Law of physics and chemistry This article is about the law of conservation of energy in physics. For sustainable energy resources, see Energy conservation. Part of a series on Continuum mechanics J = − D d φ d x {\displaystyle J=-D{\frac {d\varphi }{dx}}} Fick's laws of diffusion ...

Now consider the first law without the heating term: dU = −P dV. The pressure P can be viewed as a force (and in fact has units of force per unit area) while dV is the displacement (with units of distance times area). We may say, with respect to this work term, that a pressure difference forces a transfer of volume, and that the product of ...
The first law of thermodynamics is a version of the law of conservation of energy, adapted for thermodynamic processes. In general, the conservation law states that the total energy of an isolated system is constant; energy can be transformed from one form to another, but can be neither created nor destroyed.
Energy conservation is the effort to reduce wasteful energy consumption by using fewer energy services. This can be done by using energy more effectively (using less and better sources of energy for continuous service) or changing one's behavior to use less and better source of service (for example, by driving vehicles which consume renewable ...
Low-cost energy feedback displays, such as the Energy Detective or Wattvision, [4] [5] have become available. A study of a similar device deployed in 500 homes in Ontario, Canada, by Hydro One showed an average 6.5% drop in total electricity use when compared with a similarly sized control group. [ 6 ]

The Energy Policy and Conservation Act of 1975 (EPCA) (Pub. L. 94–163, 89 Stat. 871, enacted December 22, 1975) is a United States Act of Congress that responded to the 1973 oil crisis by creating a comprehensive approach to federal energy policy.
