This book presents important new research on applied eco-efficiency concepts throughout Europe. The aim of eco-efficiency is to achieve market-based measures of environmental protection, in order to enhance the prospects for sustainable development and achieve positive economic and ecological benefits. The distinguished authors discuss a number of themes surrounding eco-efficiency including the necessary conditions for technological dissemination and ecological modernization, and the role of government in enabling businesses and society to participate actively in this process. In particular, they highlight the application of existing European-based policies concerning material flows and energy. The authors also investigate some new concepts of sustainable development and provide a useful introduction to material flows analysis. In further chapters they study the emerging regulatory policies for eco-efficiency, and examine the issues of sustainable business and consumption strategies.
Scenarios for the transition to a sustainable and climate protecting energy system in Germany
(2004)
The brochure focuses on the significance of the construction sector and aim to collect world-wide innovative project approaches that have already been implemented to promote the concepts. Using a key number of internationally accepted criteria, the main considerations have been the energy efficiency and in a broad sense also the resource efficiency of the projects.
Bridging the data gap
(2004)
In this second brochure, WISIONS aims to focus on the significance of a combined approach to water and energy and to present a number of projects from around the globe that have been successfully implemented, with the intention of further promoting the particular approaches used by these projects. Using a key number of internationally accepted criteria, the main consideration for selection of the projects was energy and resource efficiency, but social aspects such as the inclusion of local population were also of relevance. The assessment of the projects also included the consideration of regional factors acknowledging different needs and potentials.
New energy efficiency policies have been introduced around the world. Historically, most energy models were reasonably equipped to assess the impact of classical policies, such as a subsidy or change in taxation. However, these tools are often insufficient to assess the impact of alternative policy instruments. We evaluate the so-called engineering economic models used to assess future industrial energy use. Engineering economic models include the level of detail commonly needed to model the new types of policies considered. We explore approaches to improve the realism and policy relevance of engineering economic modeling frameworks. We also explore solutions to strengthen the policy usefulness of engineering economic analysis that can be built from a framework of multidisciplinary cooperation. The review discusses the main modeling approaches currently used and evaluates the weaknesses in current models. We focus on the needs to further improve the models. We identify research priorities for the modeling framework, technology representation in models, policy evaluation, and modeling of decision-making behavior.
Using natural gas for fuel releases less carbon dioxide per unit of energy produced than burning oil or coal, but its production and transport are accompanied by emissions of methane, which is a much more potent greenhouse gas than carbon dioxide in the short term. This calls into question whether climate forcing could be reduced by switching from coal and oil to natural gas. We have made measurements in Russia along the world's largest gas-transport system and find that methane leakage is in the region of 1.4%, which is considerably less than expected and comparable to that from systems in the United States. Our calculations indicate that using natural gas in preference to other fossil fuels could be useful in the short term for mitigating climate change.
Target 2020 : policies and measures to reduce greenhouse gas emissions in the EU ; final report
(2005)
In this brochure, WISIONS focuses on the significance of innovative strategies in the field of sustainable tourism. WISIONS presents projects from Tanzania, Germany, Ecuador, Switzerland and Ghana that have been successfully implemented, with the intention of further promoting the particular approaches used by these projects. Using a key number of internationally accepted criteria, the main consideration for the selection of the projects was energy and resource efficiency, but social aspects such as the inclusion of local population were also of relevance. The assessment of the projects also included the consideration of regional factors acknowledging different needs and potentials.
Under the framework of the UN framework convention on climate change (UNFCCC) and its Kyoto Protocol the targets and strategies for the second and third commitment period ("post-2012") have to be discussed and set in the near future. Regarding the substantial emission reductions that have to be shouldered by the industrialized nations over the next two decades it is evident that all available potentials to mitigate greenhouse gas (GHG) emissions have to be harnessed and that energy efficiency has to play a key role.
To substantiate this we developed a comprehensive scenario analysis of the EU 25s energy system and other greenhouse gas emissions until 2020. Our analysis shows which key potentials to mitigate greenhouse gas emissions are available, by which policies and measures they are attainable
and which will be benefits of greenhouse gas mitigation measures.
By this analysis we show the mayor role of energy efficiency in all sectors and all member states. We demonstrate that a reduction of EU 25 greenhouse gas emissions by more than 30 % by 2020 is feasible, reasonable and - to a large extent - cost effective. We also develop a comprehensive policy package necessary to achieve ambitious Post-Kyoto targets.
The scenario analysis results in a clear identification of the needed strategies, policies and measures and especially the relevance of energy efficiency to achieve the necessary ambitious greenhouse gas reduction targets. It also clearly shows the costs and the benefits of such a policy compared to a business as usual case.
Impacts of energy use on demand for freight transport : past development and future perspectives
(2005)
In this brochure, WISIONS focuses on the significance of innovative strategies in the field of sustainable transport. WISIONS presents a number of projects from around the globe that have been successfully implemented, with the intention of further promoting the particular approaches used by these projects. Using a key number of internationally accepted criteria, the main consideration for selection of the projects was energy and resource efficiency, but social aspects such as the inclusion of local population were also of relevance.

