The Wall Street Journal ran a silly opinion column by long-time anti-environmental gadfly Bjorn Lomborg last month saying that electric cars are worse for the environment than conventional internal combustion powered vehicles.
Luckily, we have watchdogs like Jim Motavalli who wrote a blistering rebuttal published on plugincars.com.
Motavalli cites extensive research by the Argonne National Laboratory, studies in the Journal of Industrial Ecology and other sources to rebut the WSJ article. Among other misleading statements, Lomborg estimated the carbon footprint for electric vehicles with a life expectancy of 50,000 miles.
But both the Chevrolet Volt and Nissan Leaf come with 100,000-mile powertrain warranties, so they're not likely headed for the junkyard after 50,000 miles.
On the bright side, the Journal story recognizes something we’ve known for a long time, that cleaning up our electricity grid will make EVs even better for the environment: “the combination of EVs with clean energy sources would potentially allow for drastic reductions of many transportation environmental impacts, especially in terms of climate change, air quality, and preservation of fossil fuels.”
