For this homeowner, going solar was necessary "for both environmental and economic reasons – PV has become efficient enough to create more energy than it takes to manufacture it; it’s cleaner to use than most forms; and the tax incentives help to make the dollar payback time reasonable."  In order to save the environment they employ solar hot water as well as solar electricity and often choose to bike to save miles on driving- when they have to drive, they use their hybrid vehicle. "Solar power is the way to go in Southern Arizona.  We wish more people were putting it on their roofs."
