Energy sources in the next 20 years

Glenn has presented evidence that oil & gas, while important, are not
going to be sufficient for the world's energy needs in a decade or two.

Other sources indicate that even if they were, environmental impacts --
global warming or whatever -- are such that alternative energy sources
are required anyway.


Coal (environmental problems)
Nuclear fission plants (radioactive wastes problems)
Nuclear fusion plants (uncertain technology + above)
Wind power (some help but not enough)
Solar cells (same as above, even at 80% efficiency)
Tidal power

The 12/03 issue of the Bulletin of Atomic Scientists, page 8, has some
info on this last one. Ten square miles of the Pacific Ocean is enough to
supply all of California's needs on an indefinite basis. 10 gigawatts of
potential energy around the UK alone. Glenn has reminded us of the energy
costs to build such facilities, but in the long run they look as if they
produce an energy surplus (unlike fuel from corn products). Apparently
Spain has a facility in operation at this time.

BAS being a reputable journal, that gives me some hope. Comments?
