Imagine this: You live in greater Atlanta area and are interested in solar energy. You would like to know quickly what potential for electricity production the roof of your house or your apartment building has? Where do you go to find that information in 2 minutes? Right, nowhere…
In Vienna it takes you less than 2 minutes. The city just published its “Solarkataster,” an electronic map of the city where you can either zoom in on your location or type in your address. The website will then provide you not only with data about the sun’s angle and strength at particular days and times, but it will also tell you the potential for electricity production on your roof and calculate possible investments in solar energy. The website is based on overflights of the city with a laser-sensor conducted in 2007.
That was one year before Obama was elected president in the USA. Here we are still talking about whether or not solar energy is a feasible and valid energy source.
