In 2024, every single one of us needs to do everything possible to save energy. Climate change is happening now, and we simply cannot afford to wait any longer.

Fortunately, there are a number of simple changes we can all make to conserve energy in our daily routine, without impacting our quality of life.

In fact, following these tips will save you money on your electricity bill as well as doing your bit to save the planet.

I touched on energy conservation a while back in my Simple Tips To Lead a Greener Lifestyle article.

Today, I'm going to expand on that and give you even more tips that can make a real difference to your energy usage.

What Is Energy Conservation?

Energy conservation is the deliberate act of finding ways to use less energy to lower costs as a consumer and reduce our environmental impact.

Put another way; the less energy (gas, electricity, etc.) you buy from the utility company, the better it will be for your wallet AND the planet.

Energy Saving Tips To Save A Few Bucks And (Hopefully) The Planet

Energy conservation is an enormous topic. If I tried to cover every aspect of your life, this article would quickly become long and tedious.

So, I’ll concentrate on one area of your life where you should have the most control—home energy use.

If this article is well received, I will, at a later date, broaden out into energy conservation tips for work, school, travel, etc. Let me know if this is something you’d like to see in the future.

Outside Your Home

How to save energy outside the home


Leave your car at home and walk, cycle or take public transport as much as possible. The less you use your car, the less gas it will consume.

When you do use your car, ensure it’s as efficient as it possibly can be. Service it regularly and always keep the tires at the correct pressure.

Outside Lighting

Your outside lighting is probably used more than you realize.

Ensure that energy-efficient light fittings and bulbs are used.

If your current outside lighting is outdated and inefficient, maybe consider upgrading to motion sensor technology, so the lights only come on when they’re needed.

Solar Panels

Power your house and all your appliances for free by harnessing solar energy.

A solar installation pays for itself (on average) after 8 years. After that, your electricity is basically free, and you can even sell your excess energy output back to the grid!

Steph has written an excellent article all about the pros and cons of solar energy.

Inside Your Home - Basement

save energy in the basement - heating and cooling


It’s common to have excess moisture in the basement, so many U.S. homes will have a dehumidifier to eliminate condensation, musty smells, mold, mildew, rotting wood, etc.

If you decide that a dehumidifier is needed, then make sure you get the right size for your needs. ENERGY STAR has you covered with this guide to their efficiency criteria.


The best tip here is a simple one; whenever possible, dry your clothes outside using the power of that big yellow thing in the sky.

If you have to use a clothes dryer, ensure that you use the correct setting and don’t over-dry your laundry. It wastes electricity and damages your clothes.

Cleaning the lint trap is crucial to allow proper airflow.

HVAC System (Heating, Ventilation, Air Conditioning)

ENERGY STAR estimates that around 50% of your household energy use is heating and cooling, so it’s essential to have a system that perfectly meets your needs.

Make sure you do your research and go for an energy-efficient unit that’s the correct size for your needs.

Bigger is not always better here.

A unit too big can become noisy. A unit too small might struggle to sufficiently heat/cool your home and fail too soon due to increased load.

Also, remember to clean and replace the air filter regularly to reduce your heating and cooling costs.

Rim Joist

A regularly overlooked source of heat loss from your home is along the top of the basement wall, where it comes into contact with the wooden house frame. This is known as the 'rim joist' or 'band joist'.

Seal any gaps with expanding foam or caulk to prevent cold air from leaking from the basement into your house.

Washing Machine

Only run the washer when it’s full and wash in cold water whenever possible. Washing full loads can save you more than 3,400 gallons of water each year.

When your old washing machine reaches the end of its life, ensure that the replacement appliance is as energy-efficient as it can be.

ENERGY STAR Certified washing machines use approximately 30% less energy and 50% less water than started washing machines.

Water Heater

Tankless water heaters can reduce your energy bills because they heat water on demand, so you don’t heat water that you’ll never use.

If you do go for a storage water heater, make sure it is energy-efficient and well-insulated. Again, looking for ENERGY STAR-approved water heaters is a great place to start.

Keep turning the water heater temperature down by one degree a day until you start to notice the difference. Then turn it back up one degree. That should give you the perfect temperature and reduce your water heating costs.

If you have an older water heater, you can improve its efficiency by popping on a water heater insulating jacket.

While you’re in insulating mode, why not also wrap the hot pipes leaving the water heater for extra savings? This is a simple but effective way to reduce energy waste, and can be done by even novice DIYers.

Remember to turn off your water heater when away from home for extended periods (holidays, etc.).

Inside Your Home - Kitchen

tips to conserve energy in the kitchen


Save water by scraping plates and dishes, rather than rinsing, before you pop them in the dishwasher.

Only run the dishwasher when it's full and use the ‘eco’ setting if available.

Avoid any drying settings. Simply open your dishwasher once the cycle has completed and let the dishes air dry. The water will have been hot and will evaporate quickly. If the dishes don’t quite dry properly in the air, you can always wipe them with a dishtowel.

If you live on your own or have a small family, consider saving the dishwasher for parties, etc. and wash/dry your daily dishes by hand.

