All of those things you listed are used only intermittently which dramatically reduces their consumption. Many computers are on 24/7, especially Mac Minis and other things used for media servers.

Hmm... the graph shows 35 W. This standard full-size fridge http://www.danby.com/en/US/our_products/refrigeration/dff100... is rated for 375.6 kWh yearly, that is 42.9 W average. A mostly-idle Mac mini specced around 20-30 W would use well under 10 W on average.
