This article addresses the question of how policymakers could deliberately influence processes of technology development. Using the development of wind turbines in Denmark as an example, the article describes the frames of meaning guiding the actions of those involved in the three subprocesses of policymaking, the generation of new technologies, and the management of the firms that bring new artifacts to the market. The three types of actors share an interest in one notion: the meaning of a technological artifact. This notion, however, plays a different role in the respective frames of meaning of the actors. For policymakers and managers, it is an instrumental notion. For technologists, it provides guidance to their activities. The shared interest affords the possibility of reaching common action with only congruent (not necessarily shared) meanings. Interactive forms of technology assessment can play a central role in bringing about such congruent meanings and thus in influencing the generation of new technologies.For better or worse, technology thoroughly permeates our societies. Technological developments have brought many blessings but also many threats. The desired or promised blessings do not always materialize, and preventing or reducing threats poses challenges that all too often cannot be met satisfactorily. This lack of success in effectively controlling technological development to keep it in line with social needs and political aims is disappointing in view of the longstanding public and political concerns about the negative impacts of technology in many areas and the desire to mobilize technology for positive objectives such as sustainable development (Smits and Leyten 1991 ). Apparently, the challenge is indeed very difficult to meet.
