Weird Environmental Science

The Associated Press reports on a study published in the Proceedings of the National Academy of Science which finds so-called "green cars," those running on batteries charged from the power grid, are actually more harmful to the environment than gasoline powered cars. 

This is true if electric cars operate in an area where most electricity is generated by coal-fired plants. If most power in your area is generated by natural gas, hydroelectric, wind, or solar sources, the electric car is cleaner than its gasoline powered peers. And ethanol is more polluting than gasoline.
