Bitcoin miners seek alternative energy sources to cut costs
During the 2021 bull market, many large mining companies took on massive loans to buy equipment and the proper infrastructure required to mine cryptocurrency. Yet the collapse of crypto exchange FTX and Celsius left many of these companies filing for bankruptcy.
The current bear market, coupled with high Bitcoin network hash rates and low profits, has yet again left the crypto industry wondering if miners will be able to recover from losses. While this remains questionable, it’s become evident that mining companies today are focusing more on alternative energy resources to cut costs, ensure profits and, in some cases, reduce their environmental impact.
Alternative energy sources used by miners
Steven Lubka, managing director for Bitcoin-focused financial services company Swan Bitcoin, told Cointelegraph that while the average rate to mine a single Bitcoin (BTC) is around $26,000, mining companies focused on renewable energy sources are seeing rates between $5,000 and $15,000 per BTC.
A spokesperson for Riot Blockchain, a United States-based publicly traded Bitcoin mining company, told Cointelegraph that wind and solar energy generated across Texas has helped Riot ensure some of the lowest costs to mine crypto. “As stated in our Q2 investor deck, it costs Riot $8,389 to mine 1 Bitcoin,” he said.
Kent Halliburton, president and chief operating officer of Sazmining — a hosted Bitcoin mining provider — told Cointelegraph that the biggest expense for mining has always been electricity:
“Bitcoin miners are naturally incentivized to find the lowest-cost power. Excess electricity is the lowest priced. With renewables, there is often excess electricity, which makes it a perfect fit for Bitcoin mining.”
Halliburton added that independently sourced data from the Bitcoin Mining Council shows that the Bitcoin network may indeed be one of the most sustainable industries. According to the source, 59% of mining operations are carbon-free and growing at a rate of nearly 4.5% per year.
“All of our mining operations in Wisconsin and Paraguay are utilizing excess hydroelectricity,” he said.
The shift to alternative energy sources seems to be a trend for miners thinking about long-term success. Phil Harvey, CEO of crypto mining infrastructure provider Sabre56, told Cointelegraph that the company is currently working with dozens of mining companies to get machines set up across Sabre56’s three facilities located in Wyoming and Ohio.
Harvey explained that Sabre56’s facility in Gillette, Wyoming — known as “Bonepile” — hosts nearly 2,200 mining machines that are powered by a combination of energy sources, including a material contribution from renewable energy. The 5,200-square-foot site draws on Basin Electric’s mixed energy portfolio. According to Basin Electric’s website, this includes 24% wind, 0.6% recovered energy and 4.3% hydro, which adds up to 28.9% renewables.
Harvey said, “The machines at our Bonepile site consist of a mixture of MicroBT Whatsminer M50s and Bitmain Antminer S19s. In terms of the site design and methodology, we leverage a forced-air design, meaning air is forced into the facility to cool the machines.”
According to Harvey, the Bonepile facility is designed to ensure surplus air provision. Harvey explained that this method reduces overheating and strain on the mining equipment while also allowing the miners to naturally exhaust hot air through overpressure.
“This is different from the standard design widespread in the mining industry, which is often extracting the hot air with an additional mechanism while not having a system in place to aid air into the facility,” he remarked.
OceanBit, a company developing renewable energy platforms using ocean thermal sources, is taking a different approach. Michael Bennett, co-founder of OceanBit, told Cointelegraph that the company is integrating Bitcoin mining into its ocean thermal energy power plant design. “This will allow us to balance variable loads, deliver power faster to offshore operations, and monetize excess energy to improve plant profitability,” he explained.
According to Bennett, ocean thermal energy is the largest untapped energy source on the planet. “It’s a base load source of renewable energy, like hydro or geothermal, but uses the temperature difference in ocean water to generate electricity.”
Bennett believes Bitcoin is the missing piece needed to scale the energy source to global adoption since it solves a number of ocean thermal energy conversion (OTEC) commercial challenges.
