Last week in Phoenix, I watched the very conservative governor of Arizona, Jan Brewer, deliver a brief keynote speech to open the second day of the CleanTech Future conference put on by CleanTech Connections and the Arizona Commerce Authority. Nineteen floors above the impressive solar PV arrays at Arizona State University's downtown campus across the street, Brewer extolled the virtues of solar and other clean energy as a business boon for her state.
