Bitcoin miners align with fossil fuel firms, alarming environmentalists

Bitcoin is an energy beast. The Cambridge Bitcoin Electricity Consumption Index looks at available data on bitcoin to determine its energy usage. It takes a best-case scenario where all miners use the most energy-efficient equipment available, and a worst-case scenario where the opposite is true to the extent where miners can still make a profit based on electricity costs.

The best-guess scenario, which assumes miners will use a mix of hardware somewhere between the two, makes for shocking reading. Bitcoin uses around The machines solve a computational problem to prove that it completed some work before a transaction is accepted, a problem that varies in difficulty and ensures that the network remains protected from people trying to manipulate the network.

All this is necessary because, unlike a central processing system like Visa, bitcoin is designed to be decentralized. It does not require its users to place their trust in a central server or bank. While practically anyone can join the network and start mining, the electricity usage means it needs to be worthwhile for the miner if they want to make a profit from the resultant bitcoins.

That helps the researchers to understand what sort of machines they might be using, and whether they may switch to dedicated machines specifically designed to solve these bitcoin puzzles more efficiently. The electricity research chimes with findings from others.

Researcher Alex de Vries went viral in December , when he warned that the cryptocurrency was using around De Vries later announced in March that the cryptocurrency used around While the global banking industry used terawatt-hours per year to process transactions, de Vries noted that it ultimately used 0.

Bitcoin, on the other hand, used to kilowatt-hours per transaction. Mike Brown. To put that in perspective: It uses around the same amount of energy as the country of Switzerland , which uses The amount of energy used by household products on standby in American homes could power bitcoin for four years.

Bitcoin-Mining Power Plant Raises Ire of Environmentalists

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.

Today, Bitcoin consumes as much energy as a small country. the makeup of different energy sources used by the computers mining Bitcoin.

What if you could substitute a renewable battery powered motor for the internal combustion engine just twelve years after its invention? At minimum, we would not be faced with the challenge of limiting greenhouse gas emissions. For all of the benefits the internal combustion engine has brought humanity, its environmental consequences are not among them. An equally consequential technology—Bitcoin BTC —in its twelfth year of existence, is being adopted at an unprecedented pace. As it matures, its energy use, among other things, will only receive greater scrutiny. Operating the Bitcoin network globally uses as much energy as Washington State, which amount to less than one half of one percent of total global energy use. It is all the more essential because with effort, Bitcoin mining can be done with clean energy sources and by relying on waste energy streams. But to facilitate a movement toward more climate-friendly Bitcoin mining, more people must appreciate why Bitcoin is consequential. Bitcoin enables these people to maintain and control their hard-earned value.

Bitcoin and the environment

is bitcoin mining wasted computing electric power

Bitcoin has already used more power so far this year than it did in all of , a new study has suggested, as the debate on the impact of cryptocurrency mining on the environment heats up. Bitcoin is set to use 91TWh of energy by the end of this year, according to a Bloomberg report , which noted this is as much energy as Pakistan. Last year, Bitcoin was estimated to have consumed about 67TWh of electricity. While tracking how much energy Bitcoin mining uses is difficult, the trend is clear.

An obstacle to large-scale bitcoin mining is finding enough cheap energy to run the huge, power-gobbling computer arrays that create and transact cryptocurrency.

Why You’re Paying Bitcoin’s Energy Bill

As new miners join the fray and the Bitcoin network continues to grow, so too does its energy usage. As of mid-July, a single bitcoin transaction required On an average day , , bitcoin transactions are sent over the network. Often referred to as the new gold rush, it can be hard to comprehend how something with no physical manifestation can be so resource-intensive. These miners must compete against each other to win the right to add the next block to the blockchain and earn rewards. The competitive structure results in a lot of wasted energy as only one miner can add a new block every 10 minutes. To maintain a competitive advantage over other miners, many larger operations are forced to scale up or upgrade their equipment.

China appears to have missed its target for cutting energy intensity set for , according to Reuters calculation based on official data.

Is Cryptomining Harming the Environment?

Mining for bitcoin generates substantial electronic waste that "represents a growing threat to the environment", according to a recent study. A co-author of the report told AFP on Friday that the average life cycle of the powerful computers used to unearth the units of the world's leading cryptocurrency was only 1. Alex de Vries noted that this was "extremely short compared to any" other electronic devices such as iPhones.

Bitcoin Does Not Waste Energy

Cryptocurrency mining has a large carbon footprint. The process requires a computer process that consumes a massive amount of electricity. Other than that, the mining system also requires the latest, fastest, most energy-efficiency computer chips and discard older ones. The average lifespan of a bitcoin mining chip is just a year. The consequence is the annual volume of e-waste from bitcoin mining globally is about 30, metric tons. This amount is almost as much as the e-waste produced by Netherlands in a year.

Four years ago, the Scrubgrass power plant in Venango County, Pennsylvania, was on the brink of financial ruin as energy customers preferred to buy cheap natural gas or renewables. Then Scrubgrass pivoted to Bitcoin. Today, through a holding company based in Kennerdell, Pennsylvania, called Stronghold Digital Mining that bought the plant, Scrubgrass burns enough coal waste to power about 1, cryptocurrency mining computers. These computers, known as miners, are packed into shipping containers next to the power plant, the company stated in documents filed with the U. Securities and Exchange Commission ahead of its initial public offering.
