Most geothermal sources involve heated underground water or steam being pumped to the surface. This water and the chemicals dissolved in it can pose a significant hazard should they leak into the environment, causing land and groundwater contamination as well as the release of toxic gases such as hydrogen sulfide and radon into the atmosphere. The corrosive nature of the groundwater also means that the wells and pipes need to replaced periodically. In addition, only about 20% of the available heat energy is captured as electricity; the remaining 80% is simply radiated into the environment.
No energy source is going to be 100% cost-free, and geothermal still appears to be less costly from an environmental standpoint than most.

No. There are no hidden cost in Geothermal Energy because it did not incur in land degradation, high emissions, forest destruction, animal extinction or health impact on humans.

Geothermal energy provides low cost, reliable, environmentally friendly fuel; supplies thousands of quality jobs; boosts rural economies; increases tax bases; reduces foreign oil imports; stabilizes prices; and diversifies the fuel supply.
Unlike coal and natural gas, geothermal incurs no “hidden costs” such as land degradation, high air emissions, forced extinction and destruction of animals and plants, and health impacts to humans.

Power engineers consider it a mature technology — a demonstrated one — and most of the technology, though 20 years old, is available today off the shelf. Utilities show keen interest in it because it is steady, not intermittent like wind and solar. However, like those two energy sources, geothermal is renewable. It has high initial costs, roughly two-thirds coming from drilling. But, once built, it has no fuel costs.
Geothermal has been among those renewable energy technologies, which are currently commercially available and which the IPCC has recommended as a way to mitigate emissions from energy production. If geothermal is done correctly and respectfully — no development on sacred sites or in wilderness areas and national parks — we can bring hundreds of megawatts online.
