The Position of Renewable Energies in Passenger Susta inable Transportation Theory

Along with the development of human societiesʹ needs and, as a result, the development of the respective services performed by industrial, official and welfare centers, transportation serves as a link between support and demand of these services. On the other hand, transportation is etrecting and affected by such a development. Nowadays, the multifaceted approach to the issue of development in order to attain urban sustainable structure, has led to the theory of sustainable transportation to be viewed as a strategy by urban experts and managers. One of the most important issues in sustainable transportation th eory is energy. The high ratio of transportation energy consumption per capita and its direct effects on environment as weU as its consequences on society development indicates the position of renewable energies in sustainable development theory. Because of the debilitation of energies acquired through fossil resources, many national, regional and international associations are now looking for the support programs for developing the technologies of various kinds of renewable energies. In this paper, after providing a comprehensive definition of renewable energies and sustainable development, a number of measures to evaluate the position of renewable energies in passenger sustainable transportation theory arc introduced. These measures and t.he definitions presented here may clarify this new theory in urban management.
