![]() electricity consumption increased in all but 11 years between 19, and 8 of the years with year-over-year decreases occurred after 2007. electricity consumption in 2022 was about 4.05 trillion kWh, the highest amount recorded and 14 times greater than electricity use in 1950. People use electricity for lighting, heating, cooling, and refrigeration and for operating appliances, computers, electronics, machinery, and public transportation systems. To compare between differently sized appliances, energy labels also now print suggested kWh usage per annum for each appliance.Electricity consumption in the United States was about 4 trillion kilowatthours (kWh) in 2022Įlectricity is an essential part of modern life and important to the U.S. Those rated A or above are the most efficient for their size. Instead, if you’re buying a new fridge or TV or other appliance, the best way to judge its energy efficiency is the label. In other words, don’t judge the energy efficiency of a device only by its given power rating, particularly if it is controlled with thermostat or operates on a timed cycle. But it completes its cycle quicker, so while it may use the same (or more) electricity per hour, it’s working for less time so uses less energy overall. An energy efficient dish washer, for example, may have a power rating of 2kW – the same (or higher) as a non-energy efficient one. This is what it costs to run the dehumidifier all day.īear in mind that sometimes a higher-wattage appliance will actually use less power overall than a lower-wattage one because it is well designed and does its job quicker. half a kilowatt every hour). Electricity now costs around 34p per unit, so multiply 12kWh by 34p and you get a grand total of 408p, or £4.08. So let’s say you have a 500W (0.5 kW) dehumidifier and you run it for a whole day (24 hours). You can work out how much an appliance costs to run by multiplying its wattage by the amount of time it’s on and then by the cost of electricity. So the daily cost of running a fridge or freezer is not 24 x the hourly cost.Įlectricity is sold by the kilowatt-hour (kWh) – usually referred to as ‘units’ on your electricity bill. ** Appliances like ovens, fridges and freezers turn themselves off when they reach the required temperature, so for some of the time that they are in use they won’t be using much or any electricity. This is because no one boils a kettle for an hour at a time, or puts on the fridge for 10 minutes. NB The costs below are based on a unit price for electricity of 34p per kWh (average direct debit rate) which is the price cap after 1 October 2022 as announced by the government on 12 September.įor some appliances we’ve only listed the cost for either an hour (column 2) or ten minutes (column 3). So cost of running, say, your microwave, could be a little more or a little less than the figure given. We’ve taken an average power rating for each appliance the actual power rating will depend on the size and specifications of the appliance. This table show what it costs to use a range of common appliances. And an iron will also use a lot of electricity because although it’s only used now and again, it requires a lot of power to make it hot. Of course, the amount of electricity it uses depends on how long it’s on for.Īn item like a fridge has a low wattage, but it will use a lot of electricity because it’s in use continually. This is the amount of electricity it needs in order to work. The largest proportion of most household’s electricity bill comes from running appliances like washing machines, dishwashers and electric showers.Įvery appliance has a power rating, usually given in watts (W) or kilowatts (kW) (1000W = 1kW). See table below for ratings for different appliances. So if you want to save electricity, there’s no point worrying about a digital clock or an electric razor since these use so little power you would hardly notice the difference. As a rule, those with moving parts or which produce heat use much more than those that produce light or sound. Some electrical appliances use a lot of electricity. And to do this, it helps to focus on the things that use the most, and so cost you most money … Recent steep increases in the cost of electricity mean that it’s more important than ever to find savings.
