The energy consumption worldwide by the industrial sector is expected to keep increasing during the coming years; generating greenhouse gas (GHG) emissions as unwanted byproducts. For that reason, industrial facilities must take concrete initiatives in order to decouple their production growth from their CO2 emission generation in order to decrease their contributions to global warming. Concerned that this is a world-wide problem, Mexican maquiladoras have started several energy-efficiency initiatives. This article present the results of a descriptive and analytical study that has been conducted during the two first stages of the framework of the Cleaner Production Program focused on Energy Efficiency by the United Nations Environment Programme. Findings reveal that, although electrical devices seem work efficiently; it is still possible to address energy waste. It was also found that attaching the energy-efficiency approach to the cleaner production framework is a complicated task because, unlike emissions and toxic residues, energy inefficiencies are not easily visible, verifiable, or measurable.
