A roadmap for simultaneously developing the supply and demand for energy-efficient beverage vending machines
Refrigerated beverage vending machines (vending machines) present a previously untapped opportunity for significant energy savings. In the US there are about 2.5 million vending machines in the field and new machine sales exceed 250,000/year. Existing vending machines consume approximately 7.5 billion kWh/year and cost $600 million/year to power. Initial estimates suggest that approximately 3.5 kWh/day can be saved per machine through refrigeration and lighting energy efficiency improvements alone, most of which have already proven successful in other applications. Over the ten year machine life, the approximate per machine savings are 13,000 kWh, electric bill savings of $910, and carbon dioxide savings of almost 10 tons. Additional energy savings are achievable through energy management features that enable the lights to be turned off during off-peak times and the refrigeration system to cycle down when the machine is idle for extended periods. A coalition of interested parties formed to research this market and to develop a plan that would lead to the manufacture and sale of more energy efficient vending machines. A strategy to overcome market barriers and work with the four major stakeholders has been developed. This includes working with vending machine manufacturers to develop a performance based energy consumption specification compatible with the EPA/DOE Energy Star labeling efforts, and stimulating and demonstrating end-user demand by obtaining letters of support from high visibility institutions with a large number of vendors. This paper reports on progress to date.
