Renewable Fuel Standard
Author: National Research Council
Publisher: National Academies Press
ISBN: 0309187516
Category : Technology & Engineering
Languages : en
Pages : 416
Book Description
In the United States, we have come to depend on plentiful and inexpensive energy to support our economy and lifestyles. In recent years, many questions have been raised regarding the sustainability of our current pattern of high consumption of nonrenewable energy and its environmental consequences. Further, because the United States imports about 55 percent of the nation's consumption of crude oil, there are additional concerns about the security of supply. Hence, efforts are being made to find alternatives to our current pathway, including greater energy efficiency and use of energy sources that could lower greenhouse gas (GHG) emissions such as nuclear and renewable sources, including solar, wind, geothermal, and biofuels. The United States has a long history with biofuels and the nation is on a course charted to achieve a substantial increase in biofuels. Renewable Fuel Standard evaluates the economic and environmental consequences of increasing biofuels production as a result of Renewable Fuels Standard, as amended by EISA (RFS2). The report describes biofuels produced in 2010 and those projected to be produced and consumed by 2022, reviews model projections and other estimates of the relative impact on the prices of land, and discusses the potential environmental harm and benefits of biofuels production and the barriers to achieving the RFS2 consumption mandate. Policy makers, investors, leaders in the transportation sector, and others with concerns for the environment, economy, and energy security can rely on the recommendations provided in this report.

Biofuels in Africa
Author: Donald Mitchell
Publisher: World Bank Publications
ISBN: 0821385178
Category : Business & Economics
Languages : en
Pages : 220
Book Description
A new economic opportunity for sub-Saharan Africa is looming large: biofuel production. Rapidly rising energy prices are expected to remain high for an extended period of time because of the increasing demand in prospering and populous countries such as China and India, the depletion of easily accessible supplies of crude oil, and concern over global climate change. As a result, there is renewed interest in biofuels as an alternative to fossil fuels. Africa is uniquely positioned to produce these new cash crops for both domestic use and export. The region has abundant land resources and preferential access to protected markets with higher-than-world-market prices. The rapid growth in the demand for transport fuels in Africa and high fuel prices create domestic markets for biofuels. The European Union and the United States have approved legislation that requires large increases in the consumption of biofuels over at least the next decade. Imports are expected to be needed to meet these mandates, thus opening the door to African and other developing countries that can produce biofuels or feedstocks for biofuels competitively. Expanding the production of crops for biofuels will affect the entire rural sector in Africa as resources are shifted away from traditional crops and the prices of all agricultural commodities rise. Even smallholders can participate in producing biofuel crops. To promote the sustainability and significant contribution of this enterprise, Biofuels in Africa provides guidance in formulating suitable policy regimes, which are based on protecting the rights of current land users, developing revenue-sharing schemes with local communities, safeguarding the environment and biodiversity, expanding institutional capacity, formulating new regulations and procedures, and emulating best practices from experienced countries. This volume will be of value to anyone interested in biofuels, including policy makers, development practitioners, private investors, researchers, and the general public. Now that African countries are trying to significantly increase their energy supply systems, biofuels are an attractive option using both dedicated crops and agricultural waste. This book provides guidance for them to develop a suitable policy regime for a significant contribution by biofuels. Professor Ogunlade R. Davidson, Minister of Energy and Water Resources, Sierra Leone Biofuels in Africa is a sorely needed resource for our understanding of the problems of expanding biofuels production in Africa. A high point of the book is a description of the projects that were started in several countries. A very useful book! Professor Jos Goldemberg, University of S o Paulo, Brazil As Africa most likely will play the same role for global biofuels as the Middle East does for oil, this comprehensive book on African biofuels should be compulsory reading for anyone interested in either African development or biofuels. The book captures the essence of long-term drivers and opportunities as well the complex challenges for investors and society of this huge emerging industry.

Commercial Aircraft Propulsion and Energy Systems Research

ISBN: 0309440998
Category : Technology & Engineering
Languages : en
Pages : 123
Book Description
The primary human activities that release carbon dioxide (CO2) into the atmosphere are the combustion of fossil fuels (coal, natural gas, and oil) to generate electricity, the provision of energy for transportation, and as a consequence of some industrial processes. Although aviation CO2 emissions only make up approximately 2.0 to 2.5 percent of total global annual CO2 emissions, research to reduce CO2 emissions is urgent because (1) such reductions may be legislated even as commercial air travel grows, (2) because it takes new technology a long time to propagate into and through the aviation fleet, and (3) because of the ongoing impact of global CO2 emissions. Commercial Aircraft Propulsion and Energy Systems Research develops a national research agenda for reducing CO2 emissions from commercial aviation. This report focuses on propulsion and energy technologies for reducing carbon emissions from large, commercial aircraftâ€" single-aisle and twin-aisle aircraft that carry 100 or more passengersâ€"because such aircraft account for more than 90 percent of global emissions from commercial aircraft. Moreover, while smaller aircraft also emit CO2, they make only a minor contribution to global emissions, and many technologies that reduce CO2 emissions for large aircraft also apply to smaller aircraft. As commercial aviation continues to grow in terms of revenue-passenger miles and cargo ton miles, CO2 emissions are expected to increase. To reduce the contribution of aviation to climate change, it is essential to improve the effectiveness of ongoing efforts to reduce emissions and initiate research into new approaches.
