I can't recall seeing this tip anywhere, maybe I missed it...I use Rain-X interior glass anti-fog on all my interior glass, which allows me to use defrosting less or not at all depending on conditions. This certainly helps FE since defrosting involves either running the fan AND A/C compressor together, or running the electric defroster for the rear window which draws a lot of power. There is also a similar product called Never Fog.
