Unscramble the Blue Letters

Then you are left with the need for electricity. In principle, there are several ways to get renewable electricity, but how many bluigidns do you know which have a wldnimil on the roof or a water power plant in the garden? Probably not so many, because usually, it doesn't make ssene. But the sun provides abundant energy to our roofs and facades. The potential to harvest this energy at our buildings' surfaces is enormous. Let's take Europe as an example. If you would utilize all areas which have a nice orientation to the sun and they're not ovlery shaded, the peowr generated by photovoltaics would correspond to about 30 pecernt of our total energy demand.

Then you are left with the need for electricity. In principle, there are several ways to get renewable electricity, but how many buildings do you know which have a windmill on the roof or a water power plant in the garden? Probably not so many, because usually, it doesn't make sense. But the sun provides abundant energy to our roofs and facades. The potential to harvest this energy at our buildings' surfaces is enormous. Let's take Europe as an example. If you would utilize all areas which have a nice orientation to the sun and they're not overly shaded, the power generated by photovoltaics would correspond to about 30 percent of our total energy demand.
