Are Electric School Buses Safe?

Are Electric School Buses Safe?

While extremely rare, school bus fires are possible with any type of school bus. In general, electric vehicle fires are much less common than fossil fuel vehicles. A 2016 USDOT study found that school bus fires in the U.S. occur, on average, slightly more than daily, mostly starting in the engine area, running gear, or wheel area.

Why Clean Cities?

The United States consumes approximately 20 million barrels of petroleum per day, about three-fourths of which is used for transportation.

Support U.S. Economy and Energy Security

Transportation accounts for nearly one-sixth of the average American household’s expenses PDF (second only to housing). Improving efficiency and reducing costs in this sector can make a notable impact on our economy.

Reduce emissions impacting air quality and public health

Widespread use of alternative fuels and advanced vehicles could reduce the greenhouse gas emissions, smog-forming compounds, particulate matter, and other air pollutants that impact our air quality and public health.

We work with fleets of all vehicle sizes, vehicle numbers, and vocations to find ways to reduce petroleum consumption through the use of alternative and renewable fuels, advanced vehicles, and other fuel-saving measures.

Alternative and Renewable Fuels

Many different fuel options exist which can help displace petroleum consumption and reduce emissions. These fuels are defined in the Energy Policy Act of 1992 (EPAct) including biodiesel, electricity, ethanol, hydrogen, natural gas, propane. Alternative fuels may include both renewable and non-renewable fuels, and interest in their use is expanding among the general public as well as large fleets. Although availability of different fuels has sometimes been a challenge in the past, refueling infrastructure is expanding throughout the country and specifically Connecticut to meet the growing demand.

icon_biodiesel_greenBiodiesel is a domestically produced, renewable fuel that can be manufactured from vegetable oils, animal fats, or recycled restaurant grease for use in diesel vehicles. Biodiesel’s physical properties are similar to those of petroleum diesel, but it is a cleaner-burning alternative. Using biodiesel in place of petroleum diesel, especially in older vehicles, can reduce emissions. To find out more about biodiesel, visit the US Department of Energy’s biodiesel website or you can download a PDF fact sheet to print out.
icon_electricity_greenElectricity can be used to power all-electric vehicles (EVs) and plug-in hybrid electric vehicles (PHEVs). These vehicles can draw electricity directly from the grid and other off-board electrical power sources and store it in batteries. Hybrid electric vehicles (HEVs) use electricity to boost fuel efficiency. Using electricity to power vehicles can have significant energy security and emissions benefits. To find out more about powering cars with electricity, visit the US Department of Energy’s electricity website or you can download a PDF fact sheet to print out.

You can download a list of available EVs, PHEVs, and fuel cell vehicles (FCVs) with data including make, model, year, range, MPGe, MSRP, federal tax credit, and the Connecticut Hydrogen and Electric Automobile Purchase Rebate (CHEAPR) incentive amounts.

icon_ethanol_greenEthanol is a renewable fuel made from corn and other plant materials. The use of ethanol is widespread—almost all gasoline in the U.S. contains some ethanol. Ethanol is available as E85—a high-level ethanol blend containing 51%-83% ethanol depending on season and geography—for use in flexible fuel vehicles. E15 is defined by the Environmental Protection Agency as a blend of 10%-15% ethanol with gasoline. It is an approved ethanol blend for model year vehicles 2001 and newer. To find out more about ethanol, visit the US Department of Energy’s ethanol website or you can download a PDF fact sheet to print out.
Hydrogen, when used in a fuel cell, is an emissions-free alternative fuel that can be produced from diverse domestic energy sources. Research and commercial efforts are under way to build the hydrogen fueling infrastructure and produce hydrogen fuel cell vehicles that are practical for widespread use. To find out more about hydrogen, visit the US Department of Energy’s hydrogen website.

icon_natgas_greenNatural gas is a domestically produced gaseous fuel, readily available through the utility infrastructure. This clean-burning alternative fuel can be used in vehicles as either compressed natural gas (CNG), liquefied natural gas (LNG), renewable natural gas (RNG), or biogas. To find out more about natural gas, visit the US Department of Energy’s natural gas website or you can download a PDF fact sheet to print out.

icon_lpg_greenPropane, also known as liquefied petroleum gas (LPG) or propane autogas, has been used worldwide as a vehicle fuel for decades. It is stored as a liquid, and propane fueling infrastructure is widespread. To find out more about propane autogas, visit the US Department of Energy’s propane website or you can download a PDF fact sheet to print out.

