In order to meet the growing energy needs in rapidly developing technology in today's world, energy production from renewable and sustainable energy resources, other than traditional energy resources is the basis of the distributed energy systems. Distributed energy production is an energy production technology that uses clean, environmentally friendly, many different fuels and it improves systems reliability. It is well known that the electrical energy production and consumption are factors to determine countries' civilization levels. Disruptions in the electrical energy production affect basic industry, commercial developments and daily life, negatively. 80% of the world's commercial electrical energy production depends on finite and non-renewable resources such as coal, oil, natural gas and uranium. In this study, for the purpose of gaining awareness about the harms of these resources to environment and human life, it is emphasized the importance of distributed energy resources and also examined and given knowledge about distributed energy generation technologies and their place in Turkey.
