A Bitcoin Boom Fueled by Cheap Power, Empty Plants and Few Rules

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 CoinShares , a 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. 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.

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 Digiconomist , bitcoin currently consumes Since there is no central bank or authority governing the currency, the bitcoin network regulates itself through a distributed accounting system known as blockchain. In blockchain, every bitcoin transaction is tracked in a public ledger 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. 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. Between 60 and 80 percent of bitcoin mining revenue goes straight back into paying for electricity.

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. 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 hardware miners use, known as an application-specific integrated circuit ASIC , has 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. Regions with high levels of renewable energy and low demand are often areas that saw local industries leave in recent years and subsequently experienced a population exodus.

So bitcoin miners, who care more about electricity costs than location, happily moved into renewable-powered rust belts around the world. Governments have had mixed reactions to the rise of cryptocurrencies like bitcoin and their rapacious demand for electricity. In Quebec , the 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 that 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 Cambridge , for 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 to be backed up by fossil fuels. Production of hydropower is high in the wet season during the summer months and low in the dry season during the winter months. 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. But mining bitcoins remains profitable, so the amount of hardware it uses and the quantity of electricity it inhales will continue to surge dramatically for years. Another price spike could push energy use even higher. Our mission has never been more vital than it is in this moment: to empower through understanding.

A bitcoin mining power plant secretly set up shop in Alberta. Now it's being forced to shut down

Bitcoin is on the verge of going mainstream, with some companies — and even countries — recognizing the cryptocurrency as legal tender. The market cap of Bitcoin now surpasses both Facebook and Tesla , and it also recently became the 13th largest currency in the world. In the real world, however, the surging investment in virtual currency is inflicting real world impacts — perhaps nowhere more acutely than Pennsylvania. As Bitcoin mining operations scour the globe for readily available electricity, previously dead or dying fossil fuel plants are being resuscitated and repurposed to power single-purpose supercomputers. The result is a tremendous amount of unnecessary carbon pollution. Rather than relying on a bank or other centralized institution to mediate financial transactions, Bitcoin and other cryptocurrencies promise to cut out the middleman. Ensuring the validity of those blocks is a decentralized process.

Canada: Tax Assistance

The Australian government has just recognized digital currency as a legal payment method. Since July 1, purchases done using digital currencies such as bitcoin are exempt from the country's Goods and Services Tax to avoid double taxation. As such, traders and investors will not be levied taxes for buying and selling them through legal exchange platforms. Japan, which legitimized bitcoin as a form of payment last April, already expects more than 20, merchants to accept bitcoin payments. Other countries are joining the bandwagon, albeit partially: businesses and some of the public organizations in Switzerland, Norway , and the Netherlands.

Why does Bitcoin need more energy than whole countries?

Bitcoin mining is designed to be similar to gold mining in many ways. Bitcoin mining and gold mining are both energy intensive, and both have the potential to generate a handsome monetary reward. Bitcoin mining is a highly complex computing process that uses complicated computer code to create a secure cryptographic system. Similar to the secret codes used by governments and spies, the cryptography used for mining generates Bitcoin, facilitates Bitcoin transactions, and tracks asset ownership of the cryptocurrency.

How to Mine Bitcoin? Bitcoin Mining

Get updates on the latest posts and more from Analytics Steps straight to your inbox. Digital money or a cryptocurrency, Bitcoin was established in the year by a person or a group of persons who go by the name of Satoshi Nakamoto. A cryptocurrency that works on the basis of peer-to-peer technology, Bitcoin is not sanctioned by any central authority or a bank but is traded on a public ledger. This public ledger is transparent and accessible to all those who trade in digital currency. An open-source platform where the currency is traded among those participating, Bitcoin is a global currency, unlike other currencies that are sanctioned by central authorities or governmental organizations.

When residents of an affluent estate community in Alberta started hearing noise from a nearby power plant, they didn't expect their complaints of sleepless nights would lead to a months-long investigation that would find a bitcoin mining operation had set up shop without approval. Now, Link Global, the company behind the site, is being ordered by the province's utility commission to shut down two plants until it can prove it's allowed to operate — a move the company says will cost jobs and cause the oil and gas infrastructure in which it operates to sit dormant. Jeff Kocuipchyk first started hearing the noise last fall. He's president of the Greystone Manor Community Association, a small neighbourhood located in Sturgeon County, about 10 kilometres from the northwest outskirts of Edmonton. It's just like a wave … but it's 10 times louder and times more annoying," Kocuipchyk said.
