British Thermal Unit (BTU): A BTU is a measurement of energy or heat.Kilowatt-hours are electricity consumption over time. Kilowatt-hours (kWh): kilowatt-hours are how your electric bill measures your energy usage.Watts are the rate of electricity consumption. Watts (W) and kilowatts (kW): multiplying volts x amps gets you watts (or wattage).Amps are the amount of electrons (which make up electricity) flowing through a circuit. Amps (A): amps (short for amperes) are a measure of electrical current.Voltage is the speed of electricity passing through a circuit. Volts (V): volts (short for voltage) are measures of electrical pressure differences.There are a lot of terms you can use to describe how electricity flows and is used by appliances. If you live in a warm climate and need to run your air conditioning often, you’ll probably use more electricity than someone who lives in a more moderate climate. Where you liveĮspecially for heating and cooling systems, your geographic location is a large factor in your overall home energy usage. More rooms mean more lightbulbs and appliances, plus a larger area to keep heated and cooled throughout the year. In general, larger homes use more electricity. How many starting watts does a certain appliance require? How many running watts? Additionally, using more efficient Energy Star appliances can reduce your overall usage, especially for more power-hungry items like refrigerators, air conditioners, and dryers. More appliances mean you’ll need more watts, but the type of appliances you have also impacts how much electricity you use. Total wattage depends on several factors, including the number and type of appliances in your home, how big your house is, and where you live. Factors that influence how many watts you need to run your houseĮlectricity usage varies greatly, and there’s no simple rule of thumb for how many watts of power a house might need. By the time you’re asleep, your home will likely be using the least amount of energy it has used all day. At night, you take a hot shower thanks to your electric water heater. Later in the day, maybe you put a load of laundry in and turn your stove or microwave oven on to make dinner. As the day progresses and the weather heats up, your air conditioning might kick in. Think about all the appliances you may use throughout the day: you wake up in the morning and turn on your coffee maker and toaster. Notably, the wattage requirement of your home is highly dependent on the time of day and where you live your power needs could be as high as several thousand watts at a certain point, and as low as a few hundred watts at another. That’s 29,130 watts (W) per day, which can be divided by 24 hours to get an average of 1,214 W to power a home throughout the day. The best way to save on electricity is to go solar – register on the EnergySage Marketplace today to compare your solar options.Īccording to the Energy Information Administration (EIA), the average American home uses an average of 10,632 kilowatt-hours (kWh) of electricity per year.The appliances that use the most electricity are central air conditioners, EV chargers, ovens, and clothes dryers.The actual amount of electricity it takes to run your home depends on what appliances you run, how efficient those appliances are, and the size of your home.On average, it takes about 1,214 watts to power a home in the U.S.average household electricity expenditure and average electricity demand per household have been added. collecting data more frequently (quarterly, rather than annually) to improve the quality and consistency of information. This has been incorporated into the residential electricity cost data. Some retailers have also provided revised data back to the year ended March 2002. residential costs back to the year ended March 2009 have been revised based on consistent information provided by all electricity retailers. In particular, the treatment of discounts is expected to be clearer and more consistent between retailers. The Ministry now provides more detailed guidance for retailers on what the sales data should and should not include. greater consistency of information between retailers. The Ministry has made the following improvements to the sales-based electricity price cost data in July 2014:
