Efficiency Law and Legal Definition

Efficiency generally refers to the degree to which operations are done in an economical manner. The Department of Energy (DOE) is the primary federal agency that deals with energy effiiciency and aims to develop energy efficient technologies for buildings, homes, transportation, power systems and industry. The mission of the DOE's Office of Energy Efficiency and Renewable Energy (EERE) is to strengthen America's energy security, environmental quality, and economic vitality in public-private partnerships that: enhance energy efficiency and productivity; bring clean, reliable and affordable energy technologies to the marketplace; and enhance energy choices and quality of life.

EERE leads the Federal government’s research, development, and deployment efforts in energy efficiency. EERE's role is to invest in high-risk, high-value research and development that is critical to the nation's energy future and would not be sufficiently conducted by the private sector acting on its own. Program activities are conducted in partnership with the private sector, state and local government, DOE national laboratories, and universities. EERE also works with others to develop programs and policies to promote advanced clean energy technologies and practices.
