How Irish farmers turn cow dung into digital gold (Bitcoin)

Tom Campbell, an Irish dairy farmer who runs a farm in County Armagh, is using excess energy from his farm to mine Bitcoin.

An Irish dairy farmer has found an unusual way to make use of the excess energy produced on his farm — by turning to Bitcoin (BTC) mining. Tom Campbell, who runs a farm in County Armagh, Northern Ireland, produces renewable energy using a method called anaerobic digestion. This involves breaking down biodegradable material to a point where it creates methane gas, which can be used to produce electricity.

Campbell primarily uses the electricity to power his farm, but when there is excess energy that cannot be exported to the grid, he uses it to mine Bitcoin. Mining involves using specialized computers to solve complex mathematical equations, with successful miners rewarded with BTC. Bitcoin mining requires a lot of energy, and Campbell's farm produces up to 700 kilowatts of electrical output, equivalent to powering nearly 12,000 households.

The Irish government has set a goal to decrease greenhouse gas emissions by 25% by 2030. However, the agricultural sector in Ireland is responsible for over 35% of these emissions, with cows being the primary source. With 7.3 million cows in the country, managing their waste in an eco-friendly manner is crucial. Anaerobic digestion is a promising solution, potentially generating enough electricity for every home in Ireland if 41% of farms adopted the technology. This could make a significant contribution to achieving the country's greenhouse gas emission targets.

Campbell's decision to mine Bitcoin may seem unusual, but it makes sense from an economic perspective. When grid demand is low, miners can use the excess clean energy. By doing this, Campbell can sell the excess electricity to the grid as renewable, green electricity while profiting from Bitcoin mining.

While some farmers have raised concerns that meeting greenhouse gas emission targets could drive them into bankruptcy, Campbell's approach shows that it is possible to find innovative solutions that benefit both the environment and the farmer's bottom line. With renewable energy sources such as anaerobic digestion becoming increasingly popular, more farmers could turn to Bitcoin mining in the future to make use of their excess energy.

Bitcoin miners as energy buyers, explained

Bitcoin miners as energy buyers utilize renewable energy sources and excess electricity offered by utility companies to fuel their mining operations.

Does the energy system benefit from Bitcoin mining?

Bitcoin mining can spur demand for electricity, which can help advance the development of renewable energy sources, but it also uses a lot of energy and raises carbon emissions.

On the positive side, electricity demand generated by Bitcoin mining can be utilized to promote the development of renewable energy sources and speed up the transition away from fossil fuels. This is due to the fact that Bitcoin miners frequently look for inexpensive electricity, and renewable energy sources, such as solar and wind power, can offer this at a reasonable rate. Thus, Bitcoin mining can be viewed as a strategy for encouraging the creation of renewable energy plants.

By using extra energy that would otherwise be wasted, Bitcoin mining can also help the energy system. For instance, miners might decide to set up operations next to hydroelectric dams, which frequently have additional energy available at particular times of the day. Miners can contribute to improved utilization of the already available energy resources by employing this extra energy for mining.

On the other hand, mining Bitcoin may have detrimental effects on the energy infrastructure. For instance, mining can be a substantial energy consumer because it calls for a lot of processing power, resulting in a hike in the demand for electricity, which would raise energy costs. Additionally, increasing carbon emissions, which can contribute to climate change, may result if miners primarily use fossil fuels to produce electricity.

How do renewable energy resources benefit Bitcoin mining in rural areas?

Renewable energy sources offer a more reliable power supply for Bitcoin mining operations since they are less prone to experiencing power disruptions. Additionally, using sustainable energy for Bitcoin mining can support job growth and economic expansion in rural areas.

In the context of Bitcoin, gridless computing, which refers to the usage of alternative computing resources such as edge devices, can encourage the use of renewable energy resources to mine BTC in Africa. That said, gridless computing offers an alternative to the centralized electrical grid, which is often unreliable or unavailable in many parts of the continent. This can enable miners to operate in remote or off-grid locations using locally generated renewable energy sources, such as solar or wind power.

The lack of electrical infrastructure in many rural parts of Africa makes it challenging to establish and run conventional mining operations. Gridless computing, on the other hand, enables miners to power their mining machinery with portable, decentralized renewable energy sources like solar or wind turbines. This enables miners to establish operations in remote locations and make use of the region’s abundant renewable energy resources.

