Ethanol
Ethanol fuel is most commonly
made from corn products, a renewable fuel source that can be grown
year after year. Today, Minnesota is home to 14 ethanol plants
producing more than 330 million gallons of ethanol per year. Ethanol
production supports our local agricultural economy while reducing
our dependency on foreign oil.
Although the concept of ethanol as a fuel began as early as the first Model T car, Americans did not begin using ethanol-blended gasoline until the late 1970s. Ethanol first penetrated the market with the introduction of "gasohol," which is gasoline blended with 10% ethanol. A more recent advance is gasoline blended with 85% ethanol, known as E85. The introduction of E85 has led to the development of Flexible Fuel vehicles (FFV). Virtually identical to regular gasoline vehicles in other respects, FFVs can operate solely on E85, unleaded gasoline, or a mixture of the two. This ability gives drivers the flexibility and convenience of refueling with either fuel.
E85 has many advantages. The fuel has been shown to reduce emissions of carbon monoxide, ozone-forming hydrocarbons, carbon dioxide (a contributor to global warming), and benzene - listed in the 1999 MPCA study as one of the air toxics of particular concern in Minnesota. Additionally, ethanol is a natural source of octane, replacing harmful chemicals typically used in gasoline. While E85 may result in small increases in formaldehyde emissions, overall the toxic potency is less than that of conventional gasoline.
Many governments have chosen to buy flexible fuel vehicles that can operate on E85. In 1999, in fact, the U.S. Postal Service purchased 21,000 FFVs for its neighborhood delivery vehicles - and more than 100 of these FFVs are used in Minnesota. Some state agencies are following this example. In 2000, Minnesota state agencies were using about 800 FFVs. In 2002, the Minnesota Department of Transportation is meeting federal requirements in this area: 75% of its new purchases of light duty trucks in the Metro and Duluth areas are FFVs. Today, nearly 100,000 FFVs are registered and driven statewide by Minnesotans, including government employees.
Hybrid Electric
Hybrid Electric Vehicles (HEVs) combine the advantages of
traditional, gasoline-fueled vehicles with those of electric
vehicles. With a propulsion system that has the range and power that
consumers demand, HEVs reduce air pollution and increase fuel
economy. Depending on technology development and consumer
preferences, many designs are possible.
Far from being a new concept, the hybrid electric vehicle was first patented in 1905. The patent called for an electric motor to augment a gasoline engine. By the time the patent was issued, three and half years later, the gasoline engine had gained momentum leaving this great innovation all but forgotten. Despite a flurry of activity in the mid-1970s due to the era's international oil crisis, HEVs lay dormant until recent federal mandates required the phased-in adoption of cleaner burning vehicles.
In 2002, the Minnesota Department of Transportation is in the process of purchasingThe act and the function of responsibility for the acquisition of equipment, materials, supplies, and services. In a narrow sense, the term describes the process of buying. In a broader sense, the term describes determining the need, selecting the supplier, arriving at a fair and reasonable price and terms, preparing the contract or purchase order, and following up to ensure timely delivery. and testing electric hybrid cars.

FFVs have been used in Illinois since 1992, according to the
state's fleet manager, Barbara Bonansinga. As of 1998, the department had
purchased nearly 600 FFVs, representing 19% of the passenger
vehicles in the state fleet. Based on vehicles driven
80,000 miles, the department has found that most repair
costs for FFVs are similar to those for conventional vehicles. The average
fuel efficiency for a conventional Taurus vehicle was 25.5 miles per
gallon while a Taurus FFV averaged 23.5 miles per gallon. To date,
the cars have received high marks for driving, engine-wear, and
maintenance and repair.
Hybrid Electric
The California Air Resources Board sets standards for low
emissions vehicles. Although specific to California, these standards
are used by other states to make vehicle comparisons. Passenger cars and light-duty trucks certified to
California's low-emission vehicle standards provide emissions
reductions when compared to the basic standard. See Figure
1 in Law & Guidelines.
Today, two mass-produced HEVs are sold in the United States: the Honda Insight and the Toyota Prius. Both vehicles meet the federal Ultra-Low-Emission standard. According to their manufacturers, these vehicles average between 60 and 70 miles per gallon and should not require additional maintenance or operational costs compared to a conventional vehicle.
The Honda Insight offers a 1.0 liter, 3 cylinder engine and the Toyota Prius a 1.5 liter, 4 cylinder engine. Both are augmented by a nickel-metal hydride battery. Each has a maximum speed of 100 mph (engine and motor combined), and an average fuel efficiency of 66 mpg (combined city/highway).

