I'm curious if you mean the 15 cents per kwh estimate is too high or too low? It's a conservative average for me in upstate NY over the past ~15 years.

If you're using electric resistance heat, then I suppose a running computer is kind of like processing power plus "free" heat :)

Prices obviosly differ a whole lot depending on the country. My point was not absolute monetary savings, but energy saving.

My school physics tells me that nearly everything you do with electricity at home will heat your home. Doesn't matter whether it's the baking oven, the computer or the fridge. So if you heat using electricity and live in cold climate saving energy for computers or household appliances just moves the same consumption to heating.

The big exception is heating water. That energy is typically lost to the sewer.

As long as you pay the same electricity price for your computer as for your heating, it does not make a differencd whether that's 7 or 50 cent or the 15 you estimated.
