I have complained before about the foolishness of encouraging residential photovoltaic installations. Recent posts by Yglesias and Drum about feed-in tariffs which obligate utilities to buy (at exorbitant rates) power produced by small scale photovoltaic generation have provoked me into revisiting the subject. According to Drum:
... And yes, it's a very good idea that makes small-scale solar installations economically worthwhile.
Actually it's a very bad idea as the highly subsidized small scale photovoltaic installations are only economically worthwhile for the owners. They are economically wasteful for society as a whole because they are highly uncompetitive in cost with other means of generating electricity.
It is ironic that Yglesias and Drum who once claimed to be members of the reality based community (in contrast to the delusional Bush administration) now give uncritical backing to liberal programs that are equally detached from reality. It appears Republicans and Democrats just live in different fantasy worlds.
