A Practical Guide to Home Energy Use You can estimate your monthly electrical energy consumption. 8 KIUC CURRENTS By Anne Barnes Ever wonder how much it costs to do a load of laundry or spend all weekend watching football on television? You can figure that out with a formula that factors in the wattage of the electrical device, the amount of time it is used and KIUC’s cost of power. The basic unit of measure of electric power is the watt. Appliances and electrical devices are rated to use a specific number of watts. Usually, the wattage is stamped somewhere on the item. Usage, or the amount of energy consumed, is measured in watthours and represents the amount of power used over time, like over an hour. A 15watt compact fluorescent bulb left on Electric water heating can account for 40 percent to 50 percent of your monthly bill. • Solar water heating can provide up to 90 percent of your hot water needs. • A heat pump water heater can cut water heating costs by 30 percent. • Energywise rebates are available to help you install solar and heat pump water heaters in your home. • Renewable energy tax credits are available from the state of Hawai’i for heat pump and solar water heaters. Call the KIUC EnergyWise Program for rebate information and information to help answer your solar water heating questions. 808.246.8280 for 10 hours (15 times 10) uses 150 watthours. If you had 100 of these CFLs left on for the same 10 hours, the total energy consumed would be (15 times 10 times 100) 15,000 watthours, or 15 kilowatthours. Your utility bills are based on the total amount of energy you consume—the number of kilowatthours. If you use 1,000 watts of electricity in one hour, you have used one kWh. A residential guide to consumption is on page 9. To calculate on your own how much each electrical device costs to operate, start with the number of amps. Multiply that by the number of volts and then by the number of hours a day the item is used to get the total wattage. Divide that by 1,000 to get the daily wattage, then multiply by the number of days in the billing period the device is used. Multiply that number by the kWh charge to get the monthly cost. For example: If an appliance is rated at 5 amps, 120 volts and operates for 6 hours a day... To figure monthly usage: 5 X 120 = 600 watts X 6 hours = 3,600 kWh / 1,000 = 3.6 kWh per day X 30 days in the billing period = 108 kWh per month 108 X kWh charge = total monthly cost If the wattage is not listed on the appliance, you can estimate it by finding the current draw (in amperes) and multiplying that by the voltage used by the appliance. Most appliances in the United States use 120 volts. Larger appliances such as clothes dryers and electric cooktops use 240 volts. When measuring the current drawn by a motor, keep in mind the meter will show about three times the current in the first second the motor starts up than it will when it is running smoothly. Remember, too, that many appliances continue to draw a small amount of power when they are switched “off.” These “phantom loads” occur in VCRs, televisions, stereos, computers and kitchen appliances. Most phantom loads will increase the appliance’s energy consumption by a few watts per hour. We have provided the following chart to give you all the information you need to estimate the amount of energy used by various appliances around your home. These figures are approximate. Your own energy use may vary due to factors such as the age of your appliances and the differences between brands and styles. The estimated costs shown here are based on $0.42901 per kWh.
