The Department of Energy addresses the Nation's energy, environmental, and nuclear challenges, using transformative science and technology to ensure national security and prosperity.


On August 4, 1977, President James E. Carter approved Public Law 95–91, which also is cited as the "Department of Energy Organization Act." President Carter made remarks about the new law (S. 826) on the same day that he approved it.

The President's remarks on signing S. 826, which also is cited as the "Department of Energy Organizational Act," were included in the "Public Papers of the Presidents of the United States." The public papers of "Jimmy Carter" for the year 1977 are collected in two books. Book II (25 JUN–31 DEC) is available on the Government Publishing Office's govinfo website in Portable Document Format (PDF) for downloading. The relevant section of the remarks is found on pages 1411 and 1412.

The new statute consolidated the major Federal energy functions into one Cabinet-level department. It established "a Department of Energy in the executive branch by the reorganization of energy functions within the Federal Government in order secure effective management to assure a coordinated national energy policy" (91 Stat. 565).

On September 13, 1977, President Carter signed Executive Order 12009, which was published 2 days later in the Federal Register (42 FR 46267). Pursuant to the order, the Department of Energy Organization Act became effective on October 1st of that same year.

By the advice and with the consent of the Senate, the President appoints the Secretary who serves as the top administrator at the Department of Energy.

The "Offices" web page provides convenient access to information on DOE offices, centers, power administrations, and component agencies, as well as to online resources that are associated with some of them.

On the "About Us" web page, below the contact information, a hyperlink for the DOE's organization chart is available. The organization chart also may be viewed in Portable Document Format (PDF) and downloaded as a PDF file.


Title 42 of the United States Code (U.S.C.) is dedicated to the topic of "The Public Health and Welfare." Statutory material that affects the Department of Energy has been codified and assigned to Chapter 84 of 42 U.S.C. Chapter 84 runs from sections 7101 to 7385s-16.

Rules and regulations that address the topic of energy have been codified and assigned to Title 10 of the Code of Federal Regulations (10 CFR 1–1899).

Rules and regulations that are associated with the Department of Energy have been assigned to Chapter II of 10 CFR.

Additional rules and regulations that are associated with the Department of Energy have been assigned to Chapter III of 10 CFR.

The general provisions of the Department of Energy have been codified and assigned to Chapter X of 10 CFR.


In 2022, the DOE will mark its 45th anniversary. The DOE is a cabinet-level department whose activities and programs are as important as they are diverse. The DOE brought together for the first time, within one Federal agency, two programmatic traditions that had coexisted within the Government. One tradition constituted the defense responsibilities that included the design, construction, and testing of nuclear weapons originating with the effort to build the first atomic bomb during the Second World War. The other tradition comprised a loose amalgamation of energy-related programs that were scattered throughout the Federal Government. The presence of these two traditions remains palpable in the range of activities and programs of today's DOE.

Energy Economy

The national economy benefits from robust investments in energy technologies. These investments stimulate the creation of new jobs. The DOE both supports proven energy technologies and funds and promotes energy technologies of the future. It also partners with private- and public-sector organizations to spread and accelerate the implementation of these technologies.

The DOE guides legislators and policymakers through the complexities and details of energy related issues. It serves as a liaison among Federal agencies, Members of Congress, and State, local, and tribal governments. It also assists American Indian Tribes and Alaska Native villages with energy development, capacity building, electrification of lands and homes, and reducing energy costs.

Research / Innovation

The DOE is aptly described as a research and science agency that participates aggressively in the innovation economy. The Department stimulates the growth of basic and applied scientific research and the discovery and the development of new clean energy technologies. The DOE regards scientific innovation as a cornerstone of the Nation's economic prosperity and, therefore, prioritizes innovation in its research and science programs. It also fosters collaboration and cooperation among governmental organizations, industries, and universities to create a capacious scientific ecosystem and to invigorate it.

The DOE's Loan Programs Office finances comprehensive and large-scale energy infrastructure projects nationwide.

The Advanced Research Projects Agency–Energy (ARPA–E) supports the development of energy technologies that have high potential and broad application before they are ready for investment from the private sector.

The DOE's 17 National Laboratories serve as regional drivers of economic growth for States and communities nationwide. Among the world's science institutions, the National Laboratories constitute a unique ecosystem of intellectual assets and pooled knowledge.

Safety / Security

The DOE helps to protect national security. Its responsibilities include cleaning up the adverse environmental consequences of developing nuclear weapons and of nuclear energy research, supporting nuclear nonproliferation, ensuring the security of the Nation's nuclear weapons stockpile, providing training tools and procedures for emergency response and preparedness, managing the Strategic Petroleum Reserve, investing in protections against cyber and physical attacks on energy infrastructure, and conducting programs to ensure worker health and safety.

The DOE safely and cost-effectively transports and disposes of low-level wastes, decommissions and decontaminates old facilities, remediates contaminated soil and groundwater, and secures and stores nuclear material in stable and secure locations to protect national security.

The National Nuclear Security Administration ensures the integrity and safety of the Nation’s nuclear weapons, advances nuclear nonproliferation, and promotes international nuclear safety.

