Today I was trying to find out which compact refrigerators are the most energy efficient. After some searching, I ended up at the Energy Star site, where they have a spreadsheet listing Energy Star fridges along with how much power they use and how big they are.
I took this spreadsheet and sorted it by kilowatt-hours (kWh), so the fridges at the top use the least energy. Surprisingly, the most efficient fridge listed is not a compact fridge but a decent sized model by Sun Frost. The two most efficient compact fridges were the Samsung SKR1373* and the MicroFridge MHRA-4E.
