During trilateral discussions in 2006, the Government of Brazil, the European Commission (representing the European Union) and the Government of the United States of America affirmed their belief that the current market for biofuels is viable, the market will continue to grow within regions, and that international trade in biofuels would increase significantly by the end of the decade. In February 2007, a conference was organized by the European Commission and the European Committee for Standardization (CEN), with the active participation of the U.S. National Institute of Standards and Technology (NIST) and the Brazil’s National Institute of Metrology, Standardization, and Industrial Quality (INMETRO). This meeting, held in Brussels, convened a broad range of private-sector biofuels experts and government representatives from the EU, US and Brazil. The participants identified that differing standards for biofuels were a potential handicap to the free circulation of biofuels among the three regions. To support the global trade of biofuels, representatives of Brazil, the EU and the U.S. agreed to promote, whenever possible, the compatibility of biofuels-related standards in their respective regions. Such compatibility would not only facilitate the increasing use of biofuels in each of the regional markets, but also would support both exporters and importers of biofuels by helping to avoid adverse trade implications in a global market.

An interdisciplinary MIT faculty group examined the role of coal in a world where constraints on carbon dioxide emissions are adopted to mitigate global climate change. This follows “The Future of Nuclear Power” which focused on carbon dioxide emissions-free electricity generation from nuclear energy and was published in 2003. This report, the future of coal in a carbon-constrained world, evaluates the technologies and costs associated with the generation of electricity from coal along with those associated with the capture and sequestration of the carbon dioxide produced coal-based power generation. Growing electricity demand in the U.S. and in the world will require increases in all generation options (renewables, coal, and nuclear) in addition to increased efficiency and conservation in its use. Coal will continue to play a significant role in power generation and as such carbon dioxide management from it will become increasingly important. This study, addressed to government, industry and academic leaders, discusses the interrelated technical, economic, environmental and political challenges facing increased coal-based power generation while managing carbon dioxide emissions from this sector.

Energy policy is facing major challenges. Industrial countries are increasingly dependent on imports of oil and gas, and global warming is becoming more of a reality. In order to address these challenges, a sustainable energy system must be developed. This document presents an outline of a sustainable energy situation for Europe in the year 2050. The research institutes ECN and NRG hope that this vision will guide energy research and inspire both businesses and governments. The authors describe a consistent development path that leads to a reduction in CO₂ emissions in Europe to 60% below 1990 levels, and to a signifi cantly reduced level of oil and gas imports. However, in 2050 the energy system will not be completely sustainable. The authors have formulated additional sustainability conditions for the reliable use of nuclear energy, biomass, and CO₂ capture & storage in a sustainable energy system. If these conditions are complied with, the overall picture will meet realistic criteria of sustainability. Despite this, continued energy conservation and further development of renewables should be pursued after 2050. In the vision for 2050 presented here, much weight is given to new technologies, new resources and new energy infrastructure. In addition to such innovation, new ways of decision-making and new patterns of behaviour are essential. With respect to technological developments that result in, for instance, affordable solar cells, the deployment of second-generation biofuels and reliable CO₂ capture & storage, realistic judgements have been made as to the timing of their commercialisation. The technology policy required to bring about such technological developments is briefly outlined.

The environmental benefits of renewable energy are well known.

But the contribution that  they can make to energy security is less widely recognised.

This report aims to redress the  balance, showing how in electricity generation, heat supply, and transport, renewables can enhance energy security and suggesting policies that can optimise this contribution.

This publication highlights the potential contribution of bioenergy to world energy demand.

It summarises the wide range of biomass resources available and potentially available, the conversion options, and end-use applications.

Associated issues of market development, international bioenergy trade, and competition for biomass are also presented.

Finally, the potential of bioenergy is compared with other energy supply options.
