The Center of Excellence in Energy Efficiency – EXCEN – is composed of a group of professionals and academics interested in the enhancement of the energy usage, from its basics transformations to its final end use. The EXCEN is a nonprofit organization that is located at the Itajubá Federal University, Itajubá Campus, Minas Gerais State, Brazil. Its main researchers supervise several academic and industrial projects, aiming at the maximum and reasonable exploitation of the natural resources under the most rigid environmental constraints. Cutting-edge technologies of power generation, management and storage, have been developed, along with losses minimization in the energy transportation and final use, covering two main streams: the proposal of new technologies and the encouraging the adoption of energy efficient consumption patterns. Some of the current projects include development of advanced, internet based, educational material on energy efficiency for the industry in graduate and post-graduate levels, development energy efficiency opportunities identification, development of technic and economic models for nationwide energy efficiency measures evaluation.
