HYDRO DAMS
Hydro Dams �Energy is produced by flowing water �The more water there is and the faster it flows the more energy is produced

Hydro Production � 1920 -1950 � 90% of Canada’s power came from hydro dams � 2010 � 59% of Canada’s power comes from hydro dams �The rest comes from � Coal � Nuclear Power � Natural Gas � Renewable Energy
Generating Power �Manitoba generates 8% of Canada’s electricity �Quebec- 50% �BC- 16% �Ontario 12% �All others are less than 1%
Exporting Power to the U. S. A �Quebec and Manitoba are the largest exporters of power to the United states �Quebec – 16. 4 terawatt hours (TWh) �$1. 13 billion �Manitoba – 8. 6 terawatt hours (TWh) � $321 million
Pros �Hydro dams last a long time and can create large amounts of power over their life span �Low operating costs �Clean, efficient, reliable �No direct greenhouse gases
Cons �Cause flooding �Displacement of people �Destruction of habitats � 400, 000 dams square kms worldwide has been lost due to hydro �Animal migration �Water acts as a “heat sink” �Create methane �Methylmurcury accumulation
