Energy saver devices can increase the life of appliances by protecting them from power surges
Energy saver devices are designed to reduce electricity consumption and, consequently, electricity bills. They work by storing electricity inside them and then releasing it in a smoother way, without the spikes and surges that are common in the electricity supply coming from the grid. This unstable current can harm appliances and wiring circuits, reducing their lifespan.
Energy saver devices act as a filter, limiting the potential damage caused by sudden electrical surges. They can also help to reduce power wastage from inductive loads, such as air conditioning units, refrigerators, and computers. By minimising power fluctuations, they can protect appliances and extend their lifespan.
While energy saver devices can help, there are other ways to protect appliances from power surges. Power strips with surge protection features can prevent power surges from impacting appliances by absorbing or redirecting excess voltage. Whole-house surge protectors can also be installed on the service panel or breaker box to prevent surges from entering the house's electrical systems.
It is important to note that some people have questioned the effectiveness of energy saver devices, claiming that they do not deliver the promised level of energy savings. When considering an energy saver device, it is wise to look at the different factors that affect the specifications to determine if it aligns with your requirements.

Power savers can reduce consumption by 25-40% for older models
Power savers are small electrical devices that can be plugged into a power socket to improve energy efficiency and reduce consumption. They are designed to cut down on energy wastage from appliances, making them use electricity more efficiently. By employing a network of capacitors, power savers store electricity and release it in a smoother way, without the spikes and surges that are common in the electricity supplied to homes and commercial buildings. This minimises power loss, meaning that appliances will be able to do more work for the same amount of supplied energy.
Manufacturers claim that older models of power savers can reduce consumption by 25-40%. However, some sources state that these figures are misleading, and the actual energy savings may be lower than expected. Newer models of power savers are said to be more effective, with some claiming energy savings of up to 80-90%.
The effectiveness of a power saver also depends on several factors, such as the brand and model of the device, the amount of inductive load in the home, and any other energy-saving measures already in place. Homes with higher power usage and older electrical wiring tend to have greater power loss, so power savers may be more beneficial in these cases.
It is important to note that there are alternative ways to save energy and reduce electricity bills. For example, using high-efficiency detergent in front-loading washing machines, shutting down computers when not in use, and unplugging appliances that use "vampire power" can all contribute to energy savings.

Power strips prevent phantom energy loss by cutting electricity to unused appliances
Power strips are an effective way to prevent phantom energy loss and cut electricity usage from unused appliances.
Phantom energy, also known as vampire power, is the electricity consumed by appliances that are plugged in but not in use. It is a significant issue, accounting for 5 to 10% of residential energy use in the United States, which can cost households up to $100 per year. Modern appliances with digital displays, internet connectivity, and standby modes are common culprits of phantom energy consumption.
Power strips with on/off switches, also known as smart power strips, can be used to combat this issue. By plugging multiple appliances into a power strip and turning off the strip when the appliances are not in use, you can completely cut the power to them. This is more convenient and effective than manually unplugging each device or flipping multiple light switches.
Smart power strips are even more advanced, as they can detect when devices are in standby mode and automatically cut the power. This feature ensures that no vampire power is being drawn by devices that are turned off but still plugged in.
By utilising power strips, individuals can take control of their energy usage, reduce phantom energy loss, and make a positive impact on both the environment and their electricity bills.

Energy-saving light bulbs, smart thermostats and energy monitors can help save electricity
Energy-saving light bulbs, smart thermostats, and energy monitors can all help reduce electricity consumption and lower energy bills.
Energy-saving light bulbs are a simple way to reduce electricity usage. These bulbs are designed to use less electricity to produce the same amount of light as regular incandescent bulbs, which waste a lot of energy by converting most of the energy they use into heat rather than light.
Smart thermostats are another effective way to save electricity. These devices are Wi-Fi-enabled and can automatically adjust heating and cooling temperatures in your home for optimal performance. Certain smart thermostats can learn your preferences and establish a schedule that adjusts to energy-saving temperatures when you are asleep or away. For example, if you leave the house, it can detect this and 'set back' the heating or air conditioning, and then adjust the temperature again when you are on your way home so that you return to a comfortable home. Smart thermostats that earn the ENERGY STAR label have been independently certified to deliver energy savings.
Energy monitors, such as the Sense Energy Monitor, provide insights into your home's energy use and activity, allowing you to track your electricity usage in real-time. This helps you to understand your energy usage patterns and find ways to save. For example, you can see when someone leaves a light on and turn it off remotely, or set custom notifications for critical devices. Energy monitors can also help to prevent power surges, which can damage appliances and impact their lifespan.

Using cold water and high-efficiency detergent can reduce energy consumption when doing laundry
When it comes to laundry, small changes can make a big difference in energy consumption. One of the easiest ways to reduce energy use is to wash your clothes in cold water. According to ENERGY STAR, water heating accounts for about 90% of the energy consumed by a washing machine. Therefore, switching to cold water can cut a load's energy use in half. Cold water is effective at cleaning your clothes unless you're dealing with oily stains or sick bedding.
Another way to make your laundry routine more energy-efficient is to use high-efficiency (HE) detergent. HE detergents are specifically formulated for today's high-efficiency, low-water-use washers. They contain enzymes that effectively remove stains and grime at lower water temperatures. Additionally, they reduce washing and rinsing time compared to regular detergents, which may cause excess suds and extended wash cycles, using more water and energy.
To further reduce energy consumption, it is recommended to wash and dry full loads whenever possible. A washer uses the same amount of energy regardless of the load size, so waiting for a full load helps reduce the number of wash cycles and conserve water and energy. Additionally, consider air-drying your clothes on a clothesline or drying rack whenever possible. Air-drying is one of the most energy-efficient and cost-effective ways to dry your laundry, and it also helps your clothes last longer.
Finally, if you have a dryer, it is important to maintain it properly to ensure energy efficiency. Regularly clean the lint filter after each use to improve airflow and prevent fire hazards. Using a lower heat setting with a longer dry cycle can also reduce energy consumption, as it is more efficient than a shorter cycle at a higher temperature. Additionally, consider using wool or rubber dryer balls to increase air circulation, reduce drying time, and minimise wrinkles and static electricity.
