I seriously doubt that. "net of everything" would include HVAC. * In the winter, my computer means I run my space heater less by every watt it puts out. It's free. * In the summer, the costs are several times higher. Every watt put out by my computer means several watts of running the AC. It's actually a rather large difference. If I were in Alaska, computer power would be nearly free. If I were in Mexico, it'd be very, very expensive.
