A brief description of the technology used:
Typical vending machines use upwards of $300 worth of electricity per year. Luther College installed Vending Misers, which are motion sensors that "see" when and if people are around. If there is no motion activity near the machine, they power-down the compressor, reducing electricity use on average by 40%, but still keep beverages at cool temperatures. Luther used money from the vending revenue account to pay for these sensors. All Luther beverage vending machines have Vending Misers installed. In addition, in February 2010, the 32 vending machines around campus were delamped in order to reduce "phantom" energy sources. Delamped the vending machines is equivalent to reducing Luther's carbon footprint by 56,448 pounds per year.
