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.

What is the primary energy user in the industrial sector?
-
Sorry, that’s incorrect.
A few industries use a very large share of energy in the industrial sector. Petroleum refining is the principal consumer, with the chemical industry a close second. Those users, plus the paper and metal industries, account for 78% of total industrial energy use.
