As Bitcoin continues to grow in market capitalization, and energy expenditure, it has been the cause of criticism. A common argument is that the mining network uses more energy than some small countries.
The problem with that statement is that it fails to dive deeper into the critical analysis required to fully understand Bitcoin’s energy consumption.
Nuances need to be explored such as: What is the source of that energy? Is it environmentally harmful to mine Bitcoin (like gold mining)? Is that energy consumption a sum zero to the energy already being wasted? What utility does Bitcoin provide to society?
Let’s first examine the utility Bitcoin provides to society:
It is a financial instrument that can be sent internationally between different parties, can be memorized and brought anywhere in the world, and can be stored offline with no counter party.
Just 13 years into existence it is the most portable, verifiable, censorship resistant and divisible asset in the world. But perhaps most importantly, it is the most scarce.
We’ve all seen the headlines recently in attempts to cancel and silence anyone that goes against the media narrative. De-platforming, doxxing and many other strategies have become the norm.
Do we expect it to stop there? What happens if the government moves forward with Central Bank Digital Currencies? They’ll be able to turn off your account, or freeze your money.
Bitcoin is in the full custody of the owner, assuming they keep it in the appropriate storage and maintain their own private keys. Nobody can ever take it from you.
We’re living in an age of soaring inflation. More than 40% of the total fiat money supply has been created out of thin air in the last couple years. This was decided by a handful of politicians without input from the people who will feel the greatest effect of these policies.
While that has benefited those holding assets like real estate and stocks, it has absolutely crushed those without. Meanwhile wages are stagnant and cost of goods have also soared. If fiat currencies continue as our primary store of value and monetary system we are heading toward the same inevitability that has plagued the citizens of Venezuela, El Salvador and Zimbabwe (to name a few).
Bitcoin has a fixed supply of 21M. There will never be any more. It is essentially wealth creation and preservation that is 100% in the custody of the owner.
Seizing of assets is a time honored tradition throughout human history.
Whether it be through property taxation, real estate seizures or the 1933 forced forfeiture of all personally held gold under penalty of imprisonment.
God forbid your country is invaded, overthrown or any other number of possibilities…do you really think your real estate holdings or 401k would be safe?
Since it is impossible for anyone to seize your Bitcoin without access to your private keys (which can be memorized) it is the only asset class that gives you 100% protection from being confiscated.
Now let’s dive into the energy conversation…
Where does Bitcoin’s energy consumption come from?
It is conservatively estimated that as much as 74.1% of all Bitcoin mining is produced from renewable energy.
Critics have said that using renewable energy to power Bitcoin mining means it won’t be available to power a home, a factory or an electric car.
However, the renewable energy that Bitcoin miners utilize is typically linked to the excess energy output from these sources. For example, in West Texas, miners buy excess wind and solar energy from providers when energy is abundant. In so doing, the miners monetize a renewable asset that would otherwise be wasted, while maintaining generally high uptime.
The same is true in the recent surge in flair gas energy usage. Miners are continuing to adapt in search of more inexpensive output.
To take it further, nuclear plants are being decommissioned around the world due to their difficulty of remaining profitable in comparison to substations and traditional power grids. What if energy companies harness this untapped resource of wasted energy to power a massive adoption of bitcoin mining infrastructure?
All of this lends credence to the hypothesis that Bitcoin is galvanizing the use of renewable energy.
Now imagine governments wish to tame inflation in the future, without plunging the world into a massive recession. They can’t raise rates to do so, like they did in the 1980’s, because most of the world would default on their massive low interest loans. They will need to choose a new system to back their money. Destroy the economy or destroy fiat currency. That is the question they are currently faced with today.
Bitcoin, with it’s huge renewable energy foundation, will be too good to pass up.
Is Bitcoin harmful to the environment?
When asking this question, it is important to not put it in a vacuum. While there is still room for improvement on the 26% non-renewable Bitcoin mining sources, the expectation is that this will continue. Conversely, we must compare Bitcoin’s environment impact to it’s alternatives:
Based on a 2014 study, gold production expends roughly 132 terrawatt-hours of energy per year. Compare that to Bitcoin’s 105 terrawatt-hours, as of 2021. These are fairly similar in energy output, however the large difference to be seen is just below the surface (no pun intended).
Gold mining activities lead to the generation of large quantities of heavy metal-laden wastes which cause widespread contamination of the surrounding ecosystem.
Modern industrial gold mining destroys landscapes and creates huge amounts of toxic waste. Due to the use of dirty practices such as open pit mining and cyanide heap leaching, mining companies generate about 20 tons of toxic waste for every 0.333-ounce gold ring. The waste, usually a gray liquid sludge, is laden with deadly cyanide and toxic heavy metals.
Gold doesn’t even come close to competing with Bitcoin in it’s preservation of the environment, or the energy required to create it.
As the world is hungry for more wealth, gold miners are beginning to look to the sea bed and oceans to begin large scale mining. How do we expect this will turn out, based on the damage already being done with land mining? Answer: not good.
Fiat Monetary Systems
As Vijay Boyapati pointed out in his article, The Bullish Case of Bitcoin, it is not just the financial systems that must be accounted for, but everything that is needed to uphold it. That is the measure of the true environmental impact of today’s fiat monetary systems.
On the surface there are the people, buildings, banks, computers and commuting systems to consider. But what backs fiat systems since it came off the gold standard?
Bitcoin has Proof of Work. Fiat currency has politics and military.
Make no mistake, without the military and the political strength of the nation, there is no way the world accepts the dollar as the world currency.
What is the environmental impact of war, planes, carriers, tanks, the gasoline to power them, the steel created to build them, the millions of service men and women? It’s almost immeasurable.
Bitcoin is housed in data centers spread around the world, typically going where the most available excess renewable energy can be used. All you need is an internet connection, and no military in the world can confiscate it because it is decentralized.
We as responsible investors must look beyond the surface of energy expenditure. Look at how Bitcoin’s energy is created, and the impact trail it leaves behind.
We must compare Bitcoin’s environmental and socio-economic impacts to the financial systems it aims to replace.
We must look at who the current system aims to enrich, and how Bitcoin aims to fix that.
It goes far beyond the surface. And once you understand those impacts, you realize there is only one true solution: buy, hold, dollar-cost-average as much as you can, and leave the world a better place for future generations of your family.
