Methodology to decrease the energy demands in wine production using cold pre-fermentation

In this study, it can be seen how a simple installation based on wind energy and photovoltaic solar energy can reduce the energy consumption needed from the electric network by 30%. Together with renewable energy based production, the different performances of energy efficiency and a correct active energy management through the measuring and verification of the installation, reductions of over 50% in the energy demand of the network can be achieved.
