Terna does not use raw materials, but electrical equipment and other components that it combines for use in the transmission service. The table – which is produced in this report for the first time and is therefore to be considered as still approximate – shows the main raw materials contained in the supplies used by Terna. The weight calculation is based on the quantity used, the average or typical weight of the single elements, and the share of raw materials contained. In some cases, the elements consist of a single raw material (for example, insulators consist 100% of glass or ceramic, terminals 100% of alluminium), while in other cases the main material has been estimated (for example, copper constitutes 60% of the weight of an ATR transformer). At the present time, information on the use of recycled material by the suppliers of the materials and equipment used is not available.

The main material consumed in office work is paper.

Paper consumption regards the quantity purchased. The recording boundary is more inclusive than in 2008 and now includes all 8 operating areas with their main offices, with the exception of the head office, in Rome. The current figure is therefore lower than Terna’s total consumption.

Water is not part of the production cycle  of electricity transmission and dispatching. The water used for cleaning and personal hygiene in Terna’s offices normally comes from connections to waterworks. The increase in consumption in 2009 reflects mainly the improvement in recording procedures begun in 2008, but also a leak in a pipe in one of the Company’s regional offices.
