Introducing the world's first silent wind turbine

Renewable Energy Solutions Australia (RESA) is the owner of the world's most advanced silent wind turbine known as the Eco Whisper Turbine®.


2 models

There are 2 models: the Eco Whisper Turbine 650 that generates up to 20 kW (now selling) for commercial/industrial applications and the Eco Whisper Turbine 325 that generates up to 5 kW (in development) for smaller or residential power needs.


30% more power

The award winning Eco Whisper Turbine™ features a unique 30 blade design that is virtually silent and up to 30 percent more efficient than traditional noisy 3-bladed designs.


Smaller footprint

  • The Eco Whisper Turbine 650 stands 21.1 m high. It can achieve high energy outputs in low or high winds with a footprint of only 21 m2. In comparison, solar requires 250 m2.
  • The Eco Whisper Turbine 325 stands 19.6 m high. It can achieve high energy outputs in low or high winds with a footprint of only 19.6 m2. In comparison, solar requires 50 m2.


Proven & now selling

Following two years of development and testing in Australia, Eco Whisper Turbines has successfully completed the commercial installation of the turbine in Tullamarine. Read the media release.

Since its launch in October 2011, the turbine has attracted considerable interest. It was a finalist in the 2011 Australian Cleantech Awards and was recently awarded a $250,000 commercialisation grant from the Australian government.

More recently, the turbine was awarded the 2012 Queensland Premier's Sustainability Award in the Innovation in Technology category.



The Eco Whisper Turbine is designed to offset small to large energy requirements. It is suited to:


  Commercial, manufacturing and industrial sites

  Airports, ports, mining resource facilities, council sites and industrial development sites.


  Urban development sites

  Shopping centres, industrial parks, schools, universities and more.


  Agricultural/rural sites
