Is it true that nuclear energy is the best alternative energy for the future ?

Did you know that a grandfather clock is indirectly solar powered?

Photosynthesis converts sunlight into energy which powers the grass.
The grass powers the cow.
The cow is converted into cheeseburgers.
The cheeseburgers power the guy who winds the grandfather clock.

Every form of energy that you can name is indirectly solar energy, with the exception of nuclear energy.

Wind - powered by the sun.
Hydroelectric - powered by the sun.
Coal, oil, natural gas - solar energy stored chemically.

Geothermal energy is not solar. It is derived from the decay of radioactive materials in the ground.

So, take the radioactive materials out of the ground, use them for a while, and put them back into the ground.

Done properly, nuclear energy will always be cleaner than burning oil or (shudder) coal.

The Earth is the most dense of all the planets due to its high concentration of radioactive materials.
