The U.S. Energy Information Administration (EIA) collects and publishes data at different geographic levels (depending on the data series):
- Census region or division
- State or U.S. territory
The State Energy Portal is the main area on EIA's website to find state energy information. The State Energy Portal is home to EIA's State Energy Profiles and EIA's State Energy Data System. The portal also features state rankings for 10 key energy statistics, provides a search function that allows users to find EIA's state data easily, and provides users with the ability to compare state energy data along a variety of data points and energy indicators.
One of the most popular features on EIA's website is the State Energy Portal's multilayer mapping tool that provides user-selected views of fossil fuel and renewable energy resources, oil refineries, pipelines, power plants, transmission lines, and other energy infrastructure for the United States. Each individual state page contains a state map.
State energy profiles
State Energy Profiles summarize all of EIA's state-level and fuel-specific energy data for each state. Each profile, which can be printed as an integrated report, is updated monthly and includes several features:
- Data tables with about 90 key state-level data items, updated monthly
- Quick facts that present noteworthy state energy facts in bulleted form
- Analytical narratives that explain how fossil fuels, nuclear energy, renewable energy, energy infrastructure, and energy-related activities interact in each state's energy markets
- Downloadable charts that provide an overview of state energy production, consumption, as well as context to state energy prices
- Related links that give users quick access to additional state energy resources
- Notes and sources that offer reference material on state energy data and facts
State Energy Profiles also include data and information for five U.S. territories:
State Energy Data System
The State Energy Data System provides annual time-series estimates of state-level energy consumption, prices, expenditures, and production. The full set of tables and data files are updated annually.
The estimates provide multi-dimensional information for the following:
- Concepts: Consumption in physical units and British thermal units (Btu), prices in dollars per million Btu, expenditures in million current dollars, and production in physical units and Btu
- Energy sources: Coal; natural gas; 10 major petroleum products, other petroleum products, and total petroleum; nuclear fuel; renewable energy, including hydroelectric power, geothermal energy, solar energy, wind energy, and wood and waste; and total energy
- Consumption sectors: Residential, commercial, industrial, transportation, electric power, and total
- Geography: 50 individual states, the District of Columbia, and data for the United States as a whole
- Time periods: Consumption (beginning in 1960), prices (beginning in 1970), expenditures (beginning in 1970), and production (beginning in 1960)
