hey everyone. Suppose i have 3 26 watt cfl lights and i run it 18/6 everyday, and $.14/KWH. How much is it going to cost me for 1 month.?
18 hours a day For 30 days X 3 26 watt cfls = 78 watts (.078 kwh) 78 watts over 18 hours = 1404 watts used each day (1.404 kwh) 1404 watts used each day for 30 days = 42,120 watts used per 30 day month (42.120 kwh) at $.14 an hour totaling $5.89 cents, more or less. Yeah, I'm baked enough to do the math for you.
