top household energy users

Heating elements, air conditioners, natural gas and propane-fueled lights, outdoor grills, and backup electricity generators are among the top household energy users. These appliances are not the most energy-intensive. Other devices such as computers and televisions also consume energy.


Electricity is used to power large appliances like refrigerators, freezers, and other home appliances. A 1,000-watt appliance could use up to one kilowatthour of power if left on for at least an hour. Thankfully, appliances have become increasingly energy efficient over the past 30 years.

Electric bills are based on kilowatt hours (kWh), a unit of electricity that is equivalent to a thousand Watts (W). This means that powering a typical refrigerator for a day can consume up to four kWh of electricity. Refrigerators are among the most energy-intensive household appliances. An energy meter can be used to determine how much your fridge consumes.

You can also check the sticker inside your refrigerator to see how much power it uses. The energy usage sticker should indicate how many watts were used in each hour of operation. Most refrigerators consume between 300 and 800 watts. A solar panel producing 350 W should be capable of providing enough electricity to power one to three refrigerators. Your fridge’s electricity usage may fluctuate over the course of the day. It is important to select a system that can handle peak usage.

Washing machines, dishwashers, and stoves consume 5% of the home’s energy. Keeping these appliances in optimum condition will help you conserve energy and cut back your monthly bill. Don’t overload your washer and dryer. Also, don’t leave the door unlocked when drying clothes. This can cause a loss of cool air. It is a good idea to use your clothes dryer as sparingly as possible and to dry clothes on the line as much as possible. This will reduce energy consumption.

Air conditioners

ACs account for approximately 10% of global electricity consumption in buildings and are the largest energy users in homes. Air conditioning is an increasing global problem, particularly in hotter countries where incomes are higher and living standards are better. The global market for air conditioners will reach 5.6 billion units by 2050, an increase of 1.6 billion in today’s numbers. This means that 10 new air conditioners are sold each second.

According to the U.S. Energy Information Administration’s Residential Energy Consumption Survey 88% of American households use air conditioners. Of these, two-thirds use a central AC or heat pump. The South and Midwest have the highest proportions of households using air conditioners. ACs were used less often in households in the Pacific and other regions with marine climates.

Air conditioners are one of the most expensive household energy consumers. However, there are many ways to reduce their energy consumption and save money. You can reduce your energy consumption by purchasing energy-efficient models that have higher energy star ratings. Another option is to switch to alternative cooling systems. These alternative cooling systems can be more efficient, but they are also cheaper and easier to use.

If you are thinking about buying an air conditioner, make sure to look for the EnergyGuide label. This label is required for central air conditioners as well as room air conditioners. It packs a lot into a small space. The label shows the type of air conditioner, key features, and the manufacturer. It also lists the expected annual cost for running the air conditioner.

An average household air conditioner uses approximately 3500 watts per hour. Even a ‘fan-only’ mode will use 750 watts.

Plasma screens

A plasma screen requires a lot of energy. It can consume four-times the electricity of an older cathode radiation tube model. Many environmental activists see this as a major contributor to the energy crisis. They are encouraging people to adopt other energy-efficient technologies in order to reduce their homes’ energy consumption.

Plasma screens use energy due to the use of ionization. This is the process of converting light into images. The resulting light can be emitted in a variety colors. Each pixel is made up of three subpixels. Each subpixel contains a different colored color phosphor. These three cells make up the overall color of a pixel. Pulse-width modification (PWM) is a method that controls the brightness on a plasma screen. It changes the frequency at which current passes through the cells. This technique can create billions more colors.

The size of the plasma screen and its resolution affect the energy consumption. Most plasma screens use between 250 and 400 watts depending upon their resolution and dimensions. It is a good idea to use a power meter for monitoring electricity consumption. These devices are inexpensive and allow users to calculate how much electricity each device uses.

A plasma screen uses a lot more electricity than other household appliances, making it one of the biggest energy consumers. LED TVs offer a great alternative for people who are concerned about energy consumption. These televisions are thinner and less expensive than regular LCD TVs. They also use less electricity than CCFL TVs.

Washing machines

A washing machine consumes around 14 percent of the energy required to run a typical home. This is due to the heat used during the wash cycle. A 7kg washing machine will run you between PS25 and PS35 per annum. You can save money by using your washing machine wisely and investing in an energy efficient model. This isn’t the only way to save money on energy bills.

The average washing machine consumes approximately 400 to 1300 W per hour. This varies depending on the brand and load cycle. A model that is ENERGY STAR(r), certified will use 25% less energy than a regular washer. A washing cycle will take between 50-60 minutes. An average family washes about 300 loads of laundry per year.

Manufacturers are making washing machines more water-efficient and energy-efficient as part their quest to reduce energy consumption. Some models have detergent dispensers that can hold enough detergent to clean multiple loads. Other features include pre-programmed wash cycle that target specific stains as well as self cleaning cycles that thoroughly clean the inside of the washing machine.


Computers are among the biggest energy consumers in a household. According to an Energy Saving Trust study computer usage can account for up to 8 percent of household electricity. They also account for more than a quarter of all power used by consumer electronics. A typical computer uses approximately 35 pounds of electricity per annum, which equals roughly $50 in the US. Despite being smaller, computers use six times as much energy as laptops.

Other household energy users include ovens and stoves. These can be reduced by changing how you cook and cleaning your appliances. Computers account to one percent of household energy usage. To reduce your energy consumption, make sure you turn off your computers at night. There are also energy-efficient computers available.

A computer can consume approximately 3.5 kWh per week. This amounts to 15.2 kWh per month, or 182.5 kWh per year. The ENERGY STAR label on your computer is your guide to buying a model that is energy efficient. Power management features should be enabled, too. You can also check your Enervee score and see which computers are the most efficient.

A Kill-A-Watt Meter, which measures the electricity consumed by your computer, is another way to reduce household electricity costs. This device can measure electricity usage for any electrical device in the home, including your PC. It also measures the power usage of your surge protector.
