CASE STUDIES
UNC-Charlotte Greens Their Fleet: Over the past few years, Facilities Management at UNCC has developed and implemented an ambitious strategy to have a cleaner and greener fleet. The best example of this can be found in the 56 electric vehicles that are currently running on the campus, and received the 2008 Clean Cities award from the Centralina Clean Fuels Coalition.
Duke University: Since 2004, the entire bus fleet at Duke University has been running a 20 percent of biodiesel. Diesel vehicles using B20 produce 35 percent less particulate emissions. They also have longer engine life and lower maintenance costs. Environmental Alliance, an undergraduate environmental organization, authored a cost/benefit report, which led to a $28,000 grant from the Triangle Clean Cities Coalition to pilot test and begin using B20 (a 20 percent blend of biodiesel into low sulfur diesel).

East Carolina University using ethanol/gasoline mixture: ECU began using an E10 mixture (90 percent gasoline, 10 percentethanol) fuel mixture in May 2006. The university estimates its total fuel use to be 170,000 gallons annually. By this count, making this switch to E10 will save approximately 11,000 gallons of gasoline per year.

N.C. State University: In fiscal year 2003-2004, the University leased 293 vehicles from the state's Motor Fleet Management. 156 of these were flex fuel vehicles. The new fleet management software that N.C. State Fleet Services started using in late 2004 allows for tracking of vehicle maintenance and the type of fuel used, as well as determining miles per gallon for each vehicle and the fleet overall. This will allow for performance comparisons between flexible fuel vehicles, alternative fuel vehicles, and conventional vehicles.

N.C. Motor Fleet Management: The Motor Fleet Management Division has been doing its part to bring fuel-efficient and alternative fuel vehicles to the state’s fleet. Since 2000, Motor Fleet has been purchasing hybrid vehicles and now owns 116. Next year they intend to purchase nine new Ford Escape Hybrids. As of this year, there are 6118 vehicles in the fleet that can use ethanol fuels. These vehicles, called flex fuel vehicles because they can use regular gas or ethanol fuel blends, make up about twenty percent of the total fleet. However, only one percent of fuel use in 2005-06 was E85 fuel (the highest concentration of ethanol-gasoline blend). Thirty new E85 fueling stations are planned throughout the state to be in operation by 2010, bringing the total number to 40. The N.C. Alternative Fuels Consortium, a State Energy Office initiative, is dedicated to expanding E85 infrastructure for state fleets.
N.C. DOT Bike/Pedestrian Division: The Division of Bicycle and Pedestrian Transportation is working to make bicycling and walking a safe and effective form of transportation in communities throughout the state. In the spring of 2007, 16 municipalities were awarded funds under the Bicycle and Pedestrian Planning Grant Initiative. Cities and counties use funds for planning infrastructure developments to encourage biking and walking locally.
Alternative-Fuel Vehicles Contribute to a Bright Future: This 1997 case study highlights a demonstration project at Argonne National Laboratory that proves the value of gasoline substitutes. The project is managed by the National Renewable Energy Laboratory and it analyzes fuel economy, performance, safety, maintenance, emissions and costs of AFVs. Click here for the full case study.
