Drivers of hybrid and electric vehicles are accustomed to a feature called “start-stop” that saves fuel by turning the vehicle off when you’re stopped (e.g., waiting in traffic) and restarting it when you’re ready to move. However, if you want a new, conventional automobile or light-duty truck, you might consider buying one that uses the same technology. You can now find it in a range of American automobiles, including Cadillac CT6s, Chevy Malibus, Ford Fusions, and Ford F-150 trucks.
Start-stop (also known as auto start, idle stop, auto start-stop, start/stop, or mild hybrid) technology senses when your foot is on the brake for a predetermined period of time and shuts off the engine. All your auxiliaries remain on while start-stop is engaged. When you release the brake, the engine seamlessly starts up again. The technology underlying start-stop includes a heavy-duty starter that can endure 300,000 cycles instead of 30,000 cycles found in most vehicles.
Europeans have long used this technology, as their fuel prices are as much as three times higher than ours. In addition, start-stop engineering is less complicated for manual-transmission vehicles, which are more common in Europe than here in the States. Finally, current U.S. Environmental Protection Agency (EPA) fuel-economy test procedures don’t account for much simulated idling, so start-stop–associated savings may not even show up on the label of the new car, although this may change in the near future.
I recently took a few test drives of both American- and German-made automobiles equipped with start-stop. Each of the vehicles had an indicator similar to the one below to show when the feature was in use.

At first, the silence and lack of vibration at traffic lights were quite noticeable, but it didn’t take long to adjust to the quiet. Then, in the instant that it took for me to move my foot from the brake to the accelerator, the engine came back to life. I was expecting this experience, but if I hadn’t known about it, I would have been quite disconcerted. Automobile manufacturers do allow the start-stop feature to be turned completely turned off.
So how much fuel can you save by having this technology in your car or light truck? To quote EPA, “Your mileage may vary,” and savings depend on traffic and driving style. Fuel savings probably range from about 3% to more than 10% for stop-and-go city traffic. However, your driving habits strongly influence your actual fuel economy.
The Propane Education & Research Council donated $10,000 to Boston Public Schools to recognize its effort to improve students' health, safety, and education. The school district adopted Boston's first propane autogas powered bus fleet, adding 86 Blue Bird Vision Propane buses. These alt fuel buses will save the district up to $1,000 per bus annually and significantly reduce its diesel consumption.
PERC partnered with former first daughter and teacher Jenna Bush Hager and AdoptAClassroom.org to present the middle school's teachers at Lilla G. Fredereick Middle School with the money for classroom supplies, books, and outdoor equipment. This is a part of PERC's new campaign to educate consumers about the benefits of transition away from diesel to clean, domestic propane autogas.
"It's clear when you talk to school administrators and transportation departments that they are saving more than just dollars and cents by going with propane buses," said Bush Hager. "The switch is improving their school as a whole and giving them the opportunity to invest in more teachers or school programs."
Donations like this from PERC are wise decisions by school districts to choose a more cost-effective domestic fuel option like autogas will help put money back where it belongs - in the classroom and U.S. economy.
Question of the Month: What is renewable natural gas (RNG) and can it be used to fuel vehicles?
RNG is pipeline-quality natural gas made by collecting and purifying biogas, the methane produced from decomposing organic matter. Biogas can be collected from sources such as landfills, livestock operations, wastewater treatement plants, food manufacturing and wholesalers, supermarkets, restaurants, and hospitals. Once purified to remove contaminants and increase its heat content, the gas is called RNG and is a "drop-in" fuel that can be transported with conventional natural gas in pipelines, dispensed at the same fueling stations, stored in the same storage tanks, and used in natural gas vehicles without any engine modifications.
Despite its advantages, there are only 60 operational RNG production facilities in the United States. Many more us the biogas to generate electricity. This is due to federal and state programs, such as the federal Investment Tax Credit and state renewable portfolio standards, whic incentivize the use of biogas for power generation rather than for vehicle fuel.
