back to article US warns cryptominers must cut power use to avoid busting US carbon goals

A White House report on the energy costs of cryptocurrency mining in the US is recommending swift policy actions to avoid disrupting the country's efforts to reach carbon neutrality by 2050.  The report [PDF] from the White House Office of Science and Technology Policy (OSTP), crypto asset mining in the US uses the same amount …

    Comparing wax apples with silk poppies

    Which is to say it's fairly irrelevant to compare power usage for bitcoin to residential lighting. They have noting to do with each other, and its been quite a while since home mining bitcoin was a thing. That and most residential lighting has shifted to high efficiency technologies.

    Bitcoin is likely going to be one of the only players on the proof of work side if Ether successfully pivots. The also go out of their way to highlight off chain transactions in exchanges as a dangerous unknown, when they are simple accounting transactions and use less crypto and power than a proof of stake transaction that they themselves indicate use a fraction of the power a bitcoin transaction does.

    While power saving wherever we can is important, I'd rather they start with dirty and inefficient ones like rail traffic, shipping and trucking, industrial processes and other problems that are the other 99% of energy used. Proof of work is already here, and SOL and Avalanche and whatever comes next will tear down Ether quickly and bitcoin over time regardless of government action. Bitcoin will probably start pushing majority traffic off the blockchain to cut costs, at the risk of handing the least trustworthy pert of the ecosystem complete control of the transaction.

    It is also likely that many of the early generation blockchains will enter the final winter during the climate crisis years, and would have even if global warming wasn't a crisis, just due to the pressure of newer and more capable crypto networks enabling an ecosystem that exists for more then mere speculation. That's never going to be Bitcoin, so it's future is by no means guaranteed, and the value and difficulty will fall accordingly. Regulators may still be shooting themselves in the foot trying to regulate it at that point.

        Don't confuse the ponzi tokens based on Ethereum contracts with cryptocurrency. It's like comparing a valuable commodity to nectar points.

        The main problem with cryptocurrency is that your average Joe can't tell the difference between a true cryptocurrency and a token that exists as part of a smart contract on top of a blockchain.

      As already said, this is so utterly ridiculous that you must have quite some money in cryptomining to be able to say it without gagging.

      Cryptomining is pure waste, it's like a broken pipe spewing water out to disappear in the dirt. And here is somebody who comes along and says, without blushing, that "instead of mending that broken pipe and stop losing all that water, we should rather review the water consumption of clothes and dish washing machines" (understood, "while that broken pipe keeps watering my garden for free").

        Both approaches are wrong. There's no time to address the issue piecemeal. Every Joule used is the Earth being destroyed, all must be accounted for and authorised as appropriate by a higher minded authority. We need only apply a simple test: will each unit of energy be used in a way that's absolutely necessary to keep an individual alive, will it contribute to the greater good or will it be wasted for selfish reasons? If it's the last, it must be saved and given to someone else at a later date.

                I understand and would agree with your sentiment in less dangerous times. Unfortunately, The People can't be trusted to consistently vote in their own interests. It's very rare for truly society changing decisions to be approved by politicians who are constantly seeking reelection.

                For example, the upcoming IC vehicle bans have probably only gotten as far as they have because the majority of voters don't understand how much the majority will have their lives changed in order to save the planet; it's essentially the end of the working (and some of the middle) classes owning personal transportation. They're also in the future so there's nothing to prevent these decisions from being reversed.

                Cryptocurrency is a low hanging fruit but it alone doesn't address the issue that people feel generally entitled to use as much energy as they can buy, as they see fit. However, it can be used as a convenient justification to bring in larger changes that will save us all, helped along by those who have all their attention focused on just miners. There would still be choices but, for example, it might be between buying a powerful computer you can only use for an hour a day or a more efficient one that you're allowed to use all afternoon. Equally, you could choose to have a longer shower or you could choose to heat your home to a higher temperature.

                    I call this the "thick voter" problem. Unsophisticated people can be persuaded to support views against their own interests, by clever demagogues. In the 19th century, John Stuart Mill proposed education as the solution, but maybe went too far by suggesting that potential voters would have to pass some sort of competency exam before they were allowed to vote. Bear in mind that when Mill was writing, only male property owners could vote, which was of course a totally unfair criterion, leading to severe lack of representation of large sections of the population

          Rubbish. We are smooth brained chimps...our problem isn't energy scarcity...because it isn't scarce...everything in the universe contains energy...the problem is we haven't worked out how to efficiently store it yet because we're still dumb apes.

