Methods and tools to evaluate the availability of renewable energy sources

The recent statements of both the European Union and the US Presidency pushed in the direction of using renewable forms of energy, in order to act against climate changes induced by the growing concentration of carbon dioxide in the atmosphere. In this paper, a survey regarding methods and tools presently available to determine potential and exploitable energy in the most important renewable sectors (i.e., solar, wind, wave, biomass and geothermal energy) is presented. Moreover, challenges for each renewable resource are highlighted as well as the available tools that can help in evaluating the use of a mix of different sources

Emergence of European supergrids: essay on strategy issues

This paper looks at the technical and economic potential of supergrids for linking up and balancing the large renewable energy resource potentials in, around and near the EU, including in desert areas in N Africa and the Middle East. It explores the strategic and political pros and cons of what would be a major new development in international integration and trade

Battles over Biofuels in Europe: NGOs and the Politics of Markets

In this paper, we argue that a consortium of NGOs has played a significant role in shaping the market for, and restricting the use of, biofuels as an alternative to conventional fuels for road transport in Europe. This paper considers why a number of NGOs (Greenpeace, Oxfam, WWF, RSPB, Friends of the Earth) have chosen to enter the biofuels debate, and how they have variously developed policy, agreed a political campaign, and exercised political influence, in a key area of the world's response to major global climate change: how to reduce the carbon footprint of transport. We found that in many cases the development of NGO policy has been driven more by narrow political opportunities for influence than by broader and more coherent policy responses to global climate change or economic development, or indeed rigorous assessment of the scientific evidence. The research provides evidence of how NGO policies and lobbying significantly affected biofuel policy changes, review processes, target reductions, and sustainability regulation in the UK and in Europe. We consider that politically instituted markets, such as the one for biofuels, are examples of the emergence of new forms of governance of capitalist political economies facing a novel and pressing combination of drivers (climate change, energy security, resource constraints, and sustainable land-use). Politically instituted markets open up possibilities for political intervention from non-governmental or party-political actors, in ways that other markets do not. If political shaping of markets by NGOs becomes more widespread, issues of democratic legitimacy and public scrutiny will become ever more pressing. The paper is based on in-depth interviews with senior scientific directors and policy-makers in five NGOs, and of senior officials in UK government departments and the European Commission (DG Environment and DG Transport and Energy). It forms part of a wider ESRC research project in Brazil, the USA and Europe on the Transition to Sustainable Bioeconomies. </jats:p
