The main objective of this paper is to express the positive features of renewable energy and the necessity to substitute fossil fuels, especially oil, with these novel sources of energy. nonetheless, the crucial question which should be answered primarily is “what are the key advantageous of renewable energy, especially in countries like iran with considerable and inexpensive underground resources like oil and natural gas?”. renewability, flexibility, cleanliness and creation of new job opportunities are some of the most significant benefits of renewable energy. in addition, this type of energy not only does not suffer from fossil fuels drawbacks but also provides some benefits for countries. while dependency on oil challenges the security of countries in various areas - political, economic, social and environmental – the new alternative energy provides sustainable development and security for their consumers. this matter will be discussed throughout three parts in this paper by aid of descriptive-analytical method. the result, with emphasis on iran, will demonstrate there is no alternative to these new, clean and renewable energy sources.
