What You Need To Know About Energy
What do you know about energy?
If electricity production wastes between 40 and 65% of the primary energy source, why is it used?
- Producing electricity is a way to store energy.
- Electricity production results in no harmful emissions.
- Electricity is a versatile energy carrier.
-
Sorry, that’s incorrect.
Most direct uses of primary energy are limited to generating heat and motion. Electricity, by contrast, is extremely versatile, with a wide range of complex applications.

True or false? Wind energy generation is increasing in the United States.
-
Correct!
In the United States, the amount of electricity generated from wind doubled between 2009 and 2014, and now makes up 18% of all renewable energy consumed and almost 2% of total U.S. energy use.

True or False: Burning coal in electric power plants is a major source of CO2 and other emissions. However, its use doesn't have negative consequences beyond the emissions caused by combustion.
-
Sorry, that’s incorrect.
Mining coal disturbs the land and modifies the chemistry of rainwater runoff, which in turn affects stream and river water quality.

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.
