Researchers have been working on using renewable energy sources such as solar and wind to power desalination plants, and reduce the need for traditional, fossil fuel-powered methods. Now, new research presents an untapped resource for powering desalination: geothermal energy.

"We're searching the world right now for better methods, low carbon methods, to create energy," says Thomas Missimer, of Florida Gulf Coast University. "We want electricity that's generated at base load—in other words, generated 24 hours a day without interruption. Geothermal is one of those types of energies."
