  • As the Postal Service prepares to acquire a new delivery fleet, electric vehicles may be a good option for deployment on many postal routes.
  • There is considerable variation among delivery routes, and many factors can make a route either more or less suitable to electric vehicle deployment.

In February 2021, USPS awarded a contract to produce and deploy 50,000 to 165,000 Next Generation Delivery Vehicles (NGDVs) over 10 years to replace its aging fleet. The agency announced its intention to make at least 10 percent of its NGDVs electric. The agency’s decision to electrify a portion of its delivery fleet will impact employees, operations, and services for decades to come.

In this white paper, the OIG sought to identify opportunities and challenges in adopting electric delivery vehicles. We assessed the suitability of using electric vehicles as delivery vehicles and analyzed the potential long-term cost savings of a new electric delivery vehicle compared to a new gas-powered vehicle. We also benchmarked the electric vehicle experiences of other federal agencies, foreign posts, and companies in the logistics and shipping sector.

We identified several clear benefits of adopting electric vehicles into the postal delivery fleet, including improved sustainability and environmental impacts. Our research confirms that electric vehicle technology is generally capable of meeting the Postal Service’s needs.

The adoption of electric delivery vehicles could save the Postal Service money in the long term — at least for certain delivery routes. The upfront costs of an electric delivery vehicle and necessary charging infrastructure is significantly higher than the cost of buying a new gasoline-powered vehicle, but once purchased, electric vehicles are generally cheaper to operate. For example, longer routes are more suited to electric vehicles because the agency saves money on each mile driven.

On March 14, 2022, we received a congressional request to review the Postal Service’s compliance with the National Environmental Policy Act (NEPA), among other issues, that are not addressed in this paper. The OIG will be doing additional work in response to that request.

    I believe it's the perfect time in our country to obtain and deliver us mail throughout the country utilizing the awesome power of electricity as this is the begining of the new green deal. Electricity is a core system of power that will continue to unlock more innovations and provide what will be needed throughout the future. EV is happening and will not be overlooked or put aside

    Daily, I look outside around the mail delivery time since it is exciting to see what new things come to my mailbox. However, I find myself repeatedly seeing if the USPS truck is electric. As a young person, it is extremely important for your institution to convert to a 100% electric vehicle fleet within the decade (before 2030) now that the Inflation Reduction Act has been signed into law. Please, end the use of gasoline at USPS. It’s the right and most cost-effective thing to do.

    Hello, As a Registered Independent voter with a degree in Geology and Earth Science, I implore you to move to sign the US Postal Service vehicles to commit to 95% Electric Vehicles within your fleet. You are in a unique and amazing position to really do something to have a positive impact to improve the very real and very frightening extreme weather trajectory. It is with a heart full of gratitude that I ask you to do the right thing. Cordially, A.B.

    Electricity to charge vehicles requires mostly coal now. Batteries require dirty mining and pose an e-waste problem. Trip range is limited per charge and unpredictable. Go with the tried and true internal combustion, which are highly efficient now.

    I add my voice to the many others calling for the USPS to convert its fleet as much as possible to EVs or other nonpolluting, renewable options. Not only will this help us to get out of the climate mess we're in, but it's the right thing to do patriotically--wind, solar, and other renewables are "home grown" American resources that will never run out and aren't subject to the interruptions of broken supply changes and the manipulations of unfriendly foreign powers that use oil as a political weapon. EV powered vehicles makes America more free as well as more clean and responsible.

    I am highly concerned with the U.S. Postal Service's plan to spend up to $11.3 billion on antiquated, gas-guzzling delivery trucks. I encourage you to use the Supplemental Environmental Impact Statement (SEIS) process to redress the faulty analysis and failures of your initial plan and to instead pursue a new fleet of 100% electric vehicles (EVs). We’re running out of time to stop the climate crisis, and President Biden has directed the federal government to transition to 100% zero-emissions vehicles by 2035. As the government agency that operates THE largest fleet of vehicles, you have a responsibility to do your part to fight climate change by purchasing a fleet of new, electric delivery trucks that will save money, cut climate pollution, and move us toward a clean energy future. Thank you.

