As the world continues to grapple with the challenges of climate change, renewable energy sources like geothermal power have become increasingly popular. We’re told that geothermal energy is a game-changer, a clean and sustainable way to generate electricity that’s free from the drawbacks of fossil fuels. But is that really true? The answer, it turns out, is more complicated than you might think.

For one thing, geothermal energy isn’t as green as you might assume. While it’s true that geothermal power plants don’t burn fossil fuels and therefore don’t emit greenhouse gases during operation, the process of harnessing geothermal energy has its own set of environmental costs. For example, drilling for hot water and steam can cause earthquakes, just like traditional oil and gas drilling. And the chemicals used to stimulate and enhance geothermal production can contaminate nearby aquifers and harm local ecosystems.
But that’s not all. Geothermal energy also has a major flaw that’s often overlooked: it’s not very scalable. Most geothermal power plants are built near volcanic regions, which are relatively rare. And even where geothermal resources are abundant, the technology to extract them efficiently is still in its infancy. As a result, geothermal energy is currently only able to meet a tiny fraction of global energy demand – around 0.3% of global electricity production.

So why are we so enamored of geothermal energy, then? Part of the answer lies in the way that politicians and industry leaders have hyped it as a silver bullet solution to our energy woes. But there’s another factor at play: the influence of special interests. The geothermal industry is dominated by a handful of large corporations, which have a vested interest in promoting the technology as a panacea for our energy problems. And what better way to convince the public of its merits than by touting its environmental benefits?
Of course, that’s not to say that geothermal energy doesn’t have its uses. In certain regions, like Iceland and the Philippines, it’s a vital source of power that’s helping to reduce reliance on fossil fuels. And researchers are making progress on developing new technologies that could make geothermal energy more efficient and accessible.
But let’s not kid ourselves: geothermal energy is not the revolution in renewable energy that we’ve been led to believe it is. It’s a patchwork solution at best, with significant environmental and scalability limitations. As we look to the future, we need to be honest about the challenges and trade-offs of geothermal energy – and start exploring other, more promising alternatives to fossil fuels.
