However, models simplify the dynamics involved in implementing climate policy and the results depend on critical model assumptions such as global participation in climate policy and full availability of current and newly evolving technologies. The design of a low stabilization policy regime in the real world depends on factors that can only be partly covered by models. In this context, the paper reflects on limits of the integrated assessment models used to explore climate policy and addresses the issues of (i) how global participation might be achieved, (ii) which kind of options are available to induce deep GHG reductions inside and outside the energy sector, and (iii) which risks and which co-benefits of mitigation options are not assessed by the models.}, language = {en} } @article{EdenhoferFlachslandLuderer, author = {Edenhofer, Ottmar and Flachsland, Christian and Luderer, Gunnar}, title = {Eckpunkte einer globalen Klimaschutzpolitik}, series = {Kirche und Gesellschaft}, journal = {Kirche und Gesellschaft}, number = {355}, language = {de} } @article{UeckerdtHirthLudereretal., author = {Ueckerdt, Falko and Hirth, Lion and Luderer, Gunnar and Edenhofer, Ottmar}, title = {System LCOE: What are the costs of variable renewables?}, series = {Energy}, volume = {63}, journal = {Energy}, publisher = {Elsevier Ltd}, issn = {0360-5442}, doi = {10.1016/j.energy.2013.10.072}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:b1570-opus4-22942}, pages = {61 -- 75}, abstract = {Levelized costs of electricity (LCOE) are a common metric for comparing power generating technologies. However, there is criticism particularly towards evaluating variable renewables like wind and solar PV power based on LCOE because it ignores variability and integration costs. We propose a new metric System LCOE that accounts for integration and generation costs. For this purpose we develop a new mathematical definition of integration costs that directly relates to economic theory. As a result System LCOE allow the economic comparison of generating technologies and deriving optimal quantities in particular for VRE. To demonstrate the new concept we quantify System LCOE from a simple power system model and literature values. We find that at high wind shares integration costs can be in the same range as generation costs of wind power and conventional plants in particular due to a cost component "profile costs" captured by the new definition. Integration costs increase with growing wind shares and might become an economic barrier to deploying VRE at high shares. System LCOE help understanding and resolving the challenge of integrating VRE and can guide research and policy makers in realizing a cost-efficient transformation towards an energy system with potentially high shares of variable renewables.}, language = {en} } @article{AmbergausdemMooreBekketal., author = {Amberg, Maximilian and aus dem Moore, Nils and Bekk, Anke and Bergmann, Tobias and Edenhofer, Ottmar and Flachsland, Christian and George, Jan and Haywood, Luke and Heinemann, Maik and Held, Anne and Kalkuhl, Matthias and Kellner, Maximilian and Koch, Nicolas and Luderer, Gunnar and Meyer, Henrika and Nikodinoska, Dragana and Pahle, Michael and Roolfs, Christina and Schill, Wolf-Peter}, title = {Reformoptionen f{\"u}r ein nachhaltiges Steuer- und Abgabensystem.
