You know that old freezer "Uncle Harry" gave you to use in the basement so you could save money by storing on-sale food items? Well, it costs more to run that freezer for a year than you'll ever see in returns on food savings. If you're looking to save energy, and money, it makes more sense to have only one, well running, efficient refrigerator/freezer.
If you have a step ladder that is tall enough so you can’t see the top when standing beside it, be extra cautious about tool placement. Leaving a tool like a hammer on top is easy to forget. When you move the ladder, it could slide off and drop on you. The best bet is to use a tool belt to carry unused tools, either strapped to your waist or tied around the upper part of the ladder.
