I just read an article the G-Biz news letter which hits on this topic. It seems the entire solar industry is highly dependent on worldwide Government subsidies. Now that these subsidies are drying up in several European countries, some manufacturers have begun to close their doors and the solar industry itself may continue to shrink substantially over the next few years.
I can’t help thinking that the something is in the air for the ethanol producers when and if corn subsidies begin to go away due to Uncle Sam’s teat running dry.
