Evaluation of Energy Efficiency in Transportation Sector with Analytic Hierarchy Process

Transportation is a sector of increasing importance between energy efficiency and production. Increasing the energy efficiency of this sector and effectively reducing energy consumption, which forms the economic building blocks of countries, is considered a critical step for the protection of the natural environment. The role of transportation in energy saving and alternative energy technologies in the creation of environmentally friendly cities is the main focus of this study. The aim of the study is to examine the effects of energy efficiency in the transportation sector, to identify the factors affecting energy efficiency and to offer solutions to them. Within the scope of the study, five main criteria were examined: CO2 emissions, energy consumption, gross domestic product (GDP), crude oil barrel price and fuel consumption. These criteria have a wide range of impacts, from human health to the world economy. The relationships and importance levels between the criteria were weighted using the Analytic Hierarchy Process (AHP). As a result of the analysis, it was determined that CO2 emissions and energy consumption were the most important criteria. It has been shown that energy consumption in the transportation sector increases CO2 emissions by negatively affecting the environmental impacts, and at the same time, the increase in the barrel price of crude oil reduces CO2 emissions. It has been observed that today's technology is looking for alternative energy sources because fuel consumption affects energy consumption and CO2 emissions. A good gross domestic product indicates the existence of a green environment with low emissions and low energy consumption. As a result, it has been determined that energy consumption and CO2 emissions, which affect each other in parallel, are more important parameters for the transportation sector.
