Power grid security

How safe is the US power grid?

FOX 11 is digging deeper into the safety of the U.S. power grid. As we've reported this week, some people say it could be a target for terrorists.

From charging your cellphone to keeping your food cold, electricity is part of our everyday life - something that most people could not live without.

It's delivered through a network of power plants and transformers. Connecting it all: more than 450,000 miles of high-voltage transmission lines. From there, the power is delivered through a series of small, low-voltage lines, allowing you to power up your electronic devices and appliances in your home.

And because of our reliance on electricity, some counterterrorism experts believe the U.S. power grid could be a potential target.
