Wind energy

5 February 2015

Wind energy (or wind power) is a form of renewable energy that uses airflow to generate electricity.

Wind turbines are typically about 120 metres high to capture stronger winds and their blades span about 45 metres.

A single small wind turbine can generate electricity for a single home, while many larger turbines lined up together on wind farms can generate electricity for the grid.

How does wind power work?

The wind turns the blades of a wind turbine that is connected to a generator, and the generator converts the wind’s kinetic energy to electricity.

 

How do Wind Turbines work?

The amount of wind power in Australia is likely to increase in the coming years. Here are some interesting wind energy facts:

  • Offshore wind farms can produce 50 percent more electricity than those onshore, but they are much more expensive to build.1
  • Developments in technology have cut the cost of wind power by 80 percent over the past 25 years.2
  • By 2050, wind energy could supply up to 12 percent of global demand for electricity.3
