What You'll Learn
Turn off appliances and lights when not in use
Turning off appliances and lights when they are not in use is a simple yet effective way to save electricity and money at home.
Firstly, it is important to get into the habit of switching off lights when leaving a room. This is a simple action that can make a big difference in reducing energy waste. It is also beneficial to utilise natural daylight as much as possible, turning off lights in rooms with windows during the day.
Secondly, unplug appliances when they are not in use. Many appliances continue to draw power when plugged in, even when switched off, so it is good practice to unplug them. This is especially true for appliances with a standby mode, such as TVs, computers, and phone chargers. By unplugging these appliances, you can eliminate "standby" electricity loss.
Thirdly, it is important to be mindful of appliances that use a lot of electricity. For example, try to only run the washing machine and dishwasher when they are fully loaded. Similarly, try to avoid using the dryer, opting to air-dry your clothes instead. When using the dryer, remember to clean the lint filter after each load. These simple actions can help to reduce the amount of electricity used by these appliances.
Finally, consider investing in smart power strips. These are advanced power strips that shut off the power to electronics when they are not in use, either at an assigned time or after a period of inactivity. This is a convenient way to ensure that appliances are not using electricity unnecessarily.

Use smart power strips to save on 'phantom loads'
Smart power strips, also known as advanced power strips, are an effective way to save energy and money at home. They are designed to eliminate the problem of "phantom loads", which occur when electronics continue to draw power even when they are switched off or in standby mode.
Phantom loads can be a significant source of energy waste, as many electronic devices are constantly drawing small amounts of power, even when they are not in use. This can add up to a considerable amount of wasted energy over time, increasing electricity bills and contributing to environmental harm.
Smart power strips address this issue by automatically shutting off the power to electronics when they are not in use. They can be programmed to turn off appliances at a specific time, after a period of inactivity, through remote switches, or based on the status of a "master" device. For example, if your television is connected to a smart power strip, you can set it up so that when you turn off the TV, the power strip automatically cuts power to all connected devices, such as gaming consoles or streaming devices, ensuring that no energy is wasted.
By using smart power strips, you can significantly reduce your energy consumption and lower your electricity costs. They are a simple yet effective way to make your home more energy-efficient and environmentally friendly. In addition, smart power strips often have built-in surge protection, which can help protect your electronics from power surges and further extend their lifespan.
Overall, smart power strips are a valuable tool for anyone looking to reduce their energy usage, save money on electricity bills, and minimise their environmental impact. They are a convenient and efficient way to address the issue of phantom loads and ensure that your home is running as energy-efficiently as possible.

Insulate your home to retain heat
Insulating your home is a great way to retain heat and save money on electricity. Heat rises, so a home without loft insulation loses around a quarter of its heat through the roof. Insulating an attic with foam or a simple reflective foil material stapled to the roof rafters can effectively reduce heating costs. If you're building a new home or remodelling, ensure any attic decking that provides additional storage space or a platform for a heating/cooling unit is raised above the ceiling joists to leave room for adequate insulation.
Basements are notorious for problems with water intrusion, humidity, and mould. A properly insulated basement foundation will keep rooms more comfortable, prevent moisture problems, and save money on heating. In most cases, a basement with insulation installed on its exterior walls should be considered a conditioned space. If you're insulating floors above an unconditioned garage, seal all possible sources of air leakage first and install an air barrier to prevent cold air from impacting the insulation.
Double glazing is an effective way to reduce heat transfer from your home, but it can be expensive. A cheaper alternative is secondary glazing, which is a pane of glass, plastic, or film fitted in parallel to the window. While not as efficient, secondary glazing retains the original character of the windows and is considerably cheaper.
Other ways to insulate your home include using thermal curtains, blinds, or blackout curtains, and installing a smart thermostat set at 19°C.

Use energy-efficient light bulbs
Using energy-efficient light bulbs is one of the easiest ways to save electricity at home. Traditional incandescent bulbs are inefficient, as most of the energy they use is lost as heat rather than light. By contrast, energy-efficient bulbs such as compact fluorescent lights (CFLs) and light-emitting diodes (LEDs) use significantly less energy to produce the same amount of light.
CFLs use around a quarter of the energy of incandescent bulbs and last up to 10 times longer. They are also cheaper to run, saving around $30 over the bulb's lifetime. However, CFLs do contain a small amount of mercury, so they must be disposed of properly at a local specialist recycling centre.
LED bulbs are another energy-efficient alternative. They use around 90% less energy than incandescent bulbs and can last up to 25 times longer. LED bulbs are also more durable and less fragile than CFLs and incandescent bulbs. They are an especially good choice for outdoor lighting, as their longevity means they do not need to be replaced as frequently.
In addition to using energy-efficient bulbs, there are other ways to reduce energy consumption from lighting. Motion sensors and timers can be used to ensure lights are only on when needed, and natural daylight can be utilised by opening curtains and blinds during the day.

Adjust your thermostat and use natural sunlight
Adjusting your thermostat and making use of natural sunlight are effective ways to save electricity at home.
Adjusting Your Thermostat
Adjusting your thermostat according to the season and time of day is a simple way to save electricity. In the winter, set your thermostat to around 68°F to 70°F while you're awake and present in the house. Set the thermostat to a lower temperature when you're asleep or away from home for four hours or more. In the summer, keep your house warmer than normal when you are away, and set the thermostat to a comfortable temperature when you are at home and need cooling.
Programmable thermostats can help you automate these adjustments, allowing you to set a pre-set schedule for the heating or air conditioning. They can store and repeat multiple daily settings (six or more temperature settings a day) and can be manually overridden without affecting the rest of the daily or weekly program. You can save as much as 10% a year on heating and cooling by simply turning your thermostat back 7°-10°F for eight hours a day from its normal setting.
When programming your thermostat, consider the sleep schedules and daily routines of everyone in the household. The location of your thermostat matters; it must be on an interior wall away from direct sunlight, drafts, doorways, skylights, and windows to operate properly and avoid "ghost readings" or unnecessary furnace or air conditioner cycling. Avoid placing lamps or TV sets near your thermostat, as the thermostat may sense heat from these appliances and cause the air conditioner to run longer than necessary.
Embracing Natural Sunlight
Maximizing natural light in your home is a powerful way to save energy and reduce reliance on artificial lighting. Strategically placed windows can be used to optimize natural light, allowing sunlight to fill various rooms throughout the day. Using sheer curtains or blinds can diffuse intense light while maintaining brightness. Positioning mirrors opposite windows can reflect light, creating a sense of spaciousness.
In the summer, closing window shades can reduce the ingress of solar heat. In the winter, opening window shades allows direct sunlight to enter and naturally heat your home. Using natural ventilation and fans instead of air conditioning saves energy and lowers cooling costs. Open windows in the cool mornings and evenings, and keep them closed during the hottest parts of the day. Ceiling fans can circulate air, allowing you to raise the thermostat without sacrificing comfort.
