Energy, exergy and exergoenvironmental analyses of a sugarcane bagasse power cogeneration system

One of the strategies to reduce the environmental impacts associated with electricity is to employ renewable resources such as biomass or even waste. However, the evaluation of the sustainability of a power plant depends on the development of several analyses, which should encompass thermodynamic a...