          Don't ever buy into "energy shortage" bullshit. It's artificial and has absolutely nothing to do with the amount of energy available, it is literally everything to do with "the amount of energy we know how to make".

          We're still in the "burn shit to make steam to turn the thing" age. We're slowly moving into "put the thing in the wind or moving water to turn the thing stage". After that we're in the "fuse the things to turn the thing" stage. At that stage, there are no energy shortages...ever.

          We may even move into the "put flat stuff in the desert and hook them up to batteries stage" if we can just finally get graphite batteries sorted...what the fuck is taking them so long?

          I mean shit, there is a firm in the US that has worked out how to make AA batteries from nuclear waste.

            So while your statement that "energy isn't scarce" is true, it is also totally meaningless. Usable, clean energy is very scarce. So scarce, that we continue to burn fossil fuels for the majority of our energy needs. So scarce, that we cut down forests for wood pellets. So scarce, that the gasoline price may decide the election outcome in our largest democracies.

            The scarcity of clean energy may come to define this century. Already, we saw energy-intense and dirty industry migrate to poorer and less-democratic places -- fundamentally reshaping the development of our world. These forces won't diminish and will define the conflicts of this century. Oil and gas in the black sea may well have tipped the scales for the Ukraine war.

      The whole point of Bitcoin is it cost you something to make it. Unlike the paper dollars.

      If you want a true comparison, you will need to add all the infrastructure, buildings, Datacenters and Telcom requires to process one card or check transaction from one bank account to another. I have no doubt bitcoin is cheaper in that respect, but it does not scale well and in its current form will never replace our current system.

      What should concern everyone is to battle inflation the US is wrecking the economy instead of making the one thing we all use - energy - cheaper which would stabilize inflation. We need to be strong to be able to move to low carbon solutions not starving and out of work.

          Actually I do. I worked and built the infrastructure for 20 years in banking. Specifically the card systems.

          Let’s start with the receiving bank with all the buildings and power for them, employees, and what it requires for them to get to work. Next is the network infrastructure owned by say ,MasterCard, and the buildings and all those employees. Then finally the bank with the account the money comes from and all it takes. And don’t forget the bloated federal wing of money stuff.

          Bitcoin cuts thru all of that, seller / buyer / network.

          Bitcoins that I mined uses ASIC not GPU, that is ETH. Is it wasteful? Heck yes. That is the point. It cost to create it, so it has value. The dollar requires a lot less and you and I have no control over how much is created.

          If someone has a better idea how to trade now is the time to speak up. I had 30% of my on hand cash value taken from me in the last calendar year, just like everyone else.

            There is no way that it's costing about 1% of global energy usage to produce and support the infrastructure for credit card (and other bank transfer) processing. Even with all those buildings and people involved, it's still a fraction of the energy used by Bitcoin and other crypto currencies.

Entire consoles consume less and can be hard locked to limit gaming to a socially and environmentally responsible number of hours per week. If there's more than one person gaming, the time can be limited to each account, linked to government ID, which would also help end hate speech in online gaming.

        A Sinclair ZX80 cannot "easily do your bookkeeping and taxes" and its power consumption (combined with the required display and cassette recorder to presumably load this unstated bookkeeping and tax software) far exceeds the power usage of many modern day computing devices, such as smartphones, tablets and laptops. Also, cruise ships emit far more carbon per passenger per kilometre than flying.

          @mecmec: re power consumption: you are technically correct, as a ZX 80 has a power supply of 9V @1.4A == 12.6 Watts, and a ... say, a Raspberry Pi 2B will run on 5V @ <= 2A which is <= 10 Watts. The display display is irrelevant to these calculations, since each computer must have a display device, and you can hook a ZX-80 to a flat-panel TV/monitor. And yes, the cassette recorder will consume some additional power.

          The point I was trying to make with my "ZX-80" comment was that the computer tasks which are most energy-demanding are also the least "necessary", i.e., watching or transcoding videos, playing modern video games, and doing things which use GUIs, and that the "Ban GPUs" AC was insisting on a global sacrifice which would not affect that AC.