The DOE works closely with its public and private sector partners to secure the Nation’s critical energy infrastructure against all hazards, to reduce the risk of disruptive events, and to respond to energy disruptions that could jeopardize national security, public health and safety, and the national economy. DOE response activities include hurricane response, extreme weather and wildfire response, and cyber incident response.

The DOE has continency plans for mitigating the effects of extreme petroleum supply interruptions. The Office of Petroleum Reserves (OPR) acquires, stores, distributes, and manages emergency petroleum stocks. The OPR maintains the operational readiness of three emergency stockpiles: the Strategic Petroleum Reserve, the Northeast Home Heating Oil Reserve, and the Northeast Gasoline Supply Reserve (NGSR). In the event of a natural disaster or other national emergency, the Nation can draw from these emergency stockpiles to keep crude oil and other petroleum products in steady supply.

The DOE leads the Federal Government’s effort to mitigate the potentially catastrophic effects of cybersecurity attacks on the energy sector. It also ensures the cybersecurity and resilience of all energy infrastructure that is associated with the DOE enterprise.

DOE health and safety programs help to protect workers and the public from the hazards associated with departmental operations. Former and current DOE Federal, contract, and subcontract workers benefit from health and safety policies, program tools, and assistance resources.

The Energy Employees Occupational Illness Compensation Program Act (EEOICPA) provides compensation and medical benefits to employees—including contractors, subcontractors, and some vendors—who worked at certain DOE facilities. The Department of Labor (DOL) handles the adjudication of issues involving all claims for benefits under the EEOICPA . Alongside the Departments of Justice (DOJ) and Health and Human Services (HHS), the DOE supports the DOL as it adjudicates these issues.

Saving Money / Lowering Energy Consumption

The DOE maintains a website that is dedicated to helping consumers to use energy more efficiently and to adopt renewable forms of energy. These consumers include builders and renovators, commuters and drivers, families, homeowners, landscapers, and renters. Energy Saver is the DOE's premier consumer resource for ideas on how to lower energy consumption and save money and for learning about renewable energy technologies that are applicable at home.

Sources of Information

Analysis / Statistics

The U.S. Energy Information Administration is the statistical and analytical agency within the DOE. It is the Nation's premier source of energy information. By law, its data, analyses, and forecasts are independent of approval by any other officer or employee of the Federal Government.

In 2020, the DOE ranked 11th among 25 midsize Government agencies in the Partnership for Public Service's Best Places To Work Agency Rankings.

Climate Change

Mitigating the effects of climate change is on the DOE's top-priorities list. Global temperatures continue to rise; therefore, drought, heat waves, wildfires, and high demand for electricity will put additional stress on the Nation's energy infrastructure. The leading cause of power outages and fuel supply disruption in the United States is severe weather. As the Earth System continues on this current heating trajectory, Climate scientists predict that severe weather events will become more destructive and disruptive. Visit the "Climate Change" web pages to learn more about how the DOE is responding to this growing threat.

The Energy Exascale Earth System Model (E3SM) Project is a state-of-the-science Earth system modeling, simulation, and prediction project. Relying on DOE laboratory resources, the E3SM Project helps to meet the science needs of the Nation and the mission needs of the DOE.

Title 10 of the Code of Federal Regulations (CFR) is dedicated to rules and regulations that are associated with energy. Chapter II of that title is dedicated to the "Department of Energy." Subchapter B, which runs from section 300.01 to 300.13, is dedicated to "Climate Change."

A very important development in the field of biology within the past 100 years was the Human Genome Project (HGP), the 10-year Government-led effort that culminated in the first complete sequencing of a human genome in 2000. The HGP launched the field of genomics, transformed medicine, and pretty much birthed the modern biotechnology industry. The original idea and impetus for the HGP came from the DOE's Office of Science, which was then known as the Office of Energy Research. At the time, the sequencing of a whole human genome was considered a nearly impossible task. With the historical experience of large scientific endeavors that had started with the Manhattan Project, Office of Science personnel had the confidence that the task could be accomplished with sufficient Government resources. Interest in better understanding the genetic effects of radiation exposure stimulated the DOE's initial interest in undertaking this bold initiative.

The Federal Energy Regulatory Commission helps consumers obtain efficient, reliable, and sustainable energy services at fair and reasonable rates through regulatory and market means.


The Federal Energy Regulatory Commission (FERC) is an independent agency within the Department of Energy that regulates the interstate transmission of electricity, natural gas, and oil. The Commission comprises five members whom the President appoints with the advice and consent of the Senate. FERC Commissioners serve 5-year terms and have an equal vote on regulatory matters. The President designates one member to serve as both the Commission's Chair and its administrative head.

An organizational chart and brief descriptions of the main activities of each office are posted online.


Under the authority of the Federal Power, the Natural Gas, and the Interstate Commerce Acts, the FERC regulates the interstate transmission of electricity, natural gas, and oil. That authority also includes review of proposals to build interstate natural gas pipelines, natural gas storage facilities, and liquefied natural gas terminals, and licensing of nonfederal hydropower dams.

The FERC enforces regulatory requirements by imposing civil penalties and other means, monitors and investigates energy markets, and protects the reliability of the high voltage interstate transmission system through mandatory reliability standards.
