Whereas Europe races to section out fossil fuels and electrify every little thing from automobiles to heating programs, it’s turning a blind eye to a dependable and confirmed supply of unpolluted power mendacity proper beneath our ft.
Geothermal power gives precisely what the continent wants most: clear, native, always-on energy. But, it solely accounted for 0.2% of energy technology on the continent in 2024. One thing wants to alter.
The current blackout in Spain, triggered by a failure within the high-voltage grid, serves as a warning shot. Whereas photo voltaic and wind are very important pillars of decarbonisation, they’re variable by nature. With out regular, around-the-clock sources of electrical energy, Europe dangers swapping one type of power insecurity for one more.
A a lot greater wake-up name got here in 2022 when Russia launched a full-scale invasion of Ukraine. For years, European governments had constructed an power system depending on imports of pure fuel. When that stack of playing cards shattered, it triggered an power disaster that uncovered the weak underbelly of Europe’s energy system.

Hear her story and the way she developed a startup to stop scams and fraud utilizing know-how on June 19.
The reply to those issues lies, partially, a number of kilometres underground. In keeping with the Worldwide Vitality Company, geothermal power has the potential to energy the planet 150 occasions over. But it surely’s not nearly electrical energy — geothermal can even ship clear, dependable warmth. That makes it particularly useful in Europe, the place hundreds of thousands of properties already depend on radiators and district heating programs, lots of them nonetheless powered by pure fuel.
Geothermal crops additionally include a smaller footprint. They require far much less land than an equal photo voltaic farm or wind park. What’s extra, the supplies and infrastructure wanted to construct them — like drilling rigs and generators — might be largely sourced domestically. That’s a pointy distinction to photo voltaic panels and batteries, most of that are imported from China.
Geothermal power is just not theoretical. It doesn’t require scientific breakthroughs. We’ve been drilling wells and extracting power from the Earth for hundreds of years. The know-how exists, and so does the workforce.
Many years of oil and fuel exploration have constructed a deep bench of geologists, drillers, reservoir engineers, and mission managers. As an alternative of letting this experience fade, we will redeploy it to construct geothermal crops. The infrastructure, resembling drilling rigs, may also be repurposed for a cleaner trigger. Geothermal could possibly be the final word redemption arc for oil and fuel.
Positive, drilling deep isn’t low-cost — but. However a new crop of startups is rewriting the playbook. Armed with every little thing from plasma pulse drills to large radiators, these firms may lastly crack the fee barrier — and make geothermal accessible just about anyplace. Simply as SpaceX disrupted a sclerotic rocket trade with its low-cost launches, these startups are poised to succeed the place the geothermal trade has failed.
All that’s lacking is funding. Whereas billions are being funnelled into high-risk applied sciences like fusion or nuclear fission reactors, funding for geothermal tech is minuscule compared, particularly in Europe. But, in contrast to these applied sciences, geothermal is prepared proper now.
If Europe needs to attain local weather neutrality and power sovereignty, it should cease ignoring geothermal. We’d like daring funding, regulatory reform, and a transparent sign to trade: don’t let geothermal grow to be a forgotten renewable.
Grid failures, missed local weather targets, deeper power dependence — these are the dangers Europe faces. It’s time to start out drilling, earlier than it’s too late.
