The refrigerator is needed to keep food fresher for longer periods. This makes shopping and food preparation more convenient, and it does so at lower cost. The refrigerator is an almost mandatory home appliance. Perhaps the most valuable of any, including the stove or range. Previous to having electric refrigerators, people would buy blocks of ice for their refrigerators. Underground cellars were common for food storage before that, since the temperature would stay more or less constant. If there was a lake that would freeze over, ice would be cut in blocks and put into the cellars, lined with hay, which would help maintain the cool temperatures over the summer.
