    12-30% of Energy Put into a Conventional Car is Used to Move the Car Down the Road

    Not all of the fuel that is put into a car's fuel tank is used to move the car down the road. In fact, only 12-30% of the energy put into a conventional car is use d for that purpose. The rest of the energy is lost to engine inefficiencies or used to power accessories. The amount of energy loss varies depending on the type of driving – city, highway, or combined city and highway. The engine losses, such as exhaust heat and pumping, are higher for city driving than for highway driving. There are no idle losses in highway driving, but losses due to wind resistance and rolling resistance are higher for highway driving than city driving. All in all, there is great potential to improve vehicle fuel efficiencies with advanced technologies, such as hybridization, that address these losses.

    Louisiana DC Fast Charging Corridor Master Plan

    Updated 12/27/2018 - With the exception of Tesla owners, electric car owners in Louisiana currently do not have an adequate charging infrastructure along our interstate corridors. While the daily commute for a typical EV owner in their hometowns may be workable, taking their EV on road trips can often be a hassle. Louisiana Clean Fuels is currently looking for additional partners to help complete a master plan to create a well-designed charging infrastructure along our interstate corridors. The plan, explained below, will provide future site hosts with a business case to install EVSE at select sites across our state. We will also work with our stakeholders to secure funding to help offset the cost of installation. Support this project with a donation today!

    NEWCrowd sourcing website launched to collect input from EV owners and potential site hosts []


    On November 30, 2017, Louisiana submitted its proposal to the Federal Highway Administration (FHWA) for alternative fuel corridors. The state submitted proposals for three fuels along specific sections of our interstate system. On March 8, 2018, the state received notification of the approved signage-ready and signage-pending corridors. The fuels that received approval for corridors signage in Louisiana are CNG, Propane and LNG. The Louisiana Department of Environmental Quality (LDEQ) and Louisiana Clean Fuels (LCF) will now begin work with the Louisiana Department of Transportation and Development (LDOTD) to have the necessary signage produced so that the corridor is clearly marked.

    The Opportunity:

    The only fuel that did not qualify for signage was charging for electric vehicles. Under the FHWA guidelines, DC Fast Chargers must be spaced a maximum of 50 miles apart, each within 5 miles of the interstate in order for the corridor to be eligible for signage. To jump start the development of an electric charging corridor along our interstate system, LCF proposes creating a DC Fast Charging Master Plan for the state of Louisiana.

    The Plan:

    LCF has assembled a team of data experts, OEMs, EVSE experts, electric utilities and MPOs to begin work on a two-part plan. The first part of the Master Plan is to create the business case for potential DC Fast Charging sites that is backed up with comprehensive data which will aid in identifying the best locations for DC Fast Chargers along our interstates. LCF will collect highway data, economic data of the potential sites, and vehicle data from multiple sources along with existing infrastructure. The data will be used to conduct analyses and modeling that will reveal optimal DC Fast Charging sites in Louisiana.

    The second part of the Master Plan process is to conduct regional outreach meetings in the different planning commission / MPO territories across the state. Both LCF and LDEQ will host these round table meetings with area businesses, utilities, and elected officials in order to facilitate local acceptance and demand for EVSE charging infrastructure along their critical corridors.

    EVSE Site Ranking Criteria

    LCF will prioritize locations around the state for possible DC Fast Charging EVSE installations utilizing the Sawatch EVSE siting analytics and site ranking criteria such as, but not limited to:

    • Access to shopping and dining
    • Access to a recreational facility
    • Safety (well-lit, low-crime)
    • Electrical Capacity (408 volt, 3-phase power)
    • Within 5-miles of an Interstate
    • Preferred by utility service provider
    • Preferred by local government
    • Co-located with other Public EVSE
    • Co-located with Tesla Charging
    • Co-located with a hotel
    • Publicly accessible parking garages

    How can you help?

    Sponsors are being sought to fund the Louisiana Statewide DC Fast Charging Corridor Master Plan. All funds will go directly to paying for Phase 1 of the plan: acquisition of data sets and fees paid to LCF’s contractors for the modeling and analysis of potential sites along our interstate corridor. The completed plan will provide a business case for potential DC Fast Charging host sites. All sponsors will get access to the final plan for three months before the Master Plan is published. Additionally, entities from all sponsorship levels will be invited to participate in the Master Plan committee meetings, regional outreach meetings, and will receive recognition in all press releases and events related to promotion of and/or completion of the study.

    Thank you to our sponsors!

    EERE #1041: Households Take Fewer Vehicle Trips in 2017

    Transportation Analysis Fact of the Week #1041

    August 6, 2018

    Households Take Fewer Vehicle Trips in 2017

    The average number of vehicle trips made by a household in a year’s time was 1,865 in 2017, which translates to an average of 5 household trips per day (one-way).  That is 10% lower than the previous survey year, 2009, and 20% lower than the 1995 survey.  In 2017 there were fewer trips per household for work, shopping, other family/personal errands, and social & recreational purposes.  The rise in internet shopping, telecommuting, and social networking via the internet may be a factor in the decline, as total trips per household has been declining since 1995.

    Number of Vehicle Trips per Household by Trip Purpose, 1969-2017

    Note: A vehicle trip is defined as one start and end movement from location to location in a single privately-operated vehicle regardless of the number of persons in the vehicle.
