What You'll Learn
Use energy-efficient appliances
One of the most effective ways to reduce electricity consumption at home is to replace old, inefficient appliances with modern, energy-efficient models. These appliances are designed to consume less electricity without compromising performance. Look for the ENERGY STAR label, a government-backed symbol of energy efficiency, when purchasing new appliances.
Refrigerators, for example, are a common source of high electricity usage. Upgrading to a power-efficient model can make a significant difference in your energy consumption and bills. Similarly, older kitchen appliances like stoves and ovens tend to be less efficient. Modern energy-efficient alternatives are better optimized and can help reduce electricity usage.
Another area to consider is heating and cooling systems. Upgrading to a smart thermostat, for instance, can reduce heating and cooling costs by up to 15%. These thermostats learn your habits and automatically adjust the temperature, allowing for more efficient energy usage. Additionally, consider annual inspections and servicing of your heating system to ensure efficient operation.
Small appliances, such as kettles, can also contribute to high electricity usage. Overfilling kettles with more water than needed wastes energy and increases costs. Simple adjustments, like only filling the kettle with the amount of water required, can lead to notable savings over time.
Lastly, entertainment devices like televisions, cable boxes, and game consoles often consume electricity even when not in use. Using power strips and turning them off when not in use can help mitigate this issue and reduce your overall electricity consumption.

Reduce 'phantom loads' from electronics
Even when they are turned off, electronics can still consume energy, a phenomenon known as "phantom loads". This can be a significant drain on energy and your wallet.
One way to reduce phantom loads is to use smart power strips. These cut the power to devices when they are not in use, and are particularly useful for devices that are always on, like computers and televisions. Plug your devices into a power strip and turn off the power strip when you are not using them. You can also buy a 'standby saver' which turns off all your appliances at once.
Another way to reduce phantom loads is to be mindful of your charging habits. Chargers that are plugged in draw power even when no device is attached. Unplug your chargers once your phones, tablets or other devices are fully charged.
You can also reduce your phantom loads by being mindful of your water heating habits. Heating water is a significant energy expense. You can reduce your energy consumption by turning your hot water tank down to 120°F. Insulating your hot water pipes and installing a water heater insulation blanket on your tank will also help reduce your energy consumption. On-demand water heaters are often the most efficient choice, as water is only heated when it is in use.
Finally, be mindful of your cooking habits. A microwave uses half the energy of a conventional oven. If you do use a conventional oven, don't pre-heat it for longer than necessary. Pre-heat food in the microwave and then finish cooking it in the oven. Only run your dishwasher when it is full, and use the cold water setting on your washer.

Insulate your home
Insulation is key to minimising electricity consumption at home. Proper insulation helps maintain the desired temperature in your home, keeping the cold out in winter and excess heat out in summer.
Attic, Walls and Floors
First, check your attic, walls and floors for adequate insulation. If your home is poorly insulated, heat will escape in winter, and your home will be harder to cool in summer. You can insulate your attic by ensuring it has enough insulation between and over the floor joists. For walls, check for insulation in the cavities of external walls, and consider adding more if your home is older and may have settled, leaving gaps in the insulation. You can also add insulation to floors, especially those over unheated spaces like garages or cellars.
Doors and Windows
Sealing drafts around doors and windows is another important step. Use weather stripping or caulking to seal gaps, and add a door sweep to the bottom of exterior doors. If your windows are single-glazed, consider installing double or triple-glazed windows, or use exterior window film to increase insulation. Remember to close your blinds or drapes at night to cut heat loss through windows.
Ductwork and Hot Water Pipes
If your home has a heating system with ductwork, ensure it is well-maintained and insulated, especially in areas like basements or crawl spaces. Also, insulate hot water pipes and your hot water tank to prevent heat loss. An insulating blanket can be wrapped around electric hot water tanks, and for ducts, use heating-vent tape on all visible joints.
Smart Thermostats
Smart thermostats can help reduce heating and cooling costs by learning your habits and automatically adjusting the temperature. They can be controlled remotely via an app, allowing you to manage your heating or cooling costs even when you're not at home.
By implementing these insulation measures, you can significantly reduce electricity consumption and create a more comfortable and energy-efficient home.

Lower water heating costs
Consider installing a smart thermostat, which can reduce heating and cooling costs by up to 15%. These thermostats learn your habits and adjust the temperature automatically. For example, if you usually turn the temperature down before bed, a smart thermostat will start doing this automatically. You can also control it remotely via an app, which is useful if your schedule changes.
Simple practices like taking shorter showers, fixing leaks, and installing low-flow fixtures can also reduce water usage and the energy required to heat it.
To further reduce your energy consumption, remember to turn off appliances at the plug when they are not in use. Even when turned off, electronics can still consume energy in standby mode, a phenomenon known as "phantom loads". Smart power strips can help with this by cutting the power to devices when they are not in use.

Understand your energy bill
Understanding your energy bill is a crucial step in minimising your electricity consumption at home. Firstly, it is important to know what the different parts of your energy bill mean. This empowers you to stay in control of your bills and make informed decisions to reduce your electricity usage.
One way to better understand your energy bill is to use a smart energy monitor. These devices connect to your electricity meter and provide real-time data on your energy usage. Some models also allow you to set targets and receive alerts when you exceed them. For instance, you can set a target to reduce your water heating costs by lowering the temperature on your hot water tank. For every 10-degree reduction in temperature, you can save between 3% and 5% on your water heating costs.
Additionally, keeping an energy consumption diary can help you track your usage trends. Make a note every time you use energy, and use graphic examples to identify areas where you can further reduce your consumption. For instance, you can make a note of how often you use your oven and consider switching to a microwave, which uses half the energy of a conventional oven. Similarly, you can note how often you boil the kettle with more water than you need, and switch to only boiling the amount of water you require. This simple change can save you money on your electricity bill.
Finally, understanding your energy bill involves knowing how to save energy in various areas of your home. For example, you can save energy by turning down your thermostat when you are not home or at night, and by insulating your ductwork to prevent heat loss. You can also reduce your "phantom load" by ensuring that appliances like your computer and television are truly turned off when not in use.