    Once the newness wears off of the EV it'll be nothing but complaints. I think the P.O. just fell into the big "climate change" pool. Gas isn't going away and yes the climate will change. We don't need to worry because we'll all be dust looong before.

    President Biden needs to have staff find a way to lend the USPS the difference in cost between an electric-vehicle and a gas-powered vehicle. The USPS can pay back the money over a period of time as the cost savings from the electric vehicles are realized. Also, possibly money from the VW environmental settlement could be provided to the USPS. having USPS vehicles running around with "Electric Vehicle" painted on the sides will help promote the EV industry.

    My name is Ayla Bella, I am a resident of Columbus, Ohio. I wanted to write to express my desire for an electric fleet. According to the Pew Research Center, 2/3 of Americans believe the government isn't taking strong enough action on climate change (2020). With the recent Supreme Court decision limiting the power of the EPA to reduce emissions, we need action more than ever. An electric fleet would still create emissions through electricity consumption of course, but it is far more emission-efficient and it presents an opportunity to be zero-carbon in a future of renewable energy. We need every agency and organization to do everything in their power to reduce emissions. I implore you to be a part of the solution.

    For one thing, every vehicle that is purchased should be right side driving not like in the past with a purchased vehicles with only left side driving and that limits what that vehicle can be used for example riding routes. Our fleet is barely lasting. And as to the electric vehicles what produces that electricity, fossil fuels!

    These people have no idea how the postal service works. Running the truck for 7 or 8 hours a day 7 days a week the battery might last the entire day for a short while but very soon just like cell phone batteries they will run out of power faster and faster.

    There could be an effort for solar rooftops to charge these vehicles, also! The cost equivalent would be $1.00 per gallon. Get real. We can do much to counter the environmental damage of gas and oil far quicker - at war-time speed.

    It's time we changed the way things have been done in the past with respect to a future which portends to be different and where fossil fueled vehicles are detrimental to the atmosphere and our health. This is especially important when there are reasonable environmental alternatives like electric vehicles that can do the same as fossil fueled vehicles and don't have the deleterious side effects contributing to global warming and climate change. Let's change now before it's too late to change rather than being stuck in the past thinking.

    I need to read of the improvements that have occurred since my topical paper in college saying that was what I would have done 30+ years ago! Nothing can/will happen before 'we the people' decide, with a TON of research on the topic. I believe that the public is ready for my then futuristic prediction of the electric fleet we now agree upon.

    This is getting petty confusing. My heart says go with electric. But there does not seem to be any convincing pro and con details. Reading through some comments I find a cot of $18,000 per vehicle as well as electric is not suitable for many routes. So I wonder if the eighteen grand per charging station takes into consideration adaptability for V2G (vehicle to grid) and extensive solar/thermal roof installations and new technology in the pipeline. Keeping a toe in the water at this point seems sensible. No politics please.

    solar panels, windmills, larger scale storage batteries....Partner with other government agencies and private entities to use USPS as a test bed for current and future technologies... What a great testbed USPS is with facilities across the country... Can I hazzard a guess that there are many USPS facilities which could be self sufficient using clean technology?

    This is a bad financial, social, and environmental decision on the part of the USPS. EVs should comprise the bulk of the new fleet. I urge you to reconsider your bid and purchase a majority of EVs. USPS routes are so limited in range that most USPS vehicles are unlikely to need nightly charging, and regenerative braking is well-suited for the stop-start dynamic of delivering mail. Lower maintenance costs and gas costs will make up the slightly higher purchase price. On top of that, USPS will be actively worsening the climate crisis with a majority gas fleets, affecting itself, its routes, and the people that the USPS serves. Please reconsider.

    We have a post office box at our local Post Office and also get home delivery. I am a strong supporter of the U.S.P.S and I'm astonished that anyone who cares about the future of the U.S.P.S. would recommend continuing to rely on gasoline engines when it is so clear that the future is going to be electric for all vehicles. If they want to hang onto a few, go for 10% gasoline but please don't waste our money on more than that. Yes, it requires a large investment to start. But, consider the money that will be saved every year. Gasoline engines are wasting our money now.

