  1. Jacob Ladenburga MetteTermassenb BeritHaslerb Jens-Olav Dahlgaarda Assessing acceptability of two onshore wind power development schemes: A test of viewshed effects and the cumulative effects of wind turbines a Danish Institute of Governmental Research, Nyropsgade 37, 1602 Copenhagen V, Denmark bDepartment of Environmental Science, University of Aarhus EWEA 2012 Copenhagen

  2. Whatspatial relations drives acceptance of wind power? Several studies have analysed the relation between attitude and distance to wind turbines (Ladenburg and Møller, RSER, 2011) Attitude mightbe driven by other elements that distance. Seingone turbine daily 1 km from the residencemightbedifferent from seeing 15 turbines 2 km from residence Few studies have estimated the cumulativeeffectsonacceptance (Ladenburg & Dahlgaard AE)

  3. The survey 1072-1076 sampled from web panel in 2005 Attitudes towards different themes related to wind power development High income house holds and respondents with longer educations overrepresented compared to the Danish population.

  4. Cumulativeeffectsmeasures • Statednumber of wind turbines seendaily • 0-5 • 6-10 • 11-20 • >20 • Don’trecall

  5. Wind power scenarios General developmentscheme Increase the number of on-land turbines (particular of interest in newerwind turbine nations) Replacement of smaller and older turbines with new and largerones (particular of interest in olderwind turbine nations)

  6. Results I Older respondents are more negative – supporting the general age effects found in the literature Mixed educational effects No direct effects from viewshed to onshore or offshore wind turbines

  7. Results II: (logit model) Standard errors in []. +p < 0.10, *p < 0.05, **p < 0.01, ***p < 0.001 a The variables are jointly significant at a 90% level of confidence. b Max 7 yrs. Elem. Sch. Predicts perfectly, all are positive.

  8. Results: Predictedprobabilities

  9. Conclusion • Cumulative effects seem to be of importance in the planning of future wind power • The cumulative effects appears to be a function of wind turbines densities and viewshed effects • The cumulative effects also seems to be dependent on the type of wind power development schemes
