There is a good, short article posted on-line recently in the Christian Science Monitor entitled, “Arizona’s Solar Aspirations In Peril”. The article suggests that large-scale solar power plants are still far from being competitive with conventional fossil-fired plants, even in a place that sees 325 days of sunshine per year. According to the article, expiration of the federal Investment Tax Credit in 2008 is going to sink a 1 billion dollar solar project slated to elevate Arizona’s prominence as renewable energy hub.
