The question you should be asking is "how do I prepare for the future?" The sudden surge in oil prices, and the effect that this has on other things we buy, should be a sign that we should act now, before it's too late. George W has a horrible environmental record, but has installed all sorts of alternative energy systems at his ranch. That should tell you something.

IMHO You don't need a $35000.00 system. You need enough PV to keep you comfortable and safe in your home, and to help you prepare and preserve food. You might also think about growing and raising your own food. Or, you could simply do what many people do; hope that things never get that bad, or hope to be rescued if they do. It's your choice.
