In 2008, the average price of electricity in the United States was 9.74 cents per kWh. it is interesting to see that the most industrialized states like California and New York have the highest price of electricity. More recent data from 2010 is presented below for certain states for residential, commercial, and industrial electricity costs per kWh.
I live in Washington state & when my husband is home (he is a long haul driver) I am forever going around the house turning off lights that he leaves on for no reason. My question, of course, is how much is this costing us? A lot of times I don’t know that he has left a light on so therefore it could be left on for several hours. Can you please help me figure out how much we could be saving IF he would turn the lights OFF when he’s done with them. Thanks, Ellie
I can answer your question about how much the electricity costs if you can tell me how many Watts your lightbulbs are.
Lights are the least of your worries when it comes to your electric bill. The biggest users are heating/cooling, refrigerator and water heater.
Granted, turning lights off does save you a few bucks over a year and conserves energy too. Try doing an internet search “energy calculator” on your electric company website and you can calculate the cost of the lights. Or your electric company reps should be able to help you if you call.
