Before revision:  Are analyzed the physical characteristics of the material elements used to represent value and how the energy matrix of an economy can play an important role in the sustained growth, through the adoption of a new monetary standard, based on the energy supply capacity .
After revision:  Are analyzed the physical characteristics of the gold-standard being considered as outdated, it provides valuable signs concerning the development of novel monetary standards, better adjusted to the current macroeconomic environment. By using a point of view of classical physics, the intent of this work is doing a review of the concept of monetary standard and show that the energy matrix of an economy can play an important role in the sustained growth, through the adoption of a new monetary standard, based on the energy supply capacity .
