|Series||Transportation research record -- 689|
Measured in gasoline gallon equivalents (GGEs), representing a quantity of fuel with the same amount of energy contained in a gallon of gasoline. The two factors affecting the average annual fuel use of a vehicle are the average miles traveled per year (correlative) and the fuel economy of the vehicle (inversely correlative). Operating conditions for vehicles, such as stop-and-start traffic conditions and weather, all affect efficiency and there can be wide variation for a given mode of transport across different.
Worldwide transportation energy consumption by mode in the IEO Reference case and Will consumers desire more fuel-efficient vehicles and will they prefer public The last two worldwide scenarios focus on different light- and/or heavy-duty vehicleFile Size: KB. When it comes to this subject, there is a lot of confusion around. Let’s try to clarify: * The energy efficiency is a physical property of the vehicle or the means of transport, and as such, it has nothing to do with costs nor economics, whether o.

Energy efficiency of various transportation modes (Transportation research record)Author: National Research Council (U.S.). This book highlights different initiatives taken to attain sustainable mobility systems with respect to energy efficiency, discusses issues relating to the future of sustainable transportation systems, and provides new thinking on the future of transportation in.

U.S. Department of Transportation, Federal Transit Administration, National Transportation Database, table 17 and similar tables in previous years, available.
Thus, there is not necessarily one mode of transportation that is the most energy efficient, as the amount of energy used for any type of transportation can vary greatly within that individual category.
However, when looking at this data from a practical standpoint and trying to determine how to make a more informed. The energy required for a travel mode is calculated by converting fuel types to gasoline equivalents.
Passenger capacity varies by mode. The average passenger load was used to calculate occupancy. UNESCO – EOLSS SAMPLE CHAPTERS EFFICIENT USE AND CONSERVATION OF ENERGY – Vol. II - Energy Efficiency in Freight Transportation - Clark W.
Gellings, Kelly E. Parmenter ©Encyclopedia of Life Support Systems(EOLSS) Figure 1. Modal share by weight of domestic freight transported, (United States).File Size: KB. Building on a previous post on the energy efficiency of various foods, I decided to create a list of transportation modes by fuel efficiency.
In order to compare vehicles with different passenger capacities and average utilization, I included both average efficiency and maximum efficiency, at average and maximum passenger loads. UNESCO – EOLSS SAMPLE CHAPTERS EFFICIENT USE AND CONSERVATION OF ENERGY – Vol.

Introduction There are several types of transportation mode used for passenger Size: KB. Description. Energy Efficiency: Concepts and Calculations is the first book of its kind to provide an applied, systems oriented description of energy intensity and efficiency in modern economies across the entire energy chain.
With an emphasis on analysis, specifically energy flow analysis, lifecycle energy accounting, economic analysis, Book Edition: 1. Energy efficiency progress (Figure 1) is measured from the ODEX indicator. This index aggregates the unit consumption trends for each transport mode in a single indicator for the whole sector.
It is calculated at the level of 8 modes or vehicle types: cars, trucks, light vehicles, motorcycles, buses, total air transport, rail, and water transport.
For cars, energy efficiency.

Energy Efficiency of different Transport Modes The infographic shows the energy efficiency from pedestrians, bicycles, Bi-articulated BRT buses (diesel), articulated buses (diesel), passenger cars and scooters.
The energy efficiency in transport is the useful travelled distance, of passengers, goods or any type of load; divided by the total energy put into the transport propulsion means. The energy input might be rendered in several different types depending on the type of propulsion, and normally such energy is presented in liquid fuels, electrical energy or food energy.
Transport modes such as mass transit and intercity rail have important roles in bringing about more energy-efficient passenger and freight transportation, particularly if they shift traffic to modes that can be more energy-efficient.
Petroleum is the main source of energy for transportation. Inpetroleum products accounted for about 92% of the total U.S. transportation sector energy use. Biofuels, such as ethanol and biodiesel, contributed about 5%. Natural gas accounted for about 3%, most of which was used in natural gas pipeline compressors.

Committee on Energy Conservation and Transportation Demand.; National Research Council (U.S.).
The efficiencies of present-day modes of transportation are reviewed. Future sustainable options are discussed. Transportation takes about 20% of the energy use worldwide , and this figure is likely to fact that transportation requires some form of mobile energy storage makes this topic especially challenging for the post-fossil-fuel by: 3.
Annual energy consumption in transport in the EEA grew by 38 % between and (32 % in EU). However, the economic recession caused a decline in transport demand, leading to a 3 % decrease in the related energy demand in the last decade.
The shipping sector saw the greatest decline of 10 % in energy consumption between and. One question we’ve fielded lately with the release of our US airline efficiency ranking is how the fuel efficiency, and therefore carbon intensity, of aircraft compare to other modes of transportation.
Vehicles meet a variety of transport needs, in terms of what is transported (people vs. goods), distance traveled (short intercity trips vs.
transoceanic transport), and. Energy Efficiency in Air Transportation explores the relationship between air transportation and energy use, starting with an analysis of air transport energy sources and their potential development.
The book examines how different elements of the air transport system make use of energy, with an analysis of various methods for optimizing energy consumption. Shift from less to more energy efficient transport modes The various transport modes can vary greatly in terms of primary energy efficiency, even with similar levels of loading.Energy Efficiency by Transportation Mode Source: adapted from J.D.
Chapman () Geography and Energy: Commercial Energy Systems and National Policies, New York: Longman Scientific & Technical. Within the transport sector there are significant differences between speed, energy costs, mode and type of loads (freight and passengers).Corridors have many different modes that in combination provide a range of transport services that ensure an efficient commercial environment.
Thus, in contrast to the situation in the European Union, rail freight transport occupies a more important market share in North America, but passenger rail has a negligible share.
