The business of renewable energy is really booming nowadays when global warming and fossil fuel limitation have been becoming critical issues. Energy security is of great importance to any socio-economical development. Phu Quoc island, the largest island in the south of Vietnam,is developing at a rapid pace. However, power shortage is currently an obstacle to this fast development. Wind energy is seen as an effective solution to the serious power shortage thanks to the abundant wind resource in Phu Quoc. In this book, the hypotheses about feasibility of the wind farm project and possible business model for Finnish investors were discussed and then checked by going to the field, talking to the people, analyzing and interpreting the gained information. The results showed that wind energy is being developed with more and more effective incentives and legal framework to be issued in future. It is feasible to develop a wind power project in Phu Quoc thanks to sufficient wind resource and encouraged investment policies. A business model has been proposed including entry mode, project type and specific location.
