Abstract Biogas energy is a flexible renewable energy source that can be used as a substitute for fossil fuels. The objective of this thesis is to compare the technical efficiency (TE) between biogas and conventional farms in Egypt. Data was collected via face to face interviews with the farmers, a sample of 200 farms divided equally between biogas farms and conventional farms. Results showed that biogas farms are more technically efficient and more profitable than conventional farms. Different factors are found to affect TE levels such as farmer experience and their environmental conservation attitudes preferences. Farmers with more experience will be more TE that is TE increases with skills and practice of farmer. The results also show that TE cannot be affected by farmers{u2019} preferences. The variance parameters of the likelihood function are estimated and the y is close to zero, the deviations are mainly due to noise and the average response production function is an adequate representation of the data. TE scores for conventional and biogas farms are calculated as an output-oriented |
