Nov 25,  · Bitcoin Miners Are Starving Entire Cities Of Electricity By RFE/RL staff - Nov 25, , PM CST SUKHUMI -- In the side streets and narrow . Jul 04,  · It means Bitcoin accounts for roughly percent of the world’s entire electricity consumption. That’s as much energy as all the tea kettles in the UK use . Jun 18,  · The bitcoin network consumes vast amounts of electricity. Some researchers say most of it comes from wind, solar, and hydroelectric power.

Bitcoin uses electricity

Bitcoin consumes more energy than Switzerland, according to new estimate - The Verge

In a blog post announcing the new index, the Cambridge Centre for Alternative Finance, which oversaw the work, makes the same observation. The lower bound is currently around 22 TWh while the upper bound is just under TWh. Though these figures may have changed since the time of publication. Regardless of the exact figures, the energy usage of Bitcoin is certainly eyebrow raising. The cryptocurrency also looks unwieldy in terms of day to day utility.

Because of this, the energy consumption of proof-of-stake is negligible compared to proof-of-work. Bitcoin could potentially switch to such an consensus algorithm, which would significantly improve environmental sustainability. The only downside is that there are many different versions of proof-of-stake, and none of these have fully proven themselves yet.

Nevertheless the work on these algorithms offers good hope for the future. Even though the total network hashrate can easily be calculated, it is impossible to tell what this means in terms of energy consumption as there is no central register with all active machines and their exact power consumption. This arbitrary approach has therefore led to a wide set of energy consumption estimates that strongly deviate from one another, sometimes with a disregard to the economic consequences of the chosen parameters.

The Bitcoin Energy Consumption Index therefore proposes to turn the problem around, and approach energy consumption from an economic perspective.

The index is built on the premise that miner income and costs are related. Since electricity costs are a major component of the ongoing costs, it follows that the total electricity consumption of the Bitcoin network must be related to miner income as well. To put it simply, the higher mining revenues, the more energy-hungry machines can be supported.

Note that one may reach different conclusions on applying different assumptions a calculator that allows for testing different assumptions has been made available here.

The chosen assumptions have been chosen in such a way that they can be considered to be both intuitive and conservative, based on information of actual mining operations. In the end, the goal of the Index is not to produce a perfect estimate, but to produce an economically credible day-to-day estimate that is more accurate and robust than an estimate based on the efficiency of a selection of mining machines.

The latter index was based on the alternative methodology provided by Bevand which is strongly advocated by Koomey , but failed to produce significantly different estimates. Apart from the energy consumption estimates, the resulting environmental impact in the form of carbon footprint has also been strongly contested by critics like Robert Sharratt and the company Coinshares. Specifically, Sharratt used the Coinshares mining report to argue that the network has limited environmental impact. This is an important omission, as it ignores that the carbon intensity of electricity bought in Sichuan China , where miners are primarily located according to Coinshares, is nowhere near as low as one might expect.

Of course, the Bitcoin Energy Consumption Index is also very much a prediction model for future Bitcoin energy consumption unlike hashrate-based estimates that have no predictive properties. At the moment January , miners are spending a lot more on electricity. This can happen after a significant drop in mining revenues where mining becomes generally unprofitable.

These transfers can be done with minimal processing cost, allowing users to avoid the fees charged by traditional financial institutions - as well as the oversight and regulation that entails. This means it has attracted a range of backers, from libertarian monetarists who enjoy the idea of a currency with no inflation and no central bank, to drug dealers who like the fact that it is hard but not impossible to trace a bitcoin transaction back to a physical person.

The Bank of England said earlier this year that it would join forces with other central banks to examine how Britain and other countries might use a central bank digital currency in the mould of bitcoin.

The move is partly a response to concern about oversight of private digital currencies, including Facebook's libra. The exchange rate has been volatile, making it a risky investment. The more electricity you burn, and the faster your computer, the higher your chance of winning the competition. The prize? This is a winner-takes-all game, where the prize is guaranteed to be paid to one, and only one, miner every 10 minutes.

The economic outcome of all of this is laid bare in a Credit Suisse briefing note published on Tuesday: the network as a whole will reinvest almost all the bitcoin paid out as mining rewards back into its electricity consumption.

At current prices for electricity and bitcoin, the bank calculates a maximum profitable power draw of bitcoin at around TWh — two-and-a-half times higher than its current rate. Any higher and the miner will lose money.
