How knowledgeable are you about how much electricity is really used by different appliances? Because – too many parents nag their children over things that are really quite negligible, while they don’t make other changes that would make much larger differences.
Electricity rates vary a lot – average in California, where I live, is about 16 cents per kwh, but in Washington State the average is under 8 cents per kwh.
Okay – so look at the reality. A 1,000 watt window air condition (a
medium size) uses 1 kwh in an hour. So it costs from 8 to 15 cents to run it for an hour or 80 cents to $1.50 to run it for ten hours.
A 100 watt lightbulb costs 1/10th of that – or .8 to 1.5 cents for an hour. TEN hours of leaving a 100 watt lightbulb on would cost 8 to 15 cents.
If you use compact fluorescent replacements they will cost about 1/4 of that — so about .2 to .4 cents for an hour or 2 to 4 cents for 10 hours.
So – switch to CF lighting – and figure even if he left lights on for the entire month, it would cost a total of about a dollar and a half up to maybe three dollars for the whole month, 24 hours per day.
Is it worth stressing and messing up your relationship over a light bulb?
Maybe you could go to this website – put in your appliances and figure out where you really could save enough money to make it
worthwhile to worry about it?
I know my husband sometimes gets on us about leaving lights on and I sometimes remind him that if he just turns them off when he notices it, that he might save a penny or two and he can also save a negative moment if he just does it without letting it annoy him (or us).
On the other hand, my husband earns most of the money that lets us live this amazing lifestyle and so I try to honor that by using the money carefully. So I’m not saying to encourage waste, I’m saying that you should know how much money you’re really talking about and decide whether it is really worth having hard feelings over it.
