You should very well play the role in it as well. On top of that there are many other benefits of electric cars. They save on the petrol, whose prices are hiking each day, so monetarily, they are a better option. Environmentally, you will save on emitting pollutions as well as not deplete the renewable resource. Also it would help the gross income of your country increase as it will cut down on the imports of petrol, by which the countries rich in oil are having all the fun just because you want your comfort right in its place.
It does not promise you no-energy wastage, but it definitely is less dirty than the fuel consuming cars.
