Paraguay seizes 2,738 ASICs as power theft crackdown continues

Power-intensive crypto mining is controversial in Paraguay, where an attempt at crypto regulation was vetoed because of it.

Property containing 2,738 crypto mining units was seized in Salto del Guairá, Paraguay, after the National Electricity Administration (ANDE) detected an unmetered power connection in the area. There is a bill before the country’s senate to ban crypto mining and other crypto-related activities pending comprehensive legislation and assurances from the national power supplier.

ANDE used artificial intelligence and power distribution analysis to zero in on the electricity theft, which it estimated was worth 1.1 billion guarani ($146,000) per month. Five transformers were also seized on the property. Four criminal charges may be brought against the operators of the illegal operation.

At least two other actions against illegal crypto farms — one in Salta del Guairá — were carried out in Paraguay in May, although those raids had much more modest results. All the government actions involved multiple agencies, including the National Police.

Renewable energy Bitcoin mining company powers up in Sweden

Bitcoin mining lands another green energy data center as global powerhouse GDA sets up shop in Sweden.

Sweden has welcomed a hydro-powered Bitcoin (BTC) mining data center. 

Genesis Digital Assets Limited (GDA), a mining and data center company with over 400 MW of power generation worldwide has made a opened a new data center in Sweden, driven by the country's burgeoning renewable energy surplus.

The new operation is located in the far North of Sweden, where hydroelectric power dominates the grid.  Abdumalik Mirakhmedov, executive president and fouder of GDA, told Cointelegraph that the new data center is located near the Porjus Hydroelectric Power Station:

“Given the proximity to the hydroelectric power station, we expect all of our electricity consumption to be powered by renewable energy.”

The total capacity of the data center is approximately 8 MW and is expected to result in a hash rate of approximately 155 PH/s (peta hashes per second). GDA explained to Cointelegraph that there are 1,900 Bitcoin mining machines deployed in the Porjus data center.

As reported by Jaran Mellerud, a Business Developer at Luxor Mining, and a frequent Cointelegraph contributor, Sweden produces almost all of its electricity from nuclear and hydropower, particularly the north.

Mellerud, who hails from nearby Norway, explains that renewable energy is also abundant:

“Sweden is an electricity powerhouse, generating the fifth-most electricity per capita globally in 2021.

GDA’s strategic expansion is part of a broader trend in the Northern European Bitcoin mining landscape. Christian Anders, the founder of BT.CX, a Swedish Bitcoin exchange dating back to January 2012, told Cointelegraph that Bitcoin mining is not very common due to high energy prices.

However, the Nordics are a class apart, Anders told Cointelegraph:

“Sweden, Finland, and Norway have a surplus of energy and negative energy prices from time to time, and primarily renewable energy in the form of hydropower in a remote location which is hard to distribute.”

Untapped, stranded, and renewable energy are popular ingredients for Bitcoin mining as they tend to be the cheapest. Mirakhmedov explained, “Sweden also has abundant clean energy sources, which is an important factor we consider in our operations.”

Porjus is in the far north of Sweden where renewable energy is abundant.

Moreover, while sentiment among some Scandinavians is negative towards Bitcoin, Anders told Cointelegraph that energy companies are coming around to Bitcoin mining's utility: “The CEO of the largest energy producer in Sweden, Vattenfall, is pro-bitcoin mining, and its use case for grid balancing.” Stabilizing electricity grids with Bitcoin miners is also growing in the United States. 

Tim Carra, the head of Nordic at GDA, expounded the point in correspondence with Cointelegraph:

“With abundant energy sources, a pro-innovation environment, and a strong educational system that results in a great culture of innovation, we believe that Sweden is one of the best countries in the world where to mine bitcoin and expect to further invest in this beautiful region moving forward.”

GDA concentrates the majority of its power generation in Texas: one facility consumes 300 MW of electricity. The new Swedish operations complement a new GDA facility in South Carolina and demonstrate that there are still some attractive and untapped potential mining destinations around the world. Anders chimes in:

“There is also a market opportunity in Spain/Portugal which gets cheap energy from Africa and its domestic solar production where prices also are very cheap from time to time. BT.CX is working with renewable bitcoin miners to offer a way to offset your bitcoin holdings.”