Kitchen Sink

Repair all leaks (or have a plumber do it for you). The water heater will use less energy which will more than cover the cost of the repair.

According to ENERGY STAR, “hot water leaking at a rate of 1 drip per second can waste up to 1,661 gallons of water over the course of a year, and waste up to $35 in electricity or in natural gas”.

We have an aerator attached to our kitchen faucet to reduce the flow of water. It also makes the water light, directional, and dramatically reduces splashing.


When cooking or reheating small portions of food, try to use a microwave instead of a stove.

Not only will this initially conserve energy because your microwave is more efficient than your stove, but it will also potentially keep your kitchen cool and reduce your annual cooling costs.


Always use a pan that’s an appropriate size for the stove. A small pot on a large stove burner, for example, wastes energy.

Using a pan lid enables the contents to reach the correct temperature quicker and reduces energy use.

If you have a gas range, keep the burners clean to ensure maximum efficiency. A blue flame is a good sign. A yellow flame means the burner needs cleaning, or the stove in general needs servicing.

Range Hood

Go for an energy-efficient model. Preferably ENERGY STAR certified.


Look for the ENERGY STAR logo when purchasing a new refrigerator.

Many U.S. homes have a second refrigerator in the garage or basement. These are usually old, inefficient, and cost more to run than you think.

According to ENERGY STAR, you can save $300-$700 over five years by not running a second refrigerator. You will also prevent 5,500-20,000 pounds of greenhouse gas emissions.

Just remember to recycle your old refrigerator responsibly.

Turn your refrigerator down a few degrees to save money. Try 37 degrees Fahrenheit for your fridge and 3 degrees Fahrenheit for your freezer. Your food will not spoil.

If your refrigerator is humming and struggling to keep things cool, you might have dirty coils (the black pipelike things found on the back or bottom of your refrigerator). Simply wiping off any dust and dirt could give its efficiency a real boost.

Inside Your Home - Living Room

how to save energy in the living room

Ceiling Fan

Used smartly, ceiling fans can help you save on your energy bills.

Most modern ceiling fans have an option to allow them to spin both ways.

In the summer, make sure your fan is blowing air downward to help you feel cooler.

In the winter, reverse the direction the blades are rotating to produce an updraft and force the warm air collecting near the ceiling down into the living space.

Ceiling fans only cool the individual sitting under them, not the room, so remember to turn them off when you leave the room.

Drapes And Shades

During Winter, keep drapes and shade open during the day to capture as much heat from the sun as possible. Close them once the sun goes down to keep the heat in.

During Summer, keep drapes and shade closed to keep the sun out and the room cool.

Fireplace Damper

Fireplaces are designed to suck the air out of a room and up the chimney.

Always fully close the damper when the fireplace is not in use to prevent hot air escaping in the winter and cold air escaping in the summer.

Inside Your Home - Bathroom

tips to use less energy in the bathroom


A shower uses significantly less water and energy than a bath.

According to HuffPost, “The average bath uses 36 gallons to fill a tub, while the average shower (without the water-saving device) uses five gallons of water per minute”.

So, a two-minute shower will use 10 gallons of water compared to 36 gallons for a bath.

If you switched to a water-efficient showerhead, you would be able to cut that down even further.

Taking a cooler shower also helps save energy by not using as much hot water. I love a cold shower in the morning. Really gets the blood pumping. I’m not quite Wim Hof just yet...but I’m working on it!

Toilet And Sink

Use water-efficient toilets, faucets, etc. to bring down your water bill. Also, repair any leaks or drips.

Vent Fan

A vent fan is essential in a bathroom to extract moisture from the air and control mold and mildew growth.

Go for an energy-efficient model, such as those that carry the ENERGY STAR eco-label.

Inside Your Home - Bedroom

energy efficiency in the bedroom

Room Air Conditioner

If you need your bedroom at a specific temperature to get a good night’s sleep, you might consider a portable room air conditioner.

This is a great cost-effective option if you don’t have a HVAC system currently in place. Even if you do, running a small portable unit should use less electricity.

Take care to secure the exhaust hose properly to ensure no conditioned air is lost from your bedroom through your window.

Inside Your Home - Home Office

tips to save energy in the home office


Enable any available power-saving features, so these devices are as energy-efficient as possible.

Multi-Function Device

Save energy, space, and money by using multi-function devices.

For example, rather than using a separate printer, photocopier, scanner, and fax machine, get a device that performs all four functions.

This will conserve energy and also cut down on harmful e-waste.

Power Strips

Plug all of your home office devices into a power strip. The use of power strips has two benefits:

  1. Power strips save money: You can flick off one switch at the end of the working day and know that all your devices are no longer drawing any power.
  2. Power strips protect devices: Modern power strips protect your devices from unexpected surges in the power supply.

Inside Your Home - Attic

attic ducts and insulation

Attic Door

Warm air from your home can leak into the attic through poorly insulated attic doors. Consider upgrading to a fully insulated attic door assembly.


Chimneys and other flues that pass through your attic might have slight gaps that allow your warm home air to escape into the attic. Seal these gaps with a high-temperature sealant.


