Ethanol Fleet Experiences
Small Idaho County Goes Big in Petroleum Reduction
Last Updated: April 07, 2011
With a population of about 200,000, Canyon County, Idaho, may not be very big. But its recent successes in reducing petroleum use are enormous. About two years ago, Canyon County Fleet Manager Mark Tolman puzzled over a problem shared by countless public officials throughout the country: How would he provide a high level of service to his community in the face of shrinking budgets?
Tolman worked with Treasure Valley Clean Cities to develop a strategy that made better use of his existing fleet resources while also embracing new technologies and fuels. He convened a "utilization team" that sought the input of vehicle drivers in every county department. He also purchased fleet-management software that allowed him to better track and scrutinize fuel use, vehicle utilization, idling time, and employee mileage reimbursements.
Armed with the new data, Tolman trimmed the county's fleet from 325 vehicles to its present 220. He developed a new replacement schedule that incorporated E85 and hybrid vehicles into the fleet wherever possible. He started filling tires with nitrogen. And the Fleet Department installed two new 12,000-gallon fuel tanks (one for gasoline, one for ethanol) and a blending dispenser that allows workers to specify the level of ethanol in the fuel they use.
Before Tolman's project began, he knew fuel was being wasted in idling patrol cars in the Sheriff's Department, but once he had the hard numbers in front of him, "It was just shocking," he says. Each patrol car was idling for up to five hours per day, using about one gallon of fuel per hour of idle time. Over the past year and a half, Canyon County fleet workers installed idle-reduction equipment on nearly all of the 65 patrol cars in the sheriff's department, eliminating 36 "ghost miles" and 100 pounds of carbon dioxide emissions per day for each car. "We're cutting our fuel use, and we're doing it safely-everything runs at peak performance. We're never going to leave our people hanging or compromise their safety," Tolman says.
Today, the Canyon County Fleet Department is eliminating an estimated 1.4 million pounds of carbon dioxide emissions every year and improving its vehicles' fuel economy by 4 mpg to 6 mpg.
"Using technologies that are already widely available, we realized immediate cost savings to Canyon County," he says. "We are maintaining a top-notch fleet, trimming our budget with minimal disruptions to ongoing operations, reducing our dependence on foreign oil, shrinking our environmental footprint, and serving as an example for other fleets."
Knoxville Utilities Board Uses a Variety of Alternative Fuels
Last Updated: April 04, 2011
The Knoxville Utilities Board in Tennessee has over 30 years of experience with alternative fuels with nearly 90% of their current vehicle fleet now using less gasoline and diesel fuel as a result. Besides vehicles that run on compressed natural gas and E85, KUB's fleet includes 14 hybrid electrics including bucket trucks used to repair power lines. Two off-road electric Tiger trucks have said "no" to petroleum, and many of their largest vehicles run on B5 biodiesel.
The utility is also involved with the EV Project, which will bring a charging network to the Knoxville, Chattanooga, and Nashville triangle region. Chris Wilson, fleet supervisor of KUB, says, "We want to get that corridor covered with electric charging stations where folks can get to and from those areas without having to use any type of fuel." KUB is displacing more than 46,000 gallons of petroleum a year using alternative fuels, demonstrating their strong commitment as an environmental steward for the residents of K-Town.
Boulder Wants to Add Electric Vehicles to Its Alternative Fuel Fleet
Last Updated: April 04, 2011
Boulder, Colorado, has made a city-wide commitment to alternative-fuel vehicles. Its lineup of flex-fuel police cars and light-duty pickups is a small sampling of the nearly 200 alt-fuel vehicles put into service since 2001. Along with E85, many of Boulder's maintenance trucks and street sweepers use B20 biodiesel. Propane is also part of the alt-fuel mix. Boulder also plans to convert 15 of their gas-electric hybrids to plug-in power. Charging stations will be installed around town with some of the current coming from solar energy.
Joe Castro, facilities and fleet manager of the City of Boulder Public Works, says, "We are looking at building a smarter electrical infrastructure with not only plug-in hybrids but also renewables, such as solar."
Nearly half of Boulder's fleet already is alt-fuel with a goal of 90%--a goal that will help ensure Boulder's Rocky Mountain view stays majestic.
