And yet nature all around us seems to thrive on solar power alone, with zero toxic waste byproduct.

I don't think pollution in production is a must, either. You don't have to dump your garbage in the river.

First off no, nature doesn't thrive off solar power alone. At the very least hydrothermal vents provide energy to most aquatic life past the thermocline.

I'd also like to point out that the sun produces more radioactivity then anything likely to be found on earth, and fusion as a whole accounts for all the heavy metals ever created in the universe. (just some food for thought).

I know about the hydrothermal vents, but I don't think nature needs them.

The sun example was discussed to death in another thread. Sorry, I think it is just a silly comparison.

Nature around us doesn't use eletricity either.

Of course it does. In any case, it uses power, the distinction is quite meaningless. Converting power can be done with a constant factor.
