Which facility in New Mexico is known for its development in energy research?

Los Alamos is recognized for its significant contributions to energy research, primarily due to its historical role in the development of nuclear energy and weapons during the Manhattan Project. Established in 1943, Los Alamos National Laboratory has since evolved into a center for scientific research, focusing on nuclear physics, renewable energy technologies, and energy efficiency. The lab conducts various experiments and research initiatives aimed at addressing energy challenges, including advancing technologies for cleaner and more sustainable energy solutions.

The other options do not have the same focus on energy research. Sandestin National Labs is not a recognized facility, and while Cannon Air Force Base and Walker Air Force Base have their specific military functions, they are not primarily associated with energy research in the same way that Los Alamos is. This emphasis on nuclear and energy research makes Los Alamos the correct answer in this context.
