Abstract
This thesis has two main goals: (i) focusing on evaluating the Energy Ecological Footprint（EEF） from 1990 to 2003 in Taiwan under Ecological Footprint Theory, (ii) aiming at analysis of the interaction among energy consumption, economic and ecological pressure, and (iii) further establishing the Energy-Economic Modeling to measure sustainability of both as well as energy efficiency.
Research results are presented in four types as:
(i) EEF
EEF per person from 1990 to 2003: 1.46 ha in 1990; 1.61 ha in 1991; 1.68 ha in 1992; 1.77 ha in 1993; 1.87 ha in 1994; 1.93 ha in 1995; 2.01 ha in 1996; 2.13 ha in 1997; 2.22 ha in 1998; 2.33 ha in 1999; 2.47 ha in 2000; 2.57 ha in 2001; 2.71 ha in 2002; 2.78 ha in 2003. Moreover, EEF of Taiwan is more than that of global called by “overdraft”.
Accounting EEF by energy types: liquid fossil fuel has occupied 60.64%; coal has occupied 22.25%; fossil gas has occupied 13.32%; nuclear energy consumption (thermal) has occupied 3.72%; hydro-electricity consumption has occupied 0.07%。
(ii) Ecological Pressure
Year 2003 is the highest by assessment of Energy Footprint to Ecological Pressure Intensity (EFEPI ); in other words, we need 16.37 times as Taiwan areas in the present.
(iii) Energy- Economic Efficiency Modeling
Year 1995 and 1996 are the best two, but 2003 is the worst by assessment of Production Ratio to Energy Footprint (PEFR).
Among of 23 high income nations (GDP more than 9266US$) of PEFR, Norway is the top in 1996 and 2001 ; Swissland is the top in 1999. However, Taiwan’s ranking of PEFR is the 12th in 1996; 18th in 1999; 15th in 2001.
(iv) In addition, this research has established the Marginal–Most Sustainable Development Economic-Energy Modeling, MMSDEE=0.493e3E-05x x=GDP) for measuring energy efficiency.
Finally, this study has found that year 1997 is the critical point of Taiwan’s toward sustainability / unsustainability during 1990 and 2003; from then on, energy , economic and ecological environment are getting decreasing.
