“Everyone I talk to now is talking about carbon neutrality,” said Paul Prager, the chief executive of TeraWulf. “The language has absolutely changed.”

But financial priorities and technological barriers in the crypto mining industry, which includes more than a dozen publicly traded companies like Argo, are preventing a complete shift to renewable power. In late 2020, Marathon, one of the largest publicly traded mining companies, started mining Bitcoin at a coal-powered plant in Montana, citing the easy access to cheap energy.

In Illinois, the cryptocurrency mining company Sangha Systems has repurposed an old steel mill in the town of Hennepin. Sangha is run by a former lawyer, Spencer Marr, who says he founded the company to promote clean energy. But about half the Hennepin operation’s power comes from fossil fuels.

“It was a compromise we had to make,” Mr. Marr said. “It was a means to an end that allowed us to establish ourselves as a company.”

In recent months, Texas has become a hot spot for crypto mining, attracting more than two dozen companies. The state has an unusual incentive structure that’s well suited to the nascent industry: the Texas grid operator offers what amounts to a discount to companies that can quickly unplug when electricity demand spikes statewide, allowing energy to flow to ordinary homeowners. Many crypto mines can turn on or off in seconds, allowing them to take advantage of the incentive with minimal inconvenience.

That deal was part of the attraction for Argo, a London-based company founded in 2017 that runs two other mines in Quebec, using mostly hydropower. Mr. Wall said Argo was also drawn to the ample green energy in West Texas. The facility outside Lubbock will be connected to the western sector of the Texas energy grid, where about 85 percent of electricity comes from wind and solar infrastructure, including a set of turbines that sit practically next door to the Argo construction site.

But Mr. Wall can’t guarantee that Argo’s new center will have no carbon footprint. That would require bypassing the grid and buying energy directly from a renewable power company.

“A lot of those renewable energy producers are still a little bit skeptical of cryptocurrency,” he said. “The crypto miners don’t have the credit profiles to sign 10- or 15-year deals.”

In the future, he said, Argo plans to build its own solar panels on site in Texas and broker deals with local renewables companies to buy energy directly.

According to the study, the Bitcoin network’s use of green energy sources also dropped to an average of 25 percent in August 2021 from 42 percent in 2020. (The industry has argued that its average renewable use is closer to 60 percent.) That’s partly a result of China’s crackdown, which cut off a source of cheap hydropower. But it reflects fundamental economic incentives, too, said Alex de Vries, one of the authors of the Joule study. Renewable energy is an intermittent power source — the sun shines only part of the day, and wind speeds fluctuate considerably.

“What a miner is going to do if they want to maximize the profit is put their machine wherever it can run the entire day,” Mr. de Vries said.

Bitcoin’s ballooning energy use has long outraged environmentalists. But the criticism that made the strongest impression came from Mr. Musk, a longtime Bitcoin booster, who said on Twitter in May that Tesla, his electric car company, would no longer accept cryptocurrency payments because of the “increasing use of fossil fuels for Bitcoin mining and transactions.”

His tweet sent the mining industry into crisis mode. Michael Saylor, the chief executive of the software company MicroStrategy, which invests heavily in Bitcoin, got in touch with Mr. Musk to discuss the climate issue. A group of mining executives, including Mr. Saylor and Mr. Wall, later met with Mr. Musk over Zoom.

“He wanted to make sure that the industry is on the side of sustainability, and he gave us some coaching,” Mr. Saylor recalled. “His encouragement was: ‘Find out how clean is the energy, how sustainable is the energy. Figure out how much you’re using.’” (Mr. Musk did not respond to a request for comment.)

After the call, Mr. Saylor set up the Bitcoin Mining Council, a forum for the industry to share ideas and coordinate environmental strategy. One member, TeraWulf, has pledged to run cryptocurrency mines using more than 90 percent zero-carbon energy. It has two projects in the works — a retired coal plant in upstate New York fueled by hydropower, and a nuclear-powered facility in Pennsylvania.

