Which two Canadian provinces are the major producers of hydroelectric power, and what is the significance of this energy source?

• A. Ontario and Manitoba
• B. Alberta and Saskatchewan
• C. Nova Scotia and Newfoundland
• D. Quebec and British Columbia

Answer: (D)

Hydroelectric power uses the energy of flowing water to turn turbines and generate electricity, so provinces with big river systems and suitable terrain can produce a lot of it and do so with low emissions.

In Canada, the two provinces that generate the most hydroelectric power are Quebec and British Columbia. Quebec benefits from vast and powerful river systems and large-scale projects in the James Bay region, which together supply a large share of the province’s electricity. British Columbia also has extensive mountains and many rivers, allowing for many dams and hydro plants that form the backbone of its electricity supply.

The significance of this energy source lies in its renewability and low greenhouse-gas emissions compared with fossil fuels. Hydroelectric power provides a reliable, steady supply of electricity, supports economic activity, and enables electricity exports to other provinces and even the United States. At the same time, these projects require careful consideration of environmental impacts and Indigenous rights, since damming rivers and creating reservoirs can affect ecosystems and communities. Overall, hydroelectric power is a defining feature of Canada’s energy landscape, especially in Quebec and British Columbia.
