How to improve efficiency of power transmission and distribution system?

You can improve the efficiency of transmission and distribution system by reducing energy losses from the resistance of the power lines.This can be done by using higher transmission voltages and increasing the wire sizes of tramsmission lines,which could also mean more investment. Transmission and distribution lines has to be properly selected that your investment could equal the energy lost in a definite period of time.
