- Hey, I can say "sustainable energy use", it's a pleasant enough noise,
- but has little meaning in this context. Sunlight draws on a finite
- supply of nuclear energy, just like any other energy source. The
- timescale is rather long, but then so are other nuclear energy options
- available to us such as fission and geothermal. The real choice lies in
- which method of tapping nuclear energy is most efficient given our current
- and projected technology. Right now we still have large supplies of
- stored and concentrated nuclear energy in the form of coal, oil, and gas.
- In the future we will have to decide whether current biomass inventories
- are sufficient, or whether we will have to approach nuclear energy more
- directly through fission, geothermal wells, or active mechanical solar
- collection via hydropower dams or windmills or solar cells or solar
- thermal plants. The amount of energy we require and the economics of
- tapping that energy will determine which technology we embrace most
- strongly.
