According to the International Hydropower Association, Canada is the fourth largest producer of hydroelectricity in the world in 2021 after the United States, Brazil, and China. [1] In 2019, Canada produced 632.2 TWh of electricity with 60% of energy coming from Hydroelectric and Tidal Energy Sources). [2]
Overall, hydroelectric power can be far less expensive than electricity generated from fossil fuels or nuclear energy, and areas with abundant hydroelectric power attract industry. In Canada it's estimated there are 160,000 megawatts of undeveloped hydro potential.
Switching to these energy sources requires that end uses, such as transport and heating, be electrified for the world's energy systems to be sustainable. In the U.S. and Canada the use of heat pumps (HP) is economic if powered with solar photovoltaic (PV) devices to offset propane heating in rural areas [24] and natural gas heating in cities. [25]

The U.S. and Canada said Thursday they have agreed to update a six-decade-old treaty that governs the use of one of North America’s largest rivers, the Columbia, with provisions that officials ...
However many run-of-the-river hydro power plants are micro hydro or pico hydro plants. Much hydropower is flexible, thus complementing wind and solar, as it not intermittent. [92] In 2021, the world renewable hydropower capacity was 1,360 GW. [73] Only a third of the world's estimated hydroelectric potential of 14,000 TWh/year has been developed.
Hydropower is now used principally for hydroelectric power generation, and is also applied as one half of an energy storage system known as pumped-storage hydroelectricity. Hydropower is an attractive alternative to fossil fuels as it does not directly produce carbon dioxide or other atmospheric pollutants and it provides a relatively ...
Hydropower is a flexible source of electricity since stations can be ramped up and down very quickly to adapt to changing energy demands. [31] Hydro turbines have a start-up time of the order of a few minutes. [37] Although battery power is quicker its capacity is tiny compared to hydro. [2]
