Well, and then overlook the fact that they're probably going to end up in a landfill somewhere. That's just it. The Prius is old enough now where there's probably plenty of them which have stopped working. What's happening to those big old batteries? And how much energy and resources does it take to produce them? And if you are a conservationist, how much pollution?

I don't know. I love the idea of getting off the grid, saving money and making things greener. I just don't think any of this does it yet. And it's certainly not worth doing on a national scale. Not yet.

You're right. You would have to want to do it for reasons of getting off the grid. I think you would have to look at the whole life cycle of the panels and batteries you're using before you could call yourself truly green.

Yeah, it got a little long. I wanted to correct what I'd said and supplement with the information I found.
