While we seem to focus so much attention on searching for and purchasing the most energy-efficient refrigerator and freezer, it turns out that how much food you store in your fridge or freezer has a significant impact on how energy-efficient they are. According to these green shopping tips at Ideal Bite, your fridge and freezer will function more efficiently when they are full, but not overstuffed.

So, here’s a thought: Next time you head out to do some grocery shopping, make it worth your while. Running in for just a few things multiple times a week ends up costing much more in the long run due to impulse purchases and wasted fuel. By planning meals, and shopping from a grocery list, you’ll conserve fuel, save money on groceries, and conserve energy. I guess the express lane isn’t the “easy out” I thought it was.
