Energy consumption

Tables  89, 91 illustrate the direct energy consumption of the Group, in other words that which involves the use of primary sources for the functioning of the production system, including the consumption for generation of electricity and heat and the fuels used for the vehicle fleet. 

Table No. 90 indicates the indirect energy consumption, in other words the electricity used in the Group, including the losses which take place on the distribution networks, attributable to the transformation and transport phases, fraud and erroneous metering.
