if we agree with the Solar System origination from a dissection of the (original-bigger)
Sun, even the geothermic is "solar" energy. Well, 'wind' definitely is, hydro indirectly.
We need lots more of usable energy for humankind's survival - to save energy <G>
and I am an advocate of the geothermal, transforming the (oil-wells in
exhaustion) into
steam-production by lowering the level into 'hot' depth and pumping down desalinated
water in a double conduit where the overheated steam can come up into turbines (all
figured within today's circumstances). It will save profits to the oil magnets and is a
pretty constant - hard-to-reduce source. Sea-based hydro is another good option.
Just let's forget about coal, oil, nuke: coal and oil should be used as a staple for
chemicals (only), nuke should NOT be used as fission-process.
I think liquid salt thorium based fission reactors are a good energy source. They can be
used to burn up plutonium and uranium from aging weapons. The radioactive material left
to dispose of is orders of magnitude smaller and it's hard to divert material to weapons.
And since solar and wind are variable we either need a way to store the energy (dams?) or
to supplement those sources.
It is suicidal.
Any additional thoughts?

I have one objection to present terrestrial usage of solar energy: the (NOW!)
existing
technical level requires costly maintenance. I consider it temporary.
Most PV installers guarantee 80% rated power or more for 20yrs. A lot of conventional
power plants don't last more than 20yrs. In the long run, everything is temporary.

it's not an either-or choice. And that the Sun shines all the time, just
not on
your spot? And that energy can be stored? I assume you're switching to
nuclear.
