Electricity Costs: What Appliances Drain Your Wallet?

The cost of electricity has been steadily rising, and many homeowners are looking for ways to lower their electricity bills. The appliances that use the most electricity in a home are those that control the climate, such as air conditioning and heating systems, which can account for up to 46% of a home's energy consumption. Water heating is another major contributor to electricity costs, adding around 14% to energy bills. Other appliances that use a lot of electricity include washing machines, tumble dryers, ovens, and stoves. Lighting also uses a significant amount of electricity, especially if the lights are on for most of the day.

Heating and cooling appliances

Air conditioning units are among the most expensive appliances to run, with costs varying based on usage patterns and temperature settings. For example, during the summer, air conditioning can cost between $0.30 to $0.40 per hour, adding up to $100 to $150 to your energy bill. To reduce these costs, Ausgrid recommends setting the temperature between 23 and 26 degrees Celsius. Each degree below this range can increase running costs by up to 10%. Additionally, using a fan in conjunction with air conditioning can reduce energy usage by up to 70%.

Water heaters also contribute significantly to energy costs. On average, water heaters run for about three hours per day, totalling 13.5 kWh in 24 hours. The energy consumption of water heaters can vary depending on factors such as the maximum water temperature and the distance between the heater and the apartment unit.

Other heating appliances, such as room heaters and electric heaters, also consume a considerable amount of energy. Similarly, fans, including ceiling fans and pedestal fans, contribute to energy costs, albeit at a lower rate of around $0.02 per hour for ceiling fans.

To optimise energy usage and reduce costs, it is recommended to use energy-efficient appliances and manage temperature settings. Additionally, sealing doors and windows during extreme temperatures can help maintain the desired temperature and reduce the workload on heating and cooling appliances.

Kettles and ovens

Ovens, on the other hand, typically operate between 2000 and 5000 watts, with higher wattage ovens using more electricity. Oven size also matters, as larger ovens require more energy to heat due to their increased capacity. The cooking mode, duration, and temperature also impact energy consumption. Fan-assisted cooking is often the most energy-efficient mode as it circulates hot air, reducing cooking times. Batch cooking, limiting preheating, and utilising residual heat are also ways to reduce energy use.

Compared to other appliances, ovens generally use more electricity than kettles, but kettles are still one of the highest users of electricity in the home, especially if overfilled or reboiled regularly.

Computers and monitors

Laptops, in particular, are listed as one of the 30 most expensive electrical items to run in the home, costing 1p per hour to run on average. While this may not seem like a significant amount, the cost can add up over time if the laptop is left on for extended periods or not powered down properly.

To reduce electricity costs associated with computers and monitors, it is important to power down electronics fully when not in use, rather than leaving them in standby mode. Additionally, investing in energy-efficient models or upgrading hardware can also help to reduce energy consumption and lower electricity costs.

Lighting

Old-style incandescent lightbulbs are more expensive to run, costing about £0.02 per day or £7.30 per year. In comparison, LED lights are much cheaper, with an LED downlight costing only £0.012 in energy per day if used for 8 hours, or £4.15 per year.

Switching to LED light bulbs is a simple way to reduce energy costs. LED bulbs use significantly less energy than traditional incandescent bulbs, and the cost difference is substantial. For example, a halogen downlight, which is less energy-efficient than an LED bulb, will cost £0.12 per day or £43.20 per year.

While lighting may not be the biggest energy expense in a household, it is still important to be mindful of energy usage. Turning off lights when leaving a room and making use of natural light during the day can help reduce electricity costs. Additionally, investing in energy-efficient LED bulbs can provide significant savings over time.

Another way to save on lighting costs is to utilise smart lighting solutions. Smart bulbs can be programmed to turn off automatically when not in use, and some can even adjust their brightness based on the amount of natural light in a room. These features can help further reduce energy consumption and extend the lifespan of the bulbs.

Clothes dryers

The cost of running a dryer will depend on how often it is used, with more frequent use leading to higher electricity costs. Using a dryer three times a week will use about 468 kilowatt-hours of electricity per year, costing an average of $66.41. The time of day can also impact the cost, with some people taking advantage of free periods, usually after midnight, to avoid charges. However, even during free periods, dryers are still using electricity.

There are ways to reduce the electricity usage of clothes dryers. Firstly, choosing a dryer with a higher wattage that can dry clothes faster may be more efficient than a cheaper dryer with lower wattage that takes longer to dry the same amount of clothes. Additionally, using low heat settings and the cool-down cycle can help reduce electricity usage, and sensor drying is more efficient than timed drying. Fully loading the dryer can also maximise its efficiency, similar to a dishwasher.

Another way to reduce electricity costs is to invest in a dryer with an ENERGY STAR certification. These dryers are designed to be more energy-efficient and can use around 20% less electricity than a standard machine. They include features like advanced moisture sensors that minimise runtime. Solar panels can also be used to power clothes dryers, with 8-9 panels typically needed to power a 3,000-watt dryer.
