So all this study actually did was estimate roof coverage in Switzerland using a new method? The figure is pretty easy to estimate anyway, but they used the Machine Learning OMG method? > What if half of Switzerland's rooftops produced electricity? What would be interesting if someone did some work and actually worked this out, no? How would infrastructure change? What backups would be needed? Could surplus, if any, be used for anything? Could you connect to other countries in new ways? How would employment be effected? Supply chains for materials? Reflected and absorbed energy would change city heat sinks how? Would smog change at all?
