Abstract
In order to analyze the potential of wind power generation in Japan, we calculated annual amount of power generation and economical balance of wind power generation considering meteorological conditions and social characteristics in 152 municipalities where meteorological observatories were placed. Meteorological conditions include the average of wind velocity and the risk of lightning strike and storm. After evaluating wind power generation projects based on the economic method using NPV (Net Present Value) indicator, we showed the ratio of municipalities those could offset deficit through the system of taking up electricity and the emissions trading as policies for wind power use popularization. The average of wind velocity was indicated to be the dominant factor for the economical balance followed by the price of taken up electricity in every municipality.
