Renewable energies (RNE) and energy efficiency (EE) are considered as twin pillars in the energy strategic battle to decrease fossil energy consumption.The combined potential of energy efficiency and renewable energy to reshape energy future is substantial. The energy consumption profile of an industry process or facility is considered to be an energy footprint and a main axis in its life. The aim of this paper is to highlight to the existing energy profile of a facility or industry process and to elaborate different steps to reduce it by exposing an innovative algorithm (methodology), contributing between EE and RNE, to achieve a low energy profile in residential, commercial and industrial sectors.
