Since you are from zoology field you will not find any applications in this stream. MBA in Energy and Environment includes technical knowledge and engineering applications too. If you had a degree of B.Sc in environment science you can apply. Also the companies would find difficult to hire you and provide you a profile due to your different specialization as compared to others in a batch. So I would recommend you to choose another stream which is related to zoology instead of E&E.
