BTU - British Thermal Unit
The average heat content of motor gasoline is 129,024 BTU per gallon. One quadrillion BTU is equivalent to 7.75 billion gallons of motor gasoline.
This indicator shows the level of energy use for transportation with respect to production of GDP and the levels of personal consumption in the United States over time. Transportation energy use reflects the seasonality of personal travel.
|Transportation Energy Use Per $ of GDP||Q4 01||Q1 02|
|Thousand BTU per Dollar of GDP||2,834||2,672|
|Percent change from same quarter previous year||-3.08||-5.73|
NOTE: The current value is compared to the value from the same period in the previous year to account for seasonality.
A trendline has been provided for transportation energy consumption. The trend has been calculated through a statistical procedure called Structural Modeling, in which the time series under study is decomposed into seasonal, trend and irregular components. For further information on this statistical procedure, see: S.J. Koopman, et al., Structural Time Series Analyser, Modeller And Predictor (STAMP), London: Timberlake Consultants Ltd., 2000.