Austin Municipal Fleet Runs on Alternative Fuel
Last Updated: March 21, 2011
The Austin, Texas, municipal fleet uses a wide array of alternative fuel vehicles including propane, biodiesel, hybrid electric, compressed natural gas, and E85. All play a part. Plus, EMS vehicles use solar panels to reduce wasteful idling. Austin's goal is a carbon-neutral city fleet by 2020. Almost 55% of their vehicles already use alt fuels with 30 new vehicles to go green next year.
"Anytime we can start using a renewable fuel source-an alternative fuel source that originates here in this country-then we're helping ourselves internationally in doing that. And we're helping the environment at the same time," says Austin Fleet Officer Gerry Calk. Austin also plans to add plug-in electric hybrids to its fleet and install EV charging stations around town to support them, making this once-oil-centric Texas capital among America's most alt-fuel-savvy cities.
Yellowstone Leads the Way to Alternative Fuel
Last Updated: March 07, 2011
The National Park Service is entrusted with preserving and showcasing America's natural wonders and historical landmarks, maintaining 392 national parks covering millions of acres of land and water in all parts of the country, and plays host to more than 275 million visitors every year. No other place on earth has this much natural diversity and spectacular scenery in one accessible place than America's first national park: Yellowstone.
So it's no surprise that this is one of the world's most popular tourist destinations. More than a million private vehicles and three million people traverse the park during the six months it's open every year. Yet the very act of admiring the scenery or stopping for one of Yellowstone's infamous wildlife jams-those daily backups caused by elk, bison, and bears blocking the road or just spotted nearby-is endangering the pristine environment that makes this place so special.
To combat the problem, the Park Service is committed to alternative fuel vehicles as a major part of their environmental stewardship program. In fact, a biodiesel-powered 1995 Dodge Ram pickup was the National Park Service's first alt-fuel vehicle, and it's still in service in Yellowstone with over 200,000 miles on its clock. Ask stakeholders in the Department of Energy's Clean Cities program: Yellowstone leads by example. All of their heavy vehicles run on biodiesel blends up to B40 in the summer. The park fleet also contains a number of flex-fuel E85 vehicles, advanced technology hybrids, and a few small electrics.
But park management is also looking to the past for inspiration. Jim Evanoff of the National Park Service explains, "Yellowstone had a very unique transportation operation prior to World War II, when we had a fleet of yellow buses. We had close to 400 of these old yellow buses that would transport people as they got off the trains in Gardiner and West Yellowstone and take them into the park. And most importantly, there was a driver that was very well educated and well versed in interpreting all the park's features to the visitors. After World War II, America fell in love with the private automobile and the station wagon, and nobody wanted to ride in these old yellow buses anymore, and they were slowly put out of service."
Amazingly, at its peak, Yellowstone was the second largest bus company in the nation behind Greyhound. Now, to reduce the volume of vehicles on the park's roads, Yellowstone has commissioned a small fleet of new biodiesel-powered yellow buses to use as employee shuttles and to serve as clean fuel ambassadors in nearby communities. The park has also acquired and refurbished eight of the original old yellow buses and put them back into service-once again giving guided tours in portions of the park.
Yellowstone is not as well suited to mass transit as other national parks, though. Parks with limited access or a single tourist attraction can more easily corral visitors' cars in one place and make use of shuttles. Glacier National Park's famous vintage red tour buses are still in daily use, plying visitors over the road to the sun. And they were retrofitted a number of years ago to run on clean propane while modern tour buses at Mammoth Cave National Park and others around the country are running on clean alternative fuels as well. Evanoff explains, "We're not just looking at alternative fuels but also looking at more green procurement. We're looking at water conservation opportunities, renewable energy such as from the sun or falling water.
Other park programs, like recycling and composting and a new partnership with Michelin to test low-rolling resistance tires, all tie together to reduce vehicle use, lower emissions, and save fuel. And the National Park Service hopes the influence of their good example extends beyond the park gates.
Mammoth Cave National Park is Committed to Alternative Fuel
Last Updated: December 01, 2010
In 1999, Mammoth Cave National Park in Kentucky made a commitment to use E85 ethanol in its small fleet of flex-fuel vehicles and installed their own refueling station. Today, more than a decade later, all of the park's 41 vehicles run on alternative fuels, including biodiesel, propane, and electricity.
The park has converted six school buses from gasoline to propane. They take nearly 175,000 visitors a year to cave entrances. Rangers use these gem all-electrics to patrol campgrounds and assists with parking.
For years, Melissa Howell from the Kentucky Clean Fuels Coalition has worked closely with the park to develop a strong alternative-fuel program?an effort that fits in perfectly with the National Park Service's mission to protect and preserve our country's most vital natural resources.
