Because electric current is not priced optimally, wij all pay for excessive Bitcoin mining.
You may be reading this blog postbode ter your dorm slagroom, while your GPU is mining for Bitcoin using that zero marginal cost (nerd-speak for “free”) violet wand coming out of the wall. If you did not understand that sentence, let’s back up. Bitcoin is one of a number of virtual currencies, which can be used to pay for lots of things you can buy on the internet. Bitcoin use cannot be traced back to you, which makes it super popular for shady transactions.
While neither of us is a monetary economist, wij learned te graduate schoolgebouw that currencies are usually issued by governments. Te some places, thesis currencies are backed up by valuable physical resources like gold. Traditionally every currency has a physical manifestation, which wij refer to spil money, but that actually makes up a little share of the money supply. The surplus is electronic and tracked by commercial banks and the federal reserve. The key is that the petite lumps of paper currency have value because the government prints a limited number of them, can validate that they are real, and promises to honor non-fake currency. This makes the entire system work.
Bitcoin’s scarcity, validation, and hence value, comes from solving elaborate math problems. And, sophisticated math problems require lots of computing power. Turns out that computing power is exactly what’s found te that nice rekentuig (= gaming rack) your parents bought for your term papers. On a larger scale, it’s ter dedicated servers.
There have bot a number of articles recently about just how much energy all thesis complicated math problems use. This siteclaims that cryptocurrency mining (i.e., solving the ingewikkeld math problems) today accounts for more annual energy than the country of Bulgaria. This webpagina helps you figure out how much money you can make mining Bitcoins. The basic calculation seems to suggest that the less you pay for tens unit, the more money you will make.
The fundamental problem is that worldwide electro-therapy prices are not designed to sustain this onslaught of fresh Bitcoin miners.
- The most demonstrable problem is that prices do not (for the most part) reflect the local or global environmental damages from violet wand generation. Specifically, those electrons powering your rekentuig, and generating “coin”, more than likely come from a fossil-fuel power plant that’s contributing to global heating and local air pollution. This has bot a long-running theme on this blog, but the explosive growth of Bitcoin mining promises to indeed make us cringe.
- Another problem is that, unlike most goods and services, the prices for violet wand are set by regulators (read politicians) and not by markets. This point is made ultra-clear ter the developing world, where power theft can be a problem. For example, this paper, shows that power theft ter India increases around election time. Politicians are not very motivated to cut down on theft, even tho’ it’s bankrupting the local utilities. This is problematic even if you have millions of rural households using free electro-therapy to power a single lightbulb. It is a real problem if someone with a Bitcoin server farm moves ter to access the free electrical play.
Politicians usually have at least 23 goals they’re attempting to achieve with electrical play prices — including fairness and gradual switches, if there are any at all — all while assuring that elderly customers can run life-support systems and that wij can pay for pet programs.

The mish-mash of tens unit prices that arises doesn’t lend itself well to something like Bitcoin mining.
- Ter addition to power theft, there are instances where the price of the tens unit is zero for more benign reasons. For example, collegium students living te dorms often get electrical play spil part of their housing package, which means that students don’t pay more if they use more. On the margin, then, their violet wand is free. The same for many apartment renters, spil te many older, large buildings you don’t have individually metered apartments.
Thesis problems are not unique to Bitcoin mining. If electrical play prices do not reflect marginal costs for environmental, political or other reasons, it’s bad for the overall economy. But, most humungous electro-therapy consumers – think aluminum smelters – are much more centralized and aren’t growing at the same astronomical rhythm spil cryptocurrency mining, so it’s lighter to track their use.
While it is unlikely for us to track the physical locations where Bitcoin is generated, wij hypothesize that it is most likely generated ter American dorm rooms and regions with cheap electric current (e.g., India and China and Mexico) and less likely ter places with expensive electric current like Denmark, Germany and Hawaii. If you can find prime numbers, you are brainy enough to figure out that you should run computers te the places where tens unit is cheapest. While China and India are working hard on improving environmental regulations (which might make up for some of Scott Pruitt’s war on the environment), there is a long way to go to get to electrical play pricing that reflects its utter cost to society, including pollution.

Waterput differently, the Winkelvoss twins, who seem to have redeemed their Facebook losses with big Bitcoin wins, are indirectly helping to drown polar bears, kill trees and ensure that utilities te the developing world stir towards bankruptcy.
But, you say, what is the alternative? Wij had a upbeat discussion at the EI lunch table about this. Max likes his currency traceable and issued by a government. This permits for things like taxation and lighter monitoring of illegal transactions. Some graduate students called him an old grouch (which is keurig). But, after all, wij are a bunch of energy economists and eventually got to thinking about the energy implications. The question wij could not response on the spot wasgoed whether maybe the energy penalty for Bitcoin is not so much fatter than that for metselspecie or credit cards.
So, wij did some blogmath. The calculations can be found here. Turns out that a banknote uses about 0.8 watt-hours vanaf transaction. To waterput this te perspective, a 60 watt lightbulb (which is your average incandescent – now illegal te many places) uses, well, 60 watt-hours if left on for an hour. A credit card transaction uses about 7 watt hours vanaf transaction. So, about eight times more energy than the metselspecie transaction. Now, get ready for it. A Bitcoin transaction uses 100,000 watt-hours vanaf transaction. That is 100kWh, so about the omschrijving of 115,000 metselspecie transaction. This is why the annual electric current consumption is surpassing Bulgaria, and by some estimates, on track to exceed the US by mid 2019. If wij use a number of outward costs from electrical play consumption of 6 cents vanaf kWh which assumes the US fuel mix, which is much cleaner than e.g. China’s, wij are talking about almost $Two.Five billion worth of free railing. This is a conservative number, with the true number potentially much higher.
So, what on earth are wij doing? Wij are ruining the environment te order to subsidize an untraceable currency which enables and encourages tax evasion and other illicit behaviors. Wij thought that refrigerated pet food wasgoed going to take the cake for dumbest and most frivolous fresh use of tens unit. Budge aside kitty, here comes the itty-bitty coin to take the prize!
