Addendum to "One Fewer"

In following the posts at the One Fewer website mentioned in the blog below, my feedback was responded to with this (as posted by one named 'Rog'):

Is it worth mentioning that the 150 MPG SUV achieved it’s impressive score by
creative accounting? In their sums they include 240 miles driven on battery
(charged by plug-in) and 60 miles driven hybrid, using 2 gallons of petrol,
giving, they say, 300 miles for each 2 gallons of petrol. No mention of the coal
that was burned to power the 240 miles!
This is not to say that a conversion
to hybrid might not improve the existing 13 MPG of that guzzler of yours, but
don’t hope for anything near to what AFS Trinity claim.

And, realizing that this was a valid argument, I felt compelled to follow up. After a bit of site searching for legitamate links, I followed up with this:

Yes, Rog, I do agree that we should consider the impact that coal-generated
electricity usage has on the overall picture. Roughly 50% of this nation’s
electricity does come from coal and so there are indirect environmental impacts
to using electricity to fuel our transportation sector.
That being said, let’s take innovation one step further and involve Nanosolar and their nearby San
Jose manufacturing facility (which is already shipping panels). Utilize their technology as charging stations
for the electric-hybrid Rover. Already, solar is looking to be cheaper than
coal, and obviously far more environmentally-friendly.
There is not going to be one silver bullet that will fix everything. To believe so would be ignorant.
Instead, there needs to be a comprehensive renewable-energy transistion strategy
put forth containing diverse efforts catered to each region’s needs and
opportunities. Showing that existing gas-guzzlers can be mass-retrofitted with
green technology and that the alternative energy that technology uses can be
produced economically, locally, and in a way that doesn’t harm the environment
would be one big step in the transition process.

It is worth noting that we need start thinking about this issue not in 'Silver Bullet' scenarios, but in comprehensive, strategic, diversified efforts spread across numerous sectors (i.e. transportation, electricity, fuel, etc.). I'll be sure to follow up on this soon...
