Reducing electricity usage is an important topic for those wanting to save money and reduce their environmental impact. Many households and businesses are looking for ways to lower their electricity consumption, and there are a variety of methods to achieve this. Some common strategies include changing daily habits, such as turning off lights and unplugging unused devices, as well as optimising the use of appliances that consume the most energy, such as TVs, fridges, and washing machines. Additionally, modern technology, such as timers and motion sensors, can be utilised to improve energy efficiency, and energy audits can help identify areas of improvement. This topic is relevant to anyone looking to reduce their electricity bills and carbon footprint.

What You'll Learn
Use energy-efficient appliances and light bulbs
One of the most effective ways to reduce electricity usage is to use energy-efficient appliances and light bulbs. Lighting accounts for around 15% of an average home's electricity use, and the average household saves about $225 in energy costs per year by using LED lighting.
When buying new appliances, it is worth considering whether you need the most advanced model. For example, a TV with a 65-inch screen may be more appealing, but a smaller one will use less energy. Similarly, when purchasing a washing machine, opt for a model with a lower load capacity. This will save money on electricity and water bills. Older appliances tend to be less energy-efficient, so it may be worth investing in an upgrade.
Light Emitting Diodes (LEDs) are the most energy-efficient lighting technology available today. LEDs use up to 90% less energy and last up to 25 times longer than traditional incandescent bulbs. They are available in a variety of colours and hues, and some bulbs can be tuned to different colours or shades of white light. LEDs also work well in cold environments and are durable, making them suitable for both indoor and outdoor use. Solar-powered LED lighting is also an option for outdoor lighting.
Although LEDs are more expensive than traditional incandescent bulbs, their longevity and low energy use mean they save money in the long run. Look for the ENERGY STAR label when purchasing LED bulbs and appliances to ensure you are getting high-quality, energy-efficient products. A comprehensive package of ENERGY STAR-certified appliances can reduce energy costs while offering improved performance and durability.

Reduce heating and cooling
Heating and cooling account for a significant portion of electricity usage. Here are some ways to reduce electricity usage for heating and cooling:
Smart Power Strips
Use smart power strips, also known as advanced power strips, to shut off the power to electronics when they are not in use. These can be set to turn off appliances at a certain time, after a period of inactivity, or through remote switches. This can help to reduce "phantom loads", where electronics draw a small amount of electricity even when not in use.
Smart Thermostats
Smart thermostats can help reduce heating and cooling energy use by automatically turning off or reducing heating and cooling when you are asleep or away. Some models can also indicate when to replace air filters or address HVAC system problems, improving efficiency.
Insulation and Air Sealing
Insulation plays a crucial role in retaining heat during winter and keeping heat out during summer. Weatherizing your home by sealing air leaks around vents, windows, and doors with caulk or weather stripping can help reduce heating and cooling expenses.
Water Heating
Water heating contributes significantly to total energy usage. Lowering your water heater's temperature dial to 120 degrees Fahrenheit can save up to 5% in energy costs for every 10-degree reduction. Insulating the first six feet of hot and cold water pipes can also help reduce expenses.
Furnace and Boiler Maintenance
Annual professional maintenance of your heating system, including boilers, furnaces, and heat pumps, can improve efficiency and extend the life of the unit. Regularly replacing the filter on your furnace (every two months) and keeping ducts and grills clean can also improve efficiency by preventing dust and lint buildup.

Eliminate 'phantom' power loads
Eliminating phantom power loads is a great way to reduce electricity usage. Phantom power loads, also known as 'vampiric power drain', are appliances that continue to draw power even when they are switched off or on standby. Examples of such appliances include televisions, coffee makers, microwaves, audio systems, computers, and game consoles.
To eliminate phantom power loads, it is important to unplug appliances that are not in use. If you have several appliances plugged into a power strip, you can simply switch the power strip off. This is a simple and effective way to ensure that no electricity is being wasted.
Another way to tackle phantom power loads is to use smart power strips, which automatically cut power to appliances when they are not in use. These can be especially useful for appliances that are hard to reach or easily forgotten about, such as those behind furniture or in storage.
It is worth noting that some appliances, such as DVRs, are constantly running computers and can be significant sources of vampiric power drain. Upgrading older appliances to more energy-efficient models can also help to reduce electricity usage.
By implementing these strategies, you can significantly reduce your electricity usage and save on your energy bills.

Weatherproof your home
Weatherproofing your home is an effective way to reduce electricity usage. It involves sealing gaps and protecting electrical connections to prevent water ingress and manage indoor temperature. Here are some ways to weatherproof your home:
Draught-proofing and insulation: Identify areas where cold air can enter and warm air can escape, such as windows, doors, attics, and basements. Seal gaps around windows and doors with weatherstripping or caulk. Insulate attics and basements to maintain a consistent indoor temperature, reducing the burden on your heating and cooling systems.
Waterproof electrical connections: Protecting electrical connections from moisture is crucial to prevent failures and ensure long-term electrical safety. Use waterproof wire connectors with gel filling, rubber gaskets, or sealing caps. Alternatively, apply liquid electrical tape, self-fusing silicone tape, or adhesive-lined heat shrink tubes to exposed wires. These methods create a secure barrier against water ingress.
Exterior lighting: Choose halogen lightbulbs for outdoor lighting as they consume 25% less electricity than incandescent bulbs without sacrificing brightness. Additionally, ensure that outdoor lighting fixtures are weatherproof to prevent electrical issues caused by rain or humidity.
Wall treatments: Consider waterproofing your walls to prevent rising damp and reduce the impact of external weather conditions on your indoor environment. Cavity wall linings and waterproof coatings can help regulate indoor temperature and humidity levels, reducing the need for excessive heating or cooling.
Remember that proper weatherproofing techniques and reliable materials are essential to effectively weatherproofing your home and reducing electricity usage. Regular maintenance of your weatherproofing measures will also ensure their longevity and effectiveness.

Reduce water heating usage
Water heating accounts for about 18% of your home's energy use and is typically the second-largest energy expense in any home. Here are some ways to reduce water heating usage:
Insulate your water heater and pipes
Insulating your water heater and the first 6 feet of both the hot and cold water pipes connected to the unit can help reduce heat loss. This, in turn, prevents the unit from turning on as frequently, reducing energy consumption.
Lower the temperature setting
Although many manufacturers set their water heater thermostats at 140°F, most households find 120°F comfortable. This small decrease can cut costs, reduce scalding, and slow mineral buildup and corrosion in your heater and pipes.
Fix leaks
A leak of one drip per second can waste 1,661 gallons of water and cost up to $35 per year. Fixing leaks in faucets, showerheads, and pipes can significantly reduce hot water usage.
Install low-flow fixtures
Low-flow showerheads and faucets can help conserve hot water. Aerating showerheads mix air with water to form a misty spray, while laminar-flow showerheads form individual streams. Both types of low-flow showerheads can provide a comfortable shower experience while reducing hot water usage.
Upgrade to energy-efficient appliances
Older appliances like dishwashers and washing machines can be less energy-efficient. Upgrading to ENERGY STAR-certified appliances can significantly reduce energy consumption and lower water heating costs.
