Erneuerbare Energien: Status und Potentiale


  • Antonio Pflüger


Under today's conditions, global energy demand would double until 2050 and CO2 emissions could be expected to increase even more (by 137%). This would be related to an increasing dependence of OECD member countries on energy imports, and also to a further aggravation of the global greenhouse effect, which is responsible for heating up the atmosphere. In combination with other technologies, renewable energies are going to play an important role in meeting these problems. Further preconditions are a simultaneous improvement in energy efficiency, further advances in cost reduction of renewable energies and a broad implementation of renewable energies in further countries. If such a reorganization is to take place, then industry, research institutions and policy are conjointly asked to meet the related challenges. Unter heutigen Rahmenbedingungen muss davon ausgegangen werden, dass der globale Primärenergieverbrauch sich bis 2050 mehr als verdoppeln wird und die energiebedingten CO2-Emissionen sogar um 137% steigen. Die Abhängigkeit der OECD-Staaten von Energieimporten würde weiter wachsen und der Treibhausgaseffekt, der für die Erwärmung der Erdatmosphäre verantwortlich gemacht wird, würde weiter zunehmen. Erneuerbare Energien können und müssen im Mix mit anderen Technologien zur Lösung dieser Probleme eine Rolle spielen. Weitere wichtige Voraussetzungen sind eine gleichzeitige Verbesserung der Energieeffizienz, weitere Fortschritte bei der Reduzierung der Kosten der neuen erneuerbaren Energien und ein breiterer Einsatz in mehr Ländern als bisher. Die damit verbundenen Umstrukturierungen und die Integration der neuen erneuerbaren Energien in die bestehende Energieversorgung ist mit Herausforderungen verbunden, die - wenn ein Umbau stattfinden soll - Wirtschaft, Forschung und Politik gemeinsam angehen müssen.
