Driving home in our 04 Lexus LX470 I realized just how much we've spent on gas...

There's this wonderful tool I found at Google that let's you search for that kind of information! "life expectancy PV panels" should give you the information you seek.

I think it's spelled googol.

Friendly mod pointer: discussions about solar, mix of electric generation sources, and policy matters all have threads in the Energy, Environment, and Policy forum.

Another $77 fill up today (87 octane). Come on Tesla, I need my S!

What? You dare put Regular gas in a Lexus? I thought I was on the "Livin' on the Edge" by using mid-grade (89 - 91) in my Lexus. Anyway, after 2 months, and 2,600 miles with my Model S, I'm averaging about $40 per month in electric fuel. I get a Tesla grin whenever I see Premium gasoline priced at $4.25 a gallon (or more).

Our 2004 LX470 has been fed nothing but the lowest grade for 9 years... 138,000 miles and has never been in the shop for anything but routine maintenance.
