This article compares the social costs of electric vehicles with those of c
onventional, thermal vehicles for typical passenger use in the Ile-de-Franc
e region (Greater Paris), a case of particular interest because nearly 80%
of the electricity is generated by nuclear power plants. A four-seat electr
ic car is compared to a new conventional car of the same make and model; fo
r the latter both the gasoline and the diesel version are considered becaus
e almost half of new car sales in France are diesel. These results are also
compared to typical existing diesel and gasoline vehicles in the current F
rench fleet. The methodology developed by the ExternE (External Costs of En
ergy) Project of the European Commission is used to estimate the costs asso
ciated with atmospheric pollution due to power plants, refineries and tail
pipe emissions. Our discussion of externalities is limited to air pollution
thus excluding others such as costs associated with noise or accidents. Ou
r results imply that the external costs are large and significant, even whe
n one considers the uncertainties. If internalized by government regulation
s, these externalities can render the total cost of an electric vehicle mor
e competitive with that of currently available thermal vehicles in large ur
ban centers if the electricity is produced by sources with low pollution. H
owever, the current generation electric vehicles are so expensive that inte
rnalization of pollution damage would not give it a very clear advantage. (
