One popular critique of bitcoin is energy cost per transaction. This doesn’t begin to capture bitcoin’s massive energy savings compared to fiat currency.
Article by Peter St. Onge from Mises.
Bitcoin’s cost per transaction is well known, and often critiqued; one article in Wired magazine called bitcoin “[a] big middle finger to earth’s climate.” This is because bitcoin’s security, redundancy, and architecture are more energy intensive than traditional payments relying on a single point of failure.
Comparing the energy of a single transaction barely scrapes the surface of the dollar’s carbon footprint, which includes the entire financial infrastructure supporting fiat—8.4 percent of GDP in the US alone, slightly behind manufacturing. This includes 80,000 bank branches, 470,000 ATMs in the US alone, and forests of skyscrapers towering over most cities on earth.
Alas, that’s still only the beginning. Because paper money allows governments to print unlimited amounts of debt, that causes various collateral damage including inflation, recessions, and trillions in wasteful spending or endless wars whose costs are hidden by debt financing. These all, of course, carry catastrophic human costs that can only be imperfectly expressed in a carbon footprint.
Still, we can take a stab at addressing that disconnect by estimating the carbon footprint of just one element of fiat collateral damage: the modern recession.
First, how does fiat money cause recession? This was well known in economics for centuries before the Keynesian dogma turned mainstream economists into court jesters.
The key element is that central banks push interest rates below the market rate, flooding easy money into the economy. This boom gradually sparks price inflation, at which point central banks slam on the brakes and jack up rates, tightening money. That whipsaw leads to a mass extinction of low-quality projects funded by easy money.
The end result is a boom-bust cycle that, like a tissue fire, burns too bright and too short, leaving behind ashes.
How does bitcoin fix this? Bitcoin takes purchasing power out of central banks’ manipulation space, dulling their ability to cause cycles. If enough dollars are sold for bitcoin, this drains that space until central bank manipulation no longer sends the entire economy into recession.
How to translate that into carbon cost? We have a very elegant instrument connecting the two: the energy cost of a dollar of GDP. Because every watt that humans use is to achieve some goal—to seek “a more satisfactory state of affairs”—it means we can estimate the carbon footprint of a dollar of lost wealth, specifically how much energy it would take to rebuild that wealth were it destroyed. Tally up the dollars lost in a recession and we can estimate the carbon footprint.
So let’s plug in the numbers and compare bitcoin to the dollar.
First, what’s the carbon footprint of bitcoin today? This is trickier than it looks, because a large share of bitcoin mining is powered by green energy. Smart Energy says 39 percent of bitcoin energy is renewable, while the Global Cryptoasset Benchmarking Study estimates that three-quarters of cryptocurrency mining uses some renewables in its energy mix. Either way, bitcoin is far greener than the rest of the economy, which averages 11 percent renewable use.
A big reason why bitcoin loves green energy is that bitcoin mining can be located almost anywhere on earth, while renewables are often located in strange places like the Himalayas, the Sahara, or the Quebec tundra.
This means that bitcoin can use otherwise useless energy, and it also means bitcoin miners actually “bootstrap” new renewables, paying the operating costs until regular customers can relocate. As even a hostile article from Vox admits, “Many renewable power generators are so poorly located and underused that mining Bitcoin has become the only viable use for that electricity.” Without bitcoin mining, that energy may have just been flushed.
Still, for now we’ll ignore bitcoin’s green preference and just take the total, because, as we’ll see, it’s not even close. As of March 22, 2021, the widely cited Digiconomist estimates a total energy use for bitcoin of 86.1 terawatt hours (TWh) per year, comparable to Switzerland’s 8.5 million people, for the perhaps 100 million people worldwide who use bitcoin. In terms of nationality, given that 19 percent of bitcoin nodes are located in the US, Americans might account for roughly 19 percent, or 16 TWh, of that usage.
So that’s the cost: 86 TWh per year, of which perhaps 16 TWh is Americans.
Now, it’s central banks’ turn: What is the energy cost of a recession? It’s fitting that our most recent recession, in 2008, is the very event that drove “Satoshi Nakamoto” to create bitcoin.
There are a variety of estimates of how much wealth the 2008 crisis destroyed, depending on what’s counted and on the time period. According to the Federal Reserve itself, from peak to trough the 2008 financial crisis destroyed $11 trillion in household wealth in the US, going from $70.9 trillion in Q3 2007 to just $59.9 trillion in Q1 2009.
Outside the US, many countries in Europe suffered even larger drops in GDP, while other countries, such as China, suffered little. To get a rough sense, Credit Suisse estimates that 31 percent of global wealth is held by Americans, so one might multiply America’s $11 trillion by about three to get worldwide losses.
Next, we can put an energy cost on those trillions. According to the US Energy Information Administration, in 2018 it took about 5,000 British thermal units (Btu) to produce a dollar of GDP. The World Bank gives similar estimates for the rest of the world, at 5,200 Btu per 2017 dollar. There are 3.4 Btu in a watt hour, so that converts to 1,500 watt hours, or 1.5 kilowatt hours (kWh), per dollar.
