Hydro Hawkesbury offers some solutions to conserve energy.

Heating & cooling

  • Install a programmable thermostat to manage the amount of energy used to heat and cool your home, especially when you are not home and at night while you are sleeping.
  • Caulk, seal and weather-strip windows and install a seal sweep on doors to keep the heat in during the winter and the cool in during the summer.
  • If windows are not airtight, use plastic window film during the winter.
  • Set ceiling fans to force air down in summer and up in winter.
  • Keep lamps, televisions, and other heat-producing appliances away from thermostats – they make air conditioners work overtime.
  • Locate air conditioning units on north side of home or in shaded area if possible.
  • Keep doors and windows closed when heat or air conditioning is on.
  • Clear away anything blocking heating and cooling vents.
  • Replace or clean furnace filters regularly.
  • Consider an Electric Thermal Storage unit rather than electric space heaters.

Hot water tanks

  • Wrap an electric hot water tank with an insulating blanket, especially when located in an unheated area.
  • Insulate water pipes leaving the hot water tank.
  • Consider replacing an old electric hot water heater with a new Tankless Water Heater, which heats water only on-demand.


  • Use ENERGY STAR qualified compact fluorescent light (CFL) bulbs - they use up to 75% less electricity than regular incandescent bulbs.
  • Use correct CFL bulb for the application (dimmer switches, recessed lighting, tri-lights, outdoor fixtures, etc).
  • Use LED holiday light strings instead of incandescent light strings.
  • Dust bulbs regularly. A clean bulb is brighter.
  • Turn lights off when room is not in use.
  • Use timers and motion sensors for indoor and outdoor lighting so lights come on only when needed.
  • Consider task lighting where needed instead of lighting an entire room.


  • Use a clothesline or clothes rack for indoor and outdoor drying.
  • Operate dryer with full loads.
  • Use dryer’s automatic cycle to prevent over-drying.
  • Clean dryer lint trap after every load and make sure the vent is never blocked.
  • Time washing/drying cycles so dryer drum stays warm when changing loads.
  • Select correct water level for load size when washing.
  • Use cold water wash and detergent whenever possible.
  • Rinse with cold water.
  • When purchasing a new washer, consider a front-load model – they’re more energy efficient and use less water.


  • Install low-flow showerheads and low-flow toilets to reduce water consumption.
  • Take showers instead of baths – try to keep showers less than 10 minutes.
  • Repair or replace leaky faucets and toilets.


Fridges and Freezers

  • Ideal fridge temperature is 1 to 4°C, ideal freezer temperature is –15 to –18°C.
  • Try to avoid standing with the fridge door open.
  • Do you really need that second older fridge?
  • Vacuum coils on back and/or under fridge regularly.
  • Make sure there is enough air space between fridge coils and wall.
  • Use small appliances like microwave, toaster oven or barbeque instead of oven when possible.
  • Turn on oven light and look through glass window instead of opening door to check food.
  • Use electric kettle for boiling water instead of a pot on the stove and boil only as much water as needed.
  • When purchasing an electric kettle, select one with a water level indicator and an automatic shut-off feature.
  • Use pots the same size as the element.
  • Use covers/lids on pots.
  • Keep trays under stove elements clean to reflect heat up.


  • Use cold water to rinse dishes.
  • Only run dishwasher when full.
  • Use delayed start or timer feature on newer models of dishwashers to run during off-peak hours.
  • Use dishwasher’s shortest (econo) cycle.
  • Air dry rather than use dishwasher’s heat dry feature.
  • Use a thermal cover on your pool or hot tub to trap heat inside when not in use.

Around the house

  • Use a power bar for all computers, entertainment and peripheral devices to shut down and power off all equipment when not in use.
  • Plant leafy trees on south side of home and evergreen trees on north side – for shade in summer and wind protection in winter.
  • Use the most energy efficient type of lawn mower.
  • Install solar-powered LED garden landscape lights to increase outdoor visibility.
  • Use motion sensors on outdoor lighting that does not need to always be on.
  • Top up existing insulation or add to a non-insulated attic – it could reduce annual energy costs by 5 – 30%!