As Anders alludes to, the generation of new Bitcoins consumes considerable amounts of electricity. The European Central Bank reports that Bitcoin mining has a significant carbon footprint.

Stats from the Cambridge Centre for Alternative Finance. Global energy consumtion is estimated at 25,000 terawatt-hours according to the IEA.

However, portrayed as an energy-guzzling and carbon-intensive industry, Bitcoin mining consumes just 149.95 Terawatt hours of electricity per year, or less than 0.7% of global energy, according to the Cambridge Center for Alternative Finance.

Meanwhile, renewable energy including hydro continues to dominate the global bitcoin mining energy mix. Neighboring Norway, for example, contributes roughly 1% of the Bitcoin hash rate and is 100% renewable, while the new GDA installation in Sweden is another green energy Bitcoin miner.

Ultimately, Anders concludes, “It's super cool that more miners are coming to the Nordic European countries to help us with this mission.”

Bhutan mines Bitcoin with hydropower since BTC price was $5,000

The Kingdom of Bhutan uses Himalayan rivers to generate energy used to mine Bitcoin, local reports reveal.

The Kingdom of Bhutan is bullish on Bitcoin (BTC). Following the revelation that the small Himalayan Kingdom has been quietly accumulating crypto, the country is also mining Bitcoin. Moreover, the country of less than 800,000 people leverages green energy to power its Bitcoin mining operations.

Known for its focus on “Gross National Happiness” and picturesque landscapes, Bhutan has found ways to harness its immense hydroelectric potential, which accounts for 30% of its gross domestic product.

First reported in an exposé in local Bhutanese news and followed by inquiries from Forbes, Bhutanese officials confirmed that mining began when the price of Bitcoin was around $5,000 in April 2019. The price per Bitcoin has since soared to roughly $28,000 per coin at the time of writing.

The Kingdom has reportedly explored partnerships to expand its mining operations further. Notably, it is negotiating with Nasdaq-listed mining company Bitdeer to secure 100 megawatts of power for a Bitcoin mining data center in Bhutan. This partnership would increase Bitdeer’s mining capacity by about 12%.

The scale of Bhutan’s mining operations remains a mystery, with little information available about the location, size and profitability of its mining farms. Some Druk Holding and Investments (DHI) employees have listed “crypto mining” as their tasks and skills on their LinkedIn profiles.

It is also unclear why the government chose not to disclose this project to its citizens or international partners. However, it is known that the state-owned holding company DHI has invested millions of dollars in cryptocurrency holdings, with the funds managed on behalf of its people.

Although mainstream media would indicate the contrary, Bitcoin mining is the world’s cleanest industry, with more than 50% of its energy sources being renewable or clean energy. Bitcoin mining advocates, such as MicroStrategy chairman Michael Saylor, explain that “99.92% of carbon emissions in the world are due to industrial uses of energy other than Bitcoin mining.“ Due to cheap, abundant hydroelectric power, DHI reported that Bhutan is an ideal destination for mining Bitcoin.

Bitcoin mining brings more than money to this East African country

A Bitcoin mining project in a remote corner of Malawi, a landlocked country in southeastern Africa, connects more families to the grid while delivering economic empowerment to an impoverished region.

A Bitcoin (BTC) mining project that taps into clean, stranded and excess hydro energy in Malawi has picked up steam. The company behind the project, Gridless, shared that there are now “1600 families connected to this remote hydro mini-grid in the mountains of southern Malawi.”

The project exploits 50 Kilowatt (kW) of stranded energy to test out as a new Bitcoin mining site. Erik Hersman, CEO and co-founder of Gridless, told Cointelegraph that while it’s a brand new mining project, the “Impact was immediately felt.”

“The power developer had built these powerhouses a few years ago, but they weren’t able to expand to more families because they’re barely profitable and couldn’t afford to buy more meters to connect more families. So our deal allowed for them to immediately buy 200 more meters to connect more families.”

Bitcoin miners are flexible but energy-hungry clients. They are a plug in and play solution for sources of excess energy around the world. In Malawi, the miners run off environmentally-friendly hydropower.

