What happens is that, in order to achieve the same level of utility, the individual can consume less energy. In an energy context, let's consider what happens when an individual buys a more efficient car-the same can be said for light bulbs, home insulation, and so forth. Ironically, economists call it the Piggy Principle. The key point regarding this theory is that one of the theory's unproven principles - the axioms - predicts that, for each individual, utility always increases as the consumption of any commodity increases. This is exactly the same theory studied in Basic Economics courses.ДЄccording to Consumer theory, individuals choose the level of commodity consumption which, considering their own income and the price requested, maximizes their own Utility. In this regard, the economic literature is still pegged to the Consumer theory developed by economists such as Walras, Pareto and other Marginalists between the late 19th and the early 20th century. On the other side, we should also remember that Jevons paradox applies exclusively to the production sphere: the world of the so-called вЂconsumerвЂ™ behaves very differently. Considering that, the myth of entrepreneurs reluctant to adopt available methods to increase efficiency should be abandoned: in fact, investment in energy efficiency should be considered business as usual. Resource consumption has continued to increase in the long term, in spite of acknowledged gains in efficiency and productivity. We should also remember that industrial development comes from a long history of efficiency increases in the use of productive resources, those being either energy or labor or credit or raw materials. With respect to production, the proposed solutions (increases in power plants efficiency, changes to EFF1 electric motors, inverters applied to pumps and motors, improvements in the efficiency of compressed air systems, etc.) will inevitably get caught in the trap of Jevons paradox.

First of all, we should distinguish between two different economic spheres: production and consumption.
