Turkey is not considered as a rich country in terms of energy sources and energy generating technologies. On the other hand, the demand for energy that needs to be provided using resources that have minimum cost, sustainable supply and long term cycle is increasing parallel to the economic growth in the country. Another important issue is the increasing cost of natural gas and coal along with the extra costs of emission and transportation. Increasing costs affect the electricity costs in such a country like Turkey in which energy generation is highly depend on the natural gas. Considering all public and private energy investments, Turkey might have more expensive energy in the future if necessary precautions are not taken and might have to import energy. In this research, the current energy sources are analyzed first, and then the relationship between economic growth and electricity demand is analyzed.
