The same is already true in Germany, despite its somewhat lower wind penetration than in Denmark (11% of electricity produced, vs 25%)
11%? Methinks you quoted the 2006 figure for all renewables. The 2007 figure for wind alone is 6.3%.
Also, before someone spins the poll numbers in your fourth graph the wrong way: that the overwhelming support for wind power is the lowest in Germany should be seen in the context of present level of wind power installations and "large increase" in the future. *Lunatic*, n. One whose delusions are out of fashion.
