Quiet Revolution, a UK based renewable energy company, is receiving a capital injection to the value of £7m GBP. RWE Innogy GmbH based in Essen, Germany and part of the RWE Group has invested £6m and £1m has come from private investors.”We are delighted to be working with RWE Innogy to deliver efficient local wind energy. This investment will allow us to rapidly expand our production capacity tomeet demand, and develop a range of new products to satisfy needs in a global marketplace” says Robert Webb, Chief Executive Officer and co-founder of quietrevolution.

The 6kW qr5 triple-helix-shaped wind turbines are five metres high and just over three metres wide. The turbines are vertical in orientation and generate electric power by turning around their own axis. They are especially suited for local energy production in built-up areas and can be installed either on buildings or as a standalone turbine.

“The purpose of our involvement,” adds Crispin Leick, head of the RWE Innogy Ventures Division, “is to take this promising technology towards mass production, so that it will become commercially usable.”

Prof. Fritz Vahrenholt, Chief Executive Officer at RWE Innogy says “The local supply of electric power to individual buildings from renewable energy will become increasingly significant. Small wind power units on roofs can make a major contribution to this goal, especially in places with insufficient sunshine, so that photovoltaics would not be efficient enough.”

Around 30 qr5 turbines to date have been produced and installed at clients’ sites around the UK, and a further 45 have been sold and are at the manufacturing and installation stages.
