What You Need To Know About Energy
What do you know about energy?
On average, how much solar radiation reaches each square meter of earth?
-
Sorry, that’s incorrect.
On average, even after passing through hundreds of kilometers of air on a clear day, solar radiation reaches Earth with enough energy in a single square meter to run a mid-size desktop computer-if all the sunlight could be captured and converted to electricity.
-
Correct!

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.

- Cap and Trade
An approach to control emissions of a given pollutant by setting a limit, or "cap," on the total amount permitted to be released. Industries, utilities, and other groups are required to purchase, or may be given, "credits" that establish allowable quantities of emissions. Unused credits may be sold in a resulting market for trading emissions allowances.
