Energy conservation programs in Ontario are now delivered through the Independent Electricity System Operatior (IESO).


  • Use your dishwasher and dryer early in the morning, in the evening or on weekends when electricity rates are lower.
  • Only run full loads in the dishwasher.
  • Use an outdoor clothesline during summer to save electricity.
  • When buying a new washing machine, look for an ENERGY STAR qualified front-load model to reduce water use by almost 45% and energy use by about 65%.
  • Do laundry only when you have a full load.
  • Refrigerators are one of the biggest electricity users in the home, so it pays to consider an ENERGY STAR qualified model.
  • The ENERGY STAR symbol on a new fridge means:

    • It is at least 15% more energy-efficient than the minimum standards set federally.
    • Uses half as much electricity as a fridge that's 10 years old.

Cooling and Heating Your Home

  • In the summer, set your central air conditioner (CAC) for 25°C when you are home, and 28°C when away. Or, if you can, turn it off.
  • Service your central air system annually.
  • Clean or replace the furnace filter once a month to keep it operating efficiently. A clogged filter impedes furnace performance.
  • Have a licensed HVAC (heating, ventilation, air conditioning) professional service your furnace yearly to ensure it is operating at maximum efficiency.

Phantom Power

  • Electronic devices left plugged in, even when turned off, still draw power. It's called phantom power or standby power, and it's costing you money. Plug electronics into a power bar with a timer or auto shut-off and make sure they are off during periods of inactivity.
  • By reducing this unnecessary power use, you could help save up to 20% on your electricity use.

Seasonal Tips

  • Check for gaps. Weather-strip around doors, fireplace dampers, attic hatches and air conditioners. Reducing drafts, can save up to 30% a year on heating costs.
  • Choose energy-efficient Light Emitting Diodes (LEDs) when you need to replace light bulbs.
