EVs: Not So Green After All

The Australian has reported the results of a fascinating British study. It turns out that electric cars (EVs), those holy icons of the Green religion, may actually produce more atmosphere-destroying emissions over their lifetimes than regular, gasoline fueled cars — when you do the commonsense thing and factor in the energy it takes to produce the necessary batteries.

To be precise, the study (which was funded by the Low Carbon Vehicle Partnership, a group that is, in turn, supported by both the British government and the British car industry) showed that the average EV would have to be driven over 80,000 miles for it to produce a net savings in carbon dioxide over the standard internal combustion engine. Considering that EVs have limited ranges (they average about 90 miles per charge), it is not clear that many EVs will last that long.

This study was the first to look at the whole lifecycle emissions of EVs, including their manufacturing, driving, and — please note — the tricky matter of disposal of their used batteries. These batteries are the culprits. They contain metals that are expensive to produce, and they have to be replaced every few years.

The study found that a mid-size EV produces about 23.1 tons of carbon dioxide during its lifetime, scarcely less than the 24 tons produced by a regular, gasoline powered car. This is in part because the emissions from manufacturing EVs are about 50% higher than those from manufacturing regular cars.

What the British Department for Transport will make of the report it called for is anyone’s guess. The Department is currently lavishing $7,700 grants on people who buy the damn things.