Hybrid Electric
As the first HEV to be sold domestically, the Honda Insight was
honored as the first car to receive the Sierra Club's Excellence in
Environmental Engineering Award in the organization's 108-year
history. For its hybrid passenger car, the Prius, Toyota Motor Corporation received the 1998 Global Climate
Protection Award from the U.S. Environmental Protection Agency - the
only car manufacturer among 19 companies receiving awards.
The big three American auto manufacturers - Ford, General Motors and Chrysler - have also designed HEVs rated at 80 miles per gallon that are expected to debut in 2003.
FFVs are sold at dealerships nationwide at prices similar to or lower than those of gasoline-only vehicles.
The price of E85 fuel compares favorably with that of regular unleaded gasoline. In general, throughout 2002, the price of E85 fuel ranged 15-25 cents less than 87-octane gasoline.
Hybrid Electric
Currently, HEVs are sold at prices similar to or slightly higher
than those of conventionally-fueled vehicles.
HEVs offer significant savings in fuel costs. According to a 1995 study by NEVCOR, based on a price of $1.50 per gallon of gasoline, hybrids fared better than conventional vehicles. Fuel expenses for hybrids are estimated to be 3.4 cents per mile, with all-electric vehicles at 3.6 cents per mile - each better than the 5 cents per mile for conventional gasoline-powered vehicles. As the price of gasoline increases, fuel savings will become even more significant.

Other Types of Vehicles
Refurbishing State Patrol Vehicles
A state contract was awarded in 1998 to refurbish and reuse
approximately 130 of the Minnesota State Patrol's 1995 Caprice
vehicles.
Refurbishing these vehicles allows the State Patrol to save money. Instead of paying over $20,000 for a new vehicle, a department can save approximately $7,000 and, in essence, receive a new car. The Caprices are retrofitted with new 350 LT1 engines and remanufactured transmissions, with a 50,000-mile, three-year warranty. Refurbishment includes complete inspection of brakes, suspension, drive train, interior lighting, the electrical system, and all parts for possible replacement.
As one of the State Patrol evaluators of this project, Corporal Brad Smith expressed his satisfaction with results:
"I now have 25,000 miles on my car since the refurbishing was completed. I must say I am very happy with the car. When I first got the car back, it drove and handled like a new one. . . The car has 105,000 miles on it now, and I feel very comfortable with the car at high speeds and during emergency operations. . . I have no doubt in my mind that even with 150,000 plus miles the performance will still be there."
The contract is available for any state or local government Chevrolet Caprice police automobile 1991 or newer. For more information regarding the vehicle contracts, contact the Department of Administration Help Line at 651/296-2600.
Electric Vehicles
Unlike hybrid electric vehicles (HEVs) that use both an electric motor and an internal combustion engine, electric vehicles (EVs) are solely powered by an electric motor. Typically, the EV's lead-acid or nickel-metal hydride batteries allow it to travel approximately 100 miles between recharges. Although the purchase price can be $30,000 to $40,000 higher than that of a conventional vehicle, the Electric Vehicle Association of the Americas (EVAA) cites the following benefits:
-
EVs produce little sound relative to an internal combustion engine.
-
Well-designed EVs travel at speeds equivalent to conventional vehicles and offer all the same safety and high-performance features.
-
The per-mile fuel cost of operating an EV can be less than one-third that of a gasoline-powered car. Lower routine maintenance costs are expected, as EVs have fewer moving parts than internal combustion engines and require neither tune-ups nor oil changes.
-
Refueling can be done easily and safely at home overnight, at work, or at public locations such as shopping centers where electric charging units have been installed.
-
Electric vehicles are today's zero-emission vehicles. For power plants using renewable energy sources like wind, solar, and hydropower, no air pollution at all is created.
-
EVs help lessen the country's dependence on imported petroleum.
