Renewable Fuel Standard


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


Book Description

Biofuel is a renewable energy source produced from natural materials. The benefits of biofuels over traditional petroleum fuels include greater energy security, reduced environmental impact, foreign exchange savings, and socioeconomic issues related to the rural sector. The most common biofuels are produced from classic food crops that require high-quality agricultural land for growth. However, bioethanol can be produced from plentiful, domestic, cellulosic biomass resources such as herbaceous and woody plants, agricultural and forestry residues, and a large portion of municipal and industrial solid waste streams. There is also a growing interest in the use of vegetable oils for making biodiesel. “Biofuels: Securing the Planet’s Future Energy Needs” discusses the production of transportation fuels from biomass (such as wood, straw and even household waste) by Fischer-Tropsch synthesis. The book is an important text for students and researchers in energy engineering, as well as professional fuel engineers.




Can Biofuels Alleviate the Energy and Environmental Crisis?


Book Description

Climate change is one of the major challenges society is facing currently. Major spheres of human activity such as health, environment, agriculture, economy, transportation and education were adversely affected because of climate change. Environmental pollution owing to the indiscriminate and ever-increasing consumption of fossil-based resources is the main factor contributing to climate change. Use of fuels produced from renewable sources like biomass cause reduction in CO2 emission and guarantee sustainable energy and a clean environment. The problems of environmental deterioration, as well as energy demands, could be alleviated by the paradigm shift to the use of biofuels from fossil fuels. Innovative strategies were recently developed for the exploitation of biomass for biofuels production. The concept of biomass itself is being understood in an unconventional sense in a way that apart from terrestrial plant resources, marine macroalgae, freshwater microalgae, industrial emissions like CO2, organic remains like glycogen are being explored as feedstock for biofuels production. Biofuel production strategies are also undergoing drastic changes like the use of solar radiation, sonochemical, microwave and accelerated electron beam irradiations to meet the fuel demand and to make the biomass conversion processes more energy- and atom-efficient and sustainable. The objective of the compilation of the book titled "Can Biofuels Alleviate The Energy & Environmental Crisis?" is to reach out to policy makers, scientists, industrialists, and students with a message as well as scientific strategies for alleviating the twin problems of energy and environmental crisis posing a threat to future generations. The book comprises of seven judiciously designed chapters focused on producing biofuels (biodiesel, bioethanol, formic acid, synthesis gas, methane, and ethylene) and biochemicals (glucose, levulinic acid) using feedstock as diverse as lignocellulosic terrestrial biomass, marine macroalgae, glycogen, and CO2. Biomass is an ideal substitute to fossil mass as almost all the products derived from conventional refinery could be produced in a biorefinery using biomass as a carbon source. In addition to being sustainable, the biorefinery facilities are environmentally benign. The biomass conversion strategies proposed in this book facilitate the paradigm shift from fossil-based to biobased industries and help the proliferation of biorefinery facilities in the 21st century, offering a pathway for the alleviation of the problem of climate change.

Sustainable Development of Algal Biofuels in the United States


Book Description

Biofuels made from algae are gaining attention as a domestic source of renewable fuel. However, with current technologies, scaling up production of algal biofuels to meet even 5 percent of U.S. transportation fuel needs could create unsustainable demands for energy, water, and nutrient resources. Continued research and development could yield innovations to address these challenges, but determining if algal biofuel is a viable fuel alternative will involve comparing the environmental, economic and social impacts of algal biofuel production and use to those associated with petroleum-based fuels and other fuel sources. Sustainable Development of Algal Biofuels was produced at the request of the U.S. Department of Energy.
