The U.S Energy Grid is a network of transmission lines that allow energy suppliers to power homes, offices etc. There are three interconnected systems in the USA that provide electricity to the country. High voltage distribution lines deliverelectricity from power stations to the populace.
The Energy Grid Infrastructure:
The Grid has four major components: electricity generators, transmission lines, distribution networks, and consumer use. The individual generators in the Grids is where the energy is created. Energy can be created using different types of generators/power stations, They can be powered by coal, natural gas, or be hydroelectric. Transmission lines carry the energy produced to the populace. Homes, businesses etc are at the end of the grid.

Smart Grid:
The Smart Grid is an electric grid that relies on technology to supply electricity. The electric grid would be upgraded to not operate at one capacity. It would increase effeciency becaue energy would be provided as needed. There are enough sensors, lines of communication and data points between the grid & populace to allow the grid to provide power on demand.
Below are a list of pors and cons of building a smart grid.
Pros:
- Efficient & environmentally friendly grid.
- Quicker recovery from a blackout.
Cons:
- Extremely high cost.
- Potential for cyber terrorism.
