Not really surprising. The Volt makes you think about kwh as a resource. Once you do that, you start seeing all the ways resources can be conserved. We were well down this path before we got the Volt. I have written a bunch of articles on such items. (ie, http://gm-volt.com/2013/04/16/new-le...evse-possible/) We now get paid by the utility for the annual excess of kwh that our solar produces. Unfortunately, they pay you at wholesale rates, so I now have very little incentive to see where any more kwh can be saved- at either home or office.
