Bitcoin Could Consume As Much Electricity As Denmark By 2020 (boingboing.net)
JustAnotherOldGuy writes: The numbers are very back-of-the-envelope and assume a worst case: widespread adoption of Bitcoin and not much improvement in Bitcoin mining activity, along with long replacement cycles for older, less efficient mining rigs. But even the best case [scenario] has Bitcoin consuming a shocking amount of electricity. [As mentioned in a report from Motherboard,] "The results show that in an optimistic scenario, the increase in electricity consumption of the Bitcoin network compared to now is not shocking, from around 350 MW to around 417 MW, but still on the order of one small power station. If things play out a little less favorably, however, the Bitcoin network may draw over 14 Gigawatts of electricity by 2020, equivalent to the total power generation capacity of a small country, like Denmark for example.
Cost 0.
Bitcoin. Heaven will direct it.
The Bitcoin mining reward halves every four years, making it less profitable in the future. Nearly 75% of Bitcoins that will ever exist have already been mined. Saying that miners will collectively be spending 30x more on electricity to mine 1/4 the Bitcoins they earn now is ludicrous.
Why would there ever be any improvement in mining activity energy use? Isn't it designed to scale with mining efficiency?
...or another altcoin that secures the blockchain in a more energy efficient way and/or devotes computing resources to socially responsible causes like citizen science (e.g., via the Berkeley Open Infrastructure for Network Computing). Info on Gridcoin at: http://www.gridcoin.us/. Without question, the electricity needed to secure the Bitcoin blockchain scales dramatically out of proportion to the need.
compared to the energy draw for computation for everything else, it's not worth worrying about bitcoin cycles. Even the draw for the systems that track traditional currency will completely dwarf it.
You could be using those cycles to crunch the cure for cancer.
From now on, we measure power consumption by the Denmark!
How does this compare to how much electricity CitiBank or Bank of America uses?
More like they love freedom. God bless America.
For something that is entirely useless.
This is the most pointless waste of electricity I've heard of yet. Electricity isn't free, and the fuel expenditures devoted to utterly pointless virtual currency is astonishing. Humanity has sunk to a new low of wasteful activity.
Bitcoin needs to go away. It was never IMHO a good idea and this revelation makes it even more stupid and pointless.
It was probably planned so that if it got popular enough then this issue would arise and they could say something like... well we will just terminate the blockchain here and equally distribute the rest to the governments/banks of the world to start it as a currency.
You used electricity to post this drivel.

It might not. It might consume twice as much, or possibly half. What's the point here, exactly?

The numbers are very back-of-the-envelope and assume a worst case:
Translation: We did a ridiculous and naive extrapolation and then were foolish enough to think it actually means something.
Every other currency also uses tons of electricity. The Bank of London does not hand carry over paper pounds to exchange for paper dollars, this is all done electronically. Banks are constantly manipulating and forecasting, and I don't hear people complaining about the electricity use for speculation.

