These new windmills are BIG, around 250m: e.g. 167m turbine height Thi + 80m Rotor diameter / 2. Zoom in on ones in your area.

How profitable are windmills in Germany, from EEG tax money ?

"Installed power", Installierte Leistung is the maximum a windmill can generate, at windspeeds around 40 km/h. Over a whole year, the electricity actually generated might be 20 % to 40 % of the maximum. This is called "yield" (Ertrag) or "capacity factor". It depends on actual windspeeds at a given site, and on turbine type and height.

In Germany, wind power, solar power etc. are subsidized with around €20.000.000.000 per year out of the Federal Budget, tax money; see Erneuerbare Energien Gesetz . New onshore wind turbine owners get about €70 per MWh from the EEG, guaranteed for 20 years. As I understand it, if the market price is 1/4 of that, the taxpayer pays the remaining 3/4. But only the windmill owners (and a few politicians) know how much EEG tax money each windmill gets. This makes intelligent planning impossible.

https://wind-data.ch/tools/powercalc.php shows interactively how power production MWh/year can be calculated from windspeed distribution and a power curve for a given turbine type. Run some examples, with Weibull parameters A = 1.127 * average windspeed and k = 2.5.
