Since environmental destruction activities by human such as production of greenhouse gases and negative effects of Non-renewable fuel fossils is increasing nowadays, we want in the present study to deal with different types of renewable energies and have a general comparison about usefulness of each ones according to the climatic conditions of Iran; In addition, with the rapid decline of these resources, increasing energy demands and due to concerns about air pollution and global warming, research on renewable energy sources is becoming a priority. Iran is one of the rich sources of fossil fuels. However, it will undoubtedly face a reduction in these resources duo to expansion of use of them in the coming years. And certainly not making correct decisions about use a variety of renewable energies will definitely have devastating economic and environmental effects. Here, we also want to examine and compare advantages, disadvantages, and degree of economic and environmental efficiency of the three common types of renewable-energy power plants, including wind, hydroelectric, and solar power plants.
