Electric Cars Are Dirty

The naive thought is: electric cars have no exhaust, hence they are clean.

Wrong.

Electric cars drive on electricity, that is generated in power stations running on fossil fuel.

Richard Pike of the Royal Society of Chemistry provocatively determined that electric cars, if widely adopted, stood to lower Britain’s carbon dioxide emissions by just 2 percent, given the U.K.’s electricity sources. Last year, a U.S. Congressional Budget Office study found that electric car subsidies “will result in little or no reduction in the total gasoline use and greenhouse-gas emissions of the nation’s vehicle fleet over the next several years.”

Rather than powering your car, fossil fuel is used to power a generator in the power station. Next, the generated electricity is send down the wire to charge your battery. That charging-discharching cycle costs energy that wouldn’t be wasted if you would use fossil fuel to power your vehicle directly.

Theoretically, driving would be clean if the electricity would come from solar and wind. but that is not bound to happen any time soon. Not during the economic life span of your Prius.
