Many industries depend on energy-intensive machines and processes. Ball mills and kilns in cement plants are good examples. There are also many energy-intensive applications in food and chemical industries.
While established energy efficiency measures are often highly expensive, specialty lubricants can offer a simpler and relatively low-cost way to significantly reduce energy costs; yet this opportunity is often overlooked or underestimated. This is partly because energy efficiency optimisation through lubricants, and its quantification or monetary proof, is not simple or easy to demonstrate – and the entire system must be considered. Then, the only true proof that better lubrication has reduced energy consumption comes from before/after comparisons.
