Planting jatropha curcas and developing jatropha diesel is one of major approach to resolve the nowadays energy and environmental difficulties. Jatropha curcas can grow on a lean soil and absorb carbon dioxide to ease the global warming anxiety. Its seeds are oil rich and can extract bio-diesel fuel to provide a substitute fuel. For this reason, planting jatropha curcas and extracting jatropha diesel are booming business internationally. Outside Taiwan, especially in Africa and Asia, many massive planting jatropha curcas projects are put forward. Nevertheless, it has very few meaningful projects ongoing in Taiwan. 　 　　Our research of planting Jatropha curcas in Miaoli County, Taiwan, which encompass of growing seedlings, transplanting, nurturing, reckoning its sprouting rate, surviving rate, tree height, fruitage percent and etc. Our results show 80.5% germination percentage, 94% sapling transplant surviving rate, and 21% fruitage tree count and 3~19 capsules per tree. The seeds harvest 3,024 kgs per hectare in the 3rd year, and the seed oil content is 35.1％. The annular planting cost is NT$ 56,264 per hectare, and the harvested jatropha seed cost is NT$ 18.6 per Kg. The refined biodiesel cost is NT$56.5 per liter, which is lower than the biodiesel from domestic soybean, sunflower seed, and rapeseed. 　 　　These preliminary results are comparable to the foreign growing statistics or even better and indicate jatropha curcas are suitable to be grown in Taiwan, worth to be popularized and apt to develop jatropha biodiesel fuel. Its benefits include absorbing carbon dioxide gas, reducing greenhouse effect, substituting fossil fuel, easing energy shortage crisis and, in the mean time, raising Taiwan energy autonomous rate. 　 　　The suggestions for the biofuels develop in Taiwan: carefully selected appropriate energy crops, government incentives grow and produce biofuels, and controlledthe marketing channels.
