Overall energy demand for commercial transportation grew at 2.4 percent annually from 1980 to 2005. However, the rate of change for each of the commercial sub-sectors has varied significantly.
The largest of these sectors, heavy duty vehicles (e.g. trucks, buses), had the most rapid rise in energy use at over 3 percent per year. The increase in demand for this segment alone was about 9 MBDOE from 1980 to 2005.
Aviation and marine demand growth has been in the 2 percent per year range.
In contrast, rail demand actually decreased over the period, driven by a significant drop in demand in the Russia/Caspian region.
Analyzing demand trends over time reveals a fairly stable relationship between commercial transportation energy consumption and GDP growth. This relationship is useful in assessing future demand requirements.
The next page describes the outlook for energy demand for commercial transportation to 2030.
