![]() ![]() These more environmentally friendly power options include solar energy, for example. You may be eligible for reduced bills if you opt for greener energy sources to power your home or business. The reality is that electrical power is becoming more expensive. In general, you’re likely to have seen your electricity bills increase over the last few years, no matter your power supplier. Your power supplier will calculate your energy consumption bills based on your usage data per day or per hour. The amount you pay for your energy usage in kWh will depend on your home or business power supplier. Of course, the same basic parameters apply for business premises, too, so it’s worthwhile considering how much electricity you’re using! How does your kWh energy usage translate to the amount on your bills? If the home runs on other sources of power supply, it will use around 2,800 kWh per year on average.Īs we can see, there’s a huge difference in average annual consumption depending on whether your home uses electrical energy for its heating and hot water. If the home is using other energy sources, it’s likely to use around 970 kWh a year on average.īy contrast, a larger home that is around 150 square metres will use around 23,500 kWh per year on average if it uses electrical energy for its heating and hot water systems. Figures on average electricity consumptionĪ 30 square metre studio that uses electric power for its heating and hot water supply will consume about 4,350 kWh of energy per year on average. An electric oven, for example, is “on” about 50 percent of the time when baking.Home electricity consumption: what is the average power usage?įirst, let’s put average electricity consumption into perspective. Thermostatically controlled appliances are not “on” 100 percent of the time. KWH used per month x Your cost per kWh = Operating cost per month Wattage of appliance ÷ 1,000 x Hours used per month = kWh per month Here’s how that figure is reached: Example: For example, an electric space heater which lists 1,300 as the wattage, costs 13¢ per hour to operate. You can use this figure to determine the cost of operation. It’s not very difficult if you have the correct information.Īll electrical appliances have the wattage listed somewhere on the appliance. Your individual appliances and use patterns may vary, so you may want to figure exactly what it costs to operate your specific appliance. The costs computed for use are based on the energy consumed for typical appliances and the average use of the appliances. Multiply the 180 kilowatt hours times 10 cents and you’ll find that it costs $18.00 to operate the space heater four a hours day for a month. Four times 1,500 gives us 6,000 watts per day and 180,000 watts in a 30-day month (180 kilowatt hours). Let’s say the heater is run four hours a day. A space heater may take 1,500 watts per hour. If each kilowatt costs 10 cents, the lights cost $2.00 for the month.Īppliances which produce heat take the most electricity. Multiply the 20 kilowatt hours times the cost per kilowatt hour. Multiply the 200 hours last month by the 100 watts and you have 20,000 watt hours, or 20 kilowatt hours. You can figure the cost per month for an appliance from its wattage.įor example, let’s say that all of the light bulbs in your house are 100 watts, and your family has had the lights on for a total of 200 hours last month. Compute your appliance costīills are figured on your use of kilowatt hours, which are 1,000 watt hours. The next area with the greatest potential for savings will be your hot water heater. In winter, heating will be over one half of the energy going into the home. When trying to conserve energy, concentrate on the areas of large usage. Or you may find that the cost of operating all those electrical appliances and heating your hot water is worth it. Once you have an idea how the electricity is being used, you may be able to figure out ways to cut back. The amount used also varies with the weather and the seasons. Your use may vary depending on your lifestyle, the size of your family and the size and age of your appliances. This graph shows how energy is used in the average home. When you receive your monthly electric bill, do you know where the power was used? ![]()
