Insulation: Every form of insulation comes with some R rating. This number indicates the amount of insulation, but are you certain, all exterior walls and ceilings are properly insulated? Doing so, might potentially save a considerable amount of unnecessary energy costs.
Energy efficient appliances: Certain home appliances, especially refrigerators, freezers, and air conditioners, have become far more energy – efficient, in recent years. How old are yours? Look at the rating, and it will indicate how much energy a particular appliance might be using. When I recently replaced my refrigerator, the new one was far more efficient (therefore, cost less to run), than my 15 – year old model. Similarly, today’s oil and gas burners and boilers are far more efficient, than they have ever been!
Water and toilet: Are there any dripping faucets or toilets that continue to run – on? Eliminate the drips, change faucet heads (especially in the shower), and check the efficiency of your toilets.
Lights/ fixtures: Begin by making the effort to turn lights off, when you leave the room! What type of light bulb are you using? Many bulbs today are four, or more times, more efficient (use less energy/ wattage), than older ones. Do a lights and fixtures – review on a regular basis!
