is the harvesting and conversion of ambient solar energy as humankind's principle means of electrical energy production merely a pipe-dream of radical environmentalists and left-leaning ideologues? probably
Don't know. Dieoff has a point, but geologists also predicted in the late 60's that "...taking into account all known oil reserves, both attainable and unattainable...we will run out of fossil fuel by the mid 80's..."
Course we didn't 'cause human ingenuity (and desperation) found both a way to increase gas mileage (as one example) by almost 10 times...while at the same time finding ways to harvest the "impossible" oil reserves.
As for hydrogen, possibly, however when taking into consideration the ENTIRE spectrum of the hydrogen process (from mining, to refining, to transport, to consumption) it is both less efficient and less environmentally clean than oil. Although, if the process could gain enough popularity to allow it to become cost effective and cleaner...it could be the front-runner.
I don't have much hope for solar energy, as it seems to have begun a decline before it even got started.
Wind energy has some great possibilities, although many have speculated that building enough wind generators (even offshore) to provide the needed resources could potentially change weather patterns.
I know it would make me a member of the evil empire, but I put my money on Nuclear. Although it has been low profile, we currently already have a strong dependence on the existing nuclear reactors and, as far as safety, in the broader scope, it has one of the highest safety records of ANY power source.
If we could ever satisfactorily learn to contain/reuse/destroy the waste, it would become the immediate winner.
