Der Ölpreis wird von zahlreichen Faktoren beeinflusst. Die OPEC spielt bei der Preisbildung derzeit nur eine geringe Rolle. Ein Peak Oil wird die Ölpreise stark beeinflussen und zahlreiche Ausweichdynamiken in Gang setzen, die in ihrer Struktur und Quantität bisher jedoch meist unverstanden sind. Ein ökonomischer Ansatz zu deren Bewertung greift aufgrund vorliegender nicht-ökonomischer Hemmnisse zu kurz. Eine Folge von Rohstoffverknappungen ist eine steigende Energieunsicherheit auf globaler Ebene. Daher ist ein grundsätzlicher Umbau der heutigen Versorgungsstrukturen geboten, um in Zukunft besser gegen strukturelle Unsicherheiten gerüstet zu sein.
The analysis of different global energy scenarios in part I of the report confirms that the exploitation of energy efficiency potentials and the use of renewable energies play a key role in reaching global CO2 reduction targets. An assessment on the basis of a broad literature research in part II shows that the technical potentials of renewable energy technologies are a multiple of today's global final energy consumption. The analysis of cost estimates for renewable electricity generation technologies and even long term cost projections across the key studies in part III demonstrates that assumptions are in reasonable agreement. In part IV it is shown that by implementing technical potentials for energy efficiency improvements in demand and supply sectors by 2050 can be limited to 48% of primary energy supply in IEA's "Energy Technology Perspectives" baseline scenario. It was found that a large potential for cost-effective measures exists, equivalent to around 55-60% of energy savings of all included efficiency measures (part V). The results of the analysis on behavioural changes in part VI show that behavioural dimensions are not sufficiently included in energy scenarios. Accordingly major research challenges are revealed.