Nathaniel Harmon, co-founder and CEO of OceanBit, elaborated, “The byproduct of OTEC generation process is four degrees Celsius cold water, which makes it ideal for cooling ASICs, while the byproduct of ASICs is low grade heat, which makes it ideal to use in the OTEC process. The combination increases the efficiency while decreasing the cost of both.”
Bennett shared that OceanBit plans to unveil its R&D power plant in Hawaii in 2024.
Some alternative energy sources are controversial
Pennsylvanian crypto mining company Stronghold Digital Mining is using coal refuse to power its mining operations.
This refuse — also known as gob, culm or boney — is the result of the refining process of coal mining. These unrefined bits of coal mixed with shale, slate or other impurities are piled on thousands of acres of abandoned mine lands in Pennsylvania.
Greg Beard, CEO of Stronghold Digital Mining, told Cointelegraph that his firm is working with the Pennsylvania Department of Environmental Protection and local environmental authorities to clean up piles of waste coal and use them to power Bitcoin mining operations.
He said, “Acid mine drainage from these piles is one of the largest sources of water pollution in Pennsylvania. The waste piles have also been catching fire for decades by way of spontaneous combustion, releasing toxic pollution into the air. Stronghold converts the coal refuse into power by way of specialized facilities and then either supplies the power to the local grid or uses the power to mine Bitcoin.”
“Bitcoin mining is required to continue the waste coal cleanup activities, making it a much more efficient operation than miners seeking out power sources,” added Beard.
While this does provide a method of cleaning up the tons of coal refuse, from an environmental perspective, it also poses something of a Catch 22.
The special plants that can use refuse coal are still burning hydrocarbons. The Pennsylvania arm of the Energy Justice Network project has even contended that refuse coal-firing plants pollute more than new coal plants.
Stronghold itself further came under the scrutiny of environmental groups when it applied for a permit to burn tire-derived fuel at its Panther Creek plant.
Clean Air Council activist Russell Zerbo recently said on a podcast that the plant “uses the electricity it produces to generate cryptocurrency; rather than selling that electricity to the energy grid, the plant should be completely repermitted as a solid waste incinerator that would be subject to increased air pollution monitoring requirements.”
Challenges for miners may hamper adoption
While it’s notable that crypto mining companies are using alternative energy sources, certain challenges could hamper adoption. Halliburton claimed that misinformation regarding alternative energy sources is common:
“Local populaces may throw-up roadblocks because they don’t realize that Bitcoin miners are providing a net benefit to their local communities through job creation and monetizing wasted or excess electricity. Electricity is also misunderstood; it’s extremely expensive to store, and if electricity is not utilized or stored when it’s generated, it gets wasted — quite literally put into the earth.”
Moreover, the challenges that come along with using renewable energy are also evident. Harvey mentioned that the altitude of Gillette, Wyoming results in much thinner air quality. As such, the machines at Sabre56’s Bonepile facility can struggle with pulling in enough air required for cooling.
Then comes the challenge of thermal pollution, as hot air is released into the atmosphere from the mining machines, which Cointelegraph witnessed firsthand at the Bonepile site in Wyoming. Given this, some mining companies are finding unique ways to reuse heat production. For instance, Genesis Digital Assets uses hot air produced by mining equipment to grow vegetables in the Nordic regions.
All things considered, the future of mining operations will likely rely on renewable sources. Margie Feng, head of marketing at Bitmain — a leading producer of crypto mining equipment — told Cointelegraph that the company has shifted gears and is currently working hard on promoting hydro-cooling technologies, as she believes that demands for this type of equipment will only grow in the future.
Feng added that Bitmain has found that almost a quarter of all Bitcoin miners use water to power their setups, while wind and nuclear are the second- and third-biggest contributions, respectively.
In early March, a Truth Social post by President Donald Trump promoting a “Crypto Strategic Reserve” went viral in the United States.
However, within hours of its going up, the post backfired on one of Washington, D.C.’s most well-connected lobbyists, Brian Ballard.
