The Transportation Energy Data Book (TEDB) is a compendium of data on transportation with an emphasis on energy. The TEDB is produced by Oak Ridge National Laboratory for the U.S. Department of Energy’s Office of Energy Vehicle Technologies Office. Edition is the latest edition. Transportation accounted for 69% of U.S. petroleum use in. The Global Commission for Urgent Action on Energy Efficiency will examine how progress on energy efficiency can be rapidly accelerated through new and stronger policy action by governments across the globe. It will develop a series of actionable recommendations that will be announced in the summer of The IEA is the global authority for.   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, technology evaluation, and policies/strategies Book Edition: 1. 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.

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. Section outlines energy use for U.S. transportation overall. Passenger and freight transport are covered in Sections and , respectively. Section briefly discusses the effects of alternative fuels on the efficiency of highway vehicles. Much of the discussion in this chapter is “vehicle-centric” in the sense that it focuses on. Passenger-Miles per Gallon. Passenger-miles per gallon (pmpg) is a metric for comparing mass transit and rideshare with typical passenger vehicle travel. Transportation system efficiency increases as the number of passengers increases or as the vehicle fuel economy increases for each transportation mode.

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). The U.S. Department of Energy's Office of Energy Efficiency and Renewable Energy announced a $1 million Water Resource Recovery Prize. Janu Prizes Powered by the Ocean. Febru Last fall I participated in the White House Summit on Ocean Science and Technology, where leaders discussed advancing ocean energy technologies. Transportation currently accounts for the largest proportion of U.S. greenhouse gas emissions of any sector (27%) and approximately 70% of U.S. oil use. Corporate Average Fuel Economy (CAFE) standards (and since , the accompanying greenhouse gas emissions standards), have had the largest impact of any U.S. energy efficiency policy.
