Bitcoin power, Bitcoin is an energy hog. Where is all that electricity coming from?

The bitcoin network consumes vast amounts of electricity.

Some researchers say most of it comes from wind, solar, and hydroelectric power. A June paper in the journal Joule estimated that annual carbon dioxide emissions from the bitcoin network are as high as It also accounts for 0. But another recent study by CoinSharesa cryptocurrency asset management and analysis firm, found that the majority of the electricity used by bitcoin actually comes from clean sources, like wind, solar, and hydropower.

Bitcoin consumes more energy than Switzerland, according to new estimate

CoinShares says bitcoin network gets Analysts also warn that the same factors that pushed miners to use clean energy could one day lead them to back to dirty fuels. The CoinShares study also points to a broader problem for how renewable energy is currently deployed around the world: Many renewable power generators are so poorly located and underused that mining bitcoin has become the only viable use for that electricity.

  • How Much Power Does It Take to Create a Bitcoin?

Why bitcoin needs so much power Even though bitcoin solely exists in digital zeroes and ones, the computers that run the network are huge energy hogs. According to the bitcoin energy consumption tracker at Digiconomistbitcoin currently consumes Since there is no central bank or authority governing the bitcoin power, the bitcoin network regulates itself through a distributed accounting system known as blockchain.

In blockchain, every bitcoin transaction is tracked in a public bitcoin power spread across thousands of computers. These transactions are grouped into blocks. The bitcoin network creates an incentive for people to contribute computing power to verify transactions by awarding bitcoins to a miner who verifies a block currently Blocks are added to the blockchain roughly every 10 minutes.

But mining is competitive, with only one miner winning the award per block.

Over time, the calculations needed to verify a block get more difficult and the bitcoin award shrinks. The price is also unstable.

The Last Word on Bitcoin’s Energy Consumption

These factors have created an arms race to develop better computer hardware to more rapidly verify transactions and a push to devote ever-increasing amounts of electricity to the task. So miners really, really want to save as much on their electricity bills as possible.

The quest for the cheapest kilowatt has led miners to set up shop in remote regions of China and Mongolia. Bitcoin mines have gone up in rural Washington state.

The hunt for cheap power has even led to cases of electricity theft. A map showing the bitcoin power bitcoin mining regions around the world.

Since the network is spread all over the world, bitcoin miners often want to remain anonymous and keep their operations opaque. Another factor is that the computing make money on irecommend miners use, known as an application-specific integrated circuit ASIChas been getting more energy efficient over time. But mining operations are continually deploying more of them.

The power grids miners draw on are also changing over time and can change in their fuel sources between seasons. That means a local utility could be getting cleaner or dirtier over time, and if more fossil fuels are coming online to meet the demand, that would lead to more greenhouse gas emissions.

In so doing, the CoinShares team found that bitcoin miners were using a disproportionate share of renewables. This is why you see miners flock to regions where high-powered renewables are abundant. So bitcoin miners, who care more about electricity costs than location, happily moved into renewable-powered rust bitcoin power around the world.

Does Bitcoin Waste Energy?! Pomp explains

Governments have had mixed reactions to the rise of cryptocurrencies like bitcoin and their rapacious demand for electricity. In Quebecthe government is offering discounted electricity to lure in miners to boost the economy. Meanwhile, China is weighing an outright ban on cryptocurrency mining because it sees miners as scofflaws that are wasting resources and damaging the environment.

Bendiksen said bitcoin mining is making use of energy resources bitcoin power would otherwise go to waste and that renewable power mitigates its environmental footprint. He noted that its estimate of renewable energy use in bitcoin mining is out of line with other calculations.

A report from the University of Cambridgefor example, found that while the majority of bitcoin mining facilities drew on renewables to some extent, the average share was just 28 percent. In a separate paper published in Joule in April, de Vries explained that even the renewables being used for bitcoin mining have their own consequences.

Hydropower in particular has huge regional environmental effects and sometimes has bitcoin power be backed up by fossil fuels.

And since miners are concerned about energy costs above all else, a glut in coal, oil, or natural gas could make burning them much more attractive. Another emerging concern around bitcoin is the electronic waste. Bitcoin mining hardware is leading to a growing volume of electronic waste. Another price spike could push energy use even higher.
