What type of transportation uses the most total energy?
-
Correct!
By far the largest share of energy in transportation is consumed by cars, light trucks, and motorcycles—about 58% in 2012, followed by other trucks (21%), aircraft (9%), boats and ships (3%), and trains and buses (3%). Pipelines account for 3% and military uses for 2%.

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.

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.

Correct!

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.

On average, which is most efficient in coverting heat into electic power?
- Coal boiler power plant
- Natural gas-fired turbine power plant
- Natural gas combined-cycle power plant
-
Sorry, that’s incorrect.
On average, a typical coal-burning power plant in 2013 was about 33% efficient in converting heat energy into electrical power. A gas-fired plant was about 42% efficient. And in natural gas combined-cycle power plants—in which waste heat from a natural gas turbine is used to power a steam turbine—generation may be as much as 60% efficient.
