There is a big problem with this test seeing as how it doesn't take
into account where you live. In CA energy bills are much higher, even
if personal usage is lower we get charged more for everything so if I
pay $30 a month on electricity then I am using less energy than
someone in the midwest who also pays $30. Not to mention I pa even if
I don't use any electricity for the connection fee. That's not fair
questioning. I feel cheated. This calculator needs to be shot.
