The residues from agricultural and agroindustrial activities are not adequately valorised and at best they are destined for animal consumption or else they are inadequately disposed of. The objective of the present work was to present alternatives to valorise, estimate, report and highlight the energy potential of second-generation bioethanol production using lignocellulosic biomass from the most important crops in Peru. The biomass considered in this studio was from the harvest and processing of sugarcane, rice, banana, yellow corn, oil palm and asparagus. It was determined that the annual lignocellulosic biomass availability is a mean of ~22 million tons, from which, 33.03% correspond to banana waste, 28.56% correspond to sugarcane waste. The potential of bioethanol production and energy generation was obtained using a theory conversion of cellulose, hemicellulose of each biomass. It was calculated 3.51 million tons of bioethanol/year, which total energy corresponds to 2.16 million toe/year with an electric energy potential of 8.81 GWh/year. This quantity could be enough to supply 9.11% and the total national energy demand and 0.02% of the electric energy demand, besides it could help reduce in about 19.86% the CO2 emissions.
