Switching to electric cars will not improve the environment, despite the fact that such cars produce no harmful emissions. The electricity to run them world still need to be generated from power plants, the majority of which burn such fossil fuels as coal, oil and natural gas. Any reduction in fossil fuel demand at gas stations resulting from the replacement of internal combustion engines with electric ones would be reversed by a commensurate demand for more energy from our nation’s power plants.

Which of the following, if true, would most weaken the above argument?

A. The nation’s power grid would need a massive restructuring if it is to generate the energy needed to power vehicles that run on electicity.
B. Electric vehicles are significantly more energy-efficient than their gasoline powered counterparts.
C. Coal is a far less environmentally-friendly way to generate energy than is natural gas.
D. Studies indicate that most drivers would be reluctant to switch from gasoline –powered to electric vehicles.
E. Hybrid vehicles offer a more practical short-term alternative than do vehicles that run solely on electricity.

So think the answer here is B because if electric cars are significantly more energy efficient, then the electricity that they require is less than the gas required for the same amount of efficiency, thus reducing the amount of natural fossil fuels necessary?
