Because of the fickle nature renewable sources energy production, professionals in this sector have developed hybrid systems (HRES) that offer a constant and stable load supply. This research intends to build off-grid (HES) Malang, Indonesia, uses solar generator, wind turbine, biogas power public buildings. The HOMER program was used construct model. Following computations, multiple system mod...

This paper reviews the fundamentals of Exergy Cost Theory, an energy cost accounting methodology to evaluate physical costs products systems and their associated waste. Besides, a mathematical computationally approach is presented, which will allow practitioner carry out studies on production regardless structural complexity. The exergy theory was proposed in 1986 by Valero et al. “General savi...