City of Ann Arbor Promotes Green Fleets Program
Last Updated: March 09, 2010
The City of Ann Arbor, Michigan, embarked on its Green Fleets Program in 2004 with the initial goal of reducing the municipal fleet's gas and diesel use by 10% before 2012. They achieved that in half the time and then set their sights higher: To use 30% renewable energy across all municipal operations by 2010, and they are meeting that goal, too.
"First of all, it's important for the City of Ann Arbor to green its fleet to help us fight climate change," says Andrew Brix of the Ann Arbor energy commission. "But the bigger impact is that we get to use fuels that are produced here in Michigan and in the U.S., and that keeps money in the local economy."
Ann Arbor's fleet uses a wide variety of clean alternative fuels, including E85, compressed natural gas in both light- and heavy-duty vehicles, and up to 50% blends of biodiesel. They are also field testing this hybrid electric lift truck and plan to buy two of them.
Ann Arbor is showing that even a small city fleet can make a big environmental statement. View the MotorWeek video of this story.
University of Oklahoma Adopts Variety of Alternative Fuels
Last Updated: November 10, 2009
The University of Oklahoma in Norman, Okla., has 160 vehicles that run on alternative fuels, including five low-speed electric vehicles. Two of the electric vehicles are used for on-campus mail delivery. OU also operates 43 electric utility vehicles and golf carts on campus sidewalks and paths that are used by maintenance and physical plant staff.
Beth Gatewood, OU assistant administrator of printing, mailing and document production, said the low-speed electric vehicles save the time and expense of refueling and are ready to go after recharging outside her building. "Besides being fun and quiet," Gatewood said, "we can get in all the small places on campus we need to squeeze through."
Central Oklahoma Clean Cities stakeholders since 1995, the University of Oklahoma Transportation and Parking Services, which includes Fleet Services operations and Cleveland Area Rapid Transit (CART), fuels 53 flex-fuel sedans and SUVs with E85, 41 heavy duty trucks and CART buses with B20, and 15 heavy duty and light-duty passenger vehicles and shuttle buses with CNG at its new Transportation Operations Center, a multi-fuel, state-of-the-art fueling, maintenance and operations facility. The center has four fast-fill CNG hoses at 3600 psi, and eight slow-fill CNG hoses in addition to four pumps for biodiesel and ethanol.
The university also has three hybrid electric passenger cars in its fleet that fuel at the facility which also dispenses gasoline and ultra low sulfur diesel.
At the official opening of the Transportation Operations Center in March 2009, OU President David Boren said the university is committed to the environment and the new Transportation Operations Center is a symbol of that commitment. Boren has made it university policy if an alternative fuel vehicle is available for the type of vehicle needed, the university will purchase the AFV.
OU Fleet Services plans to add five CNG buses to the CART fleet with 2009 federal stimulus money and will purchase and convert two new Chevrolet Impalas with assistance from an award from the Association of Central Oklahoma Governments' 2009 Public Fleet Conversion Grants program. ACOG's Public Fleet Conversion Grants¿ program is administered through its Clean Cities program office.
Alternative Fuels Are Key to Airport Transportation in Portland
Last Updated: August 24, 2009
The Portland International Airport (PDX) in Oregon has become a dedicated user of alternative fuel vehicles in almost every aspect of operation from baggage loading vehicles to shuttle buses, police vehicles, and street maintenance equipment. PDX began replacing conventional petroleum diesel buses with vehicles fueled with compressed natural gas (CNG) in 1997 and currently has 46 dedicated CNG vehicles including 26 shuttle buses, 6 Ford Crown Victorias, one Honda Civic, one F450 service truck, a forklift, 9 vans and two step vans. PDX also has two bi-fuel CNG/gasoline pickups and two vans. Propane vehicles include four forklifts and 1 small scrubber/sweeper. There are 15 flexible-fuel vehicles fueled with E85 and seven hybrid light-duty vehicles used for police activities.
Biodiesel also plays an important part in the alternative fuel plan. PDX has fueled its diesel vehicles with B20 since 2002 and currently operates 26 heavy-duty on-road vehicles including four buses, 19 trucks and three F450 service vehicles plus 27 additional pieces of off-road equipment.
PDX installed fueling infrastructure to meet its alternative fuel needs. The airport currently has CNG, LPG, and B20 fueling stations on the property, althought it cannot sell fuel to other fleets or the public because of access limitations. PDX is also looking to expand CNG availability by adding an additional fueling station or purchasing back-up components for its existing infrastructure.
