Toora wind farm

Pictured are five of the twelve wind turbines of Toora Wind Farm in South Gippsland, Victoria, Australia, operated by Stanwell Corporation Limited.

Each wind turbine stands on a steel tower 67 meters high. The glass fibre reinforced epoxy blades are 32 meters long, rotating clockwise at a maximum 21 revolutions per minute (thus, by my calculations, the outer tip of each blade hurtles around at a maximum over 250 km per hour).

Each turbine generates as much as 1.75 megawatts, giving the Toora Wind Farm a total generating capacity of 21 megawatts. The facility’s average annual energy output is 65,000 megawatt hours — enough to power 6,600 average homes per year.
