Some people say EVs are the future, however it's currently a huge step backward with the use of battery technology.
Specific energy (MJ/kg):
46 Gasoline
25 Coal
16 Firewood
0.936 Battery

Not yet mentioned is the efficiency of the engine or motor.
The fuel efficiency of motor vehicle engines is around 40%. This means the realized energy of gasoline is probably is closer to 18 MJ/kg. Electric motors have a much higher efficiency rate, about 85% as the mid range. So the realized energy of the current best batteries is probably closer to 0.8 MJ/kg.
Even with much higher efficiency motor, it is still well below.
Also to be considered, is that a typical electric engine can be about 50% the weight of a gasoline fuel engine for a vehicle. That can be about 250 lbs that could be potentially discounted in a comparison. The electric engine is more efficient by weight and use of energy, it's the batteries that have very low efficiency and specific energy.

This video states the specific energy of batteries is only ten times less than fossil fuels. In a direct comparison it's fifty to one-hundred times less.
There are other advantages because of the greater efficiency of electric motors and the motors weigh less, however that is not mentioned.
