FLOW RESOURCES

1. FLOW RESOURCES RUNNING WATER TIDES

2. FLOW • You have learned that flow resources are energy supplies such as moving water, the wind, and the sun’s rays. • Earlier societies discovered how to create working energy by using windmills and big wheels turned falling water. • Now we have the technology to build powerful hydroelectric power dams and collect solar radiation.

3. TIDE • Canada even produces electricity by using the 10 metre rise and fall of the Bay of Fundy tides in Nova Scotia.

4. Tidal Power

5. RUNNING WATER • Canada is a powerhouse, producing more electricity from running water than any other country. Only Brazil, USA, and China come close. These 4 nations share certain characteristics that combine to favour hydroelectric power production • Very large areas of land • Several large rivers flowing toward ocean coasts • Rugged areas suitable for constructing dams across rivers • Highly industrial or rapidly industrializing

6. Hydroelectric Dam

7. HYDRO DAMS – HOW THEY WORK

8. HYDROELECTIC DAM • Moving water racing over rapids or out of a narrow channel provides mechanical power to turn many spinning wheels called turbines. • In turn, the turbines rotate generators – mini power plants that change mechanical power into electrical energy. • Finally, electrical transformers are used to boost power voltages to push them great distances through high voltage wires.
