according to this the total land area of built up human development and infrastructure is also around 1%, seems a hell of a lot easier to mandate every building have a white roof. Especially considering most buildings have black roofs, it will be even more of a difference. Also will reduce energy consumption from AC because, as said in the article buildings panted with it have reduced need for cooling.
Roads could also maybe be painted or have a whiter material used, might make it harder to drive though
I think white roads could be a problem with snow, usually the only good way to find the road in a snowstorm is to look for the darkness, no darkness and you can't tell the road from the ground covered in snow.
Oh yeah that's a good point too. Probably not actually practical. Also the super special paint almost certainly would not take being driven on by thousands of vehicles very well.
