[quote=spdrun]Even if utility costs were 100% higher, you won’t be using twice as much electricity in SD as opposed to Phoenix. First off, you’ll have a smaller home. Secondly, A/C cost is the 1000-lb gorilla in the room in Phoenix, and is much lower in most parts of SD Co. Third, doesn’t the global warming solutions law come with some nice subsidies for home solar systems?[/quote]
A/C may not cost as much as you think in Phoenix. My highest electric bill in a 2200 sq ft home in Phoenix was less than $100 last summer, the A/C is set at 78 and it’s on pretty much non-stop from June through Sept. In my 3600 sq ft home in SD, my electric was never less than $200 and more than doubled during the winter. I didn’t have A/C, but I’m guessing A/C would cost a lot more than heat.
