	Used this as a source to locating a relatively new windpark to look up and compare with a nuclear propaganda video. Siemens 3.6 & 6MW does very well against new Gen III projects, alot cheaper - which makes me think we'll finally see energy prices go down some as wind and solarpower emerges properly.
	Used for debate

	"25 Nov 2011 All 140 monopiles and transition pieces are in place. Turbine installation resumed in September.122 turbines are installed and 83 have exported electricity. Both offshore substations were energised earlier this year and two of the three export cables and all the array cables are now in place. All 140 turbines should be installed before the end of 2012."
