Less stupidly wasteful than plasma, still hungrier than CRT. I find it a 
bit of a scam that Energy Star ratings seem entirely self-referential - 
that is, it's possible for an LCD TV to get five stars, when it still 
uses more power than a CRT of the same time. But that's just me, I 
suppose ...

Agreed to all. Eaves design makes a huge difference as well.

In a chest freezer, the cold air stays put when you open it. In an 
upright, the cold air escapes. So a chest freezer of comparable size to 
an upright will use less electricity.

Efficiency is, after all, a function of all that goes on - including 
unnecessary waste of already-chilled air.


And a wonderful article I found on converting a chest freezer to a chest