Rick Elliott, aviation maintenance superintendent, points to lower emissions and longer operational life, which means more miles between rebuilds, as advantages to the alternative fuel fleet. "Whenever we look at purchasing a vehicle, our first question is 'Is it available in an alternate fuel?'" Elliott said. For more information, contact Rick Elliott at the Port of Portland.
University of Illinois-Chicago Fleet Invests in AFVs
Last Updated: June 01, 2009
Diversity on campus has a new meaning in Chicago. The University of Illinois-Chicago's (UIC) transportation system for innercampus and commuter transport includes a variety of alternative fuel vehicles (AFVs). The fleet includes 12 light-duty hybrids, 37 flexible fuel vehicles (FFVs), 26 vehicles that operate on B20, two compressed natural gas (CNG) cargo vans, and a CNG Crown Victoria. In addition, nine CNG Blue Bird buses transport an average of 2,000 people daily around the campus. All in all, AFVs represent 36% of their fleet.
With the help of two Congestion Mitigation and Air Quality (CMAQ) grants received through the efforts of the Chicago Area Clean Cities coalition, the university installed CNG infrastructure. "We now have two slow-fill dispensing units and we have added two quick-fill CNG units," says Pablo Acevedo, associate director of facilities management at UIC. The university's program extends its reach even farther by allowing vehicles owned by the City of Chicago to fill up at the UIC facility.
Acevedo explains that there are pluses and minuses to his CNG vehicles. "Parts and maintenance are more costly for the CNG vehicles than for regular diesel vehicles. It's also important to get the right kind of training for our mechanics who work on the CNG vehicles." On the plus side, the AFVs use less expensive fuel and reduce pollution caused by burning diesel.
The CNG and FFVs are purchased based on mandated levels dictated by the state and alternative fuel provider section of the Energy Policy Act of 1992. The CNG-powered vehicles were first purchased in 1997. "The decision back then was based on cost savings and environmental concerns," Acevedo says. "Those are the same reasons we continue to add CNG vehicles to our fleet."
There's always room for more advanced vehicles--and UIC is interested in the all-electric, commercial Ford Transit Connect van, which is expected to have a range of 100 miles per charge and a top speed of 70 miles per hour.
"UIC's commitment to its alternative fuel program and its involvement in the coalition make it an exemplary fleet in the Chicago area," says Chicago Clean Cities Coordinator Samantha Bingham. "We are happy to assist UIC as well as other coalition members with everything from technical assistance to identifying funding."
Enterprise Rent-A-Car Responds to Demand for Green Vehicles
Last Updated: April 25, 2008
In an effort to meet consumer demand for environmentally friendly vehicles, Enterprise Rent-A-Car is deploying its first group of "Green" branches in Atlanta and continues to expand its number of "E85/FlexFuel" branches nationally. Enterprise is a part of the Taylor family of companies, which includes National Car Rental and Alamo. The combined companies make up the world's largest vehicle fleet, which currently includes 4,000 hybrids, 73,000 flexible fuel vehicles, and 440,000 fuel-efficient vehicles.
At four Atlanta, Georgia, locations, hybrids and fuel-efficient vehicles will comprise approximately 60% of the company's "Green Branch" fleets. These fleets will offer approximately 30 percent hybrid gas/electric vehicles and 30 percent fuel-efficient vehicles that average a highway fuel efficiency rating of at least 28 mpg. "For the past 50 years, Enterprise Rent-A-Car has steadily grown its business by consistently talking with and listening to its customers," says Dan Miller, vice president and general manager for Enterprise in Atlanta. "With Atlanta ranking among the top cities in average commute times, customers of Enterprise's metro Atlanta branches have expressed great interest in renting environmentally friendly vehicles, and we are responding by concentrating the largest number of hybrid and fuel-efficient vehicles possible at these four area branches."
Enterprise also recently designated one of its Dallas-Fort Worth area rental locations as its first official "E85/FlexFuel Branch" in Texas. The location is at the Classic Chevrolet dealership located in Grapevine, Texas. Classic Chevrolet is also home to the nation's first dealership-owned public E85 pumps. Approximately 25% of the branch's vehicles will be General Motors flexible fuel vehicles (FFVs).
