Energy security is crucial for an energy policy but so far is not included in the current Strategic Environmental Assessment (SEA) program in Taiwan. The SEA report of energy policy prepared by the Bureau of Energy; Ministry of Economic Affairs; also demonstrated the same need. However; a feasible and quantifiable indicator has been missing. For the reason; this study is aimed to establish a practical assessment tool to assess energy security. Two indexes are suggested; which are the energy mix diversification (EMD) and energy import diversification (EID). The former one considers the national energy structures and expressed as Shannon index. The later is to assess the dependency on imported sources. The both indexes result in low energy security in Taiwan because of too high percentage of imported coal and oil in energy structure. The example of SEA policy is according to the Taiwan’s Sustainable Energy Policy Framework; in which the energy efficiency is set to increase 2% annually in the future eight years. The increasing energy efficiency does not contribute significantly to improve energy security. The indexes used in this study can assess diversity of the whole energy structure and the imported energy sources; should benefit to SEA quality and energy security assessment.
