My usage of stuff often correlates to the sun being in the sky; By hosting things at my house my power consumption roughly maps to my solar output.

I can also get away with no powered cooling for my gear. ie: I need cooling well before my gear does.

Well, that does make sense with your username....

(And it's been pointed out to me before that there's a "Zalman" company making computer cooling equipment! What a coincidence.)
