History


Formation and consolidation

In 1942, during
World War II World War II or the Second World War (1 September 1939 – 2 September 1945) was a World war, global conflict between two coalitions: the Allies of World War II, Allies and the Axis powers. World War II by country, Nearly all of the wo ...
, the United States started the Manhattan Project to develop the atomic bomb under the U.S. Army Corps of Engineers. After the war, in 1946, the Atomic Energy Commission (AEC) was created to control the future of the project. The Atomic Energy Act of 1946 also created the framework for the first National Laboratories. Among other nuclear projects, the AEC produced fabricated uranium fuel cores at locations such as Fernald Feed Materials Production Center in

The Energy Reorganization Act of 1974 split the responsibilities of the AEC into the new Nuclear Regulatory Commission, which was charged with regulating the nuclear power industry, and the Energy Research and Development Administration, which was assigned to manage the nuclear weapon, naval reactor, and energy development programs. The

The new agency, which began operations on October 1, 1977, consolidated the Federal Energy Administration, the Energy Research and Development Administration, the Federal Power Commission, and programs of various other agencies. Former Secretary of Defense James Schlesinger, who served under Presidents Nixon and Ford during the

, was appointed as the first secretary. President Carter proposed the Department of Energy with the goal of promoting energy conservation and energy independence, and developing alternative sources of energy to reduce the use of fossil fuels. With international energy's future uncertain for America, Carter acted quickly to have the department come into action the first year of his presidency. This was an extremely important issue of the time as the oil crisis was causing shortages and inflation. With the Three Mile Island accident, Carter was able to intervene with the help of the department. Through the DOE, Carter was able to make changes within the Nuclear Regulatory Commission, including improving management and procedures, since nuclear energy and weapons are responsibilities of the department.


Weapon plans stolen

In December 1999, the FBI was investigating how China obtained plans for a specific nuclear device. Wen Ho Lee was accused of stealing nuclear secrets from Los Alamos National Laboratory for the

. Federal officials, including then-Energy Secretary Bill Richardson, publicly named Lee as a suspect before he was charged with a crime. The U.S. Congress held hearings to investigate the Department of Energy's handling of his case. Republican senators thought that an independent agency should be in charge of

and security issues, rather than the DOE. All but one of the 59 charges against Lee were eventually dropped because the investigation proved the plans the Chinese obtained could not have come from Lee. Lee filed suit and won a $1.6 million settlement against the federal government and news agencies. The episode eventually led to the creation of the National Nuclear Security Administration, a semi-autonomous agency within the department.

authorizes the DOE to issue loan guarantees to eligible projects that "avoid, reduce, or sequester air pollutants or anthropogenic emissions of greenhouse gases" and "employ new or significantly improved technologies as compared to technologies in service in the United States at the time the guarantee is issued". In loan guarantees, a conditional commitment requires to meet an equity commitment, as well as other conditions, before the loan guarantee is completed. In September 2008, the DOE, the Nuclear Threat Initiative (NTI), the Institute of Nuclear Materials Management (INMM), and the International Atomic Energy Agency (IAEA) partnered to develop and launch the World Institute for Nuclear Security (WINS), an international

designed to provide a forum to share best practices in strengthening the security and safety of nuclear and radioactive materials and facilities. In December 2024, the Loan Programs Office announced it would extend the largest loan ever sanctioned – a $15 billion (US) low-interest loan to support the modernization of Pacific Gas & Electric’s hydroelectric power structure, enhance transmission lines critical for renewable energy integration, data center operations, and the growing fleet of electric vehicles. Initially requested as a $30 billion (US) loan, the amount was reduced due to concerns over the company’s repayment capacity.

Budget

On May 7, 2009 President Barack Obama unveiled a $26.4 billion budget request for DOE for fiscal year (FY) 2010, including $2.3 billion for the DOE Office of Energy Efficiency and Renewable Energy (EERE). That budget aimed to substantially expand the use of

technologies, and scientific research and innovation. As part of the $789 billion economic stimulus package in the American Recovery and Reinvestment Act of 2009, Congress provided Energy with an additional $38.3 billion for fiscal years 2009 and 2010, adding about 75 percent to Energy's annual budgets. Most of the stimulus spending was in the form of grants and contracts. For fiscal year 2013, each of the operating units of the Department of Energy operated with the following budgets: In March 2018, Energy Secretary Rick Perry testified to a Senate panel about the Trump administration's DOE budget request for fiscal year 2019. The budget request prioritized nuclear security while making large cuts to energy efficiency and renewable energy programs. The proposal was a $500 million increase in funds over fiscal year 2017. It "promotes innovations like a new Office of Cybersecurity, Energy Security, and Emergency Response (CESER) and gains for the Office of Fossil Energy. Investments would be made to strengthen the National Nuclear Security Administration and modernize the nuclear force, as well as in weapons activities and advanced computing." However, the budget for the Office of Energy Efficiency and Renewable Energy would be lowered to $696 million under the plan, down from $1.3 billion in fiscal year 2017. Overall, the department's energy and related programs would be cut by $1.9 billion.


Programs and contracts


Energy Savings Performance Contract

Energy Savings Performance Contracts (ESPCs) are contracts under which a contractor designs, constructs, and obtains the necessary financing for an energy savings project, and the federal agency makes payments over time to the contractor from the savings in the agency's utility bills. The contractor guarantees the energy improvements will generate savings, and after the contract ends, all continuing cost savings accrue to the federal agency.


Energy Innovation Hubs

Energy Innovation Hubs are multi-disciplinary, meant to advance highly promising areas of energy science and technology from their early stages of research to the point that the risk level will be low enough for industry to commercialize the technologies. The Consortium for Advanced Simulation of Light Water Reactors (CASL) was the first DOE Energy Innovation Hub established in July 2010, for the purpose of providing advanced modeling and simulation (M&S) solutions for commercial nuclear reactors. The 2009 DOE budget includes $280 million to fund eight Energy Innovation Hubs, each of which is focused on a particular energy challenge. Two of the eight hubs are included in the EERE budget and will focus on integrating smart materials, designs, and systems into buildings to better conserve energy and on designing and discovering new concepts and materials needed to convert solar energy into electricity. Another two hubs, included in the DOE Office of Science budget, were created to tackle the challenges of devising advanced methods of energy storage and creating fuels directly from sunlight without the use of plants or microbes. Yet another hub was made to develop "smart" materials to allow the electrical grid to adapt and respond to changing conditions. In 2012, the DOE awarded $120 million to the Ames Laboratory to start a new EIH, the Critical Materials Institute, which will focus on improving the supply of rare earth elements.


Advanced Research Projects Agency-Energy

ARPA-E was officially created by the America COMPETES Act , authored by Congressman Bart Gordon, within the United States Department of Energy (DOE) in 2007, though without a budget. The initial budget of about $400 million was a part of the economic stimulus bill of February 2009.
