Drives can save an average of 40% of the electricity a motor uses as well as reduce related CO2 emissions. Since industry accounts for one-third of the world’s electricity consumption and electric motors consume 65% of industrial electricity in regions such as the EU, the potential global energy savings from a wider use of drives would be substantial. For an industrial enterprise drives can reduce energy costs, minimize wear on motors and other equipment, and reduce maintenance costs. For factories, buildings, and utilities, Delta’s MVD1000 & MVD2000 medium voltage drive can save energy significantly.
