Available in PDF, EPUB and Kindle. Book excerpt: The production of energy feedstocks and fuels requires substantial water input. Not only do biofuel feedstocks like corn, switchgrass, and agricultural residues need water for growth and conversion to ethanol, but petroleum feedstocks like crude oil and oil sands also require large volumes of water for drilling, extraction, and conversion into petroleum products. Moreover, in many cases, crude oil production is increasingly water dependent. Competing uses strain available water resources and raise the specter of resource depletion and environmental degradation. Water management has become a key feature of existing projects and a potential issue in new ones.

Download or read book Biofuels written by Mark E. Gaffigan and published by DIANE Publishing. This book was released on 2010 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: In December 2007, the Congress expanded the renewable fuel standard (RFS), which requires rising use of ethanol and other biofuels, from 9 billion gallons in 2008 to 36 billion gallons in 2022. To meet the RFS, the Departments of Agriculture (USDA) and Energy (DOE) are developing advanced biofuels that use cellulosic feedstocks, such as corn stover and switchgrass. The EPA administers the RFS. This report examines, among other things: (1) the effects of increased biofuels production on U.S. agriculture, environment, and greenhouse gas emissions; (2) federal support for domestic biofuels production; and (3) key challenges in meeting the RFS. Includes recommendations. Charts and tables.

Book excerpt: In response to concerns about the nation¿s energy dependence on imported oil, and climate change, the fed. gov¿t. has encouraged the use of biofuels. Water plays a crucial role in all stages of biofuel production -- from cultivation of feedstock through its conversion into biofuel. As demand for water from various sectors increases and places additional stress on already constrained supplies, the effects of expanded biofuel production must be considered. This report examined: (1) water resource effects of biofuel production in the U.S.; (2) agr. conservation practices and technological innovations that could address these effects and any barriers to their adoption; and (3) research needs regarding the effects of water resources on biofuel production.
Download or read book Life Cycle Water Impacts of U S Transportation Fuels written by Corinne Donahue Scown and published by . This book was released on 2010 with total page 554 pages. Available in PDF, EPUB and Kindle. Book excerpt: The connection between energy use and water scarcity is not well understood. The production of energy requires water and the supply of water requires energy. Water already plays a major role in stationary energy production; thermoelectric power generation is responsible for nearly half of total freshwater withdrawals in the United States. Current transportation fuels, which account for approximately one-third of U.S. energy consumption, are not nearly as reliant on freshwater given that petroleum fuel production makes up just a few percent of U.S. water use. If transportation were to become more reliant on water-intensive sectors such as power generation and agriculture, there would be major implications for water availability in the United States. As electricity and biofuels gain a larger share of the market, this is exactly the transition that is taking place. Inconsistent water use metrics, inappropriate impact allocation practices, limited system boundaries due to lack the necessary tools and data, and the failure to quantify water resource availability and greenhouse gas (GHG) impacts are common pitfalls of existing assessments of transportation energy-related water use. To fill the knowledge gaps, this dissertation proposes a comprehensive life-cycle framework for assessing the water withdrawals and consumption of current and near-future U.S. transportation fuels -- including gasoline, bio-based ethanol, and electricity. With this proposed framework for performing a life-cycle inventory and impact assessment, the following three questions are answered: 1. What is the life-cycle water footprint of current and near-future transportation fuel production in the United States? 2. How might U.S. transportation fuel production pathways impact freshwater availability in the future? 3. What is the greenhouse gas-intensity of the water required for transportation fuel production, and how do these emissions impact the overall transportation fuel greenhouse gas footprints? Understanding the impacts of water use on freshwater resources and GHG emissions requires knowledge of not only the fuel production pathways, but also how these pathways interact with other sectors in the economy. As new transportation fuels emerge, demand for some goods and services will increase while for others it will decrease, and each change has an effect on overall water demand. Quantifying the net system-wide impact of producing these new fuels is key to understanding the water implications of transportation energy-related policy decisions. Furthermore, by geospatially disaggregating predicted water requirements for transportation fuel production pathways at the U.S. county-level, locations within the United States can be identified as vulnerable to local surface and groundwater shortages. These shortages may result in high water prices and the need for energy-intensive water supply methods such as desalination, importation, or wastewater recycling. Identifying regions with vulnerable water resources allows decision makers in industry and the public sector to guide burgeoning transportation fuel markets in ways that maximize their contributions to energy independence and greenhouse gas emissions reductions while avoiding negative impacts on water availability. Results from the U.S. analysis show that indirect water use has a significant impact on total water use, particularly for withdrawals. In no other pathway is this as pronounced as it is for cellulosic ethanol production (in this case, corn stover and Miscanthus to ethanol). By using system expansion to account for the electricity generation displaced by cellulosic biorefineries' exports to the grid, total water consumption for those pathways drops considerably and total withdrawals actually becomes a net negative number. When the inventory is geospatially disaggregated and compared to drought and groundwater vulnerability data, the results show that biofuel production concentrated in the Midwest puts pressure on the already-overpumped High Plains Aquifer. Petroleum fuel production pathways result in water use concentrated in locations that are predicted to experience long-term drought, specifically California, Texas, and Wyoming. Electricity, in contrast, is more widely distributed throughout the U.S., but the high surface water consumption rates in the western half of the country may exacerbate future surface water shortages in those regions. Gaining a better knowledge of how the production and consumption of fuels impacts freshwater resources is absolutely critical as humans attempt to transition into a more sustainable energy future. By making contributions to the methodologies required to assess the environmental impacts of water use, as well as knowledge about the potential water impacts of current and near-future U.S. transportation fuels, this dissertation provides U.S. decision makers with information necessary to create the most economical and sustainable transportation energy future possible while also providing future researchers with the tools to answer questions that have yet to be asked.

