Energy usage is vital for social life and sustainability in the residential sector. This study examines the electrical energy utilization and efficiency of the Turkish residential and commercial sector in terms of sustainable energy and efficiency in 2013 by using energy and exergy analyses. The total energy input that was produced as 27.55% while the rest was obtained by imports in 2013. In this year, 35.02% 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 2013. It is clear from this figure that the energy efficiencies in the year studied range from 56.60 to 86.15%, while the exergy efficiencies vary from 5.05 to 24.76%. Additionally, researches on electrical household appliances efficiency indicated an efficiency of 86.15% for the first law of thermodynamic and 24.76% for the second law of thermodynamics.
