Thanks to [soon to be ex-] governor Gray Davis, my marginal cost for electricity is $0.20 per KWH. Where I work they don't want us to shut the PCs down at night because that is when they do the backups. If I could lower CPU peak power consumption by 40w, it would probably save 30w in average CPU power consumption. Inefficiencies in the power supply and regulation would increase that back to at least back to 40w.

40w*24*365*0.20/1000= $70/year. Remember, this is just the savings produced by buying a 60w CPU instead of a 100w CPU.

I suspect that commercial power rates are even higher than this.
