Abstract The poultry industry is important and consumes a large amount of energy. The main objective here is to study the proportions of renewable energy that can be produced from poultry waste and use it inside poultry farms. A mathematical model consisting of algebraic equations was processed by MATLAB program and developed for heating broiler house by exhaust gas from generator engine. The results show good agreement between predicted and measured values where about 19.85 kWh day−1 of electricity can be generated from the broiler waste and 32.28 kWh day−1 of waste heat energy is recovered from generator exhaust gas. The results concluded showed that energy losses by transmission were 49%. Therefore, the thickness should be increased to reduce this percent. The moving insulating wall saved 200% and 100% of energy in the first and second stages of the breeding cycle respectively. About 44% of the lost energy was due to ventilation. Therefore, the ventilation process should be carried out through heat exchangers to keep the energy. Fermentation of farm waste to produce biogas and use it in the farm met about 49% of the farm’s energy needs.
