Explanation:

Before you lament the price of electricity, imagine life without it. Candles and lanterns would light your way, you'd keep food cold using ice, and every electronic device you ever plugged into a wall socket would no longer work. However, with the immense benefits that electrical power provides come some disadvantages besides cost.

The Joy of Electrical Current

Hospitals, police, armies and governments rely on electrical power to assist, protect, govern and communicate. Electrical power is so important that the White House noted in a 2012 blog post, "protecting the electric system from cyber threats and ensuring its resilience are vital to our national security and economic well-being." The nation's electric grid consists of 450,000 miles of transmission lines connecting transformers, power plants and consumers.

AC vs. DC: Power Transmission Becomes Economical

In 1882, the country's first power plant relied on direct current, or DC, in which electricity flows in one direction. In the late 1800s, Nikola Tesla and George Westinghouse helped pioneer alternating current, or AC, technology. Moving in two directions, AC makes it possible for power plants to transmit power long distances at costs cheaper than if they were using DC. Today's power plants supply AC electricity to homes and businesses around the world.
