About WindGuard

Wind is – besides the sun – the only energy source for which one can predict today, what the price will be for the next few years, decades, centuries:

It costs nothing

With this advantage, wind will always play central role in every future energy concept. Only renewable energies can deliver a secure, responsible, cost effective energy supply in the long run.

With this central thought in mind, WindGuard founders Dr. Knud Rehfeldt, Axel Albers and Gerhard Gerdes, decided 25 years ago to tap into the potential of wind power and turn it into a viable source of energy production. The result was the foundation of Deutsche WindGuard in 2000. Ever since, in a complex energy market WindGuard is committed to providing extensive scientific, technical, and operational services which are unbiased and manufacturer-independent.


"Our goal is to ensure that in the future, 80 to 90 % of the global energy demand will be met by renewables."

Today, we offer investors and developers, manufacturers, decision makers in governments and businesses worldwide, extensive and independent expertise on all facets of wind energy. With about 200 experts at our headquarters in Varel and offices in Bremerhaven, Elsfleth, Norden, Gelnhausen and Berlin as well as in the United States, India and in China, Deutsche WindGuard as an owner-managed, medium-sized company offers more than 50 different services.

The extraordinary synergistic effects between departments combined with our worldwide playing field provide Deutsche WindGuard with a unique market sense. Internationally recognised accreditations and certificates add certainty and objectivity to the assessment of all project-related information. Our comprehensive universe of services reliably supports your projects along the whole value chain of wind energy: from the first feasibility studies to decommissioning. We reliably support the complete project lifecycle and ensure optimum performance from the word go – Onshore. Offshore. Worldwide.
