The United States is facing some serious issues with its electricity grid. The infrastructure was established more than a century ago, before the Internet or cellphones or a lot of renewable energy generation. It simply wasn’t equipped to handle today's electricity load. Though the entire infrastructure represents a way of distributing electricity that's more than 100 years old, the grid has seen some updates along the way. But unfortunately, some parts of the grid haven't gotten a modern touch in more than 50 years. This leaves the electricity system vulnerable to rolling blackouts or even terrorist attacks. Many believe the grid needs a complete overall to function properly for America today.
