Commenting on "Deep and meaningful"

Using the heat energy from high temperature rocks to generate power is no difference from burning coal, releasing the stored energy. The cool water is heated to form steam, which either enters the atmosphere or back to the ocean, and subsequently raising the global temperature. Moisture is in fact considered as a greenhouse gas, and whatever benefits gained from geothermal energy will be negated.
Like coal or oil, the energy from this high temperature rocks is not renewable. One possible way to have completely clean, cheap and renewal energy is to build mobile / rotatable structures out in the sea (not dissimilar to oil platforms). These structures are built with a combination of wind turbines, solar energy collection dishes and wave turbines.
