FERREIRA-DA SILVA, Osvaldo André Paulo et al. Use of Renewable Energy in Agricultural Processes to Produce Food. Rev Cie Téc Agr [online]. 2022, vol.31, n.1  Epub Nov 12, 2021. ISSN 2071-0054.

This work deals with the problem of food insecurity in the central region of Cuba, in a context characterized by the depletion of conventional energy sources and the negative effects of climate change. In Los Milian farm, Ciego de Ávila Province, the application of a closed cycle production process is foreseen for the production of food with the rational use of water and energy. It is conceived to use the surpluses of the biogas production process and to utilize dry matter as bio fertilizer. A system of treatment to reduce the pollutant load of the effluents, a domestic supply system coupled to a photovoltaic solar pump and an irrigation system compatible with the hours of least consumption of electricity are proposed. The results generate a positive social and environmental impact for Ciego de Ávila Province.

Keywords : Water; Biomass; Solar Arrangement; Irrigation.
