National Laboratories are research facilities funded by the government, primarily in the United States. They focus on scientific research and development in various fields, including energy, environmental science, and national security. These labs often collaborate with universities and private industries to advance technology and innovation. Each National Laboratory has specific areas of expertise, such as Los Alamos National Laboratory, known for nuclear research, and Oak Ridge National Laboratory, which specializes in energy efficiency. Their work contributes to public policy, scientific knowledge, and technological advancements that benefit society as a whole.
