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.
