Clean and Efficient

摘要

The European Union's voluntary Motor Challenge Program is a leader in encouraging electric motor manufacturers to increase efficiency. Originally formed to address emissions that may be causing climate change, the group picked up momentum with the dramatic rise in energy costs over the past few years.Motor Challenge organizers estimate that all electric motors used in industry and buildings account for up to 30 percent of total energy consumption. The motors and the pumps, fans, compressors, and other equipment they power are already highly efficient. Yet Motor Challenge estimates that changes in system design, operation, and maintenance could improve efficiency by 20 to 50 percent.