A typical home can lose up to 20% of the air in an HVAC system.

To reduce this, ensure that all ducts are free from holes and well insulted. Fix any holes you find with foil tape.

Plumbing Stacks

Plumbing stacks, electrical wires, ducts, vents, etc., running into your attic can often be surrounded by gaps that leak warm air from your home into the attic. Seal these gaps with insulating foam sealant.


Proper attic ventilation can reduce the reliance on an attic fan.

Regularly inspect and unblock soffit vents and gable vents to keep the natural air flowing.

Inside Your Home - General

general energy conservation advice

Air Register

Poor or loosely fitted air registers can cause air leaks and put extra strain on your HVAC system.

Use a high-quality silicone sealant to ensure that all registers and vents are securely fixed to floors, walls, and ceilings.

Also, be careful with placing your ecological furniture items to ensure that airflow is not blocked by chairs, tables, rugs, etc.


Look for the ENERGY STAR logo when buying new electronic appliances (TVs, DVD players, laptops, etc.).

ENERGY STAR certified products consume less electricity without sacrificing performance.

External Door Sweep

Air leaks are a significant source of heat loss during the winter.

Install a door sweep on all external doors to keep the warm air in and the cold air out.

Also, consider the age and condition of your external doors. Are they ready to be replaced with shiny new super-insulated ones?

Whatever the condition of your doors, make sure you keep them closed to keep the heat in.

Install A Programmable Thermostat

Install a programmable thermostat so you can predetermine the temperature settings for your home when you’re away on holiday or asleep, for example.

If you’re slightly more technically minded, you might want to consider a wifi-enabled thermostat that allows you to control your heating and cooling from your phone.

I use Nest and have it integrated with my phone and Alexa. This means I never heat the home when it’s empty or come home to cold water when I need a shower after a long hike.

Light Bulbs

Switch out your old, inefficient incandescent light bulbs for energy-efficient ones. Don’t forget things like bedside lamps, desk lamps, and vanity mirrors.

Energy-efficient light bulbs are more expensive to buy initially, but the savings over their lifetime far outweigh the initial cost.

Halogen bulbs, compact fluorescent lights, and LED light bulbs can use up to 80% less electricity and last up to 25 times longer than traditional bulbs.

Light Switches

Always turn off the lights in an empty room.

Don't get lazy with this. If you need motivation, just think about the size of your last utility bill. Trust me - these savings do add up!

Power Outlets

Always unplug any chargers or power adapters when they’re not in use.


Install foil insulation behind any radiators to reflect the heat away from the wall and back into your home.

Thermal Boundary

The exterior boundary of your home (walls, floor, windows, ceiling, etc.) is called the ‘envelope’ or ‘shell’.

Ensuring that these parts of your home are as insulated as possible could knock hundreds of dollars off your heating and cooling costs.


If your windows are old and drafty, consider upgrading to triple glazing.

If new windows are too expensive, you can use weather sealing tape to stop minor drafts.

Who Are ENERGY STAR (And Why You Should Care)

Energy Star is a program in the United States that helps people save money and protect the environment. It does this by certifying products and buildings that use less energy.

If you see the Energy Star label, it means the product or building meets strict energy efficiency guidelines set by the U.S. Environmental Protection Agency (EPA). The label can be found on many items, like appliances, office equipment, lighting, and even new homes and commercial buildings.

Using Energy Star products helps reduce electricity bills and fight against climate change by using less energy.

In this article, you can read more about ENERGY STAR and over 200 other eco-labels.

Frequently Asked Questions

What Uses The Most Energy In Your Home?

According to GreenLogic, the top five energy users in your home are:

  1. Air conditioning and heating
  2. Water heating
  3. Appliances (refrigerator, washer/dryer, electric oven/stove, dishwasher)
  4. Lighting
  5. Television and other media equipment

Do Energy Saving Devices Really Work?

Yes, legitimate energy-saving devices do really work. ENERGY STAR certified products, for example, helped Americans save nearly 500 billion kilowatt-hours of electricity and avoid $39 billion in energy costs in 2019 alone.

Does Turning Off the TV Save Electricity?

Yes, turning your TVs off at the wall when not in use will definitely save electricity, although maybe not as much as you might think.

According to Verde Energy, most modern TVs consume less than 5 watts per year when in standby mode. This works out at only a few dollars.

However, if you have multiple TVs, it can soon add up.

The Final Word

I hope you found this article useful and managed to take away at least one nugget of information that will save you a few bucks...or more!

All these ways to conserve energy are simple to implement yourself.

However, If you’ve been inspired and want to save even more money, maybe consider a home energy audit and receive expert professional guidance on how to best save energy around the home.

I’ll leave you with one final thought.

Saving energy around the home is a great way to start reducing your energy bill.

To reduce your energy bill even further, you need to make sure you’re never paying more for your utilities than you need to do.

Entering your zip code into sites such as Choose Energy will give you the peace of mind that your energy bill is the lowest it can be.

These services are constantly expanding their reach, so I’d recommend checking back every few months if your zip code is currently not covered.
