Is Bitcoin Mining a Real-World Environmental Problem?

First time accepted submitter HeadOffice writes "Mark Gimein points out that Bitcoing mining uses a lot of power, enough that it is a real world problem: 'About 982 megawatt hours a day, to be exact. That’s enough to power roughly 31,000 US homes, or about half a Large Hadron Collider. If the dreams of Bitcoin proponents are realized, and the currency is adopted for widespread commerce, the power demands of bitcoin mines would rise dramatically. If that makes you think of the vast efforts devoted to the mining of precious metals in the centuries of gold- and silver-based economies, it should. One of the strangest aspects of the Bitcoin frenzy is that the Bitcoin economy replicates some of the most archaic features of the gold standard. Real-world mining of precious metals for currency was a resource-hungry and value-destroying process. Bitcoin mining is too.' However, not everyone is convinced that virtual mining is as bad for the environment as the real thing."

      A "watt" is a unit of power, or a rate of energy use. One watt is one joule per second (it is also one volt times one amp - units can have many ways of expressing themselves - see http://en.wikipedia.org/wiki/Watt ). Thus as you say:

      41MW is a rate of [energy] flow, not a measurement of volume. This is a 2 dimensional vector.

      This is not a "2 dimensional vector", it is a pure magnitude, though I suppose you could call it a one-dimensional vector as it could be negative or positive giving at least a sense of "direction", though of course the zero-value is fairly arbitrary.

      [MW] are made up of volts, amps, without time. It is an instantaneous measurement of flow at a specific instant in time, not over a span of time.

      Well, amps are a rate of charge, so that has time built in right there. Watts can be instantaneous or averages over a span of time, just like speeds.

      41MWh is a volume of energy usage.

      I wouldn't call it a "volume" as that has a lot of geometrical intellectual baggage associated with it, but this is correct that a rate (watts) multiplied by a time (hours) gives an amount (in this case an amount of energy as you say).

      41MW per hour is the same as above. These are 3 dimensional vectors. They are made up of volts, amps, and time.

      No, 41MW per hour is not the same as 41MWh. A rate (watt) divided by a time (per hour) gives a rate of change of the rate - analogous to an acceleration. Since energy is not a vector, the rate of change of energy (power) is also not a vector, and neither is the rate of change of power. This "watts per hour" is virtually always an error, and not actually of any use to anyone.

      41MW hours per hour would be a rate of accelerating power consumption, this is like 9.8 meters per second per second for gravity.

      Not really, as you mentioned above, MWh (often written as MW hours) would be a unit of energy, so "MW hours per hour" is an energy per time measurement, or a power. In fact the "hour" parts simple cancel meaning that "41MW hours per hour" would be exactly 41MW.

      1) What Bitcoin actually -generates-, the bitcoin itself, has no value beyond what people ascribe to it. Now I know basing your currency on precious metals and the like isn't perfect either, but they're much more stable. Unless something goes seriously wrong, your 1 ounce of gold isn't going to fluctuate too greatly in price overnight, so the value of your dollar isn't going to fluctuate too wildly either, market changes not withstanding. Contrast that to Bitcoin. Yes, you can readily change it to and from real money. How much real money are you actually going to get, though? How much is that going to be in...a few hours?

Why generate a useless encrypted token when you could sell that CPU usage toward solving a problem which requires up to millions of years of runtime. There are plenty of companies out there, biochemical, the military, Google, who would probably jump at the chance of being able to "rent" out some sort of distributed system ala SETI@Home. Create some sort of a (relatively) fixed rate based on how many packets of data your computer does in that time. Not only will you be using the CPU power to solve a problem with real world applications, you're skipping the necessary intermediary of Bitcoin and you're being paid -directly- for the work you're doing.

      3) The problem of efficiency, which you brought up yourself. Most people's computers aren't efficient enough to produce value at less than the cost by the looks of it. It's a simple math problem you can do on the back of a napkin -- you generate some Bitcoins. You have to pay your power bill.

The mining reward (which eventually dwindles to zero after all 21 million bitcoins have been created) is both the process by which bitcoins are gradually created at a controlled rate, and an incentive for early adopters to bother mining before the system is widely accepted.