Based on different current long-term energy scenarios the paper discusses the future perspectives of hydrogen in the German energy system as a representative example for the development of sustainable energy systems. The scenario analysis offers varying outlines of the future energy system that determine the possible role of hydrogen. The paper discusses the possibilities of expanding the share of renewable energy and the resulting prospects for establishing clean hydrogen production from renewable energy sources. Emphasis is given to the questions of an ecologically efficient allocation of limited renewable energy resources that can only be assessed from asystems analysis perspective. Findings from recent studies for Germany reveal a strong competition between the direct input into the electricity system and an indirect use as fuel in the transport sector. Moreover, the analysis underlines the paramount importance of reducing energy demand as the inevitable prerequisite for any renewable energy system.
Renewables and off-grid rural electrification in developing countries : dimensions and trends
(2005)
In this brochure, WISIONS focuses on the significance of innovative strategies for saving energy in schools, including two types of projects: energy education projects and those that focus on sustainable energy technologies. WISIONS presents projects from India, France, Germany and Uganda that have been successfully implemented, with the intention of further promoting the particular approaches used by these projects. Using a key number of internationally accepted criteria, the main consideration for the selection of the projects was energy and resource efficiency, but social aspects such as the inclusion of pupils, teachers and parents were also of relevance. The assessment of the projects also included the consideration of regional factors acknowledging different needs and potentials.
Considering the enormous ecological and economic importance of the transport sector the introduction of alternative fuels - together with drastic energy efficiency gains - will be a key to sustainable mobility, nationally as well as globally. However, the future role of alternative fuels cannot be examined from the isolated perspective of the transport sector. Interactions with the energysystem as a whole have to be taken into account. This holds both for the issue of availability of energy sources as well as for allocation effects, resulting from the shift of renewable energy from the stationary sector to mobile applications. With emphasis on hydrogen as a transport fuel for private passenger cars, this paper discusses the energy systems impacts of various scenarios introducing hydrogen fueled vehicles in Germany. It identifies clear restrictions to an enhanced growth of clean hydrogen production from renewable energy sources (RES). Furthermore, it points at systems interdependencies that call for a priority use of RES electricity in stationary applications. Whereas hydrogen can play an increasing role in transport after 2030 the most important challenge is to exploit short–mid-term potentials of boosting car efficiency.
The role of hydrogen in long run sustainable energy scenarios for the world and for the case of Germany is analysed, based on key criteria for sustainable energy systems. The possible range of hydrogen within long-term energy scenarios is broad and uncertain depending on assumptions on used primary energy, technology mix, rate of energy efficiency increase and costs degression ("learning effects"). In any case, sustainable energy strategies must give energy efficiency highest priority combined with an accelerated market introduction of renewables ("integrated strategy"). Under these conditions hydrogen will play a major role not before 2030 using natural gas as a bridge to renewable hydrogen. Against the background of an ambitious CO2-reduction goal which is under discussion in Germany the potentials for efficiency increase, the necessary structural change of the power plant system (corresponding to the decision to phase out nuclear energy, the transformation of the transportation sector and the market implementation order of renewable energies ("following efficiency guidelines first for electricity generation purposes, than for heat generation and than for the transportation sector")) are analysed based on latest sustainable energy scenarios.
Microfinance and renewable energy : investing in a sustainable future ; WISIONS of sustainability
(2006)
In this brochure, WISIONS focuses on the micro financing of renewable energy systems. WISIONS presents projects from Peru, South Africa, China and Nepal that have been successfully implemented, with the intention of further promoting the particular approaches used by these projects. Using a key number of internationally accepted criteria, the main consideration for the selection of the microfinance projects was the inclusion of renewable energy technologies like solar/photovoltaic systems, wind energy and hydropower biogas used for cooking, lighting, power telecommunications equipment, radio, television, household electrification, health clinics, water pumping, milling and grinding, water disinfection, fencing, computer education, machinery operation, etc. in households or businesses.
Because of high efficiency, low environmental impacts and a potential role in transforming our energy system into a hydrogen economy, fuel cells are often considered as a key technology for a sustainable energy supply. However, the future framing conditions under which stationary fuel cells have to prove their technical and economic competitiveness are most likely characterised by a reduced demand for space heating, and a growing contribution of renewable energy sources to heat and electricity supply, which both directly limit the potential for combined heat and power generation, and thus also for fuelcells. Taking Germany as a case study, this paper explores the market potential of stationaryfuelcells under the structural changes of the energy demand and supply system required to achieve asustainable energy supply. Results indicate that among the scenarios analysed it is in particular a strategy oriented towards ambitious CO2-reduction targets, which due to its changes in the supply structure is in a position to mobilise a market potential that might be large enough for a successful fuel cell commercialisation. However, under the conditions of a business-as-usual trajectory the sales targets of fuel cell manufacturers cannot be met.
