Today, vending machines dispense just about everything imaginable, including gum, drinks, sandwiches, and electronics.
“Most vending machines, specifically refrigerated systems, waste loads of electricity each year. It is estimated that a conventional vending machine uses 3,000 to 4,000 kilowatt hours (kWh) per year. This is about a third of all the electricity the average US household uses in a year’s time. A large vending machine, and one that is placed outside in a warm, sunny climate, can use even more power.”
“…as of 2012, new refrigerated vending machines are required to use no more than 1,800 kWh per year. However, because vending machines can have a relatively long life span and are relatively inexpensive to repair, transfer to more energy-efficient systems may take years). Instead, they work 24 hours per day, seven days per week, whether needed or not.”