In Hersman's words:

“The environmental footprint is quite light as it is run off a river. And the Bitcoin mining didn’t change any of that.”

It’s Gridless’ second project in Sub-Saharan African to date. Late last year, a mining project in Kenya connected a remote community using excess hydropower.

The environment aside, the Bitcoin mine brings economic empowerment and job opportunities to Malawi. Hersman explained that electricity load shedding is common in Malawi, but the 1600 families using the hydropower source do not have any power issues:

“It’s always amazing to me to see how useful and valuable mini-grids are to the community. It [Bitcoin mining] immediately changes the education, healthcare, business, logistics, and wealth of the community where they go in.”

Obi Nwosu, CEO of Fedimint and a Board Adviser at Gridless also shed light on the story, explaining that the project in "Malawi is one more in a line of what I expect to be many examples over the coming years."

“As usual, these are modest people rolling up their sleeves and helping talented, local engineers do what they do best. The project brings power as well as financial and economic freedom to many.”

Bitcoin miners tapping into stranded energy while empowering local communities is a growing trend in 2023. From El Salvador’s promise of geothermal Bitcoin mining to balancing the grid load and sustaining jobs for local communities in Canada– there is a “Torrent of opportunities coming their way,” Nwosu explains.

Michael Saylor has described Bitcoin mining as “the ideal high-tech industry to put in a nation that has plenty of clean energy but isn’t able to export a product or produce a service with that energy.” It’s an accurate summation of the project in Malawi.

Ultimately, this type of Bitcoin mining projects is more akin to a partnership. Hersman sums it up: “We work with the power producer, and they work to keep the power price affordable and all of their employees are from the community too, providing jobs for everything from security to linesmen to operations.”

Nuclear and gas fastest growing energy sources for Bitcoin mining: Data

Some governments can negatively impact Bitcoin's environmental footprint by banning BTC mining, according to new data from Cambridge.

The electricity mix of Bitcoin (BTC) has drastically changed over the past few years, with nuclear energy and natural gas becoming the fastest growing energy sources powering Bitcoin mining, according to new data.

The Cambridge Centre for Alternative Finance (CCAF) on Tuesday released a major update to its Bitcoin mining-dedicated data source, the Cambridge Bitcoin Electricity Consumption Index (CBECI).

According to the data from Cambridge, fossil fuels like coal and natural gas made up almost two-thirds of Bitcoin’s total electricity mix as of January 2022, accounting for more than 62%. As such, the share of sustainable energy sources in the BTC energy mix amounted to 38%.

The new study suggests that coal alone accounted for nearly 37% of Bitcoin’s total electricity consumption as of early 2022, becoming the largest single energy source for BTC mining. Among sustainable energy sources, hydropower was found to be the largest resource, with a share of roughly 15%.

Despite Bitcoin mining significantly relying on coal and hydropower, the shares of these energy sources in the total BTC energy mix have been dropping over the past several years. In 2020, coal power powered 40% of global BTC mining. Hydropower’s share has more than halved from 2020 to 2021, tumbling from 34% to 15%.

In contrast, the role of natural gas and nuclear energy in Bitcoin mining has been notably growing over the past two years. The share of gas in the BTC electricity mix surged from about 13% in 2020 to 23% in 2021, while the percentage of nuclear energy increased from 4% in 2021 to nearly 9% in 2022.

According to Cambridge analysts, Chinese miner relocations were a major reason behind sharp fluctuations in Bitcoin’s energy mix in 2020 and 2021. China’s crackdown on crypto in 2021 and the associated miner migration resulted in a major drop in the share of hydroelectric power in the BTC energy mix. As previously reported, Chinese authorities shut down a number of crypto mining farms powered by hydroelectricity in 2021.

“The Chinese government's ban on cryptocurrency mining and the resulting shift in Bitcoin mining activity to other countries negatively impacted Bitcoin's environmental footprint,” the study suggested.

The analysts also emphasized that the BTC electricity mix hugely varies depending on the region. Countries like Kazakhstan still rely heavily on fossil fuels, while in countries like Sweden, the share of sustainable energy sources in electricity generation is about 98%.

