I also noticed that a number of EV charging points have been installed across Paris since my last visit there 2 years ago, with EVs parked and charging. I found out that Paris has introduced an electric car sharing program and through my experience and judging by the EVs which I saw in the streets, I can say that it's being used quite a lot.
In the past 2 years a lot has changed in Paris and now it has become more Green!
Since I happened to be in Paris in December 2015, when the 2015 United Nations Climate Change Conference talks were being held, I was lucky enough to see a large display of Photo-voltaic panels installed in Champs Elysees serving as a demo to the public on the use of the sun to generate electricity.
I also saw a number of new Hyundai ix35 Hydrogen fueled cars (to be used as Taxis) just in front of the Eiffel Tower. Some more details on this initiative can be found here.
