Energetic Saving
Energetic Saving
Energetic saving you must be diverged proper techniques for to reduce the consumptions of necessary energy to the carrying out of the various human activities.
The saving can be gotten both modifying the trials so that there is less wastes both using technologies able to turn the energy from a form to the other into more efficient way or also through the auto production.
One of the most common examples are given by the substitution of the incandescence light bulbs with those fluorescent that send forth a quantity of energy bright different times superior to the first to parity of consumed energy.
An energetic saving can also be had to level of production of electric energy using systems of fit cogenerazione to improve the outputs of the various trials, that consist in fit technologies to get, simultaneously for instance, electric energy and heat; or they are used in "fallen" the same energetic flows to increasing entropies for diversified uses or, finally, to effect forms of energetic recovery to.
Or exploiting the energy dispersed by the motion of the human beings or the automobiles, as you has already been done in Holland, for instance with sensitive floors to the pressure that produce electric energy, sets in the staircases of the subways more frequented of the world.
The effects of these politics must be always considered in relationship to the Paradox of Jevons.
To use electric energy to produce heat represent a waste from the thermodynamic point of view because a noble energy turns him into heat that is an energy of second kind.
In base to the first two principles of the thermodynamics, the energy mechanics-electric you can entirely be convert in heat, while the heat can be reconverted only partly in energy.
A second motive for waste derives from the fact that a lot of forms of energy (thermoelettric, nuclear, solar) produce heat to produce energy, that is again used for the electric heating: to every passage there is an increase of entropy and a loss of thermodynamic output.
