Allen,

<<Cost parity has not been achieved for solar energy, but it's very close. >>

This is my impression as well. I have yet to see, though, someone that takes all the costs with an energy source and pit them against each other. Like for solar, there probably is a cost in pollution from the initial manufacture of the components. But after the thing is built, as long as this plant isn't 100 miles away from the big city and you have hundreds of people driving to work and operate the plant, it shouldn't produce much pollution. For a coal plant, there would be the typical construction costs and pollution. But what about the continued work to get the coal out of the ground for a coal burning plant? What about the extra pollution that is caused by such a plant? What about the health care costs associated with the extra pollution from the plant? What about the environmental impact of all of this? Until all these things are taken into account, as well as other things on both sides of this debate that I have left out, I don't think we know what the true costs of our energy really is.

Wise use of solar is already MUCH better than ANY fossil fuel source. How? Used for heating. Simply targeting the best use of solar technology at space & water heating would be far more useful than all the biofuel nonsense, and would not have caused the economic and environmental issues. Unfortunately, the technology is not cool, so everyone is chasing PV instead. Too bad. I have no problem with PV either, but there is low hanging fruit that can be easily plucked.
