Introduction  Energy alternatives is an effective measure to promote new energy consumption, improve energy efficiency, and increase the proportion of electricity in terminal energy consumption, it is crucial that rationally select technology of energy alternatives and implement it.

  Method  This paper proposed an evaluation system based on regional applicability, economy and popularization difficulty, and the improved analytic hierarchy process(IAHP)was applied to determine the weight coefficient of each index.

  Results  Finally, the model is verified by researching object in a southern region. The results show that the model analysis results are consistent with the actual situation, indicating the correctness and rationality of the model. Secondly, the model excludes human intervention factors and provides a scientific methodology, which can actually guide the regional electric energy replacement development.

  Conclusion  At the same time, this paper put forward measures to promote the development of energy alternatives, combining the precedence order conclusion and its technology.