To build consumer awareness and increase the number of cars being fueled with E85, Enterprise is actively deploying the majority of its FFVs near E85 fueling stations. The Grapevine, Texas, E85/FlexFuel Branch joins similar Enterprise branches in Washington, D.C.; St. Louis, Missouri; Charlotte, North Carolina; Sioux Falls, South Dakota; and Cincinnati, Columbus: and Dayton, Ohio.
"Enterprise is committed to supporting new technologies and alternative fuels as they become commercially viable," says Miller. "We'll continue to make them more accessible to our customers."
Hoover Municipal Government Runs on Alternative Fuels
Last Updated: September 24, 2007
With a population of around 65,000, Hoover, Alabama, is the sixth largest city in the state. The City of Hoover currently operates 179 flex-fuel vehicles as well as 21 other light-duty vehicles, 60 medium- and heavy-duty trucks, two buses, two shuttles, and 96 off-road vehicles on B20, a blend of 20% biodiesel and 80% petroleum diesel. The city currently boasts that 80% of the fuel used by its fleet is alternative fuel.
Hoover's police force operates 130 of the flex-fuel vehicles, which are fueled 100% of the time on E85. The remaining 49 flex-fuel vehicles are used by the city's administative personnel. Hoover has also started a test program to use B20 in its fire trucks and plans to forward the results to the National Fire Protection Association.
Hoover may also be the first municipal government in the U.S. to manufacture its own B100 using waste vegetable oil collected from local restaurants. The city also plans to start home collection of waste vegetable oil by providing gallon jugs to homeowners who want to participate.
"The price of the alternative fuels is below the price of petroleum fuel. With our own B100 production, we might even turn a profit," says David Lindon, fleet management director for the City of Hoover. "The mayor and the city council are committed to clean fuel. It's the right thing to do for our energy security and it's cost effective."
For more information about the alternative fuel program in Hoover, Alabama, contact David Lindon, Fleet Management Director, City of Hoover.
Alabama Police Fleet Boasts 100% AFVs
Last Updated: September 21, 2007
The Hoover, Alabama, Police Department (HPD) operates 130 flex-fuel vehicles on E85 at all times. The vehicles are Chevrolet Tahoe police pursuit vehicles, making HPD the largest E85-fueled law enforcement fleet in the nation. The FFVs are fueled onsite at the Hoover Public Safety Facility, which has two dispensers with two hoses each. The facility, which was built in 2004 with a grant from Alabama Clean Fuels Coalition provided by Alabama Partners for Clean Air, is available for use by other public agencies.
Each HPD officer carries an E85 fueling card that is activated by a personal identification number. Information, such as miles between refueling and gallons of ethanol pumped, is collected with each swipe of a card. This information is used for analysis.
HPD serves a population of 65,000 in the sixth largest city in Alabama. The City of Hoover first became interested in FFVs for its police fleet in 2004 when the Central Alabama coalition arranged for the department to demo a Chevrolet Tahoe police vehicle. When considering the switch to the Chevrolet FFVs, the HPD was particularly impressed with the higher-octane levels ethanol offers.
The department didn't have any problems with driver acceptance. "By the time the vehicles arrived, many of the officers had test-driven the demo vehicle and had received training," according to David Lindon, the city's fleet management director.
The HPD estimates that it uses approximately 24,000 gallons of E85 a month. "The use of E85 is reducing air pollution and the city's dependency on foreign oil," says Hoover Mayor Tony Petelos. For more information about the Hoover, Alabama, police fleet, contact David Lindon, Fleet Management Director for the City of Hoover.
Iowa State Patrol Fuels with E85
Last Updated: August 27, 2007
In 2007, the Iowa State Patrol accepted delivery of the first 10 E85-compatible Ford Crown Victoria vehicles outfitted as patrol cars. An additional 119 E85 flexible-fuel vehicles are on order, and from this point forward, all Ford Crown Victorias ordered for the State Patrol will be E85 compatible. That means in just three years, the entire Iowa State Patrol will be able to run on the 85% corn-based fuel.
"Iowa is America's biofuels leader, producing more ethanol and biodiesel than any other state," says Governor Chester J. Culver. "We are the leaders in biofuels production and it is only fitting that our Iowa State Patrol cars run on clean-burning, Iowa-grown ethanol."
Department of Public Safety Commissioner Eugene T. Meyer agrees. "The addition of E85 compatible cars to our fleet and the use of Iowa grown ethanol demonstrate the department's commitment to a greater use of renewable energy."
For more information contact James J. Saunders at the Iowa Dept. of Public Safety.
