Here is an interesting paper on the cost of EVs:

Quote12. Aside from cost, the mass and bulk of an EV battery pack constrain its power and
energy storage capacity. A high-performance (100-W⋅h, 250-W/kg) battery pack with an
energy storage capacity equivalent to only one U.S. gallon of gasoline would weigh
nearly 746 lb and occupy a volume of 47 gallons. Such a battery pack would provide
85 kW (113 hp) of power.
The increased vehicle mass associated with the large battery
pack would consume more energy to move the vehicle. Although lightweight materials
can be used to reduce vehicle mass, their use also increases a vehicle's cost.

Without the battery issues, an EV looks attractive.
