Energy...

When the city of Juneau, Alaska, experienced a severe energy shortage last month, local businesses quickly unplugged some of their most energy-dependant appliances: vending machines.

According to the U.S. government's ENERGY STAR program, the average vending machine costs a business $311 a year in electricity costs alone. But an ENERGY STAR-qualified vending machine costs half that -- $158 -- or less if includes software to further reduce energy use during non-peak times.

When you consider that the average business has several vending machines, you can see how costs can quickly spiral out of control.

There are several ways to green your vending machines, which will help you to save money and reduce greenhouse gas emissions. One way is to replace older vending machines with ENERGY STAR-rated models. Another is to invest in the VendingMiser from USA Technologies. These plug-and-play devices use passive infrared sensors to monitor their surroundings, turning vending machines off when no one is around. The also monitor vending machine temperatures, keeping drinks cool while using less energy. USA Technologies says their VendingMiser makes any vending machine as efficient as an ENERGY STAR device and can save a business up to $150 a year in energy costs, while also reducing annual maintenance costs by another $40-$80.

So the next time you see one of your employees carrying an ice-cold soda back to their desk, think about how much that can or bottle is costing you, and take a small step to protect the environment. Your bottom line will thank you.
