Energy is a multiplying factor which allows man to translate various raw material and resources into useful items to meet the daily demands and necessities of human beings. Foundry technology involved casting from molten metal transferred into a mould and permitted to harden under varying conditions depending on the purpose. This paper reviews the foundry industry as an energy exhaustive industry, in the sense that it requires energy in various forms such as electrical, heat and mechanical to carry out various engineering processes to deliver the appropriate casting required. It also reviews the different methods are currently being employed to make the manufacturing process more efficient and each of them have led to an increase in energy demand. It is affirmed that the new methods involved in foundry and their energy management policy can led to more efficient energy consumption for casted product.
