If you want to talk about sustainability, this is this. CNet reports that GM is putting some serious money into Sunlogics that will purchase solar equipment for GM and dealerships to create renewable power charging stations.
In turn, Sunlogics will use that added fund to increase production. As a part of a broader deal, GM will purchase power generated by GM and Sunlogics facilities.
Right now, I'm loving this reinventing of GM with an eye towards efficiency and sustainability through renewable power.
