In addition, factors such as wind resistance reduce overall system efficiency.

Some fans use brushless motors also in order to increase overall system efficiency.

With the jump to all electronic logic, physical presence was no longer needed and the individual control points could be consolidated to increase system efficiency.

By 1968, system efficiency had reached 85% by recycling water.

These benefits can be achieved with little effect on overall system efficiency.

The following chips can be used to enhance system efficiency:

Current research in the area aims at increasing the system efficiencies while keeping the system cost low.

This limit sets the upper limit for the system efficiency.

The overall system efficiency would then drop to 25%.

This lower voltage drop can provide higher switching speed and better system efficiency.
