Another, still theoretical, type of geothermal energy production could also serve as a carbon sequestration system. Discovery News reported on the possibility of using carbon dioxide captured from fossil fuel energy plants in place of water in geothermal power plants.

Climate change isn't the only problem geothermal energy could help solve. Some of the world's least electrified regions, like Central America and Africa's Rift Valley, have tremendous geothermal potential.

"Combating climate change while simultaneously getting energy to the two billion people without access to it are among the central challenges of this generation. Geothermal is 100 percent indigenous, environmentally-friendly and a technology that has been under-utilized for too long," said Achim Steiner, UN Under-Secretary General and UNEP Executive Director in a press release.

"There are least 4,000MW of electricity ready for harvesting along the Rift. It is time to take this technology off the back burner in order to power livelihoods, fuel development and reduce dependence on polluting and unpredictable fossil fuels," Steiner said.

"From the place where human-kind took its first faltering steps is emerging one of the answers to its continued survival on this planet," he added.
