Abstract Foundry is one of the most energy intensive metallurgical industries. In Uganda foundries are associated with large energy consumption necessitating the need to seek for ways to minimize their energy consumption. This study sought to establish the energy efficiency of the SMEs in Uganda with the view of devising means to reduce on their energy consumption. This was accomplished by studying the energy consumption trends in the industry using primary and secondary data obtained from a number of SME foundry operators in Uganda and basing on this data energy efficiency and conservation measures have been devised. The major energy sources used in these foundries include used oil at a consumption rate of 72 biomass charcoal and firewood at 21 diesel at 6 and electricity at 1. The specific energy consumptions SEC of the firms studied range from 7.35 MJkg to 14.61 MJkg which is considerably on the higher side. The melting process consumes the biggest part of the total energy consumed at 70 in the foundries. This necessitates the employment of more energy efficient melting technologies. Implementation of energy management programs in order to reduce energy requirements per unit of output is thus recommended. Different energy saving measures that can be employed in this sector were identified. Some of these can be implemented by adopting simple courses of action while others require high capital investment. It is thus recommended that these firms start by implementing the low cost solutions and progressively move to the capital intensive solutions.
