Idle Reduction

Core to Greater Lansing Area Clean Cities’ mission is an effort to reduce mid-Michigan’s petroleum consumption. Our aim is to decrease petroleum dependence and improve air quality a local level. We promote alternative fuel and vehicle usage, and fuel economy practices.

A big benefit to reducing petroleum consumption is the opportunity to reduce air pollution that results from using petroleum fuels. Engine idle reduction is an easy method for reducing both petroleum consumption and air pollution.

TAKING A SIMPLE STEP TOWARD PETROLEUM DISPLACEMENT

Idle reduction is typically used to describe technologies and practices that reduce the amount of time vehicles idle their engines. Heavy, light- and medium-duty vehicles and school buses can benefit from idle reduction strategies. Reducing idle time saves fuel, engine wear, and money while reducing emissions and noise.

About 500,000 long-haul trucks cross U.S. highways each day. Truckers are required to take a 10-hour rest after 11 hours of driving. As the trucks idle their engines during rest periods to provide heating, cooling, and electrical power and to keep the engine warm and the battery charged, they use approximately 838 million gallons of fuel per year.

A variety of technologies are employed to reduce this fuel use. Onboard equipment such as automatic engine stop-start controls and auxiliary power units can be used wherever the vehicle might be. Truck stop electrificationenables trucks to hook up to stations that provide power and other amenities.

A typical school bus burns approximately one-half gallon of diesel fuel for each hour it idles. Thus, if a company operates 50 buses and each bus reduces its idling time by 30 minutes per day, the company would save $2,250 per school year in fuel costs.

Additional strategies are available for light- and medium-duty vehicles and school buses. When the idling of these vehicles is added to that of the heavy-duty trucks discussed above, estimates of annual fuel use due to idling approach 3 billion gallons.