Gridless computing can also promote the growth of community-based mining operations, which can assist nearby areas economically by generating jobs and sources of income. By offering education and training on sustainable energy methods, these community-based mining companies can also encourage the adoption of renewable energy sources.

How do Bitcoin miners act as energy buyers?

To power their mining operations, Bitcoin miners either purchase electricity from conventional and renewable energy sources or develop and run their own renewable energy facilities, turning them into energy consumers.

Miners typically purchase electricity from energy providers, such as utility companies or independent power producers, to mine BTC. They then use that electricity to power their mining equipment. This can include both traditional energy sources, such as coal or natural gas, as well as renewable energy sources, such as solar or wind energy.

Hydro-Quebec, a Canadian utility company that sells electricity to Bitcoin miners, is a real-world example of how Bitcoin miners act as energy buyers. In order to take advantage of the low electricity prices in the province, the firm has been actively courting Bitcoin miners to establish operations there and utilize excess hydroelectric power to mine BTC.

In some circumstances, miners might also sign long-term agreements with energy suppliers, which could provide them access to a more reliable and consistent source of electricity. Large-scale miners can benefit the most from this, as it enables them to plan and budget for their energy requirements in advance.

By establishing and running their own renewable energy facilities, such as solar or wind farms, Bitcoin miners can also take on the role of energy users and function as energy purchasers. By doing this, they support the switch to sustainable energy sources as well as securing energy for their mining activities.

For instance, a Bitcoin miner called Genesis Mining has established operations in Iceland and is running them using geothermal and hydroelectric energy. This allows the miner to benefit from Iceland’s plentiful renewable energy resources and lessen its environmental impact. Additionally, one of the largest Bitcoin mining facilities in the world, KnCMiner, is powered by a wind farm that the company developed on its own land in Sweden.

To make use of extra energy that would otherwise be wasted, miners may also choose to locate their mining operations next to existing renewable energy facilities, such as hydroelectric dams or geothermal plants. For instance, the Bitcoin miner Greenidge Generation in upstate New York, U.S. generates electricity for its mining operations using extra natural gas from a local power plant. The company also constructed a 7-megawatt solar farm to help meet its energy requirements.

Do Bitcoin miners use renewable energy resources to mine?

While a sizable fraction of Bitcoin mining currently uses non-renewable energy sources, there is a growing tendency among miners to power their operations with renewable energy sources. It is likely that more miners will use renewable energy as it becomes more affordable to power their operations.

As already noted, Bitcoin mining uses a lot of energy for miners to validate transactions and add them to the blockchain by using powerful computers to solve challenging mathematical puzzles. Initially, the majority of Bitcoin mining took place in China, which is also the biggest generator of coal-based electricity in the world. As a result, non-renewable energy sources accounted for a sizable amount of the energy utilized to mine BTC.

When comparing Bitcoin mining by nation, the United States ranks the highest, making it a legal activity after Bitcoin mining was outlawed in China. The use of renewable energy sources by miners, such as hydroelectricity, is an increasing trend, though. This is especially true in areas with a wealth of renewable energy sources, such as Quebec and Iceland.

Additionally, due to a fall in the price of renewable energy sources, mining companies are beginning to use them to power their operations. Moreover, in order to fuel their mining operations, several businesses are also investing in their own renewable energy initiatives, such as solar and wind farms.

Why does mining crypto use energy?

The energy consumption of cryptocurrency mining is a trade-off for the security and decentralization of blockchain networks. However, through the use of sustainable energy sources and effective mining algorithms, there are ongoing efforts to make the process more energy-efficient and sustainable.

Mining crypto uses energy because it is a process that requires computers to perform complex mathematical calculations in order to validate transactions and add new blocks to a blockchain. These calculations use a lot of computer resources, which results in high energy usage. The main sources of energy consumption are the CPUs and GPUs, as well as the cooling systems necessary to keep mining rigs cool. 

The first step in mining cryptocurrency is to confirm the transactions on the blockchain network using a consensus algorithm such as proof-of-work, which calls for miners to solve challenging mathematical puzzles. Miners use specialized software and hardware, such as ASICs, to perform these calculations at high speeds. The first miner to solve the puzzle adds the following block to the blockchain and receives a specific quantity of Bitcoin (BTC) in return.

In order to increase their odds of becoming the first to solve the puzzle, miners are motivated to employ as much computer power as they can. As more miners join the network and competition heats up, the need for energy rises, resulting in increased electricity usage. According to some estimates, the entire energy use of the Bitcoin network alone might be comparable to that of a small nation.

