With the aid of the graphs shown above it is possible to clearly highlight various information items. » How great are the individual input and output streams (e.g. emissions, energy demand? » How great are the individual input and output streams in comparison with others? » Where are the input and output streams too great? » Which input and output streams are the principal energy consumers?
The aim of these graphs is to present the result in a way which can be readily understood by all persons concerned. It often happens that potentials become visible only when they have been presented in graphic form. It is important that decision-makers should be informed as efficiently as possible. They need the material to be demonstrated as vividly as possible, since very often they do not have sufficient time to study the subject in greater depth.