            The display device is not irrelevant. A ZX80 needs to be constantly plugged in and drawing power. A modern phone or tablet has a built in display, can be charged in an hour or two, has access to modern, intuitive, accounting and spreadsheet solutions and will last for a day or two without being plugged in at all. I understand the point you were trying to make. My point was that the analogies you were making (not just in relation to the ZX80) were very poor. Even now you're moving the goalposts, I have to tell you that entertainment is an important aspect of life and no less 'necessary' now than it was in 1980. And thank god nobody has to spend hours typing in games manually from Sinclair Magazine or making x attempts to reload something from cassette because analogue tape loading was so unreliable.

Environmentally-best choices are difficult-to-impossible to make because the choices are never (accurately) "factor A vs factor B". It's "consider factors A, B, C, D, E, F ..." The factors to make the environmentally-best choice of cruise ship vs jet plane are not just carbon emitted per passenger-kilometre. They also include things such as the environmental costs of extracting, manufacturing, storing, and transporting bunker oil vs Jet-A, the likelihood of spills, the average amount spilled, the environmental damage done by each sort of spill, etc. Then, there are the environmental costs of extracting, transporting, refining, storing, forming (melting metal and plastic to form them releases chemicals into the air) the materials which make up cruise ships vs jet airplanes. Then there's average lifetime of each vessel/aircraft, the environmental costs to dispose of them, etc.

          There are many (frequently-competing) moneyed interests who wish the true environmental costs of Thing X to remain hidden.

      The maximum power draw of any GPU currently available for purchase is under 500 W.

      "They're the ones that miners are using"

      Miners are certainly not all running RTX 3090 Ti. Miners use GPUs with the best cost/performance ratio. An RTX 3070 costs four times less than a 3090 Ti, gets better than half the performance while using less than half the power. Guess which one people interested in actually making money will choose. This is why normal people have had trouble getting hold of GPUs for the last few years - miners want exactly the same GPUs as everyone else. If they only wanted the high-end cards no-one would have noticed, because no-one else actually wants to buy them. Complaining about high-end GPUs is like complaining about expensive sports cars; there's absolutely no point worrying about one person buying a Bugatti Veyron while ignoring the millions of people driving Ford Focuses.

      "no one needs to play games... Entire consoles consume less and can be hard locked to limit gaming to a socially... responsible number of hours per week."

      You're an idiot.

    Yeah right ..

    Like they give a flying monkey's behind. They're making money and don't give a hoot.

    The only thing on their minds is making cash.

    those willing to front a larger investment get a larger say in the system.

    Riiiight. Isn't that the exact antithesis of what "cryptocurrency" is supposed to be about? This is how you put the control of the currency directly into the hands of the existing rich elites.

      Cryptocurrency is just about making money without working. Kind of letting your computer go to work for you. That's all there is*.

      So yes, much like in all possible ways money could be made throughout the ages, having money facilitates making money. I don't see why cryptocurrencies should be any different.

      * The whole "freedom" and "privacy" claim is just a scam. Cryptocurrencies aren't any of that, and certainly more traceable than the quaint old-fashioned coins: Nobody could trace a coin, a medieval pouch of gold coins was universal, stable and totally untraceable...

    tax on carbon

    Tax crypto for carbon emissions to the point where mining is not profitable.

    The effects of man made pollution are all too apparent

    and can't be ignored for profits created by something as worthless as crypto.

    Erm, the real problem is the continuing worship of fossil fuels by the uncaring followers of the Exxon/Peabody/Koch axis. And those who believe as NASA scientist Roy Spencer “Earth and its ecosystems—created by God’s intelligent design and infinite power and sustained by His faithful providence—are robust, resilient, self-regulating, and self-correcting”

      Seems I upset the uncaring followers of the Exxon/Peabody/Koch axis or one of those who believe as NASA scientist Roy Spencer

    Ban it from the planet

    The difficult question about solar power satellites was always how thd power that paid for them, and an orbital infrastructure around them, was to get to the planet.

    Use it up there. Ship the data.

    Make use of power within Earth's atmosphere, hydrosphere, lithosphere illegal, watch as had panels dread.

    If they'd like to drop inward a little - more sunlight, less eclipses - then thry could cluster around L1 and marginally decrease Earth's insolation helping to counter existing trouble from prior burning.

    A few implementation details, but the market I'm told will work such things out.
