View hourly electricity demand and generation across the continental US

A dashboard showing real-time electricity usage in the US

The United States demands for electricity are enormous, with hundreds of thousands of megawatt hours required to run households and businesses every hour. You can track the fluctuations of US electric use with this dashboard.

These are made up of utilities, Power Marketing Administrations—hydropower marketers from the Department of Energy—and groups of utilities that have formed regional entities called Regional Transmission Organizations or Independent System Operators. Collectively, balancing authorities ensure supply meets demand and can direct utilities to implement rolling blackouts to prevent permanent damage to electrical equipment.

These charts show how the shares of generated electricity sources—solar, wind, hydro, nuclear, bioenergy, oil, gas, and coal—have changed since 1985. Since 2010, an increase in renewable sources has offset the share lost by nuclear and fossil fuels.

Simulate the effects of changing supply and demand on the electric grid

In this application, users can modify the demand of fictional cities and the supply of various generators, including a nuclear power plant and a wind farm, which can be disconnected from the grid. Notice that current may flow into or out of external systems to compensate for available generation. See what it takes to cause a blackout in different cities or shut down the entire grid.

View a distribution of wind turbine locations across the US

As of May 2025, the US Wind Turbine Database maps and provides technical specifications for 76,051 onshore and offshore turbines from 1,794 projects, ranging from small installations to large-scale wind farms.

Larger shares of solar power generation produce larger energy demand curves

Because solar energy is only available during daylight hours, transitioning an electric grid to solar requires significant ramp-ups and ramp-downs of other energy sources during mornings and evenings to compensate. Widespread adoption of affordable energy storage solutions can soften these curves.

The history of the North American power grid, which is composed of five major grids

Thomas Edison's Pearl Street Station was the first US commercial power plant, burning coal to power lamps for some Manhattan residents. Over time, local power plants would be bought out by larger ones, forming interconnected systems spanning multiple states. Today, the Eastern Interconnection and Western Interconnection are the largest of these systems.

See where the 94 nuclear reactors in the continental US are located

In 2023, these reactors—located in 53 plants across 28 states—prevented 437 million tons of carbon dioxide emissions. A single fingertip-sized uranium pellet generates as much electricity as a ton of coal, enough for one household's annual electricity.

Electrical grids worldwide must double their power delivery capacity by 2050 to meet surging demand from AI and electric vehicles.
