The conservation of energy implies that an isolated radiating black hole cannot have an emission spectrum that is precisely thermal. Moreover, the no-hair theorem is only approximately applicable. We consider the implications for the black hole information puzzle. b

In the electricity sector, energy conservation through technological and behavioral change is estimated to have a savings potential of 123 million metric tons of carbon per year, which represents 20% of US household direct emissions in the United States. In this article, we investigate the effectiveness of nonprice information strategies to motivate conservation behavior. We introduce environme...

This paper evaluates a series of programs, run by a company called OPOWER, to send Home Energy Report letters to residential utility customers comparing their energy use to that of their neighbors. Using data from randomized natural …eld experiments at 600,000 treatment and control households across the United States, I estimate that the programs reduce energy consumption by 1.1 to 2.8 percent ...

By exploiting the mathematical analogy between the propagation of sound in a nonhomogeneous potential flow and the propagation of a scalar field in curved space-time, various wave "energy" and wave "momentum" conservation laws are established in a systematic manner. In particular, the acoustic energy conservation law due to Blokhintsev appears as the result of the conservation of a mixed covari...

Existing energy conservation interventions provide feedback in the form of graphs and numbers. There is a need for more persuasive and theoretically informed interventions in order to bring about a greater conservation effect. Using the Behaviour Change Wheel (BCW) systematic method of intervention design, we designed a mobile phone game which uses normative feedback as a behaviour change techn...

physiologically thermal comfort condition is a limit of temperature and humidity. ,in which thermal control mechanism of human body is in its least activity . thermal comfort conditions not only have impact on sizes of heating and cooling equipment ,but also affects the thickness of insulation, and .energy, consumption of buildings. it is necessary to define thermal comfort condition for differ...
