If I was a French taxpayer, that would be my criticism of the project. Expanding the use of Tesla's new rooftop systems would seem to be more economically feasible.
Being a U.S. taxpayer and a contractor, I have seen the U.S. government spend $20 million and receive absolutely nothing in return. You would think that would upset a U.S. taxpayer.
It will be interesting to see if this article (project) gets comments from French citizens.
Steem on,
Mike