The energy consumption of cryptocurrency mining is a concern because it has an environmental impact. The majority of the power required for mining is generated from fossil fuels, which cause the release of greenhouse gases such as carbon dioxide. The cost of electricity for mining can be rather high in some areas, which makes it less economical for miners.

Climate tech VC argues Bitcoin’s ESG positives outweigh its negatives 31:1

The Bitcoin network has a 31:1 positive to negative ratio according to climate tech VC Daniel Batten.

A climate tech investor has painted a bright view of the Bitcoin (BTC) network, suggesting BTC’s environmental positives outweigh its negatives by a whopping 31:1 ratio.

On Jan. 12, self-proclaimed philanthropist and environmentalist Daniel Batten claimed in a Twitter thread that “Bitcoin is probably the most important ESG technology of our time.”

According to Batten, the 31:1 positive impact ratio was calculated by researching and interviewing grid engineers, climate scientists, BTC mining engineers, methane abatement experts, and solar and wind installers.

The findings discovered 21 ways Bitcoin could be an environmental positive and just five ways it could be an environmental negative.

Batten said that the findings were “uncannily similar” to those for the solar industry.

Many of the positives involved renewable energy grids and benefits from mining such as being the leading technology for responding to grid power demand from over and undersupply. Bitcoin mining farms can be switched on or off depending on power demand constraints.

Additionally, BTC mining can be a solution for geographic curtailment. Power curtailment is a deliberate reduction in the output below what could be produced to balance energy supply and demand, or due to transmission constraints.

There are also benefits in innovation and methane reduction, according to Batten’s findings.

BTC mining can be used to reduce vented landfill gas and flare gas emissions by using this otherwise wasted energy to power rigs.

The handful of negatives included network emission levels, e-waste production, and the opening up of previous fossil fuel sites. However, the environmental positives far outweighed these negatives, according to Batten who opined:

“Bitcoin mining’s rapid renewable adoption can inspire other industry sectors to follow.”

“We see Bitcoin mining can play a real part in global methane mitigation,” he concluded.

On Jan. 13, the SCMP opposed the notion that Bitcoin was good for the environment by reporting that BTC accounted for 86.3 million tons of carbon dioxide emissions in 2022.

However, it did acknowledge that Ethereum saw its CO2 emissions drop from 21.95 million tons in 2021 to 8,824 tons last year, according to the data from Forex Suggest. The Ethereum Merge and switch to proof-of-stake last year reduced network power consumption by 99.98%.

1.5M houses could be powered by the energy Texas miners returned

Bitcoin miners appeared to be the model consumers for the ancillary services in the state.

During the winter storm in Texas in December 2022, Bitcoin (BTC) mining operators returned up to 1,500 megawatts of energy to the distressed local grid. It became possible due to the flexibility of mining operations and the ancillary services, provided by the state authorities. 

In his commentary to Satoshi Action Fund, Texas Blockchain Council president Lee Bratcher stated that miners returned up to 1,500 megawatts to the Texas grid. This amount of energy would be enough to heat “over 1.5 million small homes or keep 300 large hospitals fully operational,” according to the calculations from the Bitcoin advocacy group.

While there’s no specification regarding the exact time period in which miners have accumulated such an amount of power, the global Bitcoin mining hashrate dropped by 30% on Dec. 24-25, 2022. Miners appeared to be the model participants of ancillary services in the state, which stimulate customers to reduce their consumption during peak demand in order to stabilize the grid.

The winter storm in North America was so severe that it shut down Binance's cloud mining products from Dec. 24-26. During the days leading up to Christmas, a "bomb cyclone" unleashed extreme temperatures across the United States, leaving millions without electricity and claiming dozens of lives.

Back in March 2022, the Electric Reliability Council of Texas (ERCOT) established an interim process to ensure that new large loads, such as Bitcoin miners, can be connected to the ERCOT grid. Software providers have also begun working with miners to ensure they have the tools needed to properly enable grid balancing.

With its 14% share in Bitcoin hashrate, Texas is among the top states for Bitcoin mining in the United States, along with New York (19.9%), Kentucky (18.7%) and Georgia (17.3%).

5 altcoin projects that made a real difference in 2022

2022 was tough on crypto prices, but ETH, LDO, MATIC, DAI and ATOM all made a positive impact on the industry.

