Charging Your Electric Vehicle with Solar Energy

Here’s a good article that analyzes the eco-friendliness of electric transportation that makes a point that I try to emphasize in my discussions on the subject: the EV “selection effect.” The vast majority of EV buyers at this point make their decision based on their interest in protecting and preserving the environment, and are extremely likely to charge their cars with solar energy, i.e., “green people buy green cars and green electricity.”

The article (and those it links to) makes the usual error, however, of discussing the average preponderance of coal in the grid-mix, as if this has bearing on the validity of EVs from an ecologic standpoint. The real question, of course, is: Where does the energy come from when you put an incremental load on the grid in most portions of the U.S. in the middle of the night? And the answer, because it’s the least expensive form of baseload, is coal.

But again, let’s not lose sight of the selection effect. As the gentleman interviewed says, “At least 56 percent of all EV owners in California, who make up 35 percent of EV owners in the U.S., either have or are installing solar panels in their homes, according to the Center for Sustainable Energy, California.”
