Hybrids do not get plugged in. Most of the electrical energy they use comes from regenerative braking... the energy that is otherwise lost as heat. So, they "recycle" energy.
And even if they could be plugged in, and that energy comes from power plants that pollute, but so would the energy that is required to refine additional petroleum (besides transportation and delivery at the gas stations).

Thanks robertsmx for the reply! Your right, I had not realized that the latest cars don't plug in. My previous research on the web I had not found a good " how it works" that described this. It seems to be very simpily that the hybrids are small engines and elec motors that work together to supply enough power to accelerate and and then the small engine has enough power for the crusing. they also have the motor to recharge the Batts. When braking. Gosh I was getting 50 MPG in the sixtys on my 600CC Fiat and we used the generating feature on our slot cars for braking?

As has been stated in other posts, hybrids don't plug into the electric grid to get recharged. Even if they did, here in Southern California the electricity generators are either natural-gas fired, nuclear, or hydroelectric. Exhaust emissions from these sources of electricity as compared to exhaust emissions of the current crop of hybrids would seem to be even.
Now, where electricity generators are fuel-oil fired or even coal fired, it would be obvious to anybody that the comparison of exhaust emissions between such powerplants and the current crop of hybrids is a win for the hybrids.

"Even if they did, here in Southern California the electricity generators are either natural-gas fired, nuclear, or hydroelectric."
I suppose that coal-fired plant in the Mojave desert is generating electricity for some other state... nope, actually for Cal-Edison. There is a controversy on right now as to if it will stay open...

As I pointed out earlier, a plug-in vehicle will indeed draw energy from an electric power plant. But so will production and delivery of additional gallons of petroleum that a non-hybrid would need.
#12 of 13 hyrids are cleanest vehicles except pure electric

It has been studied and hybrid make less emissions than any vehicle except pure electric s. The electric comes from power plants that are regulated and have scrubbers on them to meet certain standards. 50% of US power comes from coal fired power, 17% from scary nuclear.
As was noted in another response hybrids make most of their power from coasting and regen braking, power lost on regular vehicles.
Hybrids are very clean. Most are also smaller and lighter and more aerodynamic like the Prius at .25 CD.

"As was noted in another response hybrids make most of their power from coasting and regen braking, power lost on regular vehicles."
Unfortunately not true. Hybrids simply recapture energy that was first expended (in one form or another) by the ICE. Either the battery was originally charged by the ICE, or the ICE contributed to the speed being used to be converted to regenerative braking. And of course the ICE created the speed used for "coasting".
No one has yet created the engine that will "make" power, a.k.a. "perpetual motion machine".
