I'm going to throw in some numbers here:
Based on Arkansas energy production, we use coal, natural gas, hydro, nuclear, and maybe some other stuff thrown in there, I don't remember. Anyways, there is a site that you can go to that will tell you the carbon emissions of an area. My electricity provider produces 1.1 lbs of carbon per kilowatt hour. (I think the average for the US is 1.5 lbs.) So let's do some math (sorry, I did this actually a couple of months ago, so it may not be perfect from my memory).
An electric Xebra with upgraded deep cycle glass matte lead-acid batteries will go 40 miles on about 7.3 kw hours. So lets round that to being 8 lbs. of CO2 released to drive 40 miles.
Okay, car number two uses gasoline and gets 20 mpg. I believe that adds up to about 39 lbs. of CO2 to go 40 miles.
-- I believe these numbers come from the EPA, so I assume they are correct.
That's 1/5 the CO2 emissions to go the same distance on electricity than gasoline. I'd say that is a significant improvement, so I think the government should be putting some of this investment/bond/bailout/loan/$$$$ into Electric Vehicle manufacturers. The money would be well spent in that arena, it is cost efficient and more eco-friendly than gas. It is more likely to be affordable to the average American. Plus, almost everyone has a place to plug in a car, so the infrastructure at least has a head start! (well maybe not if you count people living in huge cities like New York, but they can take public transportation :) )
I hear Obama talking about using hybrids in his government fleet, but what is wrong with BEVs? Several of our state and city fleets are buying up electric carts, trucks, buses, etc. and they are perfect. Most fleet vehicles drive short distances (landscaping carts, parking lot transports, security patrols, groundskeepers, and the list goes on...)
