Characteristics of wind energy at Ube city and Onoda city, Yamaguchi Japan were analyzed from the wind speed data during the period April 1972 to March 1982. Annual mean values of wind speed and wind power density vary considerably depending on the surface roughness of the surrounding ground and on the altitude or exposure of the mesured point. The western part of this region has higher wind power density than the eastern part. RYUO in the west has the highest mean value 83.3W/m^2 and MISAKI in the east has the lowest mean value 39.6W/m^2. The value at Mt. RYUO (136.2m) is 155.3W/m^2. Then this place is considered to be most favourable for the wind driven plant. Directional distributions of the wind energy are similar year by year. Prevailing directions are aligned in opposite directions, W〜NW and E〜ESE. The energy from the directional range of W〜NW are higher than that from E〜ESE. Therefore the wind energy flows from the west to the east of this region. It is possible to estimate the wind power density by the distance from Onoda port (the most western place).
