Electricity

The Department of Energy (DOE) plays a central and expansive role in all aspects of electricity in the United States, from generation and transmission to research and efficiency. Created in 1977 in the aftermath of the 1973 oil crisis, we oversee national energy policy and production, aiming to ensure an affordable, reliable, and secure supply of energy.

Electricity in the United States

Electricity powers homes, businesses, and critical infrastructure across the United States. Generated from a range of energy sources and delivered through the electric grid, it supports daily life, economic activity, and public safety. The Department of Energy works to strengthen grid reliability, improve resilience, and support innovation across the electricity sector.  

How the Electric Grid Works

Electricity moves from power plants to homes and businesses through a network of transmission lines, substations, and distribution systems known as the electric grid. This system must constantly balance supply and demand to ensure reliable service. Operators monitor the grid in real time to maintain stability and respond to changes in usage, weather, and system conditions.
