What are ways that electricity system operators match power needs to generation on a day-to-day basis?
- Turning on or off adjustable, load-following generators
- Turning on or off short-term "peaker" plants
- Initiating demand-response actions, such as adjusting thermostats for customers who have agreed to it.
- Initiating energy storage, such as pumped hydro or battery storage.
- All of the above
-
Sorry, that’s incorrect.
Load-following and peaker plants, demand-response and energy storage are all ways that grid operators can adjust generation to meet demand.

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.

True or false? Hydraulic fracturing and horizontal drilling have increased oil and gas production in the U.S.
-
Correct!
Extraction of "tight" oil—light crude oil contained in geological formations of shale or sandstone—accounted for only 12% of total U.S. oil production in 2008. By 2012, it made up 35%, and is predicted to rise to 50% in the near term.
