Because we have a geothermal system, our winter energy use exceeds our summer usage. We are doing several things to bring that down--I'm confident we can get within striking distance of our target. However--I have a new concern. And would appreciate any other general advice. I'm way out of my depth on this topic!

I know Tesla isn't the only company working on lithium battery technology, so am I ridiculous to worry? One of the company reps had this to say when I asked about it:

Musk and his team have a lot of ground to make up if they are going to surpass the established players in the market. The good news is that without a doubt those batteries are coming and as soon as we can get our hands on one, you will be ready."

This seems smart, no?  I've read other environmental concerns, such as panels being produced in a country that uses clean energy to produce them. Does anyone have suggestions about this?  The 2companies we have talked with are treating the panels very much like commodities & choosing based on price (& some quality standard), though I think will source pretty much whatever we want. Both of the companies we are talking to seem good, but neither has been in business a very long time, making things like warranties important to us.
