1. Outdoor temperature: different season, different situation

Spring

When days get longer and temperatures are milder, spring is usually right around the corner. In Québec, days can get quite warm but nights can be cool. There are different ways to consume wisely.

Summer

In summer, we try to stay cool in a number of ways, and that can lead to higher electricity costs. For example, if you have a pool or air-conditioning, your consumption will increase. Make wise choices to cut your electricity bills.

Fall

Most Quebecers start heating their homes in the fall and set their thermostats at a comfortable temperature.

Thermostats modulate the output of the heating system to maintain the set temperature. When it’s 15°C outside, the heating system doesn’t have to work too hard and consumption is moderate.

Be winter ready

Winter

In winter, especially during cold snaps, your heating system works at full throttle. If it’s powered by electricity, your consumption will increase.

Heating consumption will vary from one region to the next for the same type of home. For example, heating costs are higher in Rouyn-Noranda because winters there are longer and colder.

In winter, things tend to heat up.

Does your bill show an increase in your electricity use even though you know you haven’t changed your thermostat? That’s perfectly normal. The colder it is in winter, the lower the temperature is inside your home, and the harder your heating system has to work to maintain a comfortable temperature. All that hard work calls for a higher energy consumption.

Electricity consumption when it’s very cold

Postponing the use of major appliances and turning the heat down are concrete steps that help Hydro-Québec optimize electricity distribution throughout the grid when demand is high.

2. Your home’s characteristics

Thermal envelope

Poorly insulated walls, roof spaces and foundations can cause your home to lose up to 40% of its heat. A well-insulated, well-ventilated home is more economical and more comfortable.

Air leaks

Up to 25% of your home’s heat may be escaping. Fortunately, there are inexpensive ways to stop leaks.

How to apply caulking

Doors and windows

You can lose up to 25% of your home’s heat through doors and windows. The number of doors and windows in your home as well as their size, quality (e.g. their energy rating) and exposure can impact the energy consumed for heating.

3. Your habits

By adopting new habits, you can considerably reduce your consumption without spending a penny or sacrificing comfort. Make these little changes when you use the bath, shower, baseboard heaters and cold and hot water.

4. Your appliances and electronics

Certain appliances and electronics consume a lot of energy. Reduce your consumption by using them wisely and in moderation and unplugging them when they are not in operation.

5. Number of occupants

The higher the number of occupants in a household, the greater the electricity consumption. But the number of occupants has little impact on heating. Whether you’re single or in a family of four, you can cut your heating costs by lowering the temperature in your home by 2 to 3°C at night and when you’re away for several hours during the day.
