This seems like a pretty impactful directive: France passed legislation demanding that new _and existing_ car parks of considerable size must install solar panels. This could generate power equal to 11 nuclear reactors.
I wonder how the costs and speed of realisation compare, against building 11 nuclear reactors. I'm guessing that solar is cheaper and faster to build too, but I'm unsure.

@guusdk speed might be slow, but cost is very low (to the people passing the law)
@Fishbowler I would guess that installing a lot of solar panels is faster than building a few nuclear reactors. You can parallelize better, and I assume that the know-how is a lot more accessible/available.
@guusdk @Fishbowler you'll need both anyway, unless you also install massive batteries. Otherwise there's way too much energy during sunny days and way too little at night.
