Sustainable development is a changing process, circuiting investment, orientating technology and institution for compatible with the needs of the present and the future. In order to achieve sustainable development and make improvement in efficiency services, optimal and efficient ways for using energy must be evaluated and practiced. The weakness in efficiency of production process, transmission, distribution, consumption and not dependency on reliable energy needs sustainable development policy. In other words, sustainable development and environment production depend on the optimal use of energy resources especially for renewable energy. In this article, energy and its trend of changes are discussed at first. Then the importance of energy in creating sustainable development is discussed. The goal of this study is to introduce data and to evaluate other countries' experiences as well as using these experiences for macro policies in different fields and dimensions for improving efficiency.
