Miners play a crucial role in the Bitcoin (BTC) ecosystem, and they’re constantly expanding into new areas. Not only that, but they’re also discovering innovative use cases for their powerful computers.
This expansion not only helps them create new revenue streams but also contributes to making the Bitcoin network even more robust. The greater the mining power, the higher the level of security it provides.
Primarily, miners confirm BTC transactions and secure the Bitcoin network, earning newly issued BTC and collecting transaction fees in the process. Their mining machines, specialized and powerful computers notorious for their energy consumption, are essential to the network's security. This high energy usage is what makes Bitcoin secure, as a possible attack on the network is now extremely complicated and improbable.
The significant electricity consumption of the Bitcoin network also positions miners as influential players in the power industry. Additionally, an advantage that Bitcoin miners leverage is that nearly all the power they consume is converted into heat. More details on these aspects are provided below.
1. Heating businesses and homes with Bitcoin miners
This is perhaps the least unexpected mining use case discussed in this article. The heat generated by these computers, known as ASICs (application-specific integrated circuits), is already finding practical applications. Various companies are harnessing this heat to warm their premises. For instance, a Dutch tulip-growing firm employs Bitcoin miners to heat its greenhouse, concurrently earning BTC in the process.
Similarly, a bathhouse in New York is utilizing Bitcoin miners to heat its pools.
Moreover, this technology extends to home heating. Several preassembled plug-and-play devices, such as Heatbit, Bit-Heater, products by 21Energy, and others, serve dual functions as home heaters (and, in some cases, air purifiers) and BTC miners. However, potential buyers should carefully calculate the costs and benefits of running such a heater, taking into account specific conditions and user needs.
2. Balancing power grids
Another advantage within the Bitcoin mining industry is the almost immediate on/off capability of its machines. This feature enables active participation in demand response programs, even endorsed by the US Energy Department, thereby assisting in the balancing of power grids. For instance, during periods of low electricity demand, miners can quickly utilize excess energy to power their machines. Conversely, when demand is high, they can promptly turn off their machines, redirecting more energy to meet the needs of more critical users.
A notable instance occurred in Texas this January (once again) when miner operators curtailed gigawatts of power to aid the local grid during a cold outbreak in the state. However, it's not about altruism; demand response programs are also highly profitable for miners, as they receive compensation for temporarily shutting down their machines. In some cases, the profit from these programs may even surpass that derived from regular mining operations.
3. Helping the renewable and alternative energy industry
A somewhat similar use case can be observed in the renewable energy sector, where projects often face challenges in achieving sustainability and rely on subsidies for operation. For instance, a local solar-powered electricity producer might encounter difficulties maintaining a project without a connection to a power grid.
Gridless, a Kenya-based company backed by Twitter (now X) founder Jack Dorsey, addresses this issue in Africa by supporting the financial viability of mini-grids through the integration of small-scale Bitcoin datacenters. The company elaborates on its website, stating, "Communities benefit with better grid stability, less expensive power, and more connections. We earn Bitcoin."
How Bitcoin mining can contribute to a renewable energy project
4. Reducing methane emissions
According to the United Nations Environment Programme, methane, a potent greenhouse gas, has an 80 times greater warming effect on the climate than carbon dioxide over a 20-year period. Notably, significant amounts of methane are released by oil, gas, coal mining operations, and landfills.
A solution to this critical issue has emerged with the involvement of Bitcoin miners, who effectively convert these gases into electricity to power their mining machines. In these instances, miners leverage another advantage of their industry – its ability to operate anywhere with an internet connection (and, of course, an energy source) without the need for expensive power grid infrastructure.
5. Enhancing access to drinkable water
Another emerging concept involves the potential of Bitcoin mining to contribute to the provision of drinkable water in regions facing severe water stress. This approach mirrors the way Bitcoin aids in making solar energy projects financially viable, as discussed earlier.
Cleantech investor Daniel Batten contends that miners could play a role in expediting the development of renewable-powered desalination and enhancing its efficiency.
“By accelerating the build-out of new solar energy capacity, Bitcoin mining can help UAE to transition to renewably-powered desalination, meaning that UAE can meet its water security goals without endangering its emission-reduction goals,” explains Batten.
An example of such an initiative could be the collaboration between Nasdaq-listed Bitcoin miner Marathon Digital Holdings and Abu Dhabi-based blockchain and digital asset company Zero Two. This joint venture is also addressing the desalination challenge:
Better image and sustainability
The aforementioned relatively new use cases for Bitcoin mining have not only increased the industry's revenue and fortified the Bitcoin network but have also had another significant effect.
Last year, they contributed to changing the prevailing narrative in mainstream media that Bitcoin mining is detrimental to the environment. Instead, the focus shifted towards acknowledging how Bitcoin mining can be beneficial. Even KPMG consultancy acknowledged last year that "Bitcoin appears to provide a number of benefits across an ESG [Environmental, Social, and Governance] framework."
In addressing concerns about the overall energy consumption of Bitcoin, there's positive news from Daniel Batten as well. According to the investor, "Bitcoin now uses 54.5% sustainable energy, the highest percentage among any global industry."
