In fact, the German Federal Environment Agency calculates that the use of more efficient drive control and motor technologies could lower consumption by approximately 27 billion kilowatt-hours by 2020 in Germany alone, eliminating around 16 million metric tons of CO2 emissions in the process1. The European Union has also recognized this enormous potential, leading it to start its own initiatives designed to promote more environmentally friendly product designs. The core of this new approach is Directive 2009/125/EC for energy-related products, more commonly known as the ErP Directive2. This directive establishes a framework for defining ecodesign requirements within the EC for products relevant to energy consumption. It also specifies a series of criteria that these products must meet before they can be operated within...
