What a feedback loop
This is a post at Bishop HIll that's so brief I've copied the whole.
The insanity of greeneryThis from a correspondent:
A German aristocrat of my acquaintance has figured out that the price he will be paid for the output of a solar panel is so high compared with the price he will pay for his input of normal electricity, that he is thinking of rigging up powerful arc lamps to shine on solar panels on his extensive roof.
While It's a little hard to believe that the price difference is large enough to make this worthwhile,. it' s certainly not impossible that the German government has set prices that way. If this person has very high efficiency photovoltaics (> 40%) and the price difference was at least 250%, it would break even. For example, if he's buying energy from the grid at 10¢ per kWh and selling the solar energy back to the grid at 25¢ per kWh, it would break even.
