One Bitcoin Transaction Now Uses As Much Energy As Your House In a Week (vice.com)

Long-time Slashdot reader SlaveToTheGrind quotes Motherboard: Bitcoin's incredible price run to break over $7,000 this year has sent its overall electricity consumption soaring, as people worldwide bring more energy-hungry computers online to mine the digital currency. An index from cryptocurrency analyst Alex de Vries, aka Digiconomist, estimates that with prices the way they are now, it would be profitable for Bitcoin miners to burn through over 24 terawatt-hours of electricity annually as they compete to solve increasingly difficult cryptographic puzzles to "mine" more Bitcoins. That's about as much as Nigeria, a country of 186 million people, uses in a year.

This averages out to a shocking 215 kilowatt-hours (KWh) of juice used by miners for each Bitcoin transaction (there are currently about 300,000 transactions per day). Since the average American household consumes 901 KWh per month, each Bitcoin transfer represents enough energy to run a comfortable house, and everything in it, for nearly a week.

    The energy spent *MINING* a bitcoin is not at all close to the energy spent *TRANSACTING* a bitcoin. Why is this even a metric?

    It is ironic that in a era where most people are talking about:

    * Energy efficiency
    * Energy independence
    * Emissions reduction
    * Green power production

    we are racing to consume [waste] tons of energy to produce "currency" which doesn't actually produce any goods or services. Imagine consuming megawatts of energy just to produce currency that could then be used to later buy things like, perhaps, more megawatts of energy. Seems insane.

  3. I pay for my house energy usage in bitcoins by hxnwix · · Score: 5, Insightful

    I pay my power bill using bitcoins. I noticed that I have to build out exponentially more bitcoin mining infrastructure every month, but I thought that was normal. I guess I should have realized something was amiss when we built the 60-acre data center. Anyhoo, the 3,600-acre data center will be sufficient, I am confident.

    You mean just-like-Trotsky-ites ... pimping the pauper with the words THEFT-AGENDA substituted for the word RICH.

    Or just like the fascists selling a middle class tax cut on the tired old theory that when we give the lion's share of that tax cut to the big corps and the 1% that it will all trickle down to the middle class, eventually. Yes, Trump's economic adviser, Gary Cohn, used the phrase trickle down in an interview just a couple of days ago.

    When the rich run the system, Trump's promises notwithstanding, they rig the system to make themselves even richer, so, yes, you could call it a theft agenda.
