The Chevy volt is what is called a "plug in hybrid". This means it's propulsion and energy storage systems are a mix (hybrid) of internal combustion and electric technologies. Also, you can add stored electric energy from an external source.
A conventional hybrid has a battery that is charged from the internal combustion engine (which is also providing mechanical drive) and the energy that is taken from the car during breaking (called regenerative braking. This is a method of providing counter force that is electromotive rather than frictional to convert the kinetic energy of the car to stored electricity and/or heat.)
A plug in hybrid has a battery that can also be charged from an external source of electricity. Further, the Chevy volt's propulsion is solely from electric motor(s). When the charge in the battery gets low, an internal combustion engine starts and runs a generator to provide electricity to propel the vehicle and re-charge the battery with any extra power not used for propulsion.
I think you are right on in the suggestion that people seem to believe they get their electricity free of environmental impact with a plug in hybrid. (Acid rain anyone?)
However, if cleaner sources of electrical power are utilized (such as solar, nuclear, fuel cells, wind, hydroelectric, etc... ) it is conceivable that overall environmental impact can be reduced greatly from what we create today.
You will have a small hydrogen fuel cell to power your house in this lifetime! Yeah, you'll have to buy the hydrogen, but how nice it will be to be "off the grid"

edit: I think the Volt is projected to have up to a 40 mile range before the internal combustion engine runs, which means some commuters might never even spit out a single hydrocarbon while they use this car.
