Abstract
In this paper, a technical-economic-environmental analysis was carried out to establish the feasibility of implementing different types of hybrid energy systems. Four hybrid systems (solar-wind) were designed: with battery, with gas generator, grid-connected and with a diesel generator. These systems were analyzed using the HOMER software, which allows the calculation of pollutant gas emissions and simulates and optimizes energy consumption based on energy demand and energy resources. For the financial analysis, the net present value (NPV), the internal rate of return (IRR) and the payback period (PBP) were used, which were calculated using Microsoft Excel. The four systems were designed for the energy demand of the luminaires of the academic building of the Universidad del Magdalena. The results obtained show that the first three systems are profitable for their implementation taking into account the capacity of power generation, gas emissions and the PBP.Keywords: Hybrid Energy System, Environmental Analysis, Financial AnalysisJEL Classifications: Q42, Q51, G00DOI: https://doi.org/10.32479/ijeep.8473
Highlights
Renewable energies have been partially replacing fossil fuels and nuclear energy in four different markets: electricity generation, thermal applications, transportation fuels and energy services off-grid (Rocas, 2018; Robles et al, 2017). Such is the case of photovoltaic solar energy (PV) and wind energy (Tizgui et al, 2018), which represented a considerable increase in recent years, especially in 2017, where more PV capacity was added than any other type of energy in all the world (Frankfurt School, 2018)
Worldwide there is an expansion in the market and this is largely due to the growing competitiveness of renewable energy combined with the growing demand for electricity in developing countries, as well as the advantages offered by this type of energy to mitigate pollution (Solar Power Europe, 2017)
Energy Potential we present a description of the wind, solar and ambient temperature resources that exist in the study area of this work. This information was obtained thanks to the simulation tool hybrid optimization of multiple energy resources (HOMER) (HOMER Energy, 2019), which is connected to the database of National Aeronautics and Space Administration (NASA)
Summary

Brazil advanced to occupy the tenth global place in aggregate capacity in 2017, the country represents only about 1% of global additions (Bellini, 2018)
