Electric Vehicles

Fuel Transportation cost: Many people do not consider this. The gasoline that you get in your gas station has been pumped, processed and transported from an oil-well elsewhere. All these process involve pollution at some level. On the other hand for EVs the electricity is transmitted from Power plant to your house through wires and this set-up is already established.
Energy Regeneration: Another that is only possible with EVs is Electricity re-generation. This does not add much but still it has a small impact on making the EVs greener.
So to conclude EVs are sure to be a lot greener than ICE if we shift towards renewable energy for electricity production and practice safe disposal of batteries.

What is the difference between a Hybrid Vehicle and an Electric Vehicle? 

Some people tend to use the term Hybrid Vehicle and Electric Vehicle interchangeably which is not the case. Both have entirely different meaning. To put it in lay mans terms if the vehicle runs both on Electricity and gas then it is a hybrid vehicle, if it runs only on Electricity and cannot run on gas then it is called as Electric Vehicle. You can make sure if a car is EV by checking if it has a fuel tank, if there is not fuel tank then the car is surely an EV.
Both EVs and Hybrids have they own significance, A hybrid car can rule out the disadvantages of EV like fuel time, short travel range etc but since it has the hardware for both ICE and EV these cars are normally costly. Hybrids cars are normally aimed to increase the efficiency of a Car by leveraging a Motor to run the car at low speeds.
