During the human history, have taken place several energy transitions. It can be said that this development is natural. The role of the countries is crucial in the sense that they implement relevant policies to achieve this transition.Each transition comes with several advantages and drawbacks. One of the primary areas which accepts the negative effects is the environment- ecosystem. In the mid-1970s it was obvious that the burning of fossil fuels had caused serious damage in the environment and ozone layer. In the eve of the second millennia, the extensive use of oil, natural gas and coal for energy generation caused an overheat of the planet. Now, it was necessary for policies to be implemented to reduce the global temperature. The protagonists were going to be the countries and regional and international organizations. The key? The implementation of energy transition policies. One of the countries which targets to tackle with this climate change is Türkiye. This country has passed many energy transitions in its historical path. From 1923 till nowadays, the governments tried to design and implement energy transition policies for ameliorating the status and tackling with the climate change. Even though the efforts of the pre- Erdogan era were not very successful, under Recep Erdogan’s leadership, the progress is worth mentioning.
