    Design of effective energy efficiency policies
    (Fraunhofer Verlag, 2014)
    Schlomann, Barbara
    Energy efficiency is widely acknowledged as the most important strategy for achieving global energy and climate targets. Apart from its contribution to the reduction of energy consumption and energy-related greenhouse gas emissions (GHG), improving energy efficiency can deliver a range of co-benefits to the economy and society. There are, however, indications that energy efficiency policy is still insufficiently anchored both in the EU and many Member States as well as at an international level. This thesis focuses on the question how to create more favourable preconditions for an effective anchoring of energy efficiency policy in energy and climate policy. The design of energy efficiency policies is analyzed in the frame of the setting of energy efficiency targets and the monitoring and evaluation of their success. This provides new insights in the functioning of policies and hence their improvement in view of target achievement.

    The adoption of energy-efficient technologies by firms
    (Fraunhofer Verlag, 2012)
    Fleiter, Tobias
    The deployment of energy-efficient technology is a key strategy to reduce greenhouse gas emissions. This thesis analyzes the adoption and diffusion of energy-efficient technologies by firms and derives recommendations for policy makers. It provides new insights by taking a broad perspective that considers technologies and their characteristics as well as the decision-making behavior of firms in an integrated approach.

    No-lose targets as an option to integrate non-Annex I countries in global emission reduction efforts
    (Fraunhofer Verlag, 2012)
    Duscha, Vicki
    Substantial greenhouse gas emission reductions of 50% and more below 1990 levels by 2050 are necessary, to limit mean temperature increase below 2°C above pre-industrial levels. While the Kyoto Protocol foresees emission reduction targets for Annex I countries only, current and projected greenhouse gas emissions, as well as the growing economic importance of emerging economies call for an integration of non-Annex I countries in global reduction efforts. No-lose targets set emission reduction targets and define incentives for meeting the target, in contrast to binding reduction targets that use penalties to ensure compliance. One form of incentive is the participation in an international emissions trading market. While a few conceptual and quantitative analyses of no-lose targets can be found in the literature, economic analyses have not been carried out so far. In this thesis, two theoretical frameworks are introduced to analyze the potential of no-lose targets to contribute to global emission reduction efforts. First, a two-player, two-stage model is developed to model a non-Annex I country's participation decision and derive the contribution to global emission reductions. Then a two-player participation game is introduced to analyze the effects that the participation decision of one non-Annex I country has on another non-Annex I country also facing a no-lose target. Two market forms, a perfectly competitive market, and a market with market power on the side of the non-Annex I country are analyzed. In order to complement the highly stylized theoretical frameworks, a quantitative analysis applying marginal abatement cost curves is conducted to estimate the contribution of no-lose targets to reaching the 2°C target. The analyses show that no-lose targets can result in substantial contributions from non-Annex I countries to global emission reductions, in particular if the reduction potential in the non-Annex I countries is large, compared to that of the Annex I community. Market power on the part of the non-Annex I countries is found to further increase these contributions. Yet large certificate transfers via the carbon market are necessary to make the no-lose targets profitable.

    Modelling the future development of renewable energy technologies in the European electricity sector using agent-based simulation
    (Fraunhofer Verlag, 2011)
    Held, A.M.
    Entscheidungen im Energiebereich müssen in der Regel unter Beachtung mehrerer, teilweise konfliktärer Zielsetzungen, wie Wirtschaftlichkeit, Versorgungsicherheit und Umweltschutz, getroffen werden. Vor diesem Hintergrund wird in der vorliegenden Arbeit ein multikriterielles Entscheidungsunterstützungssystem entwickelt und angewendet. Dabei liegt ein besonderer Fokus auf der adäquaten Berücksichtigung des technologischen Wandels im Rahmen der multikriteriellen Bewertung von Energietechnologien.
