Which of the following is the federal regulation established in response to the 1973-74 Arab Oil Embargo to improve the average fuel economy for cars and light trucks (vans, trucks, and sport utility vehicles (SUVs))

Corporate Average Fuel Economy (CAFE)

A hydrogen fuel cell produces greenhouse gases directly through its operation (do NOT consider products at any other step in the process, including when the hydrogen was produced).

False

Which one of the following means of powering transportation produces the least ancient carbon dioxide as a pollutant?

Hydrogen Fuel Cell

Hydrogen is considered by many to the "fuel of the future." Generating hydrogen for use in a fuel cell is a critical part of the process. Read through each of the following statements, selecting any/all statements that are correct.

Hydrogen is very energy rich, so one must be careful when refueling a vehicle. There are no natural reservoirs of hydrogen on Earth, so it all must be manufactured from other molecules. While water is an excellent source of hydrogen, most of the hydrogen produced today comes from natural gas.

Which one of the following is NOT a problem associated with electric cars (any of the types)?

Noise pollution

Electric cars are the future of transportation. Which ONE of the following statements most accurately describes the major problem with this technology.

The required batteries are heavy, reducing the range of the vehicle, as well as the problem of mining to produce all of the batteries.

Which of the following best describes the method of vehicle transport that is the most environmentally sustainable?

The use of a vehicle powered by hydrogen fuel cells because there are no carbon emissions

An internal combustion engine wastes most of the input energy as heat.

True

While an old technology, there are still a couple of structural benefits ("Pros") associated with the use of internal combustion engines in the transportation sector.

Use of a fuel with a very high energy density Fuel distribution infrastructure is already in place and is fuel is widely distributed and available
