Reports section.

This web page contains links to reports and data which have been useful in constructing this website and in developing the computer programs available from it. The links are not intended to give a comprehensive cover of wind power issues but are concerned either with providing quantitative data on wind turbine performance or a technical report on some issue central to wind power. A simple star system is used to reflect our opinion of the reports and this includes a rating for widely quoted reports on important issues but which fail to fulfil their function.

Video section.

There is a huge collection of wind turbine videos on YouTube but this section contains just a few that seem particularly interesting in showing the features of a large wind turbine. The selection also contains an interesting news report on the development of wind power in China.

What's inside a wind turbine?
A good animation of the components of a wind turbine.
Promotional video showing components of a wind turbine with a gearbox.
Good animation of the gearbox and the pitch and yaw controls.
Inside the nacelle at start-up of a direct drive wind turbine.
Shows the many-poled generator stator and rotor - no gearbox.
CCTV news item on the wind power industry in China.
Interesting insight into the scale of wind power development in China.
