Are you using a calculator, or are you counting on your fingers?
A calculator.
$50 at 0.15 a KWH is 333.33333333 KWH
Divided by 30 is 11.111111 KWH a day
The only variable is what is your cost for power, more accurately what
is the incremental cost, minus the fixed charges that you pay anyway.
I bet it is less than 15 cents ... unless you are in California.
I pay 13 cents top line to bottom line and using less power would
actually make that more per KWH because the fixed charges stay the
same..
Heres my avg monthly kwh for the past 5 years 2078 2301 2326 2089 1784.
Have fun with those numbers.