Alternative Fuel Vehicles

As vehicle technology continues to advance, the variety of vehicle types available is increasing rapidly. Consumers and fleets can now choose to purchase vehicles that use an alternative fuel, an advanced hybrid powertrain, all-electric vehicles, energy-efficient diesel, or simply a highly efficient conventional gasoline engine. More choices, such as fuel-cell vehicles are on the horizon. The Department of Energy provides a list of energy-efficient technologies that are offered on many vehicles available today. AFVs are available either as conversions or as original manufacturer equipment, and come in both light-duty passenger vehicles and heavy-duty vehicles and equipment. Alternative fuel vehicles (AFVs), as defined by the EPAct, include any dedicated, flexible-fuel, bi-fuel, or dual-fuel vehicle designed to operate on at least one alternative fuel. To the right are the definitions of each type.


Designed to run only on the alternative fuel.


Capable of operating on gasoline, E85, or a mixture of the two.


Designed with two separate fueling systems that allows for operation on natural gas or propane and conventional gasoline.


Requires both alternative fuel and diesel fuel storage and delivery systems. Mainly developed for heavy-duty applications-usually out of warranty.

GNHCCC and its stakeholders have received several grants throughout the past few years! Click on the tabs below to find out what projects are being funded thanks to these awards.

The Greater New Haven Clean Cites Coalition, Inc. (GNHCCC) partnered with Plug in America to promote and demonstrate plug-in electric vehicle (PEV) use by establishing local Connecticut showcases that provide a hands-on consumer experience and in-depth education in a variety of venues. The project will help promote the use of PEVs to reduce greenhouse gas emissions and dependence on petroleum in transportation. The project also covers the Northeastern states Rhode Island, Massachusetts, Connecticut, and Vermont. Visit to see our first event of the project.

Public fleets are seeing huge benefits from the deployment of electric vehicles (EVs). By eliminating fuel consumption, EVs reduce costs to fleets, promote energy independence and help protect the environment. Although EVs are increasingly becoming a successful application for fleets, higher incremental costs, procurement processes, and insufficient charging infrastructure remain as critical barriers to adoption.

EV Smart Fleets seeks to address these barriers by aggregating state and local fleet purchases for EVs and charging stations through a multi-state aggregated EV solicitation and procurement agreement. EV Smart Fleets will leverage the purchasing volume of public fleets across the country in order to reduce vehicle and infrastructure costs, improve contract terms, provide access to a wider range of EV models, and expand access to charging infrastructure. This multi-state procurement will be issued and managed by the National Association of State Procurement Officials (NASPO) through its ValuePoint Program.

CTCCFFThe Greater New Haven Clean Cities Coalition, Inc. (GNHCCC), together with over 30 partner organizations will develop and implement a state-wide, fuel-neutral effort that will deploy 269 alternative fuel vehicles (AFV) through incremental funding and provide fueling capability for 21 additional fleet vehicles and infrastructure necessary to directly support the vehicle deployments as part of the Connecticut Clean Cities Future Fuels Project. The project will increase the utilization of alternative fuels; strengthen the availability of alternative fuels for fleets and commercial consumers along major corridors in the state; raise awareness and foster greater understanding of alternative fuels and advanced vehicle technologies through a targeted outreach and education effort; create and retain jobs; reduce dependence on foreign oil; reduce harmful emissions; and contribute to a sustainable alternative fuels market.
BioWatz_Logo_FinalFunded in FY2008, the BioWatz Project allowed the GNHCCC to work with Chris Glynos at BioPur, Inc., located in Bethlehem, CT, to build on the biodiesel production facility operated by Glynos. The project engaged an integrated team to design, develop and deploy a Power Generation System at the BioPur facility which would enable the production of electricity with biodiesel. The project proved to be very successful, allowing Glynos to sell his renewable power to the local power company — after he uses some of it to provide power for the biodiesel production facility. The project collected data through a system designed and installed by Sabre Engineering of Colorado and Innovation Drive, the project management firm provided support to the growth of this operation. The federal project officially ended in late 2010.
TrolleyLineThe City of New Haven in conjunction with the GNHCCC deployed an electric trolley system in downtown New Haven during the early 2000’s. E-Bus of Downey, California built four 22 foot dedicated electric trolley replicas that had the capability of both standard battery charging and fast charging. The batteries were charged with “Green Electric Power” derived from waterpower, wind and solar. The project provided a clean alternative fuel for public transportation. Everywhere the electric trolleys were put into service, mass transportation ridership increased dramatically because people appreciated the electric power train’s smooth, quiet, non-polluting ride. By going with the electric trolley technology, a reduction in dangerous soot particles associated with standard diesel powered buses was realized, as well as reducing the number of fuel trucks carrying foreign fuel to the vehicle refueling locations.
