Renewable and Non-Renewable Energy

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

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

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

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.

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.
