If you're paying 8 cents per KwH for electricity, more power to you. But no one else is.
I don't know, is there? The link you posted was for September.
What you're saying is also not true about rates. Utah, Wyoming, Arkansas, West Virginia all pay less. I do happen to live in one of the lowest priced states, though.

Its case by case. For me, I get lots of natural light and don't use much artificial light at night. I generally keep most of the house dark. I do see houses around me where they are lit up like an Xmas tree but for someone like me its not a good investment.
For my situation, its better to wait a couple of years for prices to drop. Another calculation folks are ignoring is sunk cost in bulbs I already have that are at 10%, 30, 50% of their life. Those recessed bulbs are like $9 a pop and in my kitchen alone I have 8. In my family room there are 9. Right there that's like $150/half-life average which is $75 I have to gain back for a true break even...
