Energy efficient motors - Saving money or costing the earth? Part 2

Part 1 of this article (February 1999 PEJ, p.25) outlined the importance of improving electric motor efficiency as a means of reducing environmental p ollution and described how the production cost of higher efficiency motors could be reduced by an holistic approach to motor design. However, environm ental pollution will only be reduced significantly if a majority of motor m anufacturers take steps to improve the efficiencies of their products. Part 2 of this article describes the various regulatory measures which have bee n, are being, or may be taken to encourage a market transformation.
