Bitcoin mining, often criticized for its energy consumption, is becoming a surprising ally in Europe’s energy transition. As the continent faces an energy crisis and adopts stricter regulations, bitcoin mining is proving its flexibility and utility. By helping to stabilize grids, utilizing surplus energy, and integrating with renewable sources, this technology is becoming an unexpected and vital part of the energy conversation.

Germany, renowned for its engineering, is leading the charge with projects that blend bitcoin mining with sustainable practices, offering a glimpse into its transformative potential.

The European Energy Crisis

The European energy crisis, worsened by geopolitical tensions and rising energy costs, has pushed the continent to rethink its approach to energy consumption. Renewable energy sources like wind and solar now account for 59.7% of Germany’s public electricity generation. However, the intermittent nature of renewables presents challenges for grid stability.

The European Bitcoin Energy Association, founded in 2023, is exploring bitcoin mining as a unique solution to the challenges facing the energy infrastructure of the EU. Rachel Geyer, Chair of EBEA, explains, “Bitcoin miners can switch off when electricity prices surge and switch on when prices drop, making it an ideal partner for stabilizing grids.” Unlike data centers for companies like Amazon or Facebook, bitcoin miners are highly flexible, enabling them to act as a responsive energy consumer. This adaptability complements renewable energy generation and eases pressure on overburdened grids.

Beyond Germany, EBEA is collaborating with other European mining companies who are integrating bitcoin mining into national grid infrastructure. Austria, known for its use of hydroelectric power, offers an ideal environment for leveraging surplus renewable energy, and a pilot project to use bitcoin mining to help with grid stability is underway between the Austrian Power Grid and 21Energy. These efforts aim to harness this clean energy while addressing grid stability challenges. “EBEA is collecting proof-of-concept projects to demonstrate how bitcoin mining can help with the build out of renewables and aid grid stability,” Geyer notes.

Law and Subsidies

A new law in Germany is set to impact bitcoin mining. By encouraging the use of surplus energy, this legislation could position bitcoin mining as a key player in addressing overproduction and curtailment issues. “We shouldn’t be curtailing energy production—we should be using it,” says Geyer. Bitcoin mining’s modularity allows it to thrive in locations where excess energy would otherwise go to waste.”

While bitcoin mining holds promise, government subsidies for traditional renewable projects can distort the market. “Subsidies often create solutions that aren’t viable long-term once the funding dries up,” Geyer cautions. Bitcoin mining offers a market-driven approach to energy use, encouraging efficient and sustainable practices without reliance on subsidies.

German Engineering at the Forefront

Germany’s reputation for engineering excellence is evident in its approach to bitcoin mining. Companies like Terahash are at the cutting edge of this technology, developing advanced solutions. “The solutions we see today didn’t exist two years ago, which highlights the rapid evolution of bitcoin mining technology,” said Matthias Fendt, Head of Operations and Sales at Terahash.

By engaging with industry leaders, including giants like Siemens, Terahash brings these solutions to life, further bridging the gap between bitcoin mining and Germany’s industrial expertise. Their projects extend beyond Germany, demonstrating the potential for bitcoin mining to integrate with sustainable energy practices across Europe.

Terahash’s “Genesis” project in Finland shows how well the integration works. This facility operates entirely on renewable energy, utilizing high-temperature miners to generate heat at 70°C. The produced heat is fed into the local district heating network, helping to provide year-round energy for a Finnish town of 12,000 residents—supplying domestic hot water in the summer and heating homes in the winter.

This makes bitcoin mining a major source of heat for the town, showing how sustainable and ecologically responsible mining can be implemented in Europe.

A German Kärcher car wash equipped with solar panels demonstrates how bitcoin miners can be integrated into everyday operations. Solar energy powers two bitcoin miners, which generate heat to de-ice floors in winter and warm water for cleaning, providing a fully integrated, energy-efficient solution. “These small-scale projects are driving innovation and showing the versatility of bitcoin mining,” notes Geyer.

The Vision

Bitcoin mining is increasingly being explored as a part of Europe’s changing energy infrastructure. Projects in Germany and other regions illustrate how integrating renewable energy goals and practical applications can contribute to energy solutions.

“We are involved in several projects which incorporate bitcoin mining. In one case, we’re collaborating with an industrial park to enhance its appeal to potential businesses. By integrating solar PV, battery storage, and bitcoin miners, we can achieve multiple use cases: grid stability, predictable energy costs for companies, and heat supply for community spaces like a middle school, event hall, and swimming pool—while retaining the existing central heating as a backup.

The cashback from bitcoin mining helps reduce costs and cover maintenance. Fully integrated multi-use-case sector coupling projects like these create real value for people and businesses while simultaneously strengthening the decentralization and security of the bitcoin network. In this way, we promote sustainable prosperity and sovereignty.” explains Fendt from Terahash.

“Bitcoin mining isn’t just about creating digital currency—it’s about solving real-world problems,” Geyer concludes. As Germany and Europe embrace these possibilities, the synergy between bitcoin and sustainable energy could pave the way for a brighter, more efficient future.
