|Let’s start with
energy from the sun. It is the prime
driver of the carbon cycle. We’ve tried to tap it directly for generations.
are beautiful expressions of engineering art as are photoelectric cells for small loads.
emissions, even from the full manufacturing cycle, are quite small.
|Many tout these
forms of renewable energy as the ultimate solution.
the rotation of the earth and the vagaries of weather make both solar and
wind energy intermittent and unreliable.
these renewables for human needs thus requires expensive excess capacity,
energy storage systems and alternate generation.
those systems will compel us to use even more energy thanks to the
inefficiencies introduced through the multiple energy conversions needed.
