Energy conservation is the effort to reduce wasteful energy consumption by using fewer energy services. This can be done by using energy more effectively...

performance of work and in the form of heat and light. Energy is a conserved quantity—the law of conservation of energy states that energy can be converted...

law of conservation of mass or principle of mass conservation states that for any system closed to all transfers of matter and energy, the mass of the...

sciences, mechanical energy is the sum of potential energy and kinetic energy. The principle of conservation of mechanical energy states that if an isolated...

of the conservation of energy, having previously swallowed up that of the conservation of heat, now proceeded to swallow that of the conservation of mass—and...

Exact conservation laws include conservation of mass-energy, conservation of linear momentum, conservation of angular momentum, and conservation of electric...

The Energy Policy and Conservation Act of 1975 (EPCA) (Pub. L.Tooltip Public Law (United States) 94–163, 89 Stat. 871, enacted December 22, 1975) is a...
