1. Conventional Energy: Renewable Resource
What is Conventional Energy?

2. Energy Canada is the largest per capita user of energy because:
We live in a northern climate – heat
Small population with a large land mass – transportation needs
Advanced industrial economy
Energy is cheap = waste

3. Energy can be divided into 2 categories
1. Conventional Energy
Water
Coal
Oil
Natural gas

4. 2. Alternative Energy Sources
Solar
Wind
Biomass

6. Sources of Energy

7. Conventional Energy Energy that is commonly used as sources of: Heat
Light
Power

8. What is Renewable Energy?
An energy supply that can REPRODUCE itself fairly quickly (can make more)
Example: wood
It grows relatively quickly (especially bamboo) and is used for heat, light and power

9. Hydroelectric Power Power that is created by falling water.
Example: Niagara Falls
About 60% of all of Canada’s electricity comes from hydroelectric power.

10. Two Benefits of Hydroelectric Power are…
1. It is cheap because no fuel is needed
2. no burning fuel means no air pollution

11. Two Problems with Hydroelectric power are…
1. it is very expensive to build and repair
2. often must be built far from
energy customers

12. Conventional Energy: Non-Renewable Sources
What is Non-Renewable Energy?
Energy that CANNOT reproduce itself.
(once it’s gone, it’s gone forever!)

13. Examples are…
Minerals
Uranium
Fossil fuels

14. Nuclear Power Plant
Inside a nuclear power plant, atomic particles (neutrons) are fired at uranium atoms.
As the uranium atoms shatter apart, they release heat energy and radioactivity.
The heat energy is then converted to electricity inside the power plant.

15. Nuclear Power Plant
This process uses up the uranium which is a non-renewable resource
Nuclear reactors produce about 15% of Canada’s electricity

16. Two Benefits of Nuclear Power Plants are…
1. They are cheap to run – especially in Canada because we have a lot of uranium
2. Nothing is burned, so there is no air pollution

17. Two Problems with Nuclear Power Plants are…
1. They are very expensive to build and maintain
2. If the reactor fails, radioactivity can kill plant workers and members of the public

18. What are Fossil Fuels?
Fossil fuels contain the stored CARBON of things that were once ALIVE
Examples are: coal, oil and natural gas

19. What are Fossil Fuels…
About 25% of Canada’s electricity comes from burning non-renewable fossil fuels
They power almost all our modes of transportation
They heat and cool most of our homes, businesses and industries (and schools!)

20. Benefits of Fossil Fuels
Easily Available
Produces a large amount of energy

21. Problems with Fossil Fuel
Environmental Damage causing climate change
Rising gas prices/over production
Largest contributor to Global Warming
Need huge amount of reserves due to human dependency

22. Thermal Electric Power
Energy created by heat and/or steam
This is the cheapest form of the conventional energy systems

23. How does it work??
Coal is burned in furnaces to provide enough heat to boil water and create steam.
The steam spins turbines that produce electricity

24. One Benefit of Thermal Electric Power is…
It is the least expensive type of conventional energy

25. One Problem of Thermal Electric Power is…
Carbon from burned fossil fuels harms the atmosphere causing…
Air pollution
Climate change
Acid rain

26. Other forms of energy…
