The United States Department of Energy (DOE) is a part of the U.S. federal government. It helps manage the country's energy. The DOE works on many important things. These include creating energy plans, producing energy, and researching nuclear power. It also handles the military's nuclear weapons program. The DOE helps make nuclear reactors for the United States Navy. Plus, it supports research related to energy and promotes energy conservation.

The DOE was started in 1977. This happened after the 1973 oil crisis when there were problems with oil supply. The DOE supports more science research than any other U.S. government agency. Much of this research happens at its National Laboratories. The DOE also leads research in genomics, like the Human Genome Project.

The head of the department is the Secretary of Energy. This person reports directly to the president of the United States. The Secretary is also a member of the President's Cabinet. The current Secretary of Energy is Chris Wright. He started in this role in February 2025. The main office of the DOE is in Washington, D.C.. It is located in the James V. Forrestal Building. There are also other offices in Germantown, Maryland.

How the Department of Energy Started

Early Beginnings and Growth

In 1942, during World War II, the U.S. Army started the Manhattan Project. This project was created to develop the atomic bomb. After the war, in 1946, the Atomic Energy Commission (AEC) was formed. Its job was to control the future of atomic energy. The Atomic Energy Act of 1946 also set up the first National Laboratories. The AEC worked on many nuclear projects. For example, it made uranium fuel cores.

Later, in 1974, the Energy Reorganization Act of 1974 changed things. It split the AEC's duties into two new groups. The Nuclear Regulatory Commission was created to oversee the nuclear power industry. The Energy Research and Development Administration (ERDA) was given the job of managing nuclear weapons and energy development.

Creating the Department of Energy

The 1973 oil crisis showed that the U.S. needed a clear energy plan. In 1977, President Jimmy Carter signed a law called the Department of Energy Organization Act. This law officially created the Department of Energy. The new agency began its work on October 1, 1977. It brought together several older agencies and programs. These included the Federal Energy Administration and the ERDA. James Schlesinger, who had been Secretary of Defense, became the first Secretary of Energy.

President Carter wanted the DOE to help save energy. He also wanted it to find new energy sources. This would reduce the country's reliance on fossil fuels. Energy was a big issue at the time. The oil crisis caused shortages and inflation. The DOE helped President Carter deal with energy challenges. For example, it helped make changes to the Nuclear Regulatory Commission. This improved how nuclear energy and weapons were managed.

Loan Programs and Partnerships

In 2001, the DOE helped sponsor the American Solar Challenge. This was a race for solar-powered cars.

A law passed in 2005, the Energy Policy Act of 2005, allowed the DOE to offer loan guarantees. These guarantees help projects that reduce air pollution or greenhouse gases. They support new or much-improved technologies. A loan guarantee means the DOE promises to help repay a loan if the project meets certain conditions.

In September 2008, the DOE teamed up with other groups. They created the World Institute for Nuclear Security (WINS). This group helps share ideas on how to keep nuclear and radioactive materials safe.

In December 2024, the DOE's Loan Programs Office announced a very large loan. It was a $15 billion loan to Pacific Gas & Electric. This money will help modernize their hydroelectric power system. It will also improve power lines for renewable energy and electric vehicles.

How the Department of Energy is Organized

The Department of Energy changed its organization in 2022. It now has new names for some of its leaders.

The DOE is led by the United States Secretary of Energy. This person is chosen by the President of the United States. The Secretary gets help from the United States Deputy Secretary of Energy. This Deputy Secretary also takes over if the Secretary is away. The department also has three Under Secretaries. They each manage a main part of the DOE's work. There are also seven Assistant Secretaries. They are in charge of different parts of the department.

What the DOE Seal Means

The official seal of the Department of Energy has special meanings. It has a green shield with a gold lightning bolt. On the shield, you can see a sun, an atom, an oil derrick, a windmill, and a dynamo. Above the shield is a white eagle head on a white rope. All of this is on a blue background. The name of the agency is written in gold on a green circle around the edge.

