  1. Renewable Energy: A Solution to Pollution Tim Weis, P.Eng., Ph.D. Alberta Regional Director timweis@canwea.ca 780.667.6519 May 1, 2014

  2. About Tim • Alberta Regional Director • Professional Engineer • M.Sc. research on ice adhesion to wind turbine blades in subarctic • Ph.D. research on off-grid renewable energy

  3. Climate change “….could be the biggest global health threat of the 21st century” The Lancet

  4. Canada’s greenhouse gas emissions Source: Environment Canada, National GHG Inventory Report 2009

  5. Air pollutants from electricity sector

  6. How do we compare?

  7. PM formation - Edmonton Source: Clean Air Strategic Alliance. Fine particulate matter in the capital region (2010)

  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)

  9. So why wind? • Efficiency • Electrify • Renewables • Heat + Power 9

  10. So why wind?

  11. Wind is a cost effective option New Electricity Supply Costs in Alberta Source: Solas Energy Consulting

  12. Wind can be developed at high levels

  13. Wind can be developed quickly

  14. Integrating Renewables (NREL study) Net: CO2 ↓ 31.5% Net: NOx ↓ 19.5% Net: SO2 ↓ 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

  17. Closer to home: Ontario

  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
