Abstract

Transport in general, especially road transport is a significant sector of energy consumption. This sector completely depends on oil supply, i. e. supply of oil derivatives and is at the same time the key source for green house gas emission. In the last year transport has faced the problem of rapid increase of oil prices on the world market. Mobility requirements are rising in the world and lead to an increase in the vehicle number and fuel consumption. At the same time, the fact that oil is a non-renewable energy source and that oil sources are concentrated in several regions in the world has lead to examination of possibili ties for secure supply in the future, decrease of import dependence and reducing environment pollution.
