Energy efficiency is one of the most critical dimensions in energy consumption and the technologies improving energy efficiency thus decreasing energy demand as well as greenhouse gases have been becoming widespread in recent years. On the other hand, the fact that the savings owing to the improvements in energy efficiency would not happen as expected indicates a phenomenon which has been being addressed for a long a time in the literature and practice: Rebound Effect. This concept emphasizes that the cost advantage due to an improvement in energy efficiency would offset some of or overall expected gains resulting from this efficiency improvement. This study focuses on the direct rebound effect in personal automotive transport for households in Turkey. A survey with 472 participants was conducted within the study. The rebound effect analyses are performed by the quasi-experimental method and based on the participants from 4th and 5th quintile income groups for whom the data for both the current and the previous cars are available. Besides, the distinct fuel types (gasoline, diesel and LPG) are taken into account in a single framework and the rebound effects are calculated separately according to the unit energy cost criteria and energy intensity criteria. The estimations are 10.08% and 25.40% for in-city and intercity, respectively, based on the former criteria while it is 16.77% and 31.51% based on the latter criteria. On the other hand, the effect of the fuel price is analyzed by estimation of price elasticity of fuel consumption which is the first attempt for micro level in Turkey. The estimation results of the price elasticity of fuel demand showed that the price elasticity of in-city consumption is -0.25 for gasoline, -0.22 for diesel and -0.28 for LPG; price elasticity of inter-city consumption is -0.29 for gasoline; 0.22 for diesel and -0.19 for LPG.

Energy efficiency and rebound effect for household gas consumption: evidence from Ankara Yılmaz, Zehra İlknur; Sarı, Ramazan; Department of Earth System Science (2019) Increasing energy demand and concerns about energy security and climate change have led to energy efficiency to become one of the important energy policy objectives in many countries. It is conceived that energy efficiency improvements will decrease energy consumption and CO2 emissions. However, actual efficiency savings are often less than projected savings because of consumer behavior. This concept is known as the rebound effect which is an important factor to be considered while estimating results of ene...
Transformation pathways toward a sustainable energy system in Turkey Fathurrahman, Fahman.; Soytaş, Uğur; Department of Earth System Science (2019) The important factors for designing and implementing a sustainable energy system consist of a sufficient, affordable, secure, and environmentally sound energy supply along with the efficient use of energy. Given its high dependency on foreign energy resources, the current energy system in Turkey is far from satisfying the criteria of a sustainable energy system. In addition, relying solely on fossil fuels is no longer a proper alternative mainly due to its impact on climate change and vastly diminishing res...
CHARACTERIZATION OF LATENT THERMAL ENERGY IN A STORAGE UNIT WITH FIBONACCI-SEQUENCE-INSPIRED FINS Baghaei Oskouei, Seyedmohsen; Bayer, Özgür; Department of Mechanical Engineering (2023-1-19) Latent thermal energy storage (LTES) is a viable method to mitigate one of the main problems with renewable energy sources, such as solar energy, which is their intermittent nature. LTES units take advantage of the large latent heat of fusion in phase change materials (PCMs) to store a substantial amount of energy in a relatively small volume, making them efficient and economical. The major challenge with PCMs is their low thermal conductivity, eventuating long melting (charging) and solidification (dischar...
CAD – integrated size and shape optimization of steel lattice energy transmission line towers using simulated annealing Şahin, Serkan; Hasançebi, Oğuzhan; Department of Civil Engineering (2016) Energy transmission grids have been undergoing drastic changes due to increasing energy demand throughout the world in the recent years. As a result of this trend, sufficient electricity should be transferred from production centers to consumption areas. Therefore, overhead transmission lines (OHTL) gain high importance to be designed on the land reliably and economically. A significant amount of overhead transmission lines is constituted by steel lattice towers. Transmission line towers serve to keep the c...
Feasibility of pumped-storage hydraulic systems based on hourly variation of electricity prices Barbaros, Efe; Aydın, İsmail; Department of Civil Engineering (2019) Global energy demand increases every day due to growing needs. The ideal of eco-friendly, sustainable and low cost energy generation relying on countries’ own domestic sources increases the interest in renewable energy in the 21st century. However, the intermittent nature of the renewable energy brings the importance of and the need for energy storage to surface. Pumped storage hydroelectricity (PSH) has been in use worldwide for a long time with this purpose thanks to its large scale storage capacity and p...
