Comparing Energy Efficiency and Plug-in Electric Vehicle Provisions in Energy-Climate Legislation

Provisions in any legislation can be confusing. Trying to compare similar provisions across different bills can compound the confusion. To help make things more clear, we have two side-by-side comparison charts, one on energy-efficiency provisions, and the other on electric plug-in vehicle provisions, of this Congress’ energy and climate legislation.

Electric Vehicles and the Need for Public Policy

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.

Plug-In Electric Vehicles Could Help the Grid: Prospects with Frequency Regulation

This is the third post in a three-part series that explores potential impacts of electric vehicles on the electrical grid. Part 1 and Part 2.

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).

Plug-In Electric Vehicles Could Help the Grid: Following the Crowd

This is the second post in a three-part series that explores some potential impacts of electric vehicles on the electrical grid. Part 1 and Part 3.

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.

Plug-In Electric Vehicles Could Help the Grid: The Capacity Question

This is the first post in a three-part series that explores some potential impacts of electric vehicles on the electrical grid. Part 2 and Part 3.

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.