    The Postal Service needs to join the effort to slow or reduce the long term effects of Global Warming. With the huge fleet and significant mileage drive by the post men and women, this is a golden opportunity to be a leading force for the future. Electric vehicles upfront cost is offset by the drastically reduced maintenance of an ICE vehicle, as well as the significantly less expensive "fuel" charges. Also, this volume of purchases of EVs and their batteries will help reduce the overall cost of EVs due to purchasing manufacturing in large volumes.

    Over 90% of routes can be done cheaply on EV vehicles . Please don’t get gas versions or do just 10% gas. That makes sense

    I fully support the USPS transition to EVs. We need to address urban air pollution in many regions of the USA plus reduce greenhouse gas emissions. Burning one gallon of gasoline produces approximately 19 pounds of CO2. Today, we are at 415 ppm of CO2 in the atmosphere and this trend continues upward as demonstrated by the Keeling Curve. Climate change correlates to droughts, wildfires, and other extreme weather events plus melting ice caps and glaciers leading to sea level rises and land intrusion. It's time to make the transition now to EVs for the future of our children, grandchildren and planet. Paul E Jacobs, 40 year air pollution expert and consultant.

    How many years have we been coming out of an ice age? Do you think poor forestry management (not controlling underbrush) may be a major contributor to wildfires? Have you ever wondered how many hours a day a mail truck is on the road?

    The economics of the decision clearly favors electric vehicles. The life of electric vehicles is much longer and minimal service is needed. The technology is here now. Battery life is improving daily. Try flipping the plan: 10 percent petroleum powered for the first of 10 years, and all electric after year one.

    If the EV is charged with electricity generated from coal, oil or gas does the EV burn less fossil fuel per vehicle than a gas powered vehicle ?

    Mar 25, 2022
  • anon

    Yes, it does. Electric motors are more efficient than internal combustion engines. Even when an EV is charged from a fossil-heavy grid, it produces significantly less emissions per mile than a gasoline engine.

    Hi Richard, In many regions of the USA, electricity is generated by hydroelectric dams and renewable sources such as wind, tidal, solar and geothermal. In California, all electricity will be from these sources by 2045 and many states are following this same policy. So yes, EVs produce zero emissions when operated in these regions. In regions where electricity is generated by burning oil, gas and coal, there are emissions associated with recharging EVs but those power plants comply with strict EPA standards. Over time, they will be replaced with renewable energy power plants which means zero emissions.

    The USPS clearly gave the OIG incorrect information. The upfront cost of an EV, as formally bid during the contractual bidding process, was lower than the price being paid for the Oshkosh ICEs. Since the upfront cost was lower, even when adding in $7,300 as suggested by OIG, then the upfront cost was actually lower. This is possible because bidders could bid to the specification and did not need to include all kinds of consumer comfort features. Since the OIG recognizes that the fuel and maintenance are lower, then the OIG needs to formally request information about the bids and correct this report as necessary. If an additional $6.9 billion is added then the USPS will effectively be paying $108,000 per vehicle,

    In response to Charles' points: - Charging stations can be the size of an outlet (level 1/level2) or a smart charger can be about the size of my hand. There should possible to install where the vehicles live today. - The power failures comment is the largest concern. Assuming they equip the vehicles with a city range of 100mi and most vehicles only travel 20mi, with bad weather, etc the max usage would be between 20-40%. If the batteries stay charged each night, and there was a 100% outage one night, the vehicles should still be able to perform. - Power demand is a bell curve, high during the day (8-6pm) and low at night (6pm-8am). The grid can easily handle charging in those off hours.

    California is already telling people not to charge their cars due to brown-outs in many areas already this year. The infrastructure is not in place to support this nonsense, build the infrastructure FIRST then deploy the magic cars with the toxic batteries that we have no disposal/recycle program for. Replacing the batteries on these vehicles is more cost prohibitive than just buying a new car in most cases. $22k for a new car or $15k to replace the battery.... Green my butt.

    This report is based on a Postal Service model of estimated costs of vehicles and that data is redacted. In fact the USPS received two firm offers for electric vehicles. By supplying assumed data, rather than the actual offers, the USPS appears to have misled the OIG. By redacting the assumed data, for which there is no valid commercial or legal reason, the OIG appears to be misleading the public. The USPS has gone to considerable lengths to disguise the facts of the contract despite the statements by other agencies, such as the EPA, that the analysis, on which the award would have been based, was completely flawed.
