1. Results of the questionnaire on environmental constraints of wind energy use Chris Coppens, Hans Elzenga MNP The Netherlands EEA expert meeting Copenhagen 9 November 2006

2. Chris Coppens, Results questionnaire 2 /7 EEA Study Focus: EU-25; preferable NUTS-2 Focus on land availability & technology development How:GIS approach Use survey for data environmental constraints Goal: Wind power density map Environmental constraint supply curve per nuts region Various scenarios up to 2030

3. Chris Coppens, Results questionnaire 3 /7 Questionnaire When: Early June 2006. Who: NFPs, European Commission, other experts. Result:43 questionnaires 24 responses 14 alternative constraints (table p 14) 8 comments on method

4. Chris Coppens, Results questionnaire 4 /7 Environmental constraints General Geographical coverage 4 MW No unambiguous values: –Response too low –Range too large –Remarks on the methodology

5. Chris Coppens, Results questionnaire 5 /7 Environmental constraints (2) Details 2/3 agreed: proposed values “ok”. Alternative values: country or EU-25. High-pot: only 1/2 agreed, wide range. Non-protected  vs. Natura 

6. Chris Coppens, Results questionnaire 6 /7 Regulations and research Many respondents provided info on national regulations. Additional information on WE, constraints etc Analyse and report in later stage Language

7. Chris Coppens, Results questionnaire 7 /7 It must be concluded that the results of the questionnaire did not supply enough information to derive unambigious values for wind energy potentials for the land/sea use categories that we presented: for that purpose the number of respondents that agreed with the values we proposed is too low and the range in alternative values too large. Also we can not ignore the critical remarks we received on the methodology that we used. The answers to the questionnaire can however serve as valuable additional information. It is common practise to use Environmental Impact Assessments (EIA) to determine the suitability of sites for wind farms. However, the EIA’s approach cannot be used to estimate the wind energy potential for the long term at the European scale.

8. Chris Coppens, Results questionnaire 8 /7 Recommendations Add “bottom-up”approach Don’t stick to one baseline to derive an evironmental compatible potentialon Follow up Hans Eerens: proposed approach Monique Hoogwijk: Technical information calculation methodology
