Each year, US vehicles use close to 3 billion gallons of fuel while at rest and idling. Large trucks alone consume more than 800 million gallons of fuel in the process of heating, cooling, and operating electrical equipment while idling at rest. One method of of reducing idle time for these large, heavy-duty trucks is to provide truck stop electrification, so that they may hook up and use power and other amentities provided by stations.

Light- and medium-duty vehicles also contribute to the overall consumption of fuel and production of emissions.

Reducing the amount of idling is one method of lessening overall petroleum consumption. In addition to saving fuel, idle reduction also reduces engine wear, emissions and noise.
