Being fully electrical, these kinds of vehicles produce no emissions, except what is released by the power plants.
However, energy sources such as hydroelectric, nuclear, wind and many others produce clean energy.
So, based on your energy source, that type of vehicles can be totally clean and green.
The increased performance is due to the fact that electric motors do not acquire carbon buildup and other problems as would a gasoline or diesel engine.
Fewer parts require less maintenance and offer a lighter vehicle.
Electric motors also accelerate faster because there is no lag time between pressing the accelerator and the engine recognition.
(Link: Finally let’s look at how they work.) EV’s work by using electricity instead of gasoline or diesel and they also use a different kind of motor, other than that they are almost exactly the same as any other vehicle.
Just to look at how the motor works, imagine a fan, the electricity comes in and it makes it into an electromagnet and in turn allowing it to spin due to the properties of magnetism.
To sum that up, they take electrical energy and convert it into mechanical energy.
According to the US Department of Energy “Electric vehicles convert about 59–62% of the electrical energy from the grid to power at the wheels—conventional gasoline vehicles only convert about 17–21% of the
