Since I have never seen even a scrap of reasonable prognostication about energy technology on the Internet, I would like to put down a brief synopsis of the future as I see it.

Fission is going to die a well-deserved death. The reasons are simple:
1. It is too expensive and not competitive with other methods.
2. There is not enough high-grade uranium ore to provide sufficient fuel. The use of low-grade ore will require either (a) as much, or more mining than coal for the equivalent amount of energy or (b) the deployment of a fast breeder reactor design worldwide. The latter is even MORE expensive than light water reactors and also requires highly enriched fuel that can be used for bombs.

Fusion power is dead-on-arrival. It will never be practical because if will be even more expensive than fission. If we have learned anything from the past FORTY years of fusion research, it is that fusion is complicated, difficult, and therefore will be prohibitively expensive.

Now that these hopeless energy technologies have be put to a well-deserved rest, what WILL work?

There are EXACTLY FOUR energy sources that hold hope for the long-term future:

1. Harnessing of the ocean thermal gradient for production of electricity and energy-rich chemicals such as liquid fuels.
2. Conversion of biomass into liquid and gaseous fuels.
3. Wind turbines.
4. Photovoltaic arrays.

In addition, a few energy transport and storage technologies hold promise for moving energy through space and time.

1. Hydrogen.
2. High efficiency rechargeable batteries such as metal hydride and lithium.
3. DC electric power grids.
4. Flywheel storage.

Having studied this for some three decades, I honestly haven't found anything other than those mentioned above. If I have left anything out, please let me know.
