Questions and Answers

Why is it important to worry about the energy driving transportation systems?

  • The carbon in petroleum-based fuels is not oxidized during combustion.
  • The energy used in transportation has no impact on the environment.
  • The size and growth of transportation systems lead to massive carbon dioxide emissions. (correct)
  • Transportation accounts for a small percentage of worldwide greenhouse gas emissions.

    • What is the primary reason behind the concern about the increasing global demand for fuel?

  • As developing countries motorize, it will challenge greenhouse gas concentration control. (correct)
  • More fuel demand will have no effect on the atmosphere.
  • It will lead to a decrease in transportation systems.
  • The demand for fuel will lower greenhouse gas emissions.