The effort — partly a public-relations exercise, partly a genuine attempt to make the industry more sustainable — has intensified since last spring, when China began a crackdown on crypto mining, forcing some mining operations to relocate to the United States. A trade group called the Bitcoin Mining Council also formed last year, partly to tackle climate issues, after Elon Musk criticized the industry for using fossil fuels.

Crypto mining does not involve any picks or shovels. Instead, the term refers to a verification and currency creation process that is essential to the Bitcoin ecosystem. Powerful computers race one another to process transactions, solving complex mathematical problems that require quintillions of numerical guesses a second. As a reward for this authentication service, miners receive new coins, providing a financial incentive to keep the computers running.

In Bitcoin’s early years, a crypto enthusiast could mine coins by running software on a laptop. But as digital assets have become more popular, the amount of power necessary to generate Bitcoin has soared. A single Bitcoin transaction now requires more than 2,000 kilowatt-hours of electricity, or enough energy to power the average American household for 73 days, researchers estimate.

To achieve that, some miners are reviving broken-down coal plants, or using low-cost natural gas to power their computers. Last month, a study in the journal Joule found that Bitcoin mining worldwide may be responsible for about 65 megatons of carbon dioxide a year, comparable to the emissions of Greece.

Along a dirt-covered road deep in Texas farm country, the cryptocurrency company Argo Blockchain is building a power plant for the internet age: a crypto “mining” site stocked with computers that generate new Bitcoins.

But unlike other Bitcoin mining operations, which consume large quantities of fossil fuels and produce carbon emissions, Argo claims it’s trying to do something environmentally responsible. As Peter Wall, Argo’s chief executive, led a tour of the 126,000-square-foot construction site one morning this month, he pointed to a row of wind turbines a few miles down the road, their white spokes shining in the sunlight.

The new facility, an hour outside Lubbock, would be fueled mostly by wind and solar energy, he declared. “This is Bitcoin mining nirvana,” Mr. Wall said. “You look off into the distance and you’ve got your renewable power.”

Facing criticism from politicians and environmentalists, the cryptocurrency mining industry has embarked on a rebranding effort to challenge the prevailing view that its electricity-guzzling computers are harmful to the climate. All five of the largest publicly traded crypto mining companies say they are building or already operating plants powered by renewable energy, and industry executives have started arguing that demand from crypto miners will create opportunities for wind and solar companies to open facilities of their own.

The RNS mistakes are infuriating that’s for sure, hopefully they have got the message !!

I love a punt but even I wouldn’t pick the one with 3 legs and one eye even if it was a good price. More chance it turns up in one of their burgers than it wins a race.

But Chaebol has it hit that 5p you were on there telling them it was going to it a few months back - Playing your own book you naughty little John Campbell you ;)

Found that a touch unfair on Hive as im pretty sure (But stand to be corrected) They are one that are currently at the forefront of being green, but going forwards any that are not are going to find it hard to sustain/gather new institutional investment you would tend to think.

Not really Noob, That they are admitting they havent secured pretty much the most fundemental aspect for discovery is slightly worrying at best - Theyve had the best part of 9 months to get it sorted and if they havent as yet that should really raise eyebrows, Its always been a risk reward play for me so wasnt overly concerned when they didnt hit last year as thats the nature of the game and part and parcel of the risk and a little out of there hands, but if its true no rig is organised as of yet thats down to rank bad management as its in their control.

MrD,
Your one sick #'#',

Yes does seem to be turning a little, Lets hope the final pieces fit in nicely. I think from the recent RNSs and Uploads the news flow is being turned on again so that should help. Id imagine we will also get News as to what Perrys been up to shortly which again should help nudge us along - Think that video may have been a prelude to it. As ever though we do need Bitcoin to play ball ! GLA

Quick fingers ;-)

Think it was pretty much the top riser yesterday to on an up day - Not that the the usual suspect mentioned it. Strangely.

Think Tom Winniforth would be best advised to take a trip to a dentists, looking at them gnashes.

Yes mystery the Texas facility is looking great and In a month or so it should be churning out coins, been a hard **** slog the past 12 months but hopefully if Btc plays ball their foresight in building it will start to pay dividends on our SP.

Sorry on my phone "Should never be one or the other anyway"
