Did you ever hear the expression, “work smarter, not harder”? That’s what many people think that our electrical grid should do.
Why It Matters
- An electrical grid is a network of power plants, transmission lines, substations, transformers, and other devices that deliver electricity from power plants to consumers.
- In the U.S., the electrical grid includes more than 9,000 power plants and about 300,000 miles of transmission lines. You connect with the grid whenever you plug in a phone charger or turn on a light.
- The current U.S. grid was designed over a century ago. Back then, people had few electric devices, so power needs were low. Today, the U.S. electrical grid is overworked, inefficient, and plagued with problems.
