This paper presents energy analyses of thermal power generation plants such as coal. oil and LNG. The input energy of power generation technology is estimated not only for the construction materials of the power plant but also for all fuel processes in mining, refining and transporting to a power station. Net and gross energy analyses on the power plants are calculated using the input and output energies of a generation plant. The analyzed net energy ratio of an LNG plant is one-third that of oil or coal plants, because it consumes a large amount of energy; approximately 10 to 15% of LNG production on the extraction, refining and liquefaction processes. Excellent liquefaction and re-gasfication processes are expected to be realized with the knowledge of cryogenic engineering.
