Conclusion

This article illustrates some examples of LCA studies in electrical engineering, and more specifically in the manufacture of metals, permanent magnets, static converters, electrical machines for traction, electrochemical batteries and photovoltaic systems. An example of eco-optimization has also been proposed for a home automation application. Depending on how a component is used, and how long it lasts in relation to its assigned useful life, the manufacturing and dismantling phase can weigh heavily on the overall environmental balance. For intensive use, operating losses are a determining factor, but this requires a detailed analysis of service life and repair solutions. Conversely, for moderate or occasional use, manufacturing and resource consumption represent the main impact, which means that recycling objectives need to be integrated right from the design stage.
