1. Energy Resources of Canada
Pgs

2. Energy Use
Canadians are among the highest energy consumers in the world. (6th highest)
Our high standard of living (cars, computers, appliances, etc.) contribute to our high energy use.
Do we take our energy for granted?

3. Reasons
We are a HUGE country and our population is spread out (dispersed).
Our climate is cold in the winter and often hot in the summer.
Our lifestyles.

4. Question?????? Is there a limit to Canada’s energy resources?
What changes do you think could be made to make Canadians’ energy resources sustainable?

5. Energy Resources
Is a power source that people can use to do work in order to meet their needs and wants.
Energy resources fall into two main categories: (i) renewable (e.g., wave), and (ii) non-renewable (e.g., nuclear)

6. Canada We are MAJOR producers and consumers of energy resources.
Our energy resources are unevenly distributed.
They contribute to our wealth as a nation.

7. Sources of Energy

8. 1. Coal Is a non-renewable FOSSIL FUEL.
It was formed from the remains of ancient forests and swamps.
As trees and other plants died, leaves and branches fell into the swamps.
Unable to decay in the waters they accumulated to form thick layers of vegetable remains

9. These were buried over millions of years by sediments and the remains of other swamps.
Pressure and chemical changes turned the sediments into sedimentary rocks and the vegetable remains into coal.
Most comes from Alberta.
Not popular as it once was.

10. Advantages:
For many years it was cheap, readily available, and easy to transport
Disadvantages:
Highly polluting
Reserves are getting more expensive to mine
Non-renewable

12. 2. Oil or Petroleum
Oil was formed from the decomposed bodies of plankton buried in the muds of shallow seas.
Over millions of years, these organic liquids were transformed by pressure and chemical reactions into small drops of petroleum.
The oil mostly accumulated into petroleum traps

13. Advantages:
Plentiful
Relatively cheap source of energy
Easy to transport
Disadvantages:
Pollution
Becoming more expensive
“addiction to oil”
nonrenewable

15. 3. Natural Gas
Like oil, natural gas is formed from the remains of plankton that fell to the sea bottom and were covered by fine muds and silts.
These remains were altered over millions of years into gasses.
They accumulated into the same traps that contain the oil.

16. Natural gas was regarded as a useless by product for years, however since the 1950’s it has gained prominence.

17. Advantages:
Cleaner burning than oil. Less pollution
Many known reserves
Disadvantages:
Difficult to transport (pipelines or LNG)
Still create pollution issues. Add to global warming
nonrenewable

19. 4. Hydroelectric
Dams are constructed to raise water levels and create an artificial drop.
The falling water turns turbines, which in turn drive the generators that convert the mechanical energy of moving water into electrical energy.

20. Advantages:
Clean and safe
Abundant in some areas
Disadvantages:
Lack of suitable rivers in many areas
Expensive initial investment
Disruption of wildlife habitats
Destruction of forests and ecosystems

22. 5. Nuclear
The heat source is generated by splitting atoms of radioactive materials, such as uranium-235, in a process called nuclear fission.

23. Advantages:
Originally considered to be low cost. And pollution free.
Disadvantages:
Complex safety and back-up systems needed to guard against break downs in the reactors have made the cost expensive
Overall safety concerns

25. 6. Others
Wind
Solar
Geothermal
