8. Costs of air pollution from electricity generation USA - National Research Council at request of 2005 Energy Policy Act – Effects of air pollution on human health, grain crop and timber yields, building materials, recreation, and visibility of outdoor vistas – Average damages: 3.2 ¢ /kWh (2008) Greenstone and Looney: – 3.4 ¢ /kWh for non-climate damage (2010)

12. Wind can be developed at high levels

13. Wind can be developed quickly

14. Integrating Renewables (NREL study) Net: CO 2 ↓ 31.5% Net: NO x ↓ 19.5% Net: SO 2 ↓ 18.5%

15. Integrating renewables

16. Denmark update 52% wind by 2020 100% renewable electricity by 2035 100% renewable energy by 2050 – 171 Parliamentarians voted for 8 against. “The conclusion being it has a cost to make a green transformation, but it also has a cost not to do it. I think this will work out to be the best insurance Denmark has ever (bought).” – Energy Minister Lidegaard

19. Conclusion Renewables can significantly reduce air pollution We have working examples of renewables being deployed quickly and at high levels Challenges remain – policy drives energy decision
