Abstract
This study manifests the transitional process of social image on wind power generation in view of social expectation or discussions. We extracted 2, 604 related articles out of Asahi News Papers (# of data is 4, 817, 940) published betweenAugust 1984 and December 2005 to grasp the transition of their contents of expressions. As a result, social image on the wind power generation changes from period of technical establishment (till early 1990), period of icons of environmental preservation to the recent period of superficial signs to which concrete meanings, such as generation systems or contribution for environment, are rarely reflected.
