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).

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.

- Corporate Average Fuel Economy (CAFE)
Federal standards that stipulate a target average fuel economy rating (typically expressed in miles per gallon, or mpg) to be met by passenger vehicles by a certain date. The most recent version of the CAFE law, pending passage by Congress, requires new cars, SUVs, and light trucks to average 35.5 mpg by 2016.
