This study was conducted to investigate energy value of jojoba seeds obtained from plants cultivated in Jordan. Solvent extraction was employed with different extraction solvents (polar and non polar). The oil yield was recorded for different time spans. The physicochemical properties of the extracted oil including: acid value (AV), saponification value (SP), iodine value (IV), peroxide value (PV), viscosity, density, heating value and ash content were investigated. The energy value of the seeds after oil extraction (Jojoba rest) was also evaluated. The results showed that hexane gave the highest oil yield at 58.76% with a sufficient extraction time of 30 min. The measured properties of jojoba oil suggest the possibility of a single step base catalyzed transesterification process for biodiesel manufacturing with high yield. Moreover, it was also found that the remains of the seeds after oil extraction (Jojoba rest) have a heating value of 15. 344 MJ/kg and thus it can be used to replace solid nonrenewable fuels in certain cases. https://www.researchgate.net/publication/257828202_Investigating_the_Energy_Value_of_Jojoba_as_an_Alternative_Renewable_Energy_Source
