What You Need To Know About Energy
What do you know about energy?
Energy intensity is a measure of:
- The amount of energy used by a nation per unit of GDP
- The amount of energy contained in a given amount of fuel
- The amount of electric current passing through a point
-
Correct!
Energy intensity is a measure of a nation's energy efficiency represented through energy use per unit of GDP (Gross Domestic Product).

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.

True or false? Fuel cells store energy.
-
Sorry, that’s incorrect.
Fuel cells are an efficient way to convert hydrogen to electricity, but the energy is stored in the hydrogen.
-
Correct!
Fuel cells are an efficient way to convert hydrogen to electricity, but the energy is stored in the hydrogen.

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: 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.
