タイ王国におけるバイオマス燃料についての認識についての調査

摘要

地球温暖化緩和のために二酸化炭素（CO_2）排出量の抑制が強く望まれており，エネルギー消費起源のCO_2排出を削減するために，再生可能エネルギーの導入促進に期待が寄せられている。バイオマスエネルギーは液体燃料が得られるという，他の再生可能エネルギーが直接的には満たしていない特色がある。%Biomass energy systems are expected to be useful for making low carbon society. For the wide spread of biomass energy systems, acceptance by the consumers is important, but recognition for them by the public is obscure at present. It has remarkable feature of supplying liquid fuel which can be used traffic energy without thoroughgoing modifications of transportation systems. We launched a social survey to investigate the perception of biomass fuels in Kingdom of Thailand and the responses were analyzed with conjoint analysis. Subjects were asked to choose their favorite petrol for their car from four alternatives of fuels with attribute of percentage of alcohol, material crops, unit costs and CO_2 reduction rate. The analysis proved that sugar canes and cassavas are favored than rice straws for raw materials. Alternatives with larger amount of CO_2 reduction were preferred and high cost alternatives were avoided. Effects of respondent characteristics on choice behavior were also analyzed
