A truly sustainable energy resource
While there are a number of ways to generate power from moving water, in all cases the energy is “renewable” (“derived from a natural process that is replenished at a rate that is equal to or faster than the rate at which they are consumed”). As water is not consumed, depleted or wasted in the process, and as the greenhouse gas emissions from water power are minimal over a facility’s lifetime, waterpower is an extremely sustainable energy resource.
The large majority of hydropower generated in Canada comes from run-of-river or reservoir generating stations.
In Canada, much of our hydroelectricity is produced when water is stored in a reservoir behind a dam. The “potential energy” of this water is converted to kinetic energy when it flows upon release from the reservoir into the penstock. “Pumped storage” is another type of hydropower which also stores water in a reservoir. At pumped storage facilities, water is pumped up to an elevated reservoir for storage. When electricity generation is required, the water is released into the penstock.
“Run-of-river” hydropower is also common where water from a river simply flows directly into the penstock. “Hydrokinetic” is a less common approach in which a turbine is placed in a river bed or tidal area to directly capture the energy in the water flow.
As the only clean, renewable and abundant source of baseload dispatchable electricity, waterpower truly is Canada’s natural advantage

- 0 air pollutants in operation, ultra low life-cycle greenhouse gas emissions.
- The ONLY abundant form of renewable, flexible baseload electricity generation with long-duration energy storage.
- 100+ years of facility life.
- Converts over 90% of available renewable energy from water into electricity. Hydropower is the most efficient source of electrical energy. By comparison, the best fossil fuel power plants operate at approximately 60% efficiency.
Despite being one of the largest hydropower producer in the world, Canada could still more than double its waterpower installed capacity. And even more amazing is the fact that this potential exists from coast-to-coast, in virtually every province and territory!
