The Department of Energy has one of the richest and most diverse histories in the Federal Government. Although only in existence since 1977, the Department traces its lineage to the Manhattan Project effort to develop the atomic bomb during World War II, and to the various energy-related programs that previously had been dispersed throughout various Federal agencies.

Science and Innovation
As a science agency, the Energy Department plays an important role in the innovation economy. The Department catalyzes the transformative growth of basic and applied scientific research, the discovery and development of new clean energy technologies and prioritizes scientific innovation as a cornerstone of US economic prosperity.
Through initiatives like the Loan Programs Office and the Advanced Research Projects Agency-Energy (ARPA-E), the Department funds cutting-edge research and the deployment of innovative clean energy technologies. The Department also encourages collaboration and cooperation between industry, academia and government to create a vibrant scientific ecosystem.
In addition, the Energy Department’s 17 National Laboratories are a system of intellectual assets unique among world scientific institutions and serve as regional engines of economic growth for states and communities across the country.
A clean energy revolution is taking place across America, underscored by the steady expansion of the U.S. renewable energy sector.
The clean energy industry generates hundreds of billions in economic activity, and is expected to continue to grow rapidly in the coming years. There is tremendous economic opportunity for the countries that invent, manufacture and export clean energy technologies.
Responsible development of all of America’s rich energy resources — including solar, wind, water, geothermal, bioenergy & nuclear — will help ensure America’s continued leadership in clean energy. Moving forward, the Energy Department will continue to drive strategic investments in the transition to a cleaner, domestic and more secure energy future.
Addressing the effects of climate change is a top priority of the Energy Department. As global temperatures rise, wildfires, drought, and high electricity demand put stress on the nation’s energy infrastructure. And severe weather — the leading cause of power outages and fuel supply disruption in the United States — is projected to worsen, with eight of the 10 most destructive hurricanes of all time having happened in the last 10 years.
To fight climate change, the Energy Department supports research and innovation that makes fossil energy technologies cleaner and less harmful to the people and the environment. We’re taking responsible steps to cut carbon pollution, develop domestic renewable energy production and win the global race for clean energy innovation. We’re also working to dramatically increase the efficiency of appliances, homes, businesses and vehicles .
Primary energy sources take many forms, including nuclear energy, fossil energy — like oil, coal and natural gas — and renewable sources like wind, solar, geothermal and hydropower. These primary sources are converted to electricity, a secondary energy source, which flows through power lines and other transmission infrastructure to your home and business.
