- Hydropower is a clean energy
Hydropower is one of the best production chains. Indeed, analysis of the full life cycle shows that hydropower emits very little greenhouse gas emissions (GHG) .
Thus a hydroelectric plant with reservoir located in northern area emits 10 grams of carbon dioxide (CO 2 ) per kilowatt-hour. This is the same amount as its wind equivalent to four times less than its equivalent with solar photovoltaic panels. A hydroelectric power plant produces 100 times less greenhouse gases than coal plant.
The electricity sector is also accounted for only 0.6% of GHG emissions in Quebec in 2009. It is a remarkable performance, due to our use of hydropower.
In Quebec, transport is responsible for 44% of GHG emissions. The electricity will eventually replace a significant portion of the oil used on the roads. The electrification of ground transportation will thus have a significant impact on the environmental performance of Quebec and neighboring markets.
Its small contribution to GHG makes hydropower a great way to fight against climate change while promotingsustainable development .

- Hydroelectricity is a renewable energy source
In 2004, 154 countries have recognized hydropower as a source of energy renewable . Because it consists of water annual rainfall over a large area, the source of hydropower is inexhaustible.
Indeed, water follows what is called the hydrologic cycle, describedbelow.
By warming oceans, lakes and rivers, the sun evaporates water. Water vapor amount in the atmosphere where they condense and turn into clouds. When the weight of water droplets or ice crystals forming clouds becomes too high, the droplets and crystals fall to the ground as rain or snow. Thus, the water returns to the earth, back to the lakes, rivers and oceans, and the cycle repeats.
- Hydropower has a higher energy efficiency
The loss of energy accompanying the transformation of water movement into electricity (ie hydropower) is minimal. The transformation of fossil fuels, such as oil, natural gas or coal, generally leads to significant losses in the form of waste heat. When burning coal, for example, two-thirds of the energy is lost as the water that drives the turbines of a hydroelectric plant is used to the last drop.
- Quebec is full of water
Quebec is one of the most water-rich regions of the world. There are more than 130,000 rivers and lakes 1,000,000. Over 40% of Canada's water resources are in Quebec. Its surface water bodies (natural lakes and reservoirs) cover about 12% of its territory.
