Climate Policy

Let me see...

1. The sun is responsible for solar (of coarse), wind, biomass and fossil fuels (ancient plants). Wind and hydro are ways to capture solar power that evaporates water changing the density of the air (affected by gravity). Shallow geothermal (not the hot springs) is due to solar radiative heating of the ground.<>
   
2. The moon (and to a lesser extent the sun) is responsible for tidal energy, which is pretty predictable.<>
   
3. Deep geothermal is virtually limitless because it is generated by the gravitational action of the sun and moon on the earth as well as radioactive decay.<>
   
4. Other chemical reactions releasing energy <>
   
5. And, then, there is nuclear power, both fission and fusion.<>
   [st]And, who knows, maybe there is something else we haven't discovered yet.

Does this list of alternatives proof that geothermal and wind energy are sustainable?
