I am sorry to say but what you mention in the lead is totally wrong. "We all know that electric powered vehicles are currently the best option when it comes to efficiency and protecting the environment." This is just not true. Electric power is generated mainly by burning fossiles just as a simple car engine only a bit more efficient. Delivering electric power has losses. Electric motors are not 100% efficient also. (Not mentioning huge batterie banks full of acids, lead and other "environment-friendly" materials.) The only thing which is good to the environment is NOT burning fossiles. Like building more wind power generator.
