No, the natural gas water heaters in my home, my mother's home, my divorced father's home, my boyfriends's mother's home, and in the home of my only sibling living elsewhere from above, and in my church, all of those water heaters that I know do not use electricity for water heating.
What? Have you not heard of natural gas ovens? Among myself and family and close friends, I know of 5 gas ovens and 1 electric one.
So you are arguing on basis of choosing a TV of a kind that uses more electricity than is used by most chosen by our fellow Americans?
(Or what was your argument here, since what I responded to having to do with TV usage was snipped out?)
Even there, the ROI on investing in energy-efficient lighting is usually impressively good.
That sounds to me like you go to bed to sleep for the night by 9 PM. It does appear to me that an American needing to have only one light in the house to be on and only on for 5 minutes between 9 and 11 PM is even more uncommon than an American household that can halve its electric bill by replacing incandescents with CFLs.
I know of some CFLs that are good for porch lights. The Philips SL/O, or whatever they call them now and maybe now only available from Home Depot in 15 watt wattage, do well. My mother uses those for porch lights, and they usually last more than a year running all night every night and through many days.