The purification process fo rbiogas is called condition or upgrading, and it involves removing water, carbon dioxide, hydrogen sulfide, and various contaminants and trace elements. From there, RNG can be compressed to make renewable compressed natural gas (R-CNG) or super-cooled to make renewable liquefied natural gas (R-LNG).
RNG is produced from feedstocks that come from a wide range of industrial sectors, many of which already collect and process biomass as part of their daily operations:
- Landfills: Landfill gas (LFG) is collected from decomposing waste in landfills. According to the U.S. Environmental Protection Agency (EPA), landfills are the third larges source of human-related methan emissions in the United States. Landfills account for 70% of the operational RNG projects in the United States. One of the largest LFG-to-vehicle fuel projects is Waste Management's Altamont Landfill near Livermore, California. This project prudces up to 13,000 gallons of R-LNG each day to fuel 300 refuse trucks.
- Livestock Operations: Animal manure can be collected and taken to an anaerobic digester for RNG production. A few farms across the country have started to use biogas to produce RNG vehicle fuel, including Hilarides Dairy in California and Fair Oaks Dairy in Indiana.
- Wastewater Treatment Plants: Approximately 9% of th emore than 16,000 wastewater treatment plants in the United States use anaerobic digestion to produce biogas. The Janesville Wastewater Treatment Plant in Wisconsin is an example of a plant that uses biogas to produce RNG for use in vehicles.
- Other Biomass Sources: RNG can also be produced from lignocellulosic material, such as crop residues and dedicated energy crops, through thermochemical conversion, co-digestion, and dry fermentation. These technologies are being used in Europe, but have limited applications in the United States. RNG also can be produced from food waste, either alone or in conjunction with biosolids from livestock operations or wastewater treatment plants. CleanWorld Partners' Sacramento BioDigester and quasar's Central Ohio BioEnergy project convert food waste to RNG for vehicle fueling.
RNG qualifies as a cellulosic biofuel under the EPA's Renewable Fuel Standard (RFS2) program. In fact, RNG accounted for more than 50 million renewable identification numbers (RINs) in 2014 - 98% of all cellulosic biofuel RINs. According to organizations that track biofuels market data, cellulosic biofuel RINs were valued at $0.70 - 0.85 per diesel gallon equivalent in 2014; this value is expected to increase in the future.
Like conventional natrual gas, RNG can be produced domestically and can displace the petroleum currently being imported for transportation use. However, RNG offers some additional benefits. RNG has practically a net zero carbon impact. On a lifecycle basis, RNG accounts for fewer greenhouse gas (GHG) emissions than most currently available motor fuels. RNG can reduce GHG emissions by 95% compared to conventional gasoline and diesel fuel. This is partially because capturing biogas from landfills and livestock operations can reduce GHG emissions by preventing methane releases that were occurring into the atmosphere. Additionally, RNG produced through anaerobic digestion eliminates odors and results in nutrient-rich liquid fertilizer as a by-product. Also, biogas feedstocks are plentiful, so RNG could make use of the 450 million pounds of municipal solid waste dumped in landfills, 160 billion pounds of food waste generated, or the 500 million tons of animal waste produced each year.
Like conventional natural gas, the main barriers to RNG are lack of vehicle availability and fueling infrastructure, though efforts are underway to address both of these obstacles. However, RNG production costs exceed those for conventional natural gas, especially for small-scale operations. Small-scale RNG prodcution can cost around $5.50 - $9 per million British thermal units compared to $4.50 for conventional natural gas. Additional financing and incentive opportunities, as well as state renewable portfolio standards that encourage the investment in biogas for vehicle fuel production, may spur additional production.
U.S. Gain, the compressed natural gas (CNG) division of U.S. Venture, has opened its third of five CNG stations the company is building in partnership with North American carrier C.A.T. The new GAIN Clean Fuel station, located at 4250 Trailer Dr. in Charlotte, N.C., will support C.A.T.'s growing fleet of CNG trucks and will also be open to the public.
