  1. Renewable Energy

  2. Renewable Sources of Energy • Hydro • Solar • Wind • Geothermal • Biomass • Tidal

  3. How much renewable energy does Canada use? Check out the Green pieces of pie.

  4. Flowing water is used to spin a turbine to generate electricity

  5. Diga del Cingino dam in ItalyLook closer... See spots on the dam wall?  What are they?

  6. European Ibex like to eat the moss and lichen. They also lick the salt off the dam wall.

  7. Hydro Power in Canada • 581 large hydropower dams • Quebec has the largest number (32%), followed by Ontario and BC

  8. Niagara Falls RMR Rick at the Niagara Falls tunnel project: Big Becky completed 2013 http://www.youtube.com/watch?v=y1tT7upP6JE

  9. Sainte-Marguerite rockfill dam, Quebec Rises 171 metres in the air and is the highest dam of its kind in Québec.

  10. The stability of this concrete dam is ensured by the structure's weight.

  11. Daniel Johnson Dam, Quebec Multiple-arch-and-buttress dam Inaugurated in 1969, it was named after Québec's Premier. Its reservoir is four times the size of the Island of Montréal, making it the 5th largest reservoir in the world

  12. Hydroelectricity energy: Pros • Capable of generating large amounts of power • Reliable; water flowing means electricity is produced • No emissions

  13. Hydroelectricity energy Cons: • Flooding for reservoir can disrupt local ecosystems • Cannot be built everywhere • Sites are often distant from where energy is used/needed RMR Rick builds power lines http://www.youtube.com/watch?v=9-B3D3nvUho

  14. Hydroelectricity • Video - Three Gorges Dam • Edward Burtynsky “Three Gorges Talk” • http://www.bbc.co.uk/news/world-asia-pacific-13460536 • http://videos.howstuffworks.com/discovery/7143-china-three-gorges-dam-video.htm 2008

  15. Whitehorse Hydroelectric Station, Yukon River

  16. Salmon Fish Ladder

  18. Humans have harnessed wind power for thousands of years, using sails to propel ships and windmills to pump water. Only in the past 30 years has wind been used to generate large utility-scale electricity.

  19. Windmills in Netherlands

  20. WIND • Energy of blowing wind spins a turbine to generate electrical energy Kingston

  21. Installed Wind Energy http://www.canwea.ca/farms/wind-farms_e.php

  22. 1994 Pincher Creek AlbertaCanada’s First commercial wind farm

  23. Grouse Mountain, Vancouver: world’s first and only wind turbine that allows you to stand in a clear glass viewPOD at the top of the tower, three metres from its massive, rotating blades Video: http://www.grousemountain.com/eye-of-the-wind/video

  24. WIND Pros: • No emissions or waste • Windy areas have consistently strong winds • No disruption to ecosystems.

  25. Wolfe Island Near Kingston, Lake Ontario (86 turbines) Wind Turbines Cons: • Requires consistently fast winds to generate electricity • NIMBY: unsightly and noisy

  26. Main sound comes from the aerodynamic swoosh of the blades passing the tower. http://www.canwea.ca/wind-energy/myths_e.php

  27. Solar Energy • Photovoltaic (PV) cells convert sunlight directly into electricity. • sunlight strikes the panel creating an electrical current Solar Energy Explained http://www.aboriginalenergy.ca/solarpopup.html RMR Rick installs Solar Panels Oshawa http://www.youtube.com/watch?v=mmI2BjOO9gg

  28. Solar Map of Canada The 13 PV hotspots in each province and territory in terms of yearly PV potential for south-facing PV panels with latitude tilt.

  29. Solar Energy: Advantages • Simple to operate, no moving parts to fix • Usually reliable (the sun rises each day) • Zero emissions or pollution • No noise Animation: http://www.odec.ca/projects/2006/wong6j2/solar.html

  30. Solar energy: Disadvantages • Solar panels are expensive. • Inefficient in low sun and cloudy conditions • Large surface areas are required to generate useful amounts of energy

  31. Earth's natural heat used to power turbines and generate electricity • Underground steam and hot springs Geothermal

  32. GEOTHERMAL ENERGY Pros: • Renewable, Earth’s heat is consistent • Simple technology Cons: • Can be expensive to drill depending on bedrock

  33. Biomass • Organic material that can be burned to generated renewable power • Examples include wood by-products, municipal waste and livestock manure Biomass Explained: http://www.aboriginalenergy.ca/biomasspopup.html

  34. Biomass Pros: • Renewable sources of waste products (from agriculture, forestry and food processing). • Technology exists at coal/fossil fuel power plants Cons: • Burning causes some polluting gases, smells

  35. Tidal Energy The energy of moving sea waves spins turbines to generate power. Pro: • Renewable • Predictable patterns of tides and waves • No pollution CBC 2009

  36. Tidal Energy Cons: • Expensive • Equipment must be able to withstand salt water & sand • Underwater turbines can kill fish See Animation: http://www.odec.ca/projects/2006/wong6j2/tidal.html

  37. Tidal Power Potential http://www.energybc.ca/images/profiles/tidal/canadatidal.png

  40. Pros of Renewable Energy Sources • The word 'renewable', says it all. • Clean source of energy as they do not involve the combustion or burning of fossil fuels or other substances • Plentiful and are available all over the world • Low maintenance costs • Non-perishable energy sources

  41. Cons of Renewable Energy Sources • Problems with reliability and consistency • Initial investment or setup cost is significantly high • Poor global acceptance of renewable energy on a mass scale
