Wind energy is the energy of moving air. This energy can be transformed into electricity, fed into the grid and then used to power our homes and industries. We have been generating electricity from the wind for more than 100 years but there has been a resurgence in the last 40 years. Wind power is back in favour for some very good reasons.

There is an everlasting supply of wind energy and in harnessing the wind, there is no pollution, no greenhouse gases – just a clean, renewable, sustainable energy supply. Throughout the world wind energy technology is well proven and cost effective. It is one of the fastest growing electricity generation technology.

What is a Wind Farm and a Wind Turbine?

A wind farm is a group of wind turbines and their associated infrastructure. Each individual wind turbine consists of a foundation, tower, nacelle and a rotor. A typical, mid-sized wind farm suitable for Victorian conditions consists of thirty to sixty wind turbines. The wind turbines are typically 100 to 150 metres high to the tip of the blade sweep and mounted on towers from 80 to 100 metres high.  Wind turbines in the planning and development phase are between 150 and 200 metres high to the tip of the blades consistent with international technology standards.
