Sounds like you barely understand solar power grid systems and other options like the back up battery packs system for solar systems.
Gas engine is the horse and electric engine is the future. Doesn't mean you can't ride a horse today they are still around but it's stupid and unnecessary for daily commuting. I guess you never saw a Tesla solar power charging stations or Google head quarters with solar panels all over the campus.
My take is I can't wait for self driving electric cars and electric jeep with 600hp torque for all wheels and 1000 mile range per charge.
I have only 12x solar panels on my roof with 3000 watts with each panel making 250 watts each. I'm getting a positive gain in electricity for the whole year and is sent back to grid. Since I live in a sunny state i dont need as many panels to produce enough to run my house. If I add 8x panels I can run a Tesla free for the whole year too. That's electric and my system is warranty for 25 years.
That's find and dandy as long as you drive the Tesla for 8 years to offsett the associated emissions from the manufacturing process. At least according to a study I heard about recently.
The gentleman's point stands that a lot of people that purchase those units won't own the car for more than eight years, as the average in the U.S. is 80 months not 96. Just because the emissions are good doesn't mean it is immediately eco friendly.
Mother Earth likes it when we reuse and recycle, that's why everyone should buy a used TJ!
