I think I'm right but now I am second guessing myself.
If I have a 100 watt bulb that burns for 10 hours, I will use 1 kilowatt of electricty.
So if my electric costs approximately \$.10 per kilowatt, it costs me ten cents to burn the bulb for 10 hours.
TIA

1 kilowatt-hour

per kilowatt-hour

Math right, terminology wrong.

But in my defense I'll note that the two units are fundamentally different, not just "terminology" (another word for the same thing)...

Sounds right and that is around \$7.20 a month. It adds up pretty quickly when you have 7 bucks here and 7 bucks there..

Personally, I like Vista, but I probably won\'t use it. I like it

Good point. I really didn't consider that. I was just trying to show off Google's conversion features.

Well, they all kinda do.
Twenty-nine-plus minutes per month = about 6 hours per year and, in four years, that's about a full day, which is accounted for by a leap year.

It comes from leap year: 400 years (4800 months) have 97 leap years (every 4, except (divisible by 100 and not divisible by 400)) and 303 non-leap years. 303*365 + 97*366 = 146097 days, *24 = 3506328 hours. Divide by 4800 to get 730.485 hours/month.
Google's number may include leap seconds or other correction I didn't have above.
Of course, anything that requires evaluating the savings over a 400 year horizon just might turn out to not be cost effective :-)

I simply pointed out it isn't _any_ one month (and note the :) ).

Where? It doesn't seem to be above about \$.12 in the midwest according the the chart the other poster provided.
