Our history
of success
It took us almost 10 years to reach this current point as a small wind manufacturer. Our tremendous journey has been full of trial and error, continuous R&D, rigorous testing of new hypotheses, application of innovative materials, and non-stop invention — all to finally succeed in creating Darrieus wind turbines with industry-leading energy conversion efficiency, a low cost of ownership, and outstanding applicability to all kinds of usage scenarios.
The first commercial vertical wind turbines, based on Georges Darrieus’ invention, were deployed in the United States back in the 1980s. 30 years later, Valerii Nebesnyi, the founder of ANEM and a serial inventor, revolutionized the original concept paving the way, to the emergence of a patented technology for building turbines that are considerably lighter than both traditional propeller-type turbines and the rigid vertical-axis Darrieus turbines. Key milestones
Today, our family of small wind turbines — based on our proprietary designs and patented technical solutions — offers consumers and energy operators worldwide a great opportunity to start reaping the benefits of renewable energy without making million-dollar investments.
