Abstract
This study evaluates the energy utilization efficiency of the Turkish residential-commercial sector (TRCS) and electrical house applications in 2011 by using energy and exergy analyses. Of the total energy input, 28.15 % was produced in 2011, while the rest was obtained by imports. In 2011, 34.47 % of Turkey’s total end-use energy was consumed by the residential-commercial sector. Annual fuel consumptions in space heating, water heating, and cooking activities as well as electrical energy used by appliances are determined for the period 2000–2011. It is clear from this figure that the energy efficiencies in the years studied range from 57.05 to 65.53 %, while the exergy efficiencies vary from 8.02 to 10.07 %. In addition, researches on EHA efficiency indicated an efficiency of 81 % for the first law of thermodynamics and 22 % for the second law of thermodynamics.
