“…Zhang et al (2011a) make study on the energy and exergy efficiencies of China's each transportation sector during 1980-2009, from which they acquire the average overall energy and exergy efficiencies, with the values 21.22% and 19.95%, respectively. Zarifi et al (2013) investigate the energy and exergy efficiencies of Iran's transportation sector, and find that the energy and exergy efficiencies decreased from 22. 02% and 21.47% in 1998 to 21.49% and 21.49% in 2009, respectively. In fact, it is obvious that most studies on the efficiency of the transportation sector are analyzed in view of macro-perspective.…”

“…One can see that there was a fluctuation in both the energy and exergy efficiencies in the period between 1998 and 2009, and the minimum value of energy and exergy efficiencies occurred in the previous year. Some socioeconomic and political reasons, such as the increase and decrease in the export of petroleum and import of petroleum products, the establishment of new refineries, national subsidies, international sanctions, and war are considered as the main reasons for changes in the contribution of each fuel and, consequently, change in the overall energy and exergy efficiencies during the previous years (Zarifi et al 2013). It has to be borne in mind that efficiency improvements in transportation can be offset by increased mobility, see Fig.…”

Transportation of people and of goods plays an important role in modern life. It is a major source of anthropogenic CO 2. This chapter, after introducing some fundamentals of natural climate fluctuations as described by Milankovitch cycles, describes the causes and consequences of man-made climate change and the motivation for increased fuel efficiency in transportation systems. To this end, contemporary and future ground-based and air-based transportation technologies are discussed. It is shown that concepts that were already given up, such as turbine-driven cars, might be worthwhile for further studies. Alternative fuels such as hydrogen, ethanol and biofuels, and alternative power sources, e.g., compressed air engines and fuel cells, are presented from various perspectives. The chapter also addresses the contribution of CO 2 emissions of the supply chain and over the entire life cycle for different transportation technologies.

“…It is known that most of the energy used in world is derived from fossil fuel sources such as coal, oil and natural gas, which are called primary energy sources, and the increase in primary energy demand is accelerating due to the increase in income and population in the world. It is known that oil has the largest share in the world's primary energy consumption, especially as the main energy source of the transportation sector [5]. When the geographical distribution of oil reserves is assessed, it appears that the entire world is dependent on the Middle East for its oil reserves.…”

World population growth, together with urban development and industrialization, is increasing the world primary energy consumption every passing day. It is known that most of the energy used worldwide is derived from fossil fuels such as coal, oil and natural gas, which are called primary energy sources. In this context, as humanity continues to search for sustainable development and better living conditions, renewable energy production becomes a worldwide priority. Renewable energy has an extremely important place in respect to meeting the energy needs of countries with domestic resources, thus reducing foreign dependencies, by diversifying resources and ensuring sustainable energy use and minimizing the damage to the environment as a result of energy consumption. Within the context of alternative energy policies, agriculture-based biomass energy has found a wide application area all over the world, with environment-friendly, sustainable energy production and environmental management features aimed at development. However, the increasing production of biofuels due to the agricultural potential and technological levels of the countries has brought significant debates with it. In this case, scientists have voiced that algae biomass, defined as third generation, could be an alternative energy source and that they have many advantages. From algae biomass; studies on biofuels such as biodiesel, renewable aviation fuel / bio jet fuel, bio-gasoline / green gasoline, bio-butanol, bioethanol, methane has been widely developed. It is a very important development that the agricultural areas are not used during the cultivation of the algae, and that they can reproduce with great speed even in very small areas.