Available in PDF, EPUB and Kindle. Book excerpt: This research report examines the economic and environmental externalities associated with the US transportation sector. The United States currently accounts for about 25 percent of world oil consumption, about 50 percent of which is imported. Achieving energy security by reducing dependence on imported oil has been the foremost challenge of several major energy-importing countries, including the United States. In this study, we explored the costs associated with energy security/cost of dependence on oil and estimated the environmental externalities associated with different types of transportation fuels based on a set of economic, environmental, and life-cycle analysis models. Our assessment of estimations on oil dependence costs indicates that several elements constitute the true cost of oil and not many studies have attempted to include all of these costs for various reasons. For analyzing the environmental externalities, we used a life-cycle analysis model; the FASOM-GHG model of agriculture and forestry; APEEP—an integrated assessment model to calculate the marginal damage of emissions; GTAP-BIO—a computable general equilibrium model to estimate land use changes; and the OSIRIS model to estimate the species extinctions based on deforestation. This study on assessing the externalities could provide a quantitative basis for policy initiatives pertaining to America’s future transportation infrastructure. This study suggests that there is a need to consider economic, environmental, and other societal costs within a holistic framework to assess relative costs and benefits and suitability of alternative transportation fuels that could play a role in meeting our future energy needs.

Download or read book Energy and Water Preliminary Observations on the Links Between Water and Biofuels and Electricity Production written by Anu Mittal and published by DIANE Publishing. This book was released on 2009-11 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water and energy are inexorably linked -- energy is needed to pump, treat, and transport water and large quantities of water are needed to support the development of energy. Two examples that demonstrate the link between water and energy are the cultivation and conversion of corn, switchgrass, and algae into biofuels; and the production of electricity by thermoelectric power plants. There are three ongoing studies focusing on the water-energy nexus related to: (1) biofuels and water; (2) thermoelectric power plants and water; and (3) oil shale and water. This testimony provides the key themes that have emerged from work to date on the R&D and data needs with regard to the production of biofuels and electricity and their linkage with water.

Download or read book Renewable Fuel Standard written by National Research Council and published by National Academies Press. This book was released on 2012-01-29 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Water Quality Impacts of the Energy Water Nexus written by Avner Vengosh and published by Cambridge University Press. This book was released on 2022-02-24 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: Energy and water have been fundamental to powering the global economy and building modern society. This cross-disciplinary book provides an integrated assessment of the different scientific and policy tools around the energy-water nexus. It focuses on how water use, and wastewater and waste solids produced from fossil fuel energy production affect water quality and quantity. Summarizing cutting edge research, it describes the scientific methods for detecting contamination sources in the context of policy and regulations. The authors highlight the growing evidence that fossil fuel production, from both conventional and unconventional sources, leads to water quality degradation, while regulations for the water and energy sector remain fractured and highly variable across and within countries. This volume will be a key reference for scholars, industry professionals, environmental consultants and policy makers seeking information on the risks associated with the energy cycle and its impact on the environment, particularly water resources.

This book was released on 2010-09-15 with total page 462 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a collection of chapters concerning the use of biomass for the sustainable production of energy and chemicals–an important goal that will help decrease the production of greenhouse gases to help mitigate global warming, provide energy security in the face of dwindling petroleum reserves, improve balance of payment problems and spur local economic development. Clearly there are ways to save energy that need to be encouraged more. These include more use of energy sources such as, among others, manure in anaerobic digesters, waste wood in forests as fuel or feedstock for cellulosic ethanol, and conservation reserve program (CRP) land crops that are presently unused in the US. The use of biofuels is not new; Rudolf Diesel used peanut oil as fuel in the ?rst engines he developed (Chap. 8), and ethanol was used in the early 1900s in the US as automobile fuel [Songstad et al. (2009) Historical perspective of biofuels: learning from the past to rediscover the future. In Vitro Cell Dev Biol Plant 45:189–192). Brazil now produces enough sugar cane ethanol to make up about 50% of its transportation fuel needs (Chap. 4). The next big thing will be cellulosic ethanol. At present, there is also the use of Miscanthus x giganteous as fuel for power plants in the UK (Chap. 2), bagasse (sugar cane waste) to power sugar cane mills (Chap. 4), and waste wood and sawdust to power sawmills (Chap. 7).
