Why Solar Power is Permanently Inefficient | Somewhat Reasonable
The above was produced more than 30 years ago by Petr Beckmann, a professor of electrical engineering at the University of Colorado. The intervening decades have not altered the validity of what he wrote and depicted here because it is based on immutable physical and mathematical realities. Those realities are not altered by any amount of laws, subsidies, mandates requiring green energy usage, tax breaks, regulations, political promises, good intentions or democratic voting.
From the above illustration, you can readily grasp that solar power is extremely inefficient for automobile use, compared to the familiar fossil fuel (gasoline). Solar energy is similarly inefficient for other uses of fossil fuels.

Solar Energy Is Inefficient and Impractical

Fundamentally all the green technologies can't recover or collect enough energy efficiently enough (there are energy losses in the collection mechanism) and quickly enough (time is money after all) to be market viable and competitive with other energy sources. Once they do, and once they can, the market will beat a patch to their doors and quickly adopt the market competitive green technologies.
This leaves us with two viable choices: 1) Petroleum based - hopefully with continued improvement in efficiency and pollution reduction and 2) Nuclear, be it fission (nasty radioactive by products and fuel wastes to deal with) or possible Thorium reactors - but I don't think that even a lab experiment has been built and tested yet, so call that one only theoretical.
For the Green lobby, nether s acceptable, so what sort of market viable energy sources do they offer? Distort the market with larger and more government subsidies!
Well, that's not really a solution when I want to heat my home, or drive to work, or turn on a light bulb, now is it?
The greatest experiment with this is Germany. For 20 years they've been investing in wind and solar energy generation, and within a short time of the subsidies being cut off, all of that is being decommissioned because it doesn't make financial sense to continue.
We should learn from Germany's experience on this, and not repeat it. At least not until the fundamental physics issue betters itself to making economic sense anyway.
