The main purpose of an energy audit is to systematically identify, using calibrated measuring instruments, the level of energy consumption and to investigate practical and feasible opportunities for saving all forms of energy costs. Experience show that as much as 10-15% of energy costs could be saved without any need for large investment on energy reducing measures.
Energy inpuis (both electrical and fuel) are essential parts of any manufacturing process. The expenditure on these inputs often accounts for a significant share of the manufacturing costs. As such, any savings on electrical and fuel costs adds directly to the profits of the company and these probably require less effort to impact profits than other measures such as reducing labour costs, increasing sales or lowering distribution costs.
