How many cars would have to be replaced with hybrid vehicles to really put a dent in CO2 emissions?

    Merely replacing regular cars with hybrids is not going to do anything to carbon dioxide emissions, even if you replace them all at once. Well, ignoring the reduction due to more efficient engines in newer cars than the old one we’ll replace. And, adding the increase due to the CO2 emissions created during the production and shipment of the new car, which are inevitable regardless the car type.

    They still use gas. And even if you try to run them exclusively on electricity, most of it comes from burning fossil fuels, so you’re probably not winning much. To actually put any dent, you need the electricity supplier to generate energy from clean sources like solar and wind. In short, a person would reduce CO2 much more by covering a roof with solar panels than by buying a hybrid.
