It is a fact that has been proven by scientific findings that in parallel with the rapid increase in today’s energy consumption, the conventional energy sources will be exhausted in the near future. Until today, mostly fossil fuels have been used in energy production. As a result of the use of these resources, negativities such as global warming, climate change and environmental pollution have occurred. Renewable energy sources should be used to eliminate these negativities. In this study, the potentials of renewable energy types such as solar, wind, geothermal, hydroelectric, hydrogen, biomass and wave energies in the world and in our country will be emphasized and their positive and negative effects on the environment will be investigated. Renewable energy sources in our country will be discovered and awareness will be created on this issue.
