Mit der NEED-Plattform werden die Prozesse eines Datenökosystems beschleunigt. Automatisiert werden heterogene energiebezogene Datenquellen zusammengeführt und mittels Ontologien konsistent über die verschiedenen Sektoren sowie zeitliche und räumliche Ebenen verknüpft. In diesem Zusammenhang sollen bestehenden Datenplattformen nicht ersetzt, sondern vielmehr als Quelle in das Ökosystem integriert werden. Neben konventionellen Datenquellen der verschiedenen Planungsebenen sollen dabei auch Möglichkeiten erforscht werden, um Lücken mit synthetischen Daten zu schließen. Die NEED-Plattform ist ein robustes, pflegeleichtes und flexibles Werkzeug zur Planung von Energiemaßnahmen auf verschiedenen räumlichen Ebenen, ohne das Gesamtbild aus dem Blick zu verlieren. Werkzeuge und Modelle der Partner sollen über semantische Anfragen auf die erforderlichen Daten zugreifen, um die jeweiligen (Planungs-)Aufgaben durchzuführen. Der NEED Ansatz für eine transparente Bereitstellung aktueller Daten wird an Anwendungsbeispielen evaluiert. Teilvorhaben RWTH: Energieszenarien für räumliche Ontologien und Datensynthetisierung: Ziel ist die Analyse und Weiterentwicklung von Ontologien, die Ermittlung von synthetischen Daten und die Erstellung von Energieszenarien mit räumlich und topologisch flexiblen Systemgrenzen.
The objective of this study is to present an alternative and more realistic view of the chances of the future uses of renewable energies in the global energy supply. The scenarios in this study are based on the analysis of the development and market penetration of renewable energy technologies in different regions in the last few decades. The scenarios address the question of how fast renewable technologies might be implemented on a worldwide scale and project the costs this would incur. Many factors, such as technology costs and costreduction ratios, investments and varying economic conditions in the worlds regions, available potentials, and characteristics of growth have been incorporated in order to fulfil this task. Off course the scenarios describe two possible developments among other possibilities, but they represent realistic possibilities that give reason for optimism. The results of both scenarios show that - until 2030 - renewable capacities can be extended by a far greater amount and that it is much cheaper than most scientist and people actually think. The scenarios do explicitly not describe a maximum possible development from the technological perspective but show that much can be achieved with even moderate investments. The scenarios do not pay attention to the further development of Hydropower, except for incorporating the extensions that are planned actually. This is not done to express our disbelief in the existence of additional potentials or to ignore Hydropower, but due to the fact that reliable data about sustainable Hydropower potentials were not available. Consequently, the figures in this study show how much can be achieved, even if Hydropower remains on today's levels more or less. Higher investments into single technologies, e.g. Hydropower or Biomass, or in general than assumed in the REO 2030 scenarios will result in higher generating capacities by 2030. On the global scale scenario results for 2030 show a 29 percent renewable supply of the heat and electricity (final energy demand) in the High Variant . According to the Low Variant over 17 percent of the final electricity and heat demand can be covered by renewable energy technologies. Presuming strong political support and a barrier-free market entrance, the dominating stimulus for extending the generation capacities of renewable technologies is the amount of money invested. Within the REO scenarios we assume a growing 'willingness to pay' for clean, secure and sustainable energy supply starting with a low amount in 2010. This willingness to pay gets expressed as a target level for annual investments per inhabitant (capita) that will be reached by the year 2030. The targeted amounts differ for the various regions of the world. In global average 124 € 2006 are spent in 2030 per capita in the 'High Variant'. In the 'Low Variant' the target for 2030 is half that amount (62 € 2006 per capita and year). ...
