Abstract: Wind power is being seriously considered as one of the most promising of the renewable energy sources in the world, such us UK, Denmark, China and etc. The attractions of wind power are partly due to its environmental benefits and recent development in technology, which offer the prospect of a competitive source of energy. Although there are widespread opportunities of wind power around the world, this wind power project is the first of this kind in Hong Kong. As we have no hands-on experience, there are several critical issues addressed, namely wind data collection, wind characteristic examination, wind power and energy estimation, economic assessment and engineering design. Wind is one of the renewable and free of charge energy sources in the world. In Hong Kong adoption of wind power is brand new and it is worthwhile to explore its feasibility to our power industry. In order to explore the applicability of wind power in Hong Kong, a site has been selected for trial study on Lantau island since early 1997, which is near Po Lin Monastery at Ngong Ping Village. From technical point of view, the average wind speed at project site is 5.3 m/s that is marginal higher than cut-in speed of the wind turbine. The annual estimated energy production is around 245,000kWh that is not good enough for Buddha Statue whose annual energy consumption in 1998 is around 330,000kWh. Therefore, the above figures indicate that one Nedwind 25 wind turbine erected at project site is not sufficient to supply power to Buddha Statue. On the other hand, this turbine or a smaller wind turbine can be considered to supply power for the floodlights. It is believed that Po Lin Monastery may find attractive from spiritual point of view. From economic point of view, the cost of energy (COE) of the wind turbine in this exercise is much higher than that of a modern fossil fuel generation plant. Moreover, it appears that the cost incurred could not be compensated by the benefits gained. Consequently, it would be doubtful for decision-maker to give green light to the project. From author's point of view, a more comprehensive study is required in order to determine whether we should erect a wind turbine in Hong Kong. A second or a third site for further measurement is necessary and the wind database created and experience learned in this study form a good base for further development of wind power in Hong Kong.
