Everyone could stand to be more energy efficient. Whether your goal is to reduce your carbon footprint, save money on utilities, or both, you’ll be glad for this guide from Charles Window. We find that many homeowners either think that they’re doing all they can or that making seemingly small changes won’t make a big difference. Read on to learn the truth.

1. Make sure your windows and doors aren’t reducing your home’s energy efficiency

One of the biggest ways you can increase the energy efficiency in your home is to look at your windows and doors. For example, if you have single-pane windows then replacing them with insulated glass units (otherwise known as IGUs) can save you quite a bit on heating and cooling costs. Even if you have newer, double- or triple-pane windows, you can look for gaps in your windows and seal them. If your doors let in air from below, consider having new doors installed or add a door sweep to prevent losing conditioned air.

As you consider this option, it’s important to know just how impactful it can be. Experts say that if you make no changes except to replace your single-pane windows with newer, more insulated windows, you can save over $450 a year.

2. Let your appliances help you improve your home’s energy efficiency

If you’re using ancient appliances then upgrading to ENERGY STAR appliances can make a huge impact. When you use the dishwasher or your washing machine, make sure you’re only running full loads. We also recommend unplugging small appliances when they’re not in use, such as your toaster, microwave, blender, coffee maker, etc.

Note that replacing just your old refrigerator with an ENERGY STAR refrigerator can save you around $50 per year, and replacing an older dishwasher can save you another $40 per year.

3. Make minor changes to your water heater and see big savings

Some seemingly minor changes to your water heater can result in big savings. First, set your water heater temperature at 120 degrees. Next, buy an insulated water heater blanket to cover your water heater. This helps keep the heat in and reduces the cost of heating the water in the first place. Finally, insulate your hot water pipes.

Studies show that these savings can add up: For each ten degrees you’re able to reduce the hot water heater temp, you can save been 3% and 5% on the costs of water heating.