"We're proud to be leading the industry in creating sustainable transport," says C.A.T. President Daniel Goyette. "We've made an investment in our future with the conversion of our fleet to CNG. It's been a very positive move by helping us become more environmentally friendy and creating fuel price stability. We couldn't be happier with our partnership to make this facility a reality."
C.A.T., which operates over 300 tractors, announced a deal last year to lease 100 cNG trucks from Ryder System Inc.
The first GAIN Clean Fuel station under partnership with C.A.T. opened in Mississauga, Ontario, and the second in Coteau-du-Lac, Quebec. The other two locations include Laredo, Texas, and Scranton, Pennsylvania. These stations are finishing up on construction and are expected to open soon.
"We're thrilled to have another C.A.T. station open for business," says GAIN Clean Fuel General Manager Bill Renz. "This is a heavily traveled trucking corridor, and we look forward to serving not only C.A.T., but other carriers seeking to take advantage of the benefits."

Detroit Public Schools students are riding to and from school in cleaner-operating buses fueled by propane autogas. The 35 alternative-fueled Blue Bird Vision Propane buses lower costs while improving the environment by reducing Detroit’s carbon footprint.
This is the largest fleet of propane autogas school buses in the state of Michigan.
“The use of propane autogas school buses is a step in the right direction to significantly decrease vehicle emissions and improve the air quality for our students. This also provides opportunities for students and the community to observe and learn first-hand about alternative transportation technologies,” said James Minnick, executive director of DPS Office of Student Transportation. “This environmentally friendly green initiative has also resulted in having a bus fleet that is 30 percent brand new.”
ABC Student Transportation, Detroit Public Schools’ transportation provider, chose buses fueled by propane autogas because of the buses’ advanced technology, environmental benefits, and fuel and maintenance cost reductions, according to ABC Student Transportation president Charlie Grant.
The bus fleet will emit 12,445 fewer pounds of nitrogen oxide and 111 less pounds of particulate matter each year compared with the diesel buses they are replacing. Propane autogas also reduces hydrocarbon emissions and virtually eliminates particulate matter, when compared with conventionally fueled school buses.
Historically, propane autogas costs about 50 percent less than diesel per gallon and reduces maintenance costs due to its clean-operating properties. Currently, ABC pays 74 cents per gallon for propane autogas compared with around $3.00 per gallon for diesel.
Propane autogas is the most commonly used alternative fuel in the nation and worldwide. Vehicles fueled by autogas comply with the same safety standards as their conventionally fueled counterparts.
Question of the Month: How can I improve my gas mileage while driving this winter?
Whether taking that long-awaited ski trip or just commuting to work in the frigid weather, there are several things you can do to improve your fuel economy and save money in the wintertime.
Why You Get Worse Gas Mileage When It's Cold
Cold weather and winter driving conditions can reduce your fuel economy significantly. On particularly chilly days, when temperatures drop to 20°F or lower, you can expect to see up to a 12% hit on your fuel economy for short city trips. During very quick trips—traveling only three to four miles—your fuel economy could dip even lower (as much as 22%)!
This reduction in fuel economy is due to several factors. First of all, cold temperatures increase the time it takes your vehicle to warm the cabin, engine, drive-line fluids, and other components up to fuel-efficient operating temperatures. Cold fluids increase the friction on your engine and transmission, which can reduce fuel economy.
Let’s take a moment to address one of the main myths about driving in cold weather:
- Myth: To warm up your engine and vehicle cabin in the wintertime, you should let the engine run for several minutes before driving.
- Truth: Most manufacturers recommend driving off gently after about 30 seconds of idling. In fact, the engine will warm up faster when driving. Idling can use a quarter to half a gallon of fuel per hour, and even more fuel if the engine is cold or accessories like seat heaters are on.
Also keep in mind that winter gasoline blends in cold climates have slightly less energy per gallon than summer blends. This is because refineries alter the chemical makeup of gasoline to allow it to evaporate more easily in low temperatures, ensuring proper engine operation.