The eagle shows the careful planning needed to meet the country's energy needs. The sun, atom, oil derrick, windmill, and dynamo represent different energy technologies. The rope shows how these technologies work together for our future. The lightning bolt stands for the powerful natural forces that give us energy. It also shows the challenge of using these forces.

The colors in the seal come from nature. They represent where energy comes from and how it supports life. Blue stands for air and water. Green represents mineral resources and the earth. Gold shows the creation of energy from natural forces. These colors mean that the country wants to meet its energy needs while protecting the natural environment.

DOE Research and Development Locations

The Department of Energy runs many national laboratories and technical places. These facilities are used for research and development.

Other important DOE facilities include:

Airstrip:

• Pahute Mesa Airstrip – in Nye County, Nevada, part of Nevada National Security Site

Nuclear Weapons Sites

The DOE, through its NNSA, is in charge of designing, testing, and making all nuclear weapons. The NNSA works with contractors at these government-owned sites:

• Research and Design: Los Alamos National Laboratory and Lawrence Livermore National Laboratory
• Non-Nuclear Parts: Sandia National Laboratories works on the engineering of parts that are not nuclear and puts systems together.
• Key Components: The Kansas City Plant, Savannah River Site, and Y-12 National Security Complex make important parts.
• Testing: The Nevada Test Site is where tests happen.
• Assembly and Taking Apart: Pantex is where weapons are put together and taken apart.

DOE Funding and Spending

In May 2009, President Barack Obama asked for $26.4 billion for the DOE's budget for 2010. This included $2.3 billion for the DOE's Office of Energy Efficiency and Renewable Energy (EERE). This budget aimed to use more renewable energy sources. It also wanted to improve how energy is sent across the country. It planned to invest a lot in hybrid and plug-in hybrid cars. It also focused on smart grid technologies and science research.

As part of a $789 billion economic help package in 2009, Congress gave the DOE an extra $38.3 billion. This was for 2009 and 2010. It added about 75 percent to the DOE's yearly budgets. Most of this money was given as grants and contracts. For 2013, here's how the DOE's main parts spent their money:

In March 2018, Energy Secretary Rick Perry talked about the budget request for 2019. This budget focused on nuclear security. It also made big cuts to programs for energy efficiency and renewable energy. The proposal was a $500 million increase from 2017. It aimed to create a new Office of Cybersecurity, Energy Security, and Emergency Response (CESER). It also planned to strengthen the National Nuclear Security Administration. However, the budget for the Office of Energy Efficiency and Renewable Energy was lowered. It went from $1.3 billion in 2017 to $696 million in the plan. Overall, the department's energy programs were cut by $1.9 billion.

DOE Programs and Projects

Energy Savings Contracts

Energy Savings Performance Contracts (ESPCs) are special agreements. A company designs and builds an energy-saving project. They also get the money needed for it. The government agency then pays the company over time. These payments come from the money saved on utility bills. The company promises that the energy improvements will save money. After the contract ends, all the savings go to the government agency.

Energy Innovation Hubs

Energy Innovation Hubs are places where many different experts work together. They aim to develop new energy science and technology. They take ideas from early research to a point where they are ready for companies to use. The Consortium for Advanced Simulation of Light Water Reactors (CASL) was the first such hub. It started in July 2010. Its goal was to create better computer models for nuclear reactors.

The 2009 DOE budget included $280 million for eight Energy Innovation Hubs. Each hub focuses on a specific energy challenge. Two hubs work on making buildings more energy-efficient. They use smart materials and designs. Another two hubs focus on new ways to store energy. They also work on making fuels directly from sunlight. One more hub develops "smart" materials for the electrical grid. These materials help the grid adapt to changes.

In 2012, the DOE gave $120 million to the Ames Laboratory. This money was to start a new hub called the Critical Materials Institute. This institute works on improving the supply of rare earth elements.

Advanced Research Projects Agency-Energy (ARPA-E)

ARPA-E was officially created in 2007. It is part of the United States Department of Energy. It did not have a budget at first. Its first budget of about $400 million came from an economic stimulus bill in February 2009.
