Electrically powered cars are absolutely worth it. For two reasons:

1. Better for the planet

Yes a little bit of a no brainer, but very critical. Humans are on a first class ride to self destruction, and one of the reasons as to why, is the abuse and exploitation of the planet. As it is, humans are being extremely ignorant of the state of health of our planet (May I remind you the only planet in our vicinity of the Universe, and as far as we know, the only planet capable of sustaining human life). It is not only a good deed, it is mandatory we be aware of the harm that we are inflicting on Earth, and be mindful of what we can do to minimize and even completely stop the harm. By cutting down on emissions, we are helping revive the planet, saving the health of our bodies, and being responsible with the resources that our Mother Earth has provided us, which brings me to my next point.

2. It is only a matter of time before we run out of our natural fuel sources.

Yes it may be a long time away before that happens, but shouldn't we as humans feel obligated, to not leave this mess in the hands of our Children, and Grandchildren? It would be completely irresponsible and counter productive, to not try to perfect Electrically Powered Cars, because we are going to depend on them in the future (That is if we survive that long).

No more gas is worth it. Electric cars would not pollute the air.