Truth Social Post Drama
According to a report from Politico, the idea for the post came from a staff member at Ballard’s lobbying firm who had spoken to Trump several times during a weekend donor event at Mar-a-Lago. She allegedly urged the president to back the crypto industry publicly and even suggested the language he would use.
Unknown to Trump at the time, Ripple, whose native XRP token was mentioned in the message, was a client of Ballard’s firm. CEO Brad Garlinghouse has made no secret of his desire to see XRP included in a proposed digital asset reserve.
Once the President learned of the connection, he was furious. “He is not welcome in anything anymore,” Trump reportedly told White House associates later that month, referring to Ballard.
As a result, staff were allegedly quietly directed to avoid meetings with him, effectively freezing him out of the West Wing.
Since Trump’s return to power, Ballard Partners has gained 130 new customers. The firm earned $14 million in the first three months of 2025, more than three times what it made in the same period last year.
However, some people in Trump’s circle now believe the influence peddler has gone too far. According to Politico, they think he uses his past ties to the President and his team to get more clients, even though those relationships may not be as close as he claims.
“One way to get yourself in the doghouse is for the President to think you are trading on his name,” one Trump ally told the media outlet, adding that the lobbyist overstates his “importance and value.”
Ballard Denies Accusations
In a statement to the media outlet, the 65-year-old rejected the criticisms and denied that he has been sidelined. “I have never touted my relationships with people in the West Wing to try to win clients,” he noted.
Regarding the Truth Social incident, someone from his team said they never tried to trick Trump with the message. Despite this, the situation seems to have caused Ballard some trouble with his business. A few of his clients have reportedly begun seeking alternative routes to gain access to the President and his advisers.
After opening his Washington office in 2017, Ballard quickly became one of the city’s most successful lobbyists. He is a well-known figure in Trump’s world, having helped raise tens of millions of dollars for the politician’s campaigns.
He also used to represent the Trump Organization, and his firm also employed two of the President’s close allies, Susie Wiles and Pam Bondi.

There are certain altcoin season vibes going on in the crypto market over the past weeks, as many representatives have marked notable price surges.
The trend is led by none other than the largest of them all – Ethereum, which has soared by another 8% in the past day, and trades well above $2,500.
ETH’s Roll Continues
ETH’s price plunged hard just over a month ago as it dropped to its lowest levels in over a year on April 9 at $1,400. It managed to bounce off in the following weeks but still struggled to reclaim $1,800 decisively. After the latest positive macro developments and the Pectra upgrade, its price finally started to climb hard.
On a daily scale, ETH has soared by nearly 9%, but its weekly surge is a lot more impressive – almost 40%. This has put its price tag at well above the psychological resistance of $2,500.
Many altcoins have followed suit with notable price increases as well. DOGE is in a league of its own from the larger ones, having surged by over 16% and now trading above $0.24. ADA, AVAX, LINK, SHIB, HBAR, TON, and PEPE are other impressive examples.
PI, UNI, and NEAR have also had double-digit price pumps over the past day, while LEO is among the few in the red.
The total crypto market cap has added another $70 billion and is up to $3.470 trillion on CG.
Bitcoin Back to $104K
Although BTC is still in the green on a daily scale, its increase is a lot more modest. BTC has jumped by less than 1% and trades above $104,000 after it was stopped at $105,000 earlier.
On a weekly scale, though, bitcoin has jumped by almost 9%. It finally managed to break through the $100,000 barrier this week for the first time in over three months.
However, its dominance over the alts has taken a big hit. Recall that the metric was riding high at roughly 62% just until several days ago but has dropped to under 60% as of now.
Its market cap, on the other hand, continues to increase and is up to $2.070 trillion on CG.

