Automotive News reports on a new study that reveals what should be obvious to any educated person, that the real environmental benefits of electric cars can’t be realized as long as the cars are powered by electricity generated by coal.
“For electric vehicles to become a major green alternative, the power fuel mix has to move away from coal, or cleaner coal technologies have to be developed,” said Jared Cohan, the chair of a National Research Council report released on Monday called “Hidden Costs of Energy: Unpriced Consequences of Energy Production and Use.”
About half of U.S. power is generated by burning coal, which emits many times more of traditional pollutants, such as particulates and smog components, than natural gas, and about twice as much of the main greenhouse gas carbon dioxide.
Nuclear and renewable power would have to generate a larger portion of U.S. power for electric cars to become much greener compared to gasoline-powered cars, Cohan, who is also president of Carnegie Mellon University, said in an interview.
The development of sustainable, renewable and less-polluting sources of energy is still the brass ring that must be grabbed.
