JDS France, Technically speaking, assuming you don't have a refrigerator dedicated to the cuttings, storing the cuttings in the fridge consumes no electricity and may actually save a little bit. the cuttings act as a cold capacitor to keep the fridge from getting little less warm each time you open the door to get something. Of course either way the energy consumption is very small one way or another. But..... looking at the huge number of cuttings, I can understand why they are in the sand and not taking a whole shelve in the fridge