      Here is an attempt to provide a basic example to help explain how fractional reserve banking expands the money supply:

      Suppose that somebody starts a bitcoin banking operation. They:
      - Require you to agree that one bitcoin, and one satoshi, is as good as another.
      - Provide interest on your deposit.
      - Make loans to to others.
      - Maintain a 10% or larger reserve of BTC on-hand. The rest can be tied up in (hopefully well managed) loans.

      Now consider this sequence of events:

      1) You deposit 100 BTC in an interest bearing savings account. Basically, the same thing you do with dollars at your bank. You do this to earn interest, or for other banking services. And because it is harder to stash bitcoins under your mattress than it is to stash gold.

      2) CoboyNeal want to buy something from CmdrTaco. The bank loans him 90 of your BTC to make the purchase.

      3) CmdrTaco deposits his 90 BTC, hoping that one day the interest will be enough to buy a taco.

      4) samzenpus wants to buy something from Mark Gimein. The bank loans him 81 BTC of CmdrTaco's BTC to make the purchase.

      5) Mark Gimein deposits the 81BTC...

      As you can see, the cycle can continue for a long time, until finally the bank can not loan out another satoshi without going below 10% reserve. Realistically, the bank would stop sooner so it can stay well above that 10% reserve even when a few BTC are withdrawn.

      Now take a look at what has happened:

      * As of Mark's deposit, there are 271 BTC in the system. 100 real and 171 borrowed. Clearly the some have been borrowed twice.
      * You think you own all 100 real BTC. CmdrTaco thinks he owns 90. And Mark Gimein thinks he owns 81.

      All this works as long as there is not a run on the bank. And as long as either enough BTC comes into the system to pay interest. Or as long as the depositors use their interest to buy goods from the debtors, thus giving them money to pay off the interest. Of course, a point will come when somebody can't pay, thus introducing the problem of bankruptcy.

      Also note that a small change in the 10% reserve has a huge affect on how many perceived BTC the initial 100 expands to be.


      There are many ideas out there to control, mitigate, or eliminate this expansion of money. There is also an argument that so long as loans are possible this effect can not be fully eliminated.

If a bank lends someone a million dollars, it isn't "out" a million dollars, because that debt is accompanied by, at the very least, a promise to pay that debt, and frequently physical collateral too. Want proof? The loan instrument itself is actually sellable - by the bank. The bank can go to third parties, and sell, for more than a million dollars (assuming the debt is to a good risk, and the amount to be repaid exceeds the million dollars loaned), the entire debt. Happens with mortgages all the time, and only becomes a problem if the bank misrepresents the riskiness of the debt (which is in large part what happened in 2008.)

      Now, on the lowest level, FRB is simply a process whereby a bank can have only a fraction of the currency needed to represent its assets (because most of its assets are loans, etc.) How much currency the bank needs is simply the amount of actual cash people may need. If their reserve is too low, then they run an increased risk of having problems during a bank run, but by and large they're OK.

You would, however, have to encourage a large portion of the Bitcoin community, who by and large are the kind of people who think FRB is a terrible threat to the economy, to deposit their money in banks, and do a significant amount of transactions in the form of bank transfers (checks, credit card payments, etc) rather than by "physically" extracting their bitcoins from a bank and re-assigning their bitcoins to a third party.

      Would you say gold is a pyramid scheme, because it was easier in the beginning? Bitcoin is in many ways digital gold, where the rarity comes from the resources it takes to "extract" bitcoins. Gold itself is not currency, but can be bought and sold. And also have fluctuations in value.

      Personally I think bitcoin will be doomed in the long run, since there's a max limit to amount of coins, and coins will slowly fall out of the system (if the cryptographic wallet key is lost, all coins in that walled will be unable to be moved to a new address - and with time and Murphy's law, more and more coins will be rendered inactive).

    But what you NEED for a currency to be usable is some stability. Deflation is bad because it causes people to hoard and to much inflation hurts as well because if you pay me now, I will have far less tomorrow.
