Many household items waste electricity, and it is important to identify them to save money and protect the environment. Heating and cooling appliances are the biggest electricity consumers in the average household, with air conditioners and heaters using large amounts of energy to maintain the desired temperature. Electric water heaters are also significant energy consumers, as they constantly keep water at high temperatures. Lighting accounts for a notable portion of electricity usage, especially if lights are on for most of the day. Additionally, appliances like televisions, cable boxes, and video game consoles contribute to energy waste due to standby power usage. Upgrading to energy-efficient appliances, such as smart fridges, and adopting energy-saving practices can help reduce electricity waste and lower utility bills.

What You'll Learn
Heating and cooling appliances
The energy consumption of heating and cooling appliances can be reduced by implementing certain measures. For example, good insulation, air tightness, and shading can improve the energy efficiency of these appliances. Regular cleaning and servicing of indoor air-conditioner units and filters are also important for maintaining energy efficiency. Each degree of extra heating or cooling can increase energy use by 5-10%, so adjusting the thermostat can make a significant difference.
In addition to adjusting the thermostat, there are other ways to reduce the energy consumption of heating and cooling appliances. For instance, using ceiling fans can help circulate air and reduce the need for air conditioning. Drawing curtains during warm, sunny days can keep the indoor temperature cooler, while opening them during winter can allow sunlight to provide free heating.
Another strategy is to utilise waste heat from electrical appliances. For example, running a computer or server can generate waste heat that can be used for space heating. However, it is important to note that this approach may not always be more energy-efficient, and it depends on factors such as the type of space heating system and the life of the appliance.
By following these suggestions, households can reduce the energy consumption of their heating and cooling appliances, leading to both environmental and financial benefits.

Electric water heaters
There are several ways to reduce energy consumption and save money with water heaters. Firstly, consider adjusting the temperature. Most water heaters are preset at 140°F, but this can be reduced to 120°F without noticing a significant difference. Lowering the temperature not only cuts costs but also reduces the risk of scalding and slows mineral buildup and corrosion in the heater and pipes.
Another way to conserve energy is by insulating the water heater tank. New water heaters come with built-in insulation, but older models can benefit from an insulating blanket, which can reduce heat loss and save money on energy bills. Additionally, consider adding insulation to the hot and cold water pipes connected to the unit to prevent heat loss and improve energy efficiency.
Installing a timer to turn off the heater during certain times, such as at night, is another effective strategy. This not only saves energy but also extends the lifespan of the unit. Reducing hot water usage can also help lower costs. Low-flow showerheads and faucet aerators are inexpensive and can significantly reduce hot water consumption without compromising on comfort.
Finally, regular maintenance is essential. Leaky faucets and dripping taps can waste gallons of water, impacting your water heating bill. Therefore, it is important to promptly repair any leaks and maintain your water heater to ensure it is running efficiently.

Lighting
To reduce electricity usage from lighting, consider the following:
- Turn off lights when leaving a room.
- Use smart lighting systems that allow you to control your lights remotely via your phone, or install motion-sensing switches that automatically turn off lights in empty rooms.
- Replace incandescent bulbs with LED bulbs. Incandescent bulbs use 90% of their energy as heat instead of light. LED bulbs, especially ENERGY STAR-rated products, use at least 75% less energy and last up to 25 times longer than incandescent bulbs. While LEDs may cost more upfront, they quickly pay for themselves in energy savings.
- Ensure that your lighting levels are not higher than necessary, and avoid light shining when and where it's not needed. Light pollution wastes energy and has economic and environmental consequences.
- Use dimmers, motion sensors, and timers to reduce average illumination levels and save even more energy.

Entertainment electronics
Televisions, in particular, can consume a notable amount of electricity. The average TV uses around 620,000 watt-hours annually, and this can vary depending on the model, size, and special features. Smart TVs with quick-start or instant-on modes, for example, stay in sleep mode when not in use, consuming a small amount of energy that can add up over time.
Other entertainment devices, such as cable boxes and video game consoles, also contribute to energy usage. Cable boxes, similar to TVs, can run in the background and rack up electricity usage over time. Video game consoles, while not always on, can also consume a significant amount of energy during use, especially if played for several hours a week.
To reduce energy consumption and save on electricity costs, there are a few strategies to consider. Firstly, unplugging entertainment devices when not in use can help eliminate vampire power. Additionally, adjusting settings on devices like smart TVs can make a difference; turning off quick-start or instant-on modes ensures the TV is fully shut down when not in use. Furthermore, installing smart outlets that automatically monitor usage and cut power to devices on standby can be beneficial.
While entertainment electronics can contribute to energy usage, other household items, such as heating and cooling appliances, electric water heaters, and lighting, often top the list of the most significant energy consumers. Nevertheless, by being mindful of the energy usage of entertainment electronics and implementing simple conservation strategies, individuals can play a role in reducing their environmental impact and lowering their electricity bills.

Old appliances
Older appliances are often less energy-efficient than newer models, and they can be a significant contributor to high electricity bills. Here are some insights into how old appliances waste electricity and some recommendations for reducing their impact:
Refrigerators and Freezers
Refrigerators are always running, and older models can be significant energy consumers. Fridges made before the 1960s are generally more efficient than newer ones because they lack additional power draws like ice makers and auto-defrosters, which use a heating element. However, newer refrigerators can be more efficient overall. For example, modern refrigerators can use 40% less energy than models from 2001, and they have a lower environmental impact when it comes to manufacturing and disposal.
Heating and Cooling Systems
Heating and cooling systems are some of the most significant energy consumers in a household, accounting for nearly half of a typical home's energy consumption. Older heating and cooling appliances, such as furnaces, can be particularly inefficient. Newer models can be up to 50% more efficient than units made in the 1970s and 20% to 40% more efficient than models from just a decade ago. Proper insulation and duct sealing can also help reduce energy waste in older heating and cooling systems.
Laundry Appliances
Older laundry appliances, including washing machines and clothes dryers, can be major energy wasters. New energy-efficient washers use a third of the energy and half the water used by older machines. They also reduce the workload on water heaters by using less hot water. Additionally, efficient washers have higher spin speeds, reducing drying times.
Vampire Appliances
Older appliances are more likely to be "vampire appliances," a term for devices that use electricity even when they are turned off or in standby mode. Examples include TVs, cable boxes, and video game consoles, which can use a significant amount of electricity over time, especially if left running 24/7.
To reduce the impact of old appliances:
- Unplug appliances when not in use.
- Install smart outlets that automatically cut power to devices on standby.
- Consider investing in newer, more energy-efficient models, especially for high-use appliances.
- Regularly service and maintain older appliances to ensure they operate efficiently.
- Be mindful of appliance features that draw extra power, such as ice makers and auto-defrosters in refrigerators.
