| Summary/Abstract |
The Energy [R]evolution 2008 scenario is an update of the Energy [R]evolution scenario published in 2007. It takes up recent trends in global socio-economic developments, and analyses to which extent they affect chances for achieving global climate protection targets. The main target is to reduce global CO2 emissions to 10 Gt per year in 2050, thus limiting global average temperature increase to 2 °C and preventing dangerous anthropogenic interference with the climate system. A review of sector and region specific energy efficiency measures resulted in the specification of a global energy demand scenario incorporating strong energy efficiency measures. The corresponding energy supply scenario has been developed in an iterative process in close cooperation with stakeholders and regional counterparts from academia, NGOs and the renewable energy industry. The Energy [R]evolution scenario shows that renewable energy can provide more than half of the world's energy needs by 2050. Developing countries can virtually stabilise their CO2 emissions, whilst at the same time increasing energy consumption through economic growth. OECD countries will be able to reduce their emissions by up to 80%.

| Summary/Abstract |
The transformation of the energy supply in Germany (the "Energiewende") as described in the German Federal government's 'Energy Concept' ( Energiekonzept, 2010) is based on a political consensus about long-term targets for energy efficiency and renewable energies. The aim of this article is to present a consistent scenario for this transformation process reflecting the long-term implementation of renewable energies and the possible future structure of the German energy system as a whole. Structural and economic effects of this development are derived and discussed. It summarizes results of scenario analyses done by the department of Systems Analysis and Technology Assessment of the German Aerospace Center as part of a three-year research project for the German Federal Ministry for the Environment. The underlying study provides a detailed data base reflecting a long-term roadmap for the energy system transformation in Germany. The scenarios show that the policy targets are consistent and can be achieved, if appropriate policy measures are to be implemented. The economic analysis shows the amount of investments and the strong market dynamics required for new generation technologies but also the huge economic benefits that can result from this development path in terms of fuel cost savings and lower fuel imports.

| Summary/Abstract |
The huge solar resources in the MENA countries (Middle East and North Africa), significant improvements in concentrating solar power (CSP) technology and in power transmission technologies, and the urgent need to remove carbon emissions from the European (EU) energy system lead to an increased interest in an EU-MENA electricity grid interconnection. As contribution to the current discussions about DESERTEC, MedGrid and other initiatives this article describes the approach and results of an analysis of possible solar electricity import corridors from MENA to Europe including Turkey. The study is based on solar energy potentials of the MENA countries identified by remote sensing, reviewed performance and cost data of generation and transmission technologies, and geographic data and information systems (GIS) for the spatial analysis. CSP plants combined with high temperature heat storage and high voltage direct current (HVDC) overhead lines and sea cables represent the key technologies for implementing this promising option for renewable energy import/export. The total technical solar power generation potential from remote sensing analysis in the seven MENA countries considered was calculated to about 538,000 TWh/yr. This huge potential implies that less than 0.2% of the land suitable for CSP plants would be enough to supply 15% of the electricity demand expected in Europe in the year 2050. A GIS analysis of potential future HVDC corridors led to the description and characterization of 33 possible import routes to main European centers of demand.
