| Summary/Abstract |
With biomass staying high in the EU political agenda and most of the recent documents acknowledging that it has the potential to make a very significant contribution to reaching the 20% target, the issue of supply in terms of feedstock types, availability constraints and costs in different Member States is set to determine the future technology uptake and market deployment prospects.
This paper is based on one of the initial studies, 'Bioenergy's role in the EU market. A view of developments until 2020', and presents a structured review for EU biomass resources, aiming to map technical potentials and provide detailed information on availability, costs and future trends for biomass potentials of different residual feedsctocks in EU27.

| Summary/Abstract |
ecent research has employed estimates of media exposure to explore the relationship between information disseminated ‘from above’ and political violence. I argue that those methods involve a potential pitfall, i.e., the possibility that the variable that they measure, media availability, is an inadequate proxy for media consumption, the actual variable of interest. I further argue that researchers often cannot be confident that that proxy is a valid one unless they have a deep qualitative understanding of media consumption habits of the population under study. I illustrate that concern by examining recent research on genocide in Rwanda.

| Summary/Abstract |
This paper estimates a cumulative supply curve for conventional oil in the Central and South American (CSA) region. The curve includes volumes from provinces not previously assessed by other organizations, as well as reserve growth. Volumes for the previously unassessed provinces are estimated using a variable shape distribution (VSD) model. Then the volumes are allocated to CSA countries based on each country's share of proved reserves. Figures provided by the cumulative supply curve are stock variables for all time, unlike the traditional supply curve where they are flow variables that can continue from one period to the next. In this study, the fixed stock approach is used since it provides practical information with respect to the concerns that some have expressed about oil scarcity in the near future. Results indicate that Central and South American oil is more abundant than often assumed, and can be produced at costs below current market oil prices, and substantially below mid-2008 prices.

| Summary/Abstract |
To date, most of the existing wind farms have been built on-land but during the last few years many countries have also invested in offshore applications. The shift towards offshore wind project developments has mainly been driven by European energy policies, especially in north-west countries. In offshore sites the winds are stronger and steadier than on-land, making wind farms more productive with higher capacity factors. On the other hand, although offshore wind energy is not in its infancy period, most of the costs associated with its development are still much higher from onshore counterparts; however some recent technological progress may have the potential to narrow this gap in the years to come. In the present work, an overview of the activity noted in the field of offshore wind energy is carried out, with emphasis being given on the current status and future trends of the technology employed, examining at the same time energy production and availability issues as well as economic considerations.
