Unclean at Any Speed - Why Electric cars don’t solve the automobile’s environmental problems

 IEEE Spectrum..."We wanted to make sure, since you love cars, that when you are on the road you are always looking environmentally friendly, and we decided to get you a car that would make you stand out a little bit." Mission accomplished.

The idea of electrifying automobiles to get around their environmental shortcomings isn't new. Twenty years ago, I myself built a hybrid electric car that could be plugged in or run on natural gas. It wasn't very fast, and I'm pretty sure it wasn't safe. But I was convinced that cars like mine would help reduce both pollution and fossil-fuel dependence.

I was wrong.

I've come to this conclusion after many years of studying environmental issues more deeply and taking note of some important questions we need to ask ourselves as concerned citizens. Mine is an unpopular stance, to be sure. The suggestive power of electric cars is a persuasive force—so persuasive that answering the seemingly simple question "Are electric cars indeed green?" quickly gets complicated.

As with most anything else, the answer depends on whom you ask. Dozens of think tanks and scientific organizations have ventured conclusions about the environmental friendliness of electric vehicles. Most are supportive, but a few are critical. For instance, Richard Pike of the Royal Society of Chemistryprovocatively 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."

Generous EV Incentives:Governments around the world offer drivers various inducements to buy electric cars. The monetary incentives in western Europe, for example, include direct subsidies on vehicle purchases as well as certain tax exemptions. Some of these countries also provide the drivers of electric cars with free parking and other perks.

Others are more supportive, including the Union of Concerned Scientists. Its 2012 report [PDF] on the issue, titled "State of Charge," notes that charging electric cars yields less CO₂ than even the most efficient gasoline vehicles. The report's senior editor, engineer Don Anair, concludes: "We are at a good point to clean up the grid and move to electric vehicles."
