On one side Innovation, innovation systems and knowledge management are two topics have been discussed so much by scholars before. The advantages gained through knowledge management by fostering innovation which entails competitive advantage. On the other side, an emerging interest has represented the relationship between the renewable industry and environmental innovations. The oil crises and some forum discussion of environmental impact have fuelled the interest for Renewable Energy especially on wind energy. Most likely there hasn’t been any research knowledge management in wind power companies which is an emerging and terribly needs knowledge to innovate and bring more products. As a result there is a need to look more into the role of knowledge management in wind mill companies and explore how innovation can be triggered by successful knowledge management and how this process provide competitive advantage in wind power industry.