MyStonks Launches Industry-Leading On-Chain U.S. Stock-Token Marketplace with 100% Custody Backing
[PRESS RELEASE – New York, United States, May 10th, 2025]
MyStonks.org, a decentralized trading platform, announced the official launch of a fully custody-backed, on-chain U.S. stock token marketplace in the crypto industry. Cryptocurrency users can purchase U.S. stocks on MyStonks. Global asset management giant Fidelity provides custodial services for platform users, with an initial custody asset total of $50 million.
MyStonks has successfully established a complete operational cycle that links U.S. stock assets under Fidelity Custody to the Base blockchain for token minting and burning. Users can initiate purchases of Stonks100 stock tokens on MyStonks by transferring USDC or USDT from their self-custodied crypto wallets. Upon confirmation, MyStonks converts these stablecoins into USD and purchases the corresponding stock shares. These are then tokenized 1:1 into ERC-20 tokens via Base smart contracts. For example, when buying Apple shares, users receive AAPL.M tokens minted by MyStonks.org, representing the exact number of shares held. Token pricing utilizes Chainlink oracles.
If users wish to redeem their stock tokens, they can initiate a sell request for AAPL.M or other supported assets directly from their wallets. MyStonks will then convert the tokens back into stablecoins and burn the equivalent tokens in a 1:1 ratio.
To ensure the security of user assets, MyStonks has partnered with Fidelity, which provides custody services (Fidelity Custody) for platform users’ U.S. stock holdings.
According to a custodial statement dated April 29, 2025, Fidelity Custody holds over $50 million in U.S. equities ($50,473,199.00) on behalf of MyStonks Holding Limited. The initial batch of 95 tokenized equities includes major names such as AAPL, AMZN, DIS, GOOGL, META, MSFT, NFLX, and NVDA, each of which is mirrored on-chain by its respective token.
A representative from MyStonks explained that when users purchase U.S. stock tokens on the platform, the corresponding stocks are managed by Fidelity Custody, ensuring the authenticity, compliance, and auditability of assets. Through integration with Fidelity Custody’s infrastructure, MyStonks has achieved a seamless connection between on-chain tokens and off-chain stock assets.
As a trusted institution in TradFi, Fidelity plays a key role in safeguarding asset security and compliance, making it an important partner for MyStonks in the tokenization of stock trading.
Additionally, MyStonks has upgraded its on-chain trading security and user experience. When users initiate buy or sell orders, the platform executes the corresponding operations on the blockchain, including cross-chain asset management, real stock transactions, and the minting or burning of tokens. The entire process is transparent, traceable, and decentralized, enabling users to purchase U.S. stocks in a fully digital and tokenized manner.
All trading operations are governed by smart contracts to ensure immutability and auditability. A Decentralized Identity System (DID) safeguards account uniqueness and prevents fraudulent transactions. Core smart contracts have undergone security audits and are modularly designed to isolate risk. According to MyStonks.org, off-chain fund transfers require multisignature (multisig) wallet authorization to avoid single points of failure. Cross-chain asset movements are executed through audited protocols. Additional protections include a time-lock mechanism for transaction confirmation and HTTPS/HSTS enforcement for frontend encryption.
New user experience upgrades include support for on-chain limit orders, improved wallet connectivity, a refined user account dashboard, and optimized UI layouts.
“The launch of the Stonks100 tokenized U.S. stock marketplace marks an important milestone in our ongoing journey of innovation. As we continue to expand access to tokenized equities, our focus remains on offering secure, professional, and transparent trading infrastructure. We believe MyStonks users and our global community will grow alongside us as we push the boundaries of decentralized finance,” a MyStonks.org representative said.
About MyStonks.org
MyStonks.org is a decentralized crypto asset trading platform born out of a Community Takeover (CTO) effort by the Stonks community. It is an industry-leading platform to offer fully custody-backed, 1:1 tokenized U.S. equities on-chain. MyStonks aims to become the decentralized “NASDAQ” of the crypto world—supporting new token projects and reshaping the DeFi landscape for healthier market growth.
About the Stonks Community
The Stonks community draws inspiration from the GameStop ($GME) movement and the ethos of crypto resistance.
