New, efficient vending machines are available that can greatly reduce operating costs through the use of [http://en.wikipedia.org/wiki/Passive_infrared_sensor infrared motion sensors].  These sensors allow some of the machines functions to only work when a person is present in front of the sensor.  The compressors run only enough to maintain a suitable temperature throughout the workday while the lights and other components remain off in order to minimize overall energy consumption.  <ref> E Source Companies LLC (2009), ''Vending Machine Energy Savings'', http://www.mge.com/business/saving/madison/pa_50.html </ref>
