Quebecers are among the world’s largest consumers of electricity. This is explained by two main factors. First, a large amount of energy is consumed during the harsh Québec winters, especially for heating. Second, owing to the development of abundant hydropower resources in the late 1970s, most Quebecers turned to electric heating to heat their homes and water. Through this choice, they greatly reduced their dependence on oil products, adopting a minimally polluting energy source. This partly explains Québec’s exemplary performance in terms of GHG emissions.

From now until 2026, electricity consumption will continue to increase, but at an average rate of 0.4% or approximately 0.8 TWh per year, which is faster than the growth observed from 2006 to 2016. To balance supply and demand, we rely primarily on energy efficiency, and on the generation and purchase of clean, renewable energies.

Montréal’s suburbs are growing denser. We offer the public a number of energy efficiency programs to help reduce electricity consumption.
