Then keep in mind that a "30 W" computer will use much less than that in idle, where it'll be for 90+% of the time. Including auto-sleep, which Macs are good at, you'll be well below 10 W on average.

Absolutely, but replacing one energy-efficient sub-30 W CPU with another slightly more efficient CPU won't do huge things to the country's energy bill.
Less than the fridges switched on.
Here's a standard fridge Walmart sells for $449: http://www.danby.com/en/US/our_products/refrigeration/dff100... The EnergyGuide says it's estimated for 375.6 kWh yearly. That's an average of 42.9 W, including the times it's plugged in but idle.
