I do have a refrigerator, but I rarely store items in it. The items, which I store in it can be also stored in a cold room (in the pantry) of the house. The house is also heated with gas. I do not have and I do not watch TV. I rarely listen (and sometimes transmit) to/on the radio, but that can also be used with a battery. If it would be necessary, I could buy a battery for it in the local market.
