Study: Your all-electric car may not be so green
By Seth Borenstein, AP Science Writer.
If your all-electric car gets its power from coal, new study says it is dirtier than gasoline.
People who own all-electric cars where coal generates the power may think they are helping the environment. But a new study finds their vehicles actually make the air dirtier, worsening global warming.
Ethanol isn't so green, either.
