Hydropower

By District 5, Period 5 Division (Randy, Armaan and Anthony)

What is Hydropower?

Power derived from falling or running water, since ancient times it has used for irrigation as well as powering watermills, sawmills and textile mills. In modern times, it is mainly used to produce electricity.

How is modern hydropower produced?

A dam placed on a river holds back water in what's called the reservoir. Due to gravity, water flows into the intake and through the penstock until it reaches the turbine. The water passes the turbine and reaches the outflow river. The water moves the turbine, which is connected to the generator by a shaft, producing power. The electricity from the generator are transported by power lines to where it is needed.

Hydropower Statistics

Hydropower produces about 600 TWh of electricity in the United States and Canada annually

It produces 58.4% of all electricity produced in Canada

Over 30 terrawatt-hours (TWh) of electricity in Ontario annually, it provides 23% of the province's energy needs

The Benefits of Hydroelectricity

Cost efficiency

Hydropower is produced for an average of 0.85 cents per kilowatt-hour (kwh) in the US.

About 50% the cost of nuclear, 40% the cost of fossil fuel, and 25% the cost of using natural gas

Power efficiency

Hydropower has an efficiency of 80 to 90%, about 30% greater than any other energy source.

Keeps Air Clean

Hydropower produces the least amount of greenhouse gas emissions of coal, natural gas, biomass, solar, wind and nuclear power. At it's highest it can produce 48 grams of CO2 to produce one kWh of energy, 25 times less CO2 than coal power plants which produces 1182 grams per one kWh.

It's Energy can be Kept in Reserve

The water in the reservoir can be saved until it is needed for use as energy. Water in the reservoir can be reserved at night and greater flow can be allowed during the day due to increased power consumption.
