My post wasn't about taxpayer impact. It was about the economics of purchasing the Volt for the individual buyer. Note that GM's not the only car maker benefiting from tax credits on fuel-sipping vehicles that run fully or partially on battery power. Every car maker that manufactures one does - including Toyota, Nissan and Ford.
I still haven’t seen any numbers added in for wiring residences, nor the electric bill... Especially with the Administration gunning for the coal industry and hydraulic fracturing, the process which makes natural gas as cheap as it is right now.
