energy, 73.8% of the nation’s electricity is generated by hydro power,[3] and 0.1% from fossil fuels.[4]"

BTW… this (relatively low power cost) is why Genisis Mining has large data centers in Iceland.

However… I can go along with some of your other assumptions. On the other hand the financial weight of Germany’s push for renewable energy’s is payed by the consumers even more so as a lot of industry’s are massively subsidized (prices for households per kwh are around 0.30 EURO cent = 0.35 US cent / as of right now).

Nice, I thought it was Germany that was pioneering the path on Geothermal, but it appears Iceland is.
I also know New Zealand has a couple of Geothermal power stations.

Seems such a simple idea to produce almost endless power without really needing fuel other than water.

The steam turbines are still pretty expensive, so can understand there is still a cost to producing power, but a cleaner way than burning fossil fuels has got to be a basic step in the right direction.

Fusion power may take over eventually, but still the cost is quite high, but at least again, much cleaner.

There are other methods of obtaining power, buy they still remain classified (for almost 100 years now, so much for freedom of information).
