Surprise, surprise! A new study has found that in many cases electric cars actually do more damage to the environment that gasoline-run vehicles.
The study has a lot of uncertainties, and is based largely on statistical analysis, which I always find suspect. In addition:
The study’s biggest caveat, acknowledged by the researchers, is that they don’t consider a full “lifecycle” analysis of emissions—so things like making the car, drilling for oil, or transporting coal aren’t included in the environmental costs. Some previous work has found that EVs are cleaner than gas cars when you consider the totality of impacts; others have found that’s only true if the power grids that charge EVs are also clean.
Notice how they also don’t mention any of the environmental costs for making the batteries and components of an electric car. I wonder why.
Nonetheless, this study illustrates again why we should never rely on the opinions of politicians in these matters. They know less than nothing, and always base their policy on raw, simplistic emotions rather than complex knowledge. Better to let freedom, and the market decide. It always looks for the most efficient way of doing things, which in the end is always going to be better for the environment.
