The U.S. transportation sector relies almost exclusively on oil; as a result, it causes about a third of the nation’s greenhouse gas emissions. Advanced technology vehicles powered by alternative fuels, such as electricity and ethanol, are one way to reduce oil consumption. The federal government set a goal for federal agencies to use plug-in hybrid electric vehicles–vehicles that run on both gasoline and batteries charged by connecting a plug into an electric power source–as they become available at a reasonable cost. This goal is on top of other requirements agencies must meet for conserving energy.

In response to a request, GAO examined the:

(1) potential benefits of plug-ins,

(2) factors affecting the availability of plug-ins, and

(3) challenges to incorporating plug-ins into the federal fleet. GAO reviewed literature on plug-ins, federal legislation, and agency policies and interviewed federal officials, experts, and industry stakeholders, including auto and battery manufacturers.

Increasing the use of plug-ins could result in environmental and other benefits, but realizing these benefits depends on several factors. Because plug-ins are powered at least in part by electricity, they could significantly reduce oil consumption and associated greenhouse gas emissions. For plug-ins to realize their full potential, electricity would need to be generated from lower-emission fuels such as nuclear and renewable energy rather than the fossil fuels–coal and natural gas–used most often to generate electricity today. However, new nuclear plants and renewable energy sources can be controversial and expensive. In addition, research suggests that for plug-ins to be cost-effective relative to gasoline vehicles the price of batteries must come down significantly and gasoline prices must be high relative to electricity.

Auto manufacturers plan to introduce a range of plug-in models over the next 6 years, but several factors could delay widespread availability and affect the extent to which consumers are willing to purchase plug-ins. For example, limited battery manufacturing, relatively low gasoline prices, and declining vehicle sales could delay availability and discourage consumers. Other factors may emerge over the longer term if the use of plug-ins increases, including managing the impact on the electrical grid (the network linking the generation, transmission, and distribution of electricity) and increasing consumer access to public charging infrastructure needed to charge the vehicles.

The federal government has supported plug-in-related research and initiated new programs to encourage manufacturing. Experts also identified options for providing additional federal support. To incorporate plug-ins into the federal fleet, agencies will face challenges related to cost, availability, planning, and federal requirements. Plug-ins are expected to have high upfront costs when they are first introduced. However, they could become comparable to gasoline vehicles over the life of ownership if certain factors change, such as a decrease in the cost of batteries and an increase in gasoline prices.

Agencies vary in the extent to which they use life-cycle costing when evaluating which vehicle to purchase. Agencies also may find that plug-ins are not available to them, especially when the vehicles are initially introduced because the number available to the government may be limited. In addition, agencies have not made plans to incorporate plug-ins due to uncertainties about vehicle cost, performance, and infrastructure needs.

Finally, agencies must meet a number of requirements covering energy use and vehicle acquisition–such as acquiring alternative fuel vehicles and reducing facility energy and petroleum consumption–but these sometimes conflict with one another. For example, plugging vehicles into federal facilities could reduce petroleum consumption but increase facility energy use. The federal government has not yet provided information to agencies on how to set priorities for these requirements or leverage different types of vehicles to do so. Without such information, agencies face challenges in making decisions about acquiring plug-ins that will meet the requirements, as well as maximize plug-ins’ potential benefits and minimize costs.

The recommendations are listed below:

• To enable agencies to more effectively meet congressional requirements, the Secretary of Energy should, in consultation with Environmental Protection Agency (EPA), General Services Administration (GSA), Office of Management and Budget (OMB), and organizations representing federal fleet customers such as Interagency Committee for Alternative Fuels and Low-Emission Vehicles (INTERFUEL), Federal Fleet Policy Council (FEDFLEET), and the Motor Vehicle Executive Council, propose legislative changes that would resolve the conflicts and set priorities for the multiple requirements and goals with respect to reducing petroleum consumption, reducing emissions, managing costs, and acquiring advanced technology vehicles.
• The Secretary of Energy should begin to develop guidance for when agencies consider acquiring plug-in vehicles, as well as guidance specifying the elements that agencies should include in their plans for acquiring the mix of vehicles that will best enable them to meet their requirements and goals. Such guidance might include assessing the need for installing charging infrastructure and identifying areas where improvements may be necessary, mapping current driving patterns, and determining the energy sources used to generate electricity in an area.
• The Secretary of Energy should continue ongoing efforts to develop guidance for agencies on how electricity used to charge plug-ins should be measured and accounted for in meeting energy-reduction goals related to federal facilities and alternative fuel consumption. In doing so, the Secretary should determine whether changes to existing legislation will be needed to ensure there is no conflict between using electricity to charge vehicles and requirements to reduce the energy intensity of federal facilities, and advise Congress accordingly.
• The Administrator of GSA should consider providing information to agencies regarding total cost of ownership or life-cycle cost for vehicles in the same class. For plug-in vehicles that are newly offered, the Administrator should provide guidance for how agencies should address uncertainties about the vehicles’ future performance in estimating the life-cycle costs of plug-ins, so agencies can make better-informed, consistent, and cost-effective decisions in acquiring vehicles.
• Once plug-in hybrids and all-electrics become available to the federal government but are still in the early phases of commercialization, the Administrator of GSA should explore the possibility of arranging pass-through leases of plug-in vehicles directly from vehicle manufacturers or dealers–as is being done with DOD’s acquisition of neighborhood electric vehicles–if doing so proves to be a cost-effective means of reducing some of the risk agencies face associated with acquiring new technology.

