I always hear for either the pushing of wind energy and solar energy or the defending of oil and coal energy. To me it seems like geothermal, wave and tidal energies would be the best. It's not always windy, it's not always sunny, the other resources listed are finite. The earth's core will always be hot, there will always be ocean currents and waves. Am I as clueless as I sound? Or am I on the right track?
