Abstract
A mathematical model of the relationship between biogas energy potential obtained from animal waste in Thailand by simple linear regression analysis was generated from data classified by province in 2020. The study found that the biogas energy potential was related to animal waste with a correlation coefficient of 0.9966 and could predict biogas energy potential at 99% (p < 0.001) with a standard error in the forecast equal to ±0.36: the forecast equation for the relation between biogas energy potential (y) and animal waste (Xi) was y = 0.0535 + 0.00002xi. The model was verified by comparing its predictions for 2021. The obtained model will be useful in future planning policies for the use of biogas renewable energy.
