I'm paying 7.424p/kwh ($0.115) from EDF energy. There is a huge variation in tariff prices, even from the same supplier. You have to keep checking regularly to get the best deal.

Well, I have a sossaman rig and a core i7 920, and I plan to compare the PPD/$ electricity to see which is the most cost effective. If the Core i7 is effective enough, it could pay for itself with enough time.
This talk of replacing bulbs to save energy is ridiculous. The LEDs on the motherboards from all of your computers should be enough light:p:
My dad was complaining that I was using ~1300kWh one time. I don't use lights or the stove much, and I have no idea how much the water heater uses. I can only account for ~950kwh for all of the computers and related stuff.

I upgraded my main electrical circuit in my house last year from 60A to 200A. Well, you get a bigger meter from the electric company with this upgrade. Of course, the old meter had a low number, and the new meter had a MUCH larger number. When I got my electric bill the following month, instead of figuring out how much I really used, they took the value of the new meter and subtracted the old meter. So my electric bill was a "modest" $7,500 for using something like 77000 KwH. Then, because I was "late" because the computer billed it to me as part of the previous month, they tacked on a 1% fee, which was cheap! I have that bill framed. I did the math and even if I had used my max 200A current for the entire time that I was billed, I couldn't have used enough electricity to end up with a bill of that size. Lucky for me the electric company was able to fix the issue easily after just 3 phone calls and a threat to turn off my power unless I paid my bill current.
I've reposted my spreadsheet. It appears that I had an oopsy in the chart. If you changed the cost per KwH on the upgrade sheet it wouldn't be reflected in the prices. I tried to fix the old zip file, but the link keeps dishing out corrupt zip files. So here's the new zip with everything fixed.
