Among other things, these calculations are needed to monitor and control political support schemes, i.e., to assess their impact and to avoid "flying blind". The calculated savings depend on a large number of assumptions and caution should be exercised when comparing savings. It helps to have a transparent calculation methodology and an awareness of the possible assumptions which have been made. In the series ENERGY EXPLAINED by the Fraunhofer Institute for Systems and Innovation Research ISI, scientists investigate complex issues from the field of energy research and offer a clear and concise introduction to the respective topics.enpaper