The surge of nuclear and gas energy in Bitcoin's electricity mix allegedly reflects the “shift of mining power towards the United States,” the analysts stated. According to the U.S. Energy Information Administration, most of the nation’s electricity was generated by natural gas, which accounted for more than 38% of the country’s total electricity production. Coal and nuclear energy accounted for 22% and 19%, respectively.

Among other insights related to the latest CBECI update, the study also found that greenhouse gas (GHG) emissions associated with BTC mining accounted for 48 million tons of carbon dioxide equivalent (MTCO2e) as of Sept. 21, 2022. That is 14% lower than the estimated GHG emissions in 2021. According to the study’s estimates, the current GHG emissions levels related to Bitcoin represent roughly 0.1% of global GHG emissions.

Combining all the previously mentioned findings, the index estimates that by mid-September, about 199.6 MtCO2e can be attributed to the Bitcoin network since its inception. The analysts stressed that about 92% of all emissions have occurred since 2018.

As previously reported, the CCAF has been working on CBECI as part of its multi-year research initiative known as the Cambridge Digital Assets Programme (CDAP). The CDAP's institutional collaborators include finance institutions like British International Investment, the Dubai International Finance Centre, Accenture, EY, Fidelity, Mastercard, Visa and others.

The new CDAP findings noticeably differ from data by the Bitcoin Mining Council (BMC), which in July estimated the share of sustainable sources in Bitcoin's electricity mix at nearly 60%.

“It doesn’t include nuclear or fossil fuels so from that you can imply that around 30-40% of the industry is powered by fossil fuels,” Bitfarms chief mining officer Ben Gagnon told Cointelegraph in August.

According to CBECI project lead Alexander Neumueller, the CDAP’s approach is different from the Bitcoin Mining Council when it comes to estimating Bitcoin’s electricity mix.

“We use information from our mining map to see where Bitcoin miners are located, and then examine the country, state, or province's electricity mix. As I understand it, the Bitcoin Mining Council asks its members to self-report this data in a survey,” Neumueller stated. He still mentioned that there are still a few nuances related to lack of data in the study.

Hydro plant from 1897 earns 3X as much mining BTC as selling power to the grid

An historic renewable energy facility in New York has tripled its profits by mining Bitcoin.

New York’s Mechanicville hydroelectric plant — one of the oldest hydropower generation facilities in the United States — is now host to Bitcoin mining.

The plant is owned by Albany Engineering Corp (AEC), which was asked to restore it by the National Grid in 1986. Jim Besha Sr., AEC’s chief executive, notes that cryptocurrency mining offers triple the profit margins available from selling electricity back to the grid:

“We think this is the oldest renewable energy facility in the world that’s still running. We can actually make more money with Bitcoin than selling the electricity to National Grid.”

Besha noted he is content to liquidate the BTC as it comes in, expressing skepticism regarding the crypto asset’s longer-term potential.

Despite the robust profit margins, Besha laments not selling his electricity to be used as power, but a decade of fighting with the National Grid has left him looking to alternative revenue streams.

When AEC was asked to restore the plant, a contract was signed with the National Grid guaranteeing it would purchase power from Besha for 40 years at a discounted rate. However, after AEC received licensing to operate independently in 1993, Besha claims the National Grid reneged on their deal, leading to a protracted legal battle.

After the facility incurred substantial damages from a flood, and later a generator catching fire, the National Grid agreed to give up the plant, pay for repairs, and purchase electricity from AEC at market value in 2003. Despite National Grid giving up its price discount, the profits from Bitcoin mining still dwarf what AEC can make by selling electricity.

AEC is not the first firm to repurpose a landmark of modern industry to generate cryptocurrency.

In 2018, Bitriver launched a data center in what used to be the world’s largest aluminum smelter in Siberia, which had been constructed by the USSR in the 1960s. The facility, which is now used to mine Bitcoin, is also situated near a major hydropower plant.

That same year, Coinmint announced it had signed a ten-year lease on a 1,300-acre plot of land in upstate New York that had once been used for aluminum smelting to host BTC mining hardware.