Last month (May 2009), the Toyota Prius was the top selling model in the world’s second-largest economy; the rival Honda Insight hybrid came in third, according to new car sales rankings—excluding minicars with displacements of less than 660 cc—released by the Japan Automobile Dealers Association (JADA).   

In April Honda was quite happy to report that its new Insight hybrid was both the best selling car in Japan for that month (outselling the Toyota Prius) and the first hybrid car to have that honor with 10,481 units. (Earlier post.) In May, the Insight dropped to third place with 8,183 units, behind the Prius and the Honda Fit, with 8,859 units.Toyota’s May performance was all the more surprising, since the third-generation Prius didn’t go on sale until May 18.  

The Prius posted 10,915 units in May, in Japan more than twice the 5,079 units sold in May 2008 and compared to 1,952 units in April 2009, according to the JADA data. (In the US, Toyota reported 10,091 units of the Prius sold in May.)

There are several possible explanations—beyond the fact that both Toyota and Honda have cut prices to make hybrids a little less niche and a little more mass market. First, generous government incentives: Japan’s stimulus package included a range of tax breaks for buyers of hybrid (and electric) vehicles which can knock thousands of dollars off the price tag. Japan has tougher mileage standards—but that affects what kind of cars manufacturers turn out, not what kind of cars consumers flock to. One huge difference is the price of gasoline—which automatically makes the hybrids more attractive, especially in a recession. Japan, like many European countries, slaps a hefty national tax on gas. Right now, Japanese pump prices work out to $4.61 a gallon. That compares to a U.S. national average of about $2.50 a gallon.

Spain’s fourth largest city is getting 75 public electric vehicle recharging stations throughout the city this year. Spain’s ambitious program of introducing EVs, hybrid and plug-in cars (a million units for 2012) is promoting the new network under the Movele program. Seville is getting recharging stations in the most used parking lots in the city, as well as at the airport, city hall offices and other official buildings. The plan includes 500 electric cars, which will be allocated not only to public institutions but for private users as well. It’s expected that each simple recharging post will cost €1,000.  The picture shows a recharging post in Lisbon, Portugal.

GM Defends the Volt’s Design
A recent Carnegie Mellon University study (pdf) challenged the real-world gasoline savings and cost effectiveness of plug-in hybrids like the Chevy Volt. GM’s Vice President Global Program Management, Jon Lauckner, who has been involved in the Volt project responded on the company’s blog. Find out what he had to say below.

All-Electric Range

The first thing is the electric range of the car. Somewhat strangely, the CMU study found that “for urban driving conditions and frequent charges every 10 miles or less, a low-capacity PHEV sized with an AER (range) of about 7 miles would be a robust choice for minimizing gasoline consumption, cost and greenhouse gas emissions.”

7 miles? Really?

Well, Jon Lauckner responds:

I’ll cut to the chase; for starters, the study’s endorsement of plug-in vehicles with only a “token” electric-only range (seven miles) overlooks the inconvenience of recharging for the vast majority of drivers (approx. 90 percent) with a daily commute that exceeds seven miles. I mean, honestly, how many customers are going to stop every seven miles and wait at least 30 minutes (if a car has a high-capacity charger like the Volt with the same level of electrical energy to match it) for their battery to be recharged? […] And, if customers don’t recharge during the day, these “token” plug-ins will run primarily on gasoline. How is that consistent with reducing green house gas emissions and our dependence on petroleum?
