Wind turbines in the UK are generally installed on very low towers. This makes sense because of the different wind profile at exposed wind sites on hilltops. It reduces the cost per turbine and has an impact on the construction costs.
The best sites in Germany are close to the coastline. The country may look as if it would be easy to install wind turbines there, but this is a misperception. The ground is quite often swampy so that deep concrete piles have to be driven in the ground.
Because of the lower wind speeds, wind turbines are generally sold in Germany with larger diameters per rated power. And wind farm sizes are generally much smaller. This results in a weak negotiating position for the wind turbine buyer.