electricity costs money. so as the electricity demands go up, it exacts a higher toll on the miner, the rewards become less and less as mining continues such that the effort to mine does not offset the cost in electricity. miner hangs it up.
this in turn adds to the workload of other miners still in the system requiring more electricity of them requiring more money to keep the operation running... but as always, the rewards become less and less as mining continues. effort to mine does not offset cost in electricity. miner hangs it up.
and so on and so on... won't this eventually lead to a condition in which it is no longer profitable for ANYONE to mine bitcoins? even after the line has been pushed back to only those miners who have optimized their equipment to peak efficiency using only renewable energy from the sun, it seems like you'd hit a set number of miners that the system can sustain and at that point, the number of miners stabilizes and bitcoins progressively take longer and longer to mine... or... bitcoin collapses.
no?
i know dice bought you, but seriously. click bait that is this bad? do you want to go the way of Digg?
that BC is perfectly suited to outsource mining into orbit: Energy is cheap there and bitcoins are easily beamed back... A perfect product to manufacture in space. Lol.
What a stupid idea. Fake money. Hope you all lose your asses
I thought Denmarks power all came from renewable sources anyway.
Wind, solar, hydro...
and of course tidal. If you stuck a dam across to Norway or Sweden you could use the Baltic sea as a huge source of tidal powwer.
Denmark has a power usage around 3 GW at night and around 5 - 5.5 GW during work hours.
I'm not sure where the 14 GW comes from, but it seems way off. Granted it says power production capacity, but it still seems quite wrong. The powerplants are not that powerful and the grid would not be anywhere near handing that huge amount of power. Granted there is a growing number of windfarms, but still even during a storm they deliver "only" like 3-3.5 GW. It happens occasionally that Denmark produce more power from windfarms alone than the power usage at the same time, but it's still far from 14 GW.
I'm not linking to the source for the current power production (I suspect the live updating server wouldn't cope with traffic from a link here), but the power usage is currently 3125 MW, quite far from 14 GW.
Speaking of Denmark and running on wind energy. It's not possible to shut down the powerplants even if the windfarms can deliver enough energy. The reason is that a strong generator at a powerplant has to deliver 50 Hz and then secondary power supplies like small powerplants and windfarms adapt to that. A windfarm without a clear external 50 Hz voltage will not be able to produce power as it can't figure out what 50 Hz is on its own. This is one reason why Denmark once in a while produce wind energy and export it for more or less free without shutting down powerplants. Another reason is capacity issues in the high voltage grid. The windfarms tend to be on the west coast and far from the cities needing the power and they are actually better connected to Norway and Germany than to the eastern part of Denmark. Windfarms is more than just "getting enough" once they take up a certain amount of the power production. The problems can be fixed, but not for free.
...maybe all this Bitcoin mining will ultimately lead to civilization developing and deploying a Dyson sphere.
But never been to bitcoin (or Alaska for that matter)
What's the NSA going to do with all those bitcoins?
Denmark should drastically reduce electricity consumption
This isn't really an option, the block size will have to be increased simply to stay liquid. What happens if the block size doesn't change soon? If the transaction backlog gets too big, people will lose confidence in the currency. As miners lose confidence and stop mining, a larger percentage of mining power will be controlled by big cartels. The cartels want to keep the block size small until this happens, meanwhile they will maintain the backlog and only service the high value transactions. Only when some set of cartels has a majority control of mining will they increase the block size, but at that point they will also be able to change other parameters, like the reward for solving a block, or how the difficulty is calculated. It will be a much less liquid market, but that is okay if you are actually in control of the market.
It's much more efficient to directly tax-subsidize the wealthy. Sending it through framers, ethanol producers, and energy companies, THEN to the wealthy is much more wasteful.
There won't be any bitcoins in 2020. They will have been banned. If you have any, get rid of them before owning can become a felony.

Wasting this much energy and resources on literally nothing.
Almost as "wasteful" as having similar percentages of GDP spent on building pyramids, or sacrificing food to the gods, to maintain the social order. Maybe maintaining trust between large numbers of people just does require expenditure in order to work?
Lots of CPU coolers spin up attempting to mine a little butt coinage, but it's probably a drop in the bucket compared to javascript, especially as implemented by Mozilla. You have dozens of tabs open for hours or days, but these scripts run nonstop, whether you're looking at them or not. And they do spin up the CPU fan unless you limit the CPU frequency settings (which most probably don't since many people just barely know how to use a computer).
Mozilla seems to use some sort of cooperative multitasking. It would seem sensible that after tabs that have been open (especially tabs not in foreground) should get less CPU time after say 10 seconds, and then get further continually diminishing CPU as time progresses from minutes to hours.
Chrome seems a lot better about this; although it also uses all available CPU cores. Chrome multithreads to all cores as opposed to firefox, which is single threaded, except for plugins and xorg calls. Still the net CPU time for Chrome seems dramatically lower.

Think of the developer hours and trillions of watts wasted by developers trying to get their sites working right with IE.
They're too damn busy mining for virtual coins, and putting their resources to it.
