Okay, I have heard that nomenclature of Kilowatthours enough times and it still makes no sense to me. Watts are watts, but nevertheless, I should get used to it. Thanks for clearing it up for me anyway, I really do appreciate it. I enjoy my independence from fossil fuels as much as possible, which is priceless to me. The 12 cents per kilowatt hour comes with too many strings for me and since I designed and installed my own system, it paid off about 18 years ago. Of course I do have the most expensive 12VDC ref/freezer made.
