As the world grapples with the existential threat of climate change, it’s time to rethink our dependence on fossil fuels and turn to more sustainable sources of energy. But, surprisingly, geothermal energy has been quietly generating power for decades, and yet it remains woefully underutilized. In fact, it’s estimated that only about 13% of the world’s geothermal potential is being harnessed – a staggering figure considering the immense benefits this clean and reliable energy source has to offer.

So, what’s holding us back from embracing geothermal energy as a panacea for our climate woes? For one, there’s a common misconception that geothermal power is only suitable for areas with volcanic activity. While it’s true that volcanic regions do provide ideal conditions for geothermal energy production, the truth is that geothermal resources can be found in countless other places around the world, including regions with sedimentary basins and even urban areas.
Another myth that’s been debunked by geothermal experts is that the technology is too expensive or complex. In reality, the cost of geothermal energy has decreased dramatically over the years, making it competitive with fossil fuels in many cases. Moreover, the technology has become increasingly sophisticated, allowing for more efficient and reliable power generation.

But, perhaps the biggest obstacle to widespread adoption is the lack of awareness about the sheer scale of geothermal potential. A 2018 study by the International Energy Agency (IEA) estimated that geothermal energy could provide up to 40% of the world’s electricity by 2050, reducing greenhouse gas emissions by an astonishing 1.4 gigatons annually. To put that into perspective, that’s equivalent to removing the entire carbon footprint of the entire US energy sector.
So, what exactly makes geothermal energy so special? For starters, it’s a zero-carbon source of power that’s available 24/7, without the intermittency issues associated with solar and wind energy. It’s also a locally generated power source, reducing reliance on long-distance transmission lines and enhancing energy security. And, unlike solar panels, geothermal power plants can be designed to operate at capacity factors of 90% or higher, making them a more reliable and efficient source of energy.
Of course, there are still challenges to overcome, particularly when it comes to financing and permitting. However, governments and private investors are starting to take notice, with countries like Iceland, Indonesia, and Kenya leading the charge in geothermal energy development.
As we hurtle towards a climate tipping point, it’s time to rethink our reliance on fossil fuels and turn to more sustainable sources of energy. Geothermal energy may not be the sexiest or most attention-grabbing form of renewable power, but its unique combination of reliability, efficiency, and zero-carbon credentials make it the unsung hero of the clean energy revolution. It’s time to unlock the full potential of geothermal energy and join the fight against climate change – before it’s too late.
