Abstract: This paper presents energy analysis and exergy utilisation in the transportation sector of Cameroon by considering the sectoral energy and exergy flows for the last decade. The transportation sector, in Cameroon, is a two-mode system, including roads, which cover almost all domestic passenger and freight transport, and air. The latter is mainly used for international flights. In 2010, the average estimated overall energy and exergy efficiencies were 22.15% and 20.78%, respectively. This simply indicates that there is a large potential for improvement and efficiency enhancement. A comparison of the overall energy and exergy efficiencies of Cameroon transportation sector with the transportation sector of other countries for the year 2001 is also presented based on the data available. This reveals that the Cameroon transportation sector is least effective.

Keywords: energy analysis; exergy flow; exergy efficiency; transport industry; fossil fuel; exergy analysis; Cameroon; passenger transport; freight transport; air transport; international flights; road transport.
