How are battery electric vehicles and hybrid vehicles different?
- Battery electric vehicles receive charge from the electric grid, and hybrid vehicles do not.
- Hybrid vehicles have a gasoline engine and an electric motor that can supplement drive. Battery electric vehicles only have an electric motor.
- Hybrid vehicles consume petroleum onboard when the battery is exhausted. Battery electric vehicles do not consume petroleum onboard.
- Battery electric vehicles emit no carbon dioxide. Hybrid vehicles do emit carbon dioxide
- C and D
-
Sorry, that’s incorrect.
Battery electric vehicles have only a motor and battery, they recharge from the grid and their carbon emissions depend on the energy used to generate the electricity they use. Hybrid vehicles have both a gasoline engine and an electric motor, and use petroleum onboard when their batteries are exhausted. Some hybrid vehicles can charge from the grid and others cannot.

- Natural Gas
A gas mixture that occurs naturally in underground deposits. It is composed primarily of methane and may contain other hydrocarbons, carbon dioxide, and hydrogen sulfide. Commonly employed as a fuel for electricity generation, it is also used for space heating, industrial processes, and as a starting material for the manufacture of chemicals and other products.
