Electric Vehicles:  A Better Environmental Choice

by Johan Young

According to Transport Watch, only about 30% of the energy generated by a power plant in fact reaches the vehicle because of losses in the transmission toute.  Of the energy delivered to the vehicle, 20% is then lost to the batteries and electric motor. This means that most EVs are only about 24% efficient.
