Renewable energy sources

The concept of Integrated Food and Energy Systems (IFES) as such is not new. Simple integration of food and energy production at both small and large scales has shown many successful results. However, with the increasing complexity of the system, - and hence higher resource use efficiency, the number of successful cases diminishes. Concrete results on wide-scale implementation of more complex IFES are scarce.

From introduction: "WWF has a vision of a world that is powered by 100 per cent renewable energy sources by the middle of this century. Unless we make this transition, the world is most likely to avoid predicted escalating impacts of climate change. But is it possible to achieve 100 per cent renewable energy supplies for everyone by 2050? WWF called on expertise of respected energy consultancy Ecofys to provide an answer this question.

Part 1 of this final report outlines current global environmental problems and serves as an introduction to the entire report. Part 2 gives the results of the Conference discussions. Chapter 1 summarizes the data and reference materials that were submitted to the Conference, and demonstrates how serious current environmental problems are by giving actual data on global warming, loss of biodiversity and others. Chapters 2 and 3 summarize the results of the discussions.

The key message of this publication is that the occurrence of the global economic and financial crisis and the interrelated climate, food, and water crises offers a window of opportunity to embark on a path of more resilient and sustainable economic growth. The key challenge is to avoid responding to the crises with measures that perpetuate economically, socially and environmentally unsustainable production and consumption patterns.

This paper explores the pros and cons of biomass and the logistics of switching to other fuels in developing countries.

With the support of the Altener Programme of the European Commission, this elucidates the Island 2010 campaign, whose aim is to promote, identify and consolidate the strategy "Towards 100% Renewable Energy Sources Supply" in island territories.

La transformación de los residuos de la actividad forestal y de la biomasa abandonada en los montes en un recurso con posibilidades de aprovechamiento energético supone ejercer una gestión eficiente de los bosques y plantaciones forestales, generando además beneficios medioambientales y económicos. Estudio realizado por un equipo interdisciplinar de expertos, autores también de la publicación anterior del CIEF Beneficios y costes sociales en la conservación de la Red Natura 2000.
