I ran across and interesting article about an enormous source of energy just beneath (almost) our feet. It is projected to possess enough clean energy to fuel the planet for 170,000 years. This geothermal energy is much more accessable in certain geographic locations throughout the globe. The drilling technology to access this energy will still need to be developed but it technologically feasible. A lot of work needs to be done to bring this into fruition but it is a very positive sign for the future.
