In the recent years several renewable energy sources have been introduced on the electricity market. However, while the renewable energy market is constantly growing, in some cases renewable technologies meet resistance, such as wind energy converters. A lack of social acceptance can be responsible for the delay or even the rejection of an innovative technology. The present research aims to examine the social acceptance of small scale vertical wind turbines as a particular source for renewable electricity. To improve the understanding of the factors influencing the acceptance of wind energy in this paper we integrated previous research on the social acceptance of renewable energy and social psychological models on the attitude – behaviour relation. The participants represent a sample of 120 farmers and house owners. Using survey data and adopting previously established compound measures, regression analyses revealed a remarkable explanatory power for proposed model of social acceptance. The present research is part of an interdisciplinary project in which engineers, economics, industrial designer and psychologists work together to study the technical possibilities as well as the social acceptability of the small scale vertical wind turbines. This project is supported by the Federal Ministry for the Environment, Nature Conservation and Nuclear Safety, Germany.
