1. Renewable and Non-Renewable Energy

2. A renewable resource is one that can be reused or replaced.
Examples: sun and wind
Solar grid outside of Saskatoon
Centennial Wind Power Facility outside of Swift Current

3. A non-renewable resource is one that cannot be replaced once it is used up.
Examples: coal and oil
Poplar River Coal Mine
Oil Rig outside of Estevan

5. Generating Electrical Energy
Generators: a device that transforms the energy of motion into an electric current
Electric current is created by moving a conducting wire through a magnetic field!
Massive generators are found at the Boundary Dam Power Station near Estevan, SK

6. Example: Hydroelectrical energy
The magnets inside a generator are rotated by a turbine, which is a machine that usually uses the flow of a fluid to turn a shaft.
Example: Hydroelectrical energy
The Coteau Creek Hydroelectric Station near Elbow, SK – the water turns the turbine, which is connected to a generator.

7. Using Heat to Generate Electrical Energy
Thermoelectric generating plants use fossil fuels to heat water to create high-pressure steam.
Fossil Fuels: coal, oil and natural gas – all non-renewable resources.
