As stated in the article, the roadway is just sitting there and making it a solar roadway doesn't take up anymore real estate. I think it does make sense in areas where there is not a lot of real estate. But with the cost being 13 times more than solar rooftops, it may be wiser to spend money on Tesla's solar roof technology first.

I commend France's commitment to turning 1,000 km of roadways into solar roads. This will at least help the technology get further down the road (pun intended) and hopefully further improve the technology and bring down costs. The article did not state the cost difference between putting in a traditional roadway versus a solar roadway.

Thanks for commenting!

Steem on,
