11 Ways to Make Your Home Energy Efficient & Lower Energy Costs

Kitchen with Appliances

Making your home more energy-efficient might sound like a big undertaking, but it is much easier than you think.

There are several minor changes you can make to/within your home that will improve your energy efficiency.

Energy-efficient practices and/or products use less energy to perform the same task. For example, an LED light bulb uses less energy but produces the same amount of light.

The benefits are vast, as energy efficiency reduces greenhouse gas emissions, reduces electricity demand, and saves you money on your energy bills.

11 Ways to Make Your Home More Energy-Efficient

For anything that uses energy, there is an opportunity to improve its efficiency.

There are two ways to improve energy efficiency: one is by purchasing products that will improve energy efficiency (e.g., smart thermostat), and the other is through improvements to your home’s infrastructure or changing habits (e.g., adding insulation or turning off the lights when you leave a room).

The average household spends nearly $1,900 annually on energy bills, which could be reduced by over 24% (or $450) by upgrading to energy-efficient products and making minor improvements/adjustments to your home.

Here are some general tips to help make your home more energy-efficient.

1. Conduct a Home Energy Assessment

Certified professionals conduct home energy assessments. A professional home energy assessment allows homeowners to understand better where their home is losing energy and why.

The professional assessor will generate a comprehensive report summarizing your home’s characteristics.

The report will also provide recommendations for energy-efficient upgrades or actions that will help you save energy and money on your energy bills. Depending on where you live, energy rebates may be associated with certain energy-efficient upgrades.

The professional should be able to advise you on what rebates are available and how to claim them.

2. Buy Energy Star Certified Products

Energy Star is an internationally recognized and trusted symbol representing high efficiency backed by many governments (e.g., the United States and Canada). It means the product, new home, building, or industrial facility has been certified as energy-efficient.

The Energy Star label was made to reduce greenhouse gas emissions caused by inefficient energy use and make it easier for consumers to identify and purchase energy-efficient products.

An Energy Star dishwasher uses 12% less energy; an Energy Star fridge uses 10% less energy. An Energy Star washing machine uses 25% less energy and 33% less water, an Energy Star dryer uses 20% less energy, and an Energy Star-certified television uses 25% less energy than conventional appliances.

3. Reduce Standby Power Consumption

Believe it or not, appliances and other electronics draw power/electricity when plugged in, whether or not they are being used.

It is estimated that standby power consumption accounts for anywhere from five to 10 percent of your monthly electricity bill.

You can reduce your standby power consumption by using smart power bars, unplugging electronics when not in use, and using smart home devices.

4. Clean Large Appliances

Performing regular maintenance and cleaning your large appliances can not only help extend their lifespan but can also help them run more efficiently. For example, cleaning the condenser coils on your fridge/freezing regularly can save you up to $500 over a 10–15-year period.

Similarly, ensuring your stovetop burners and reflectors are clean will help you conserve energy, as a dirty reflector will absorb more heat rather than reflect it back to the cooking pot or pan bottom.

If an appliance is dirty or the filter is trapped with lint, pet hair, or other debris, it must work harder to get the same result.

Many new large appliances, such as dishwashers or washing machines, have built-in clean cycles that you can run regularly. Scheduling or performing regular maintenance and cleaning will go a long way in ensuring that your appliances are working as efficiently as possible.

5. Switch Your Light Bulbs

Switching to LED light bulbs is one of the easiest things you can do to improve your home’s energy efficiency.

LED light bulbs use 70-90% less energy than an incandescent light bulb and provide the same amount of light. They save energy and are safer because they emit very little heat, reducing the risk of combustion or burnt fingers. They are sturdier and less likely to break, and long-lasting.

An LED light bulb can last 3 to 5 times longer than a compact fluorescent lamp and 30 times longer than an incandescent light bulb.

6. Use Smart Thermostats

Smart thermostats are Wi-Fi enabled devices that automatically adjust heating and cooling temperatures in your home for optimal performance. They can be controlled with a phone, tablet, or any other internet-connected device.

Smart thermostats typically allow you to schedule your desired temperature setting while adapting to your schedule and habits (e.g., the thermostat knows when you are not home).

Smart thermostats save energy and money because they only cool and heat the home when necessary by learning about your habits and schedule. They will prompt you to adopt more energy-efficient practices and remind you when to perform regular maintenance on your furnace.

7. Perform a Furnace Maintenance

Regular maintenance on all significant furnaces is key to extending their lifespan but also ensures that they are operating as efficiently as possible. Changing or cleaning your furnace filter every three months or as needed is essential to maintain efficiency.

Oil-fired furnaces need annual maintenance, while natural gas and propane furnaces should be serviced at least every two years. This may seem like another expense, but it will save you money and energy in the long term.

If you are in the market for a new furnace, it is best to look for an Energy Star-certified furnace with an energy rating of at least 95% for gas and 85% for oil. Switching to an energy-efficient furnace can reduce your annual energy bill by up to 35%.

8. Switch to a Tankless Water Heater

Water heaters are a huge energy consumer, using natural gas, electricity, fuel oil, or propane to generate hot water.

Storage tank water heaters are usually between 30 and 60 gallons, continuously heating all the water in the tank whether or not you need it all. The benefit is that you have hot water on demand, but it costs you money in energy usage to keep all the water hot at all times.

A tankless water heater is more energy-efficient and has a longer lifespan. It does not store water in a tank. Instead, it heats the water as it passes through the unit. Heating water, when needed, eliminates the standby energy losses you experience with a storage tank.

Tankless water heaters are much smaller, saving you floor space, and can fit tight spaces. Tankless water heaters can be 24% to 34% more energy-efficient than conventional storage tank water heaters.

9. Make a Home Improvement

Making larger-scale improvements can go a long way to making your home more energy-efficient. For example, if you have an older home, the windows are probably drafty, meaning that you are spending more energy to heat your home than if you had airtight windows.

That said, just because your windows generate a draft does not necessarily mean you have to replace them. You can try caulking around the window frames, installing or replacing weatherstripping, or adding a door sweep.

You can also apply exterior window film during the winter to help keep the cold air out. Replacing old and energy-efficient windows (e.g., double-glazing windows) will reduce heat exchange and air leaks.

While this will be a reasonably steep cost upfront, energy-efficient windows will save you up to 50% on your energy bills, generating long-term savings.

10. Install Insulation in Your Home

Insulation plays a vital role in the energy efficiency of your home. Proper insulation ensures that you don’t need to use as much energy to keep your house warm in the winter or excellent in the summer.

Adding more insulation to an attic can also help to keep warm air inside during the colder months.

Installing insulation in the wall cavities and the roof helps to increase energy efficiency, as significantly less energy is required to heat the home than without insulation.

Research shows that installing insulation in just 4 million homes – around 4% of North America’s total number of homes – removes the same amount of carbon dioxide from the atmosphere, equivalent to almost 700 million trees.

If all parts of the United States that receive cold winters padded their homes with thick insulation walls, imagine the benefit of this on the environment.

11. Install Solar Panels

Solar panels capture energy from the sun and convert it into thermal or electrical energy. Solar technology can generate electricity and provide light and heat water for domestic, commercial, or industrial use.

Installing solar panels requires a significant investment but can be worthwhile given the tax incentives, rebates, and long-term benefits/savings.
