..."The Enercon E-126 is a wind turbine model manufactured by the German company Enercon. With a hub height of 135 m (443 ft), rotor diameter of 126 m (413 ft) and a total height of 198 m (650 ft), this large model can generate up to 7.58 megawatts of power per turbine. The power output of the generator was changed from 6 MW to 7 MW after technical revisions were performed in 2009.
The weight of the foundation of the turbine tower is about 2,500 t, the tower itself 2,800 t, the machine housing 128 t, the generator 220 t, the rotor (including the blade) 364 t. The total weight is about 6,000 t. The first turbine of this model was installed in Emden, Germany in 2007. The list price of one unit is $14 million plus install costs."...

In 1941 the Smith-Putnam wind turbine[2], the world's first megawatt-size wind turbine, was connected to the local electrical distribution system on Grandpa's Knob in Castleton, Vermont, US. It was designed by Palmer Cosslett Putnam and manufactured by the S. Morgan Smith Company. The 1.25 MW turbine operated for 1100 hours before a blade failed at a known weak point, which had not been reinforced due to wartime material shortages. It would be the largest wind turbine ever built until 1979.[3]
I don't see this technology as being sustainable, maybe they figured that out back then, and we forgot....
..."Cumulative operational and maintenance costs of wind turbines are significant and can equal 65%-95% of a turbine’s investment cost over the assumed 20 year lifetime of the turbine. The cost of unscheduled maintenance is difficult to measure industry-wide, but some studies suggest that it accounts for 30%-60% of the total O&M cost, and that it generally increases over time as a wind turbine ages"...
The Dutch are installing these E126 machines in the Noordoost polder. They are planning to have 6,000 MW of onshore wind power by 2020 and 4,450 MW of offshore wind power by 2023.
EWT is a Dutch wind turbine manufacturer that operates word wide including the US and Alaska. Much smaller turbines than the E126 - usually just under 1 MW.

There are big plans to install multiple large windmill parks on the North Sea (initiative of the government in cooperation with some energy companies) but the Dutch are not much fans of windmills at land (spoils the views -_- ).
We do have some manufacturers of windmills, but we do not have those big guys made in the Netherlands (as far as I know).
