How big is the influence of elevator appliances

The famous financial Journal CFO has found two surprising discoveries on 1000 large American companies.
First: electricity expenditure is usually the third or fourth largest cost of an enterprise.
Second: for most enterprises, the electricity fee is the last cost that is not controlled by the enterprise.
According to the research, it shows that at least 20% of the expenses can be reduced by a series of technology and management measures. At the technical level, it is usually possible to reduce the power consumption of the equipment by adding an advanced power saving control device on the side of the equipment, such as the installation of an advanced power saving control device. A series of mature power saving methods can greatly reduce the power consumption of different electrical equipment, such as motors, lights, air conditioners, compressors and even a power consumption system. There is a great potential for this and a mature, proven means to choose.
The cost control of electricity cost has become the last cost control place of large companies in the United States. It is an uncontrolled cost and the last controllable cost of an enterprise.
This can be seen as the last cost of uncontrolled large enterprises. Once someone decipher the mysteries of this technology, it will lead the trend of a new technology. Elevator as a large enterprise is always using electrical appliances, if there is elevator electric saver, once used, will inevitably lead to the trend of the economic industry. The first person to apply for the patent may be the next Bill Gates, and it can see how powerful the elevator is.
