This post was written with Cynthia J. Burbank, National Planning and Environment Practice Leader at Parsons Brinckerhoff. It first appeared in the National Journal Transportation Experts Blog in response to the question: What should transportation departments do for electric cars?
The call for the government to act to promote plug-in electric vehicles (PEVs), and all clean alternative fuels for that matter, is to correct the clear market failures that exist in today’s petroleum-based transportation sector.
Historically, petroleum has been a key driver in the growth of the economy and development of nations worldwide. Gasoline and diesel fuel’s impressive energy density, portability, and low production cost made it the fuel of choice for nearly a century. All the while there have been costs, although they haven’t always been obvious. Petroleum’s impact on climate change and U.S. energy security, and the risks of drilling, result in real and significant costs to society, and currently the price of petroleum does not include those externalities.
Previous posts in this series discussed how the demand for electricity from plug-in electric vehicles (PEVs) would affect the grid as well as a potential problem related to clustering. This final post describes an opportunity for these vehicles to help increase the stability of the grid and hold down utility rates for consumers. As a reminder, a PEV is either an all-electric vehicle (EV) or a plug-in hybrid electric vehicle (PHEV).
In our previous post in this series, we provided evidence that the existing electrical grid has enough spare capacity to accommodate plenty of plug-in electric vehicles (PEVs), if the right incentives are put in place. In this post, we will discuss a technical problem that has its roots in social behavior.
The transition from traditional powered vehicles to electric vehicles will not be without its hiccups. While the aggregate impact of PEVs on the grid is likely moderate, one concern is clustering, which can be thought of as the realization of the famous comic strip Keeping up with the Joneses. If people buy what their neighbors have, this could lead to a clustering of PEVs in certain neighborhoods which might place excessive demand on local areas of the grid.
One of the main concerns over the electrification of vehicles is their impact on the electrical grid. Will they lead to power outages due to the increased demand in certain areas? Will a marked increase in electricity demand raise prices for consumers who don’t own a plug-in hybrid electric vehicle (PHEV) or an all-electric vehicle (EV)? In a series of blog posts, we’ll take a look at a claim from some utilities that vehicle electrification could actually help improve the stability of the grid while keeping costs low through a process called frequency regulation.
In this post, we’ll try to answer the capacity question. In order to determine whether the grid has the capacity to handle the influx of Plug-in Electric Vehicles (PEVs or PHEVs/EVs), utilities must estimate at what time of day these vehicles will demand power from the grid and how many of them the grid can charge at a time without causing power disruptions.
In tackling climate change, a diverse transportation sector can contribute greatly to reducing greenhouse gas (GHG) emissions. In 2008, the transportation sector accounted for 28% of U.S. GHG emissions, according to the EIA. In achieving the goal of reducing emissions, transportation policy must reduce GHG emissions from travel without compromising the mobility of Americans. To that end, electric vehicles provide a much-needed alternative to gasoline and diesel powered cars.
Carmakers are responding to this challenge by designing plug-in electric vehicles (PHEVs) and all electric vehicles (EVs). Nissan’s Leaf, a new electric vehicle, is slated to hit showrooms throughout the U.S in late 2010. One of two Leafs seen in public was on display last week at the Washington Auto Show where the Green Car Journal named the Leaf its 2010 Green Car Vision Award winner.
At first, Nissan will likely place prospective buyers on a waiting list, but it anticipates ramping up Leaf production at a factory it is retooling in Smyrna, Tennessee. The company secured a $1.4 billion loan from the U.S. Department of Energy (DOE) last week to prepare the plant to manufacture the vehicles and the advanced batteries that will power them. DOE points out that the facility will “create up to 1,300 American jobs and conserve up to 65.4 million gallons of gasoline per year.” The 150,000 vehicle-per-year factory positions the U.S. as a leader in the next generation of low-emissions vehicle manufacturing.
At the DC auto show, the Nissan representative shared details about the vehicle along with the company’s program to distribute it worldwide. Nissan is partnering with Better Place, an innovative electric vehicle services provider, to sell the Leaf in Denmark and Israel in 2011. The company intends to make modifications to the Leaf’s chassis to support Better Place’s battery switch stations. The Leaf will also meet SAE’s J1772 standard for electric vehicle charging. Lastly, by laminating the lithium-ion battery packs in order to make them self-cooling, Nissan solved a complex technical problem without using a computer control system. More information about the Leaf is available on Nissan’s website.
The L.A. Time reports Nissan hints at a sticker price of less than $30,000, before accounting for the $7,500 federal tax credit for plug-in hybrid vehicles and electric vehicles provided in the Recovery Act. No pricing information was available at the auto show.
The three most important issues to Americans today are the economy, jobs, and terrorism according to the Pew Research Center for the People & the Press. If one makes the logical connection between protecting against terrorism and promoting energy security, Nissan is timely in releasing the Leaf in 2010. With the Leaf, the company will create American jobs to manufacture an affordable vehicle that lowers U.S. dependence on foreign oil.
