Solar and wind are excellent, but it's the energy under our feet that has the world talking.
Most experts agree that we'll need more than one form of energy to sustain our booming population in the decades to come. Coal and nuclear energy are on their way out, and as promising as solar, hydro and wind energy are, they suffer from intermittent availability.
One alternative energy possibility that's just now getting worldwide recognition is geothermal: heat from the Earth's core that creates steam which can then be converted into electricity through traditional processes.
Geothermal energy has the potential to provide more than enough juice to power the world, and it's abundant in many countries around the world, including the United States.
Continue reading to learn more about geothermal energy, and why it can be considered a viable alternative for creating energy.
