Solar energy and photovoltaics are not necessarily synonymous
A more efficient (and less polluting to manufacture) technology is sun tracking point source reflectors (they use mirrors) that either drive Stirling engines or concentrate sunlight on smaller high output photovoltaics (rather then the big PV arrays). We should be covering our southern deserts with them. (San Diego is one of the few utilities to have one of these plants built for them.) If you're in the sun belt, kick your local utility in the butt, and ask them when they're going to start building them.
