Smart grid

Published on

A Smart Grid is an electrical grid that uses information and communications technology to gather and act on information, such as information about the behaviors of suppliers and consumers, in an automated fashion to improve the efficiency, reliability, economics, and sustainability of electricity production and distribution. Just as ICs were used to improve the bandwidth of copper cable, they can also be used to improve the bandwidth of electrical cables. These improvements enable a Smart Grid to more effectively purchase and distribute electricity and provide users with real-time prices including time of day prices.
