A hydroelectric plant is when a dam produces electricity in an environmentally safe way. It is made using a waterfall or a river usually.

The production of power from water
The water from the dam goes from the reservoir through the intake
Then it goes through the penstock
The water turns the turbine
The turbine activates the generator
The generator puts the electricity into the power lines

Advantages of Hydroelectric Power are	Disadvantages of Hydroelectric Power are
Hydroelectric plants do not create air pollution or any greenhouse gases	It takes really long for it to be built
The use of dams prevents the burning of 22 billion gallons of oil or 120 million tons of coal per year	58% of all dams were planned and built with no consideration of downstream effects
To operate a dam there is few personal needed and little maintenance to be done	Run-of-the-River plants can impact the mobility of fish and other river life.

There are nine Hydroelectric Plants in operation in Canada. There is one in Akolkolex, British Columbia, Belly River Chute, Waterton, St. Mary, and Taylor, all in Alberta. There are four in Ontario located in, Ragged, Moose Rapids, Galetta, and Appleton.
