Do you seriously think that your local utility is going to have massive solar fields that are going to provide the kind of power demands they have or even a chunk of it? The only long-term option is for existing space to be used - power generation on the space used by the house it generates. Until that is affordable, I doubt it's going to make the impact we're hoping for.
Plus, come on. We all know how utility companies behave. They'll have to be dragged kicking and screaming into the type of investment necessary to roll these out, even if they're cheaper in the longer term.
Also, yeah, I wouldn't have had a clue what to google for the type of information you pulled up. Good for you. You get +1 google points for today, sport.
