Role and Potential of Renewable Energy and Energy Efficiency for Global Energy Supply

摘要: The analysis of different global energy scenarios in part I the report confirms that exploitation efficiency potentials and use renewable energies play a key role reaching CO2 reduction targets. An assessment on basis broad literature research II shows technical technologies are multiple today's final consumption. cost estimates for electricity generation even long term projections across studies III demonstrates assumptions reasonable agreement. In IV it is shown by implementing improvements demand supply sectors 2050 can be limited to 48% primary IEA's "Energy Technology Perspectives" baseline scenario. It was found large potential cost-effective measures exists, equivalent around 55-60% savings all included (part V). results behavioural changes VI show dimensions not sufficiently scenarios. Accordingly major challenges revealed.