Aerodynamic drag is another consideration. In simple terms, cold air is denser than warm air, so when temperatures drop, wind resistance increases slightly. This requires a little more power from your engine to drive at a given speed. The effects of aerodynamic drag on fuel economy are most significant at highway speeds.
Winter Fuel-Saving Tips
The following tips can help you warm your car (and fingers!) more efficiently and improve your fuel economy in the winter:
• Park in a warmer place like a garage that traps heat to keep the initial temperature of your engine and cabin higher than it would be outside in the elements.
• Avoid idling to warm up the engine and cabin. See more information above.
• Avoid using seat warmers more than necessary, as they require additional power.
• Plug-in electric vehicle (PEV) owners: Pre-heat your vehicle while still plugged in. Since PEVs use battery power to provide heat to the cabin, cabin and seat heaters can drain the vehicle’s battery and reduce the overall range. If you need to warm up quickly, warm the vehicle while it’s still charging.
• PEV owners: Use seat heaters instead of the cabin heater when able. Using seat heaters instead of the cabin heater can save energy. Seat heaters use less energy than cabin heaters and can often be more efficient at warming you up quickly in the winter.
• Read the owner’s manual for detailed information on how your vehicle’s cabin and seat heaters work and how to use them efficiently.

The DOT is offering $22.5 million in grants in the latest round of its Low or No Emission Vehicle Deployment Program (LoNo). Funds will be awarded on a competitive basis to transit agencies and state transportation departments working either independently or jointly with bus manufacturers.
The LoNo program is focused on deploying new low- or no-emission production buses that are market-ready or near market-ready (not in development or prototype stages). It gives priority to the buses with the lowest energy consumption and emissions.
The previous round of LoNo funding, announced in February 2015, awarded $55 million in grants to ten US organizations.
All buses proposed for deployment must complete the Federal Transit Administration’s bus testing program, and follow FTA Buy America regulations. Priority will be given to tested zero-emission bus models with proven effectiveness (such as Proterra and BYD models already in service in several US cities).
“The LoNo program has helped deploy environmentally-sound, technologically-advanced vehicles across the country, providing a better riding experience for passengers and improving public health,” said Acting FTA Administrator Therese McMillan. “By reducing fuel and maintenance costs, these modern vehicles are a great public investment – saving taxpayer money in the long run while powering innovative American enterprises.”

The U.S. Department of Energy (DOE) has awarded more than $20 million in 10 projects to advance fuel cell and hydrogen technologies and enable early adoption of fuel cell applications, such as light-duty fuel cell electric vehicles (FCEVs).
"These projects announced today will continue to make advances in our rapidly expanding portfolio of hydrogen and fuel cell technologies," says Assistant Secretary for Energy Efficiency and Renewable Energy David Danielson. "Energy Department-supported projects have helped reduce the modeled cost of transportation fuel cells by 50 percent since 2006, and more than double durability and reduce the amount of platinum necessary by a factor of five."
The DOE says the hydrogen and fuel cell market continues to grow rapidly. According to the department’s newly released 2014 Fuel Cell Technologies Market Report, the industry grew by almost $1 billion in 2014, reaching $2.2 billion in sales - up from $1.3 billion in 2013. In addition, more than 50,000 fuel cells were shipped worldwide in 2014.
To further develop and advance these clean energy technologies, the DOE has selected seven projects to address the hydrogen and fuel cells research and development area, including hydrogen production via microbial biomass conversion, low platinum group metal catalyst development for fuel cell applications, development of integrated intelligent hydrogen dispensers, and hydrogen delivery pipeline manufacturing.
Three projects were selected to address early market and demonstration. These include the demonstration of mobile hydrogen refueling technology to address the lack of widespread hydrogen fueling stations, as well as fuel-cell-powered range extenders for light-duty hybrid electric vehicles.
In addition, the DOE notes the City of Ithaca, N.Y., has proposed to become home to one of the first commercial hydrogen-electrolyzer fueling stations in the northeastern U.S. and to ramp up outreach through the use of FCEVs.
