1. ENERGY SUSTAINABILITY
RENEWABLE AND ALTERNATIVE ENERGY SOURCES

2. THE PROBLEM WITH FOSSIL FUELS
Canada can’t continue to rely on burning fossil fuels for energy.
Why?
Non-renewable and emits pollution that causes climate change
Solution?
Canada needs to use more renewable energy sources.

3. SOLAR ENERGY
We can use panels that absorb the sun’s energy and other technology to convert it into electricity.

4. SOLAR ENERGY ADVANTAGES
Reliable, consistent supply
Photovoltaic panels (solar panels) are becoming more efficient and less expensive
Connects right into existing power grid
Can be used locally

5. SOLAR ENERGY DISADVANTAGES
Sun does not shine all the time
Not equally available across Canada
Needs many collectors to generate enough power
Where would we find the best places in Canada for solar power?

6. WIND ENERGY
Wind turbines can be used to harness the power of the wind

7. WIND ENERGY ADVANTAGES
The price of wind generators is coming down
Connects right to the existing power grid
Can be used locally

8. WIND ENERGY DISADVANTAGES
The wind does not blow all the time
Wind is not uniformly available across Canada
Need many turbines to generate enough power
Where can we find the most wind in Canada?

9. TIDAL ENERGY
Generating stations can harness the power of the tides

10. TIDAL ENERGY ADVANTAGES
Reliable, consistent supply of energy
Improved designs of generators are making more sites possible

11. TIDAL ENERGY DISADVANTAGES
Very few suitable sites
Generating stations are expensive to build
Environmental impact of generating stations (hurts ecosystem)
Where would they work best in Canada?

12. HYDROELECTRIC ENERGY
Massive dams can be built to harness the power of water flowing through rivers

13. HYDROELECTRIC ENERGY ADVANTAGES
We could potentially generate twice as much as we do now
Reliable, consistent source of energy
Highly efficient

14. HYDROELECTRIC ENERGY DISADVANTAGES
Significant environmental impacts when building generating stations
Depends on extensive power grids
Tends to be huge projects rather than small local ones
Where are they in Canada?

15. OTHER ALTERNATIVE ENERGY SOURCES
Geothermal
Nuclear
Kinetic
Methane
Biofuels
