This paper deals with the question, how to quantify the generated effects of value added and employment on a local scale. Value added is calculated as the sum of three components: tax revenues, company profits and wages, which are generated by the involved agents along the value chains of the examined RE technologies. The knowledge of local value added and employment effects can be an important factor concerning the acceptance or RE technologies as well as the further expansion of decentralized and renewable energy generation.

Different battery management strategies such as fixed power limitation, charging interval timer with regard to typical solar radiation profiles, maximizing self-consumption and maximizing the benefit for the grid have been implemented and analyzed.

RE contribute to the security of the energy supply as they reduce the use of fossil resources and nuclear energy, thus alleviating dependence on energy imports. They are also a very important future strategy to reduce greenhouse gases, therefore essential to meet the Kyoto-goals, to reduce climate change and to build up a sustainable energy system. The description of the future role and importance show that the policy field "RE" is deeply embedded in energy and climate policies in general - but it is not that prominent represented in the international arena, especially compared to the institutional settings of the conventional energy industries. RE are not represented by one "concentrated" organisation or an influential global network. In fact, a distinct lack of coordination and cooperation of activities can be observed, which leads to a lot of inefficiencies. There have been different suggestions on how to improve this situation. The discussion about the right path to gain such a global structure for the successful promotion has begun at the world summit in Johannesburg und especially around the international conference of the "Renewables 2004" in Bonn. While for example a global agency as part of the UN system presently seems to be far out of reach, solutions like a voluntary "frontrunner" network of interested states and private actors is discussed more concrete - and yet "under construction". But what seems to be a realistic, useful and necessary design that meets the needs of the (international) RE industry - and what kind of experiences can give consultancy to this process? The paper wants to analyse the current situation of the emerging global RE regime, discuss the various forms of global governance mechanism and will compare the situation with former experiences (success, failures, structures) of other (comparable) global (environmental) regimes.}, language = {en} } @inproceedings{HirschlHoffmann, author = {Hirschl, Bernd and Hoffmann, Esther}, title = {Promotion of Renewable Energies for Heating and Cooling}, series = {Networked knowledge for renewables energies, Science Forum of Renewables 2004, International Conference for Renewables Energies, Science Forum 2004 organized by the Solar Energy Research Association, ForschungsVerbund Sonnenenergie on 1st june in Bonn}, booktitle = {Networked knowledge for renewables energies, Science Forum of Renewables 2004, International Conference for Renewables Energies, Science Forum 2004 organized by the Solar Energy Research Association, ForschungsVerbund Sonnenenergie on 1st june in Bonn}, publisher = {FVS}, address = {Berlin}, pages = {61 -- 66}, language = {en} } @inproceedings{HirschlVogelpohl, author = {Hirschl, Bernd and Vogelpohl, Thomas}, title = {Voluntary Bioenergy Certification: A Legitimate Approach to Account for Social Aspects in Environmental Governance?}, series = {2010 Berlin Conference on the Human Dimensions of Global Environmental Change, 8.-9.

One potential solution for these problems that is increasingly discussed now is the certification of bioenergy. In the wake of this discussion, a broad range of certification initiatives emerged during the last years. However, this issue is predominantly debated in terms of the environmental implications. Accordingly, governmental approaches to this issue often neglect the need for including social aspects into sustainability principles and criteria, most prominently here the EU Renewable Energies Directive (RED). Non-state voluntary certification initiatives, by accounting for the social implications of increased bioenergy production, could therefore be seen as complementary governance instruments that are able to fill the void left by state regulations in this respect. After briefly addressing the reasons why state regulations tend to neglect social aspects concerning this matter, this presentation seeks to explore whether voluntary bioenergy certification schemes could really be able to fulfill these hopes and provide the solution for the missing consideration of social criteria for sustainable bioenergy. And how could these private non-state initiatives do so in a politically and democratically legitimate way? So as to deal with these issues from a scientific perspective, a distinct analytical framework to evaluate the legitimacy of private governance is presented. Based on this framework, five voluntary bioenergy certification schemes are selected and their consideration given to its social dimension is examined. In order to address the characteristics of our conception of non-state legitimacy, the actor constellations behind these certification initiatives are analyzed with a view to determine the structural representation of social interests. Furthermore, we also give attention to the control and accountability mechanisms incorporated into the certification schemes that are supposed to safeguard the common welfare-orientation of the initiatives. The results of this analysis shed some light on the particular challenges and bottlenecks of ensuring social sustainability via non-state voluntary certification systems in the bioenergy sector. In the concluding chapter, these results are put into perspective and a more general discussion on the potential of non-state voluntary governance approaches regarding the social dimension of environmental governance are presented.}, language = {en} } @inproceedings{HirschlDunkelbergFinkbeiner, author = {Hirschl, Bernd and Dunkelberg, Elisa and Finkbeiner, Matthias}, title = {Influence of Indirect Land Use Chance on the GHG Balance of Biofuels - A Review of Methods and Impacts}, series = {WREC World Renewable Energy Congress 2011, 8.-13.
