 Plus, where is the PC power going?  It's going into heating the house.
 All PC's built for quite some time have the ability to power down the
disk, put the monitor on stdby, etc as well, so the real power can be
an order of magnitude less than the max rating of the power supply.  No
way that can come close to the savings of lowering the furnace
substantially in cold weather.