Bitcoin (BTC), Ether (ETH) and the crypto market had a rough 2022 from a price perspective, but traders are hopeful that 2023 will include bullish developments that push crypto prices higher. 

Despite the market-wide downturn, a handful of altcoins continued to make a positive contribution to the crypto space and thanks to Ethereum, the term altcoin is no longer a derogatory term.

Let’s explore the top altcoins that made a difference in 2022.

Ethereum fundamentals shone in 2022

Ether’s price hit a yearly high at $3,835 on Jan. 2 and has struggled to regain footing amidst the bear market and other macro factors. The Ethereum network is the top project in 2022 not because of Ether’s price action, but for its fundamentals and for completing the long-awaited mainnet upgrade. The Ethereum merge was completed on Sept. 15, 2022 and while many feared the merge to proof-of-stake (PoS) could cause issues, the transition was flawless.

The main advantage of PoS is that it is much more energy-efficient than proof-of-work (PoW) because it does not require expensive and energy-intensive hardware to validate transactions. This reduces usage costs for the end user and makes it a more sustainable and scalable solution for Ethereum's long-term growth. The Merge also reduced the Ethereum network’s energy consumption by over 99.9%.

Some analysts are bullish on Ether post-Merge due to its emissions schedule becoming deflationary. Although daily active users have increased for the network, emissions have remained inflationary and Ether price is still down from yearly highs.

In 2023, investors are hopeful that increased transactions on the network creates higher demand for Ether and that this translates to a boost in the altcoin’s price.

Lido (LDO) brought Ethereum network staking to the masses

Lido’s makes it easy for users to participate in Ethereum PoS as validators by providing a simple interface for betting without having to reach the high threshold the network requires to stake.

Since launching, Lido has earned $158.8 million in fees from their staked Ether protocol. At the peak, Lido saw 823 daily active users on Sept. 17.

With the Ethereum network Shanghai hard fork scheduled for March 2023, Lido will have a busy Q1 and all the Ether staked in the platform will have the option of being withdrawn. Aztec Connect, the creator of Lido protocol also recently secured a $100 million fundraising round to build an encrypted blockchain.

Polygon partnerships show long-term resiliency

Mass adoption requires traditional companies and brands to get involved in crypto. Polygon (MATIC) has a major focus on partnerships and some of the relationships developed in 2022 include Warner Music, JP Morgan, Instagram and Warren Buffett’s Neobank.

These partners use Polygon in various ways, including integrating the Polygon network into their infrastructure and using Polygon to offer distributed ledger technology (DLT) for their products and services.

Notable companies, including Cointelegraph, also chose to launch NFTs on Polygon. In addition to Cointelegraph, former President Donald Trump, Reddit, DJ Deadmau5 and Nike all launched NFT collections on Polygon.

Some traders expect a 200% upside swing from MATIC due to on-chain metrics showing traction and bevy of future partnerships. Despite all of Polygon’s growth, the Ethereum network still intakes more fees.

Polygon’s focus on Web3’s core principles combined with their partnerships, earned them a spot as a top altcoin project in 2022 .

MakerDAO’s DAI proves resilient

In a year that saw algorithmic stablecoins de-peg and perish, Dai (DAI) has shown resilience. Unlike centralized stablecoins, DAI is a decentralized stablecoin that provides transparency, censorship resistance, and the ability to operate outside traditional financial systems.

While DAI is not new to the crypto space, the decision to increase exposure in low-risk assets such as treasuries and bonds earns them a spot as a top altcoin. According to an analysis from Sebastien Derivaux, a crypto scholar, this decision generated 75% of all DAI revenues (600 million.)

Cosmos upgrades attract institutional investors’ attention

In 2022, Cosmos (ATOM) focused on solving the interoperability and communication challenges that exist between different blockchains. On Jan. 1, Cosmos had 74 active developers and this figure more than doubled, reaching a peak of 154 on Nov. 30.

In a year plagued with cross-chain casualties, Cosmos’ inter-blockchain communications protocol (IBC) has so far seemingly weathered the storm. The success caught the eye of Delphi Digital’s research arm and fund managers at VanEck.

Overall, Cosmos has the potential to be an important infrastructure layer for the crypto ecosystem, helping to facilitate the exchange of value and information between different blockchain networks and enabling a more interoperable future.

While 2022 is a year most crypto investors would like to forget, positive factors in mass adoption arose. The altcoins with a focus on building will continue to propel crypto’s future in 2023 and beyond.
