Appliances are essential for modern life, but they can also be a major contributor to energy consumption and costly electricity bills. Knowing how much power each of your household appliances consumes can help you identify the biggest offenders and make adjustments to reduce your energy costs.
In this article, we’ll provide an overview of the power consumption of household appliances so that you can better understand their impact on your electricity bill.
We’ll cover topics such as which types of appliances use the most energy, what factors affect appliance power usage, and tips for reducing appliance power consumption to save money and be more environmentally friendly.
Different Types of Household Appliances & Their Power Consumption
Following are the estimated power consumption of some common household appliances.
Refrigerators are energy-intensive, consuming up to 7% of a home’s total electricity usage. Refrigerators come in various sizes and have different power ratings, depending on the make and model. Depending on your needs, you can find a refrigerator that consumes anywhere from 350 watts/hour to 780 watts/hour.
Washing Machine And Dryers
Washing Machines and dryers consume around of the total energy used in the average home, depending on the model. Washing machines use between 400 to 1500 watts per hour. Similarly, clothes dryers range from about 1500 and above watts per hour, with most falling somewhere over 1800 watts per hour.
Dishwashers also require a considerable amount of energy to run efficiently. Standard dishwashers consume 1300 to 1500 watts; newer high-efficiency models range from 700 to 1,100 watts per cycle.
Televisions use an average of 180 watts per hour depending on size and type, a relatively low amount compared to other appliances but still worth considering when factoring energy consumption into your daily routine.
LCD or LED televisions tend to be more efficient than their older CRT counterparts, as well as plasma TVs, which generally require higher amounts of energy depending on the type of model.
Air conditioners are one of the most power-hungry appliances in the home due to their cooling capabilities requiring higher energy consumption levels.
The wattage needed for air conditioning units varies greatly depending on size and efficiency rating but can range anywhere from 800 to 3,500+ watts/hour, depending on the type of unit you have.
Central Air Conditioners use between 15 and 60 amps & 240 volts, while a Window AC unit commonly uses anywhere from 3 to 20 amps and 120 volts.
Water heaters are another common appliance in our homes that require large amounts of power to function properly—anywhere from 500 to 4,500+ watts/hour depending on tank size and insulation levels, amongst other factors like water temperature setting and recovery rate.
Ceiling fans are the most efficient appliances in the home regarding power consumption, consuming just 25-75 watts/hour.
Computers and laptops are essential technology in the modern household, and their power consumption is a crucial factor to consider. Computers and laptops can range from 40 watt-hours to 200 or more depending on the processor and graphics card installed, size, and other components. On average, most computers or laptops consume around 60-90 watt-hours.
Toasters are one of the most common kitchen appliances found in homes today, and they generally consume between 1,000 and 1,500 watts of power per hour. Toaster ovens require slightly more energy due to their size and extra features such as convection cooking or broiling.
Ovens are one of the most energy-intensive appliances in the home. Gas ovens typically consume around 300 watts per hour, while electric ovens can use between 1,000 to 3,000 watts per hour. Electric ovens with additional features such as convection cooking or broiling can use even more energy due to their size and power requirements.
Microwaves are one of the most common and convenient kitchen appliances found in most homes today. They provide an easy way to quickly heat up food and drinks with minimal effort and energy. On average, most microwaves consume between 700 and 1,200 watts of power per hour.
Vacuum cleaners are also quite common in the average home and consume around 500 to 1,000 watts per hour, depending on the model. Vacuums with additional features such as wet/dry cleaning capabilities or HEPA filtration require more power than traditional vacuums.
Hair dryers consume a considerable amount of power in order to quickly and efficiently dry hair. Most hair dryers range from 1,200 to 1,250 watts per hour, with professional models utilizing 2,000+ watts/per hour.