Now, multiply the trillions lost by 1.5 kWh and you get 16,500 TWh in the US alone. Scale by 3 and you get perhaps 50,000 TWh worldwide in lost wealth. Between 500 and 1,000 times bitcoin’s annual use, all from a single recession.
Put differently, it would take between 500 and 1,000 years of mining just for bitcoin to match the carbon cost of the 2008 recession alone. Add in the other 17 recessions the Fed has created in the past century alone—one every 5 years—and that’s an awful lot of carbon. Indeed, divide that 2008 recession footprint by a recession every 5 years and you get an annual recession carbon footprint about 100 to 200 times higher than bitcoin.
Several fun implications follow. First, that central banks are vastly more polluting than bitcoin, indeed more polluting than the worst industrial offender you could imagine. Second, this estimate implies that if bitcoin makes it harder for central banks to cause recessions, it could pay back every watt many times over. For example, if bitcoin reduced the odds or magnitude of central bank recessions by just 2 percent, bitcoin would actually save us far more energy than it uses.
Of course, considering recessions destroy millions of lives in addition to the evaporated wealth, it sounds like a fantastic bargain. Throw in the possibility that, by reducing central bank manipulation, bitcoin could help limit inflation, prevent Wall Street bailouts, and reduce unnecessary wars with carbon footprints all their own, it’s pretty unbeatable.
Now, there is a second, more sophisticated, line of attack which admits that fiat is polluting but argues for other cryptocurrencies that use less energy. These alternatives might be “proof of work” altcoins with smaller rewards, or they could be “proof of stake” coins that replace energy with capital deposits.
While these alternatives could well use less energy, at the moment we simply don’t know if either is secure enough. After all, if bitcoin is already 100 times greener than fiat, trying to eke out another 1 percent in savings while putting the entire project at risk would be picking up carbon pennies in front of a fiat steamroller.
Given we live in a world of irresponsible bankers and still immature altcoins, for now bitcoin remains the safest bet for reducing the enormous energy wasted rebuilding our economy every 5 years. So, if you really do prioritize the environment, stop obsessing about altcoin deck chairs and come help us steer around the fiat money iceberg.
‘The Purge’ by Big Tech targets conservatives, including us
Just when we thought the Covid-19 lockdowns were ending and our ability to stay afloat was improving, censorship reared its ugly head.
For the last few months, NOQ Report has appealed to our readers for assistance in staying afloat through Covid-19 lockdowns. The downturn in the economy has limited our ability to generate proper ad revenue just as our traffic was skyrocketing. We had our first sustained stretch of three months with over a million visitors in November, December, and January, but February saw a dip.
It wasn’t just the shortened month. We expected that. We also expected the continuation of dropping traffic from “woke” Big Tech companies like Google, Facebook, and Twitter, but it has actually been much worse than anticipated. Our Twitter account was banned. One of our YouTube accounts was banned and another has been suspended. Facebook “fact-checks” everything we post. Spotify canceled us. Why? Because we believe in the truth prevailing, and that means we will continue to discuss “taboo” topics.
The 2020 presidential election was stolen. You can’t say that on Big Tech platforms without risking cancelation, but we’d rather get cancelled for telling the truth rather than staying around to repeat mainstream media’s lies. They have been covering it up since before the election and they’ve convinced the vast majority of conservative news outlets that they will be harmed if they continue to discuss voter fraud. We refuse to back down. The truth is the truth.
The lies associated with Covid-19 are only slightly more prevalent than the suppression of valid scientific information that runs counter to the prescribed narrative. We should be allowed to ask questions about the vaccines, for example, as there is ample evidence for concern. One does not have to be an “anti-vaxxer” in order to want answers about vaccines that are still considered experimental and that have a track record in a short period of time of having side-effects. These questions are not allowed on Big Tech which is just another reason we are getting cancelled.
There are more topics that they refuse to allow. In turn, we refuse to stop discussing them. This is why we desperately need your help. The best way NOQ Report readers can help is to donate. Our Giving Fuel page makes it easy to donate one-time or monthly. Alternatively, you can donate through PayPal as well. We are on track to be short by about $5300 per month in order to maintain operations.
The second way to help is to become a partner. We’ve strongly considered seeking angel investors in the past but because we were paying the bills, it didn’t seem necessary. Now, we’re struggling to pay the bills. We had 5,657,724 sessions on our website from November, 2020, through February, 2021. Our intention is to elevate that to higher levels this year by focusing on a strategy that relies on free speech rather than being beholden to progressive Big Tech companies.
During that four-month stretch, Twitter and Facebook accounted for about 20% of our traffic. We are actively working on operating as if that traffic is zero, replacing it with platforms that operate more freely such as Gab, Parler, and others. While we were never as dependent on Big Tech as most conservative sites, we’d like to be completely free from them. That doesn’t mean we will block them, but we refuse to be beholden to companies that absolutely despise us simply because of our political ideology.
We’re heading in the right direction and we believe we’re ready talk to patriotic investors who want to not only “get in on the action” but more importantly who want to help America hear the truth. Interested investors should contact me directly with the contact button above.
As the world spirals towards radical progressivism, the need for truthful journalism has never been greater. But in these times, we need as many conservative media voices as possible. Please help keep NOQ Report going.
