However, the establishment of more power plants also produces a lot of environment problems such as the nuclear waste proceeding, sour rain and the green house effect caused by the air pollution. It has become the top mission for power industries to protect environment as well as to increase power supply. Cooperation with Committee of International Atomic Energy Agency and other nine organizations, DECADES was developed for the planning of power industries. With the technologies of multi-objective and fuzzy planning in DECADES, it is the object of this paper to find a suitable power plant technology for our country by implementing this software. Power plants have different characteristics on their costs, air pollution, and machinery layout because of the use of different energy sources. The analysis through DECADES shows both the gas and nuclear power generating technologies will better fit our demands than other technologies under the strict green house air emission control regulation lay down by "Kyoto Protocal". But if taking radioactive material into consideration, nuclear power plant is no longer in advantage. In Taiwan, the cost of natural gas is much higher than that in many other countries since it is mostly imported, which reduces the competitiveness of gas power plant. For coal fired power, the cost is lower but it is also controversial as it emits more air pollute materials than other power generation technologies. In terms of pollution control and cost consideration, oil-generated power is a better choice than coal fired power, and gas power. If the pollution material emitted could be further reduced and the costs could be further down, oil-generated power would be a good alternative. The report is conducted on basic version of DECADES so the compression could be only on the power plant level. It is incapable of further, detailed analysis on the chained-level analysis, impact on outside environment and the back-end cost. Should advanced version of DECADES be obtained, it is hoped more objective, effective evaluation could be conducted on different power generation.
