  9. 9

    Reduce the amount of laundry you wash – clothes don't have to be washed every time you wear them, as long as they pass inspection! This can help you save money in the long run and keep your clothes looking newer longer.

Kitchen Appliances

  1. 10

    Preheat ovens only for a minimum amount of time. Preheating is only really necessary for baking.

    to do!?
  2. 11

    Instead of using your oven to reheat food, use a toaster or microwave oven to save energy.

    toaster over
  3. 12

    Use pots and pans that match the size of the stovetop’s heating element.

  4. 13

    Keep your freezer at -18°C. Setting your freezer colder than that will use more electricity.

  5. 14

    Refrigerators are one of the biggest electricity users in the home, so it pays to consider an ENERGY STAR qualified model.

    Energy Star logo
  6. 15

    Keep the back and underneath of refrigerators and freezers dust-free with regular vacuuming.

  7. 16

    Maintain a space of 5 cm around your fridge and freezer so heat can circulate away from the compressor and condensing coil.

  8. 17

    Ensure that refrigerator and freezer door seals are tight and secure.

  9. 18

    When buying a new freezer, look for a smaller chest freezer or an ENERGY STAR qualified model. Front loading models use more energy.

    Add exterior and interior insulation to your basement.

  2. 40

    Insulate your home thoroughly to keep it cooler in summer and warmer in winter. Install a minimum of 25 cm (10") of insulation in your attic.

  3. 41

    Seal areas around plumbing stacks, ceiling fans and light fixtures where they join the floor or ceiling to prevent drafts.

  4. 42

    Foam gaskets will insulate electrical outlets and lights switches on your home’s exterior facing walls.

  5. 43

    Ensure attic insulation doesn’t block air movement.

  6. 44

    chaulking gun Air leaks account for the largest amount of heat loss from your home! Seal leaks around light fixtures, plumbing stacks, windows, exterior doors, attic hatches, pipe and wire entrances, wood-burning fireplaces, electrical outlets, and ceiling fans.

  7. 45

    Open soffit, roof, and gable vents to let in air and control moisture, thereby preventing damage to insulation and wood (daylight should be seen through vents).

Programmable Thermostats

  4. 48

    In the winter set the thermostat to 20°C when you are home and, 18°C overnight or when away.

  5. 49

    Install the thermostat on an interior wall where there are no vents or drafts.

  6. Remember, avoid having your furnace thermostat in a room with a fireplace.

Water Pipes

  1. 50

    For an electrically-heated hot water tank, install pipe insulation around as much of the incoming cold water pipe and the outgoing copper hot water pipe as you can conveniently access.


    Gas-heated hot water tanks should only be insulated by a professional

    Never insulate plastic hot water tank pipes as they can overheat.

Home Offices

Computers and Office Equipment

  1. 51

    Plug the following electronics into a power bar with a timer or auto-shut off and make sure they are off during periods of inactivity:

    • televisions and home theatre systems
    • computer, computer monitor, printer, scanner
    • rechargeable devices (MP3 players,
      cell phones, battery chargers, etc.)
    • game consoles
    • and more…
    power bar with built-in timer
  2. 52

    Electronic devices left plugged in, even when turned off, still draw power. That’s called phantom power or standby power, and it’s costing you money. By reducing this unnecessary power use, you could help save up to 15% of your electricity use.

  3. 53

    Make sure any computer you purchase has an automatic power-down function that will automatically switch the monitor into sleep mode or, preferably, deep sleep mode after a set period of inactivity. (A mandatory feature for ENERGY STAR models.)

  4. 54

    Shut your computer down when not in use to save electricity and reduce wear on your system.

  5. 55

    When replacing your computer, look for an ENERGY STAR qualified model.

  6. Laptops use less energy than desktop models.

  7. Your computer’s screen-saver doesn’t save energy!


ENERGY STAR qualified LEDs and Colour

LEDs are available in a wide variety of shades of white light, ranging from yellowish to white to bluish white light, which allows you to customize the mood of your space.

Many LEDs come in “warm” colours to match the yellowish light of incandescent bulbs, but you can also choose “cooler” colours with whiter or bluer light. Light colour is measured on a temperature scale referred to as Kelvin (K). Lower Kelvin numbers mean the light appears more yellow; higher Kelvin numbers mean the light is whiter or bluer.

  1. Kelvin light temperature samples
  2. 56

    For a whiter light, look for bulbs marked 3500–4100 K.

  3. Bulbs that measure at greater than 3500 K will enhance cooler colours (blue, green, violet) in your home.

  4. 57

    For bluer white light, look for bulbs marked 5000–6500 K.

Exterior Lighting

  1. 58

    Small children can learn about the source of Kingston tap water (Lake Ontario) when you encourage them to “save some water for the fishies”.

  2. 82

    Fix any leaky taps!

    A single faucet with a constant drip can waste up to 182 litres of water per week. If it’s a hot water tap that’s leaking, you’re sending your energy dollars down the drain.

  3. faucet dripping money
  4. 83

    Rinse dishes in a tub of clean water or a second sink, instead of under hot running water.

    If you have an ENERGY STAR dishwasher, use it instead of hand washing to save even more water!

  5. 84

    Always turn the faucet off when it is not needed and save 10–40 litres per day.

  6. 85

    Install a flow restrictor or an aerator save up to 20 litres per day.

  7. Faucets can account for 12% of indoor water use.
