Heat

The solar energy that reaches the surface of the earth (around 100 W/m2 in Western Europe) can also be used for heating purposes, via passive (the capture of irradiation via windows and building mass) or active technology (e.g. solar collectors).

The functionality of solar heat depends strongly on the local circumstances (orientation and angles of obstruction by the natural and technical landscape, greenery and buildings) and hence, can only be charted on small-scale potential maps. In relatively cold climates (average temperature below 20°C) the use of solar heat is recommended: it is available everywhere and cheap.
