Biofuels and Ecosystem Carbon Balance Under Global Change
Terrestrial ecosystems are estimated to contain 3000 Pg of organic carbon (C) of which more than two thirds are stored in soils (Jobbágy and Jackson 2000). Total soil organic carbon (SOC) consists of different C pools with intrinsic turnover rates ranging from less than a year to thousands of years (Amundson 2001). The processes that drive the cycling of soil C are C inputs from net primary pro...
متن کاملCarbon-negative biofuels from low-input high-diversity grassland biomass.
Biofuels derived from low-input high-diversity (LIHD) mixtures of native grassland perennials can provide more usable energy, greater greenhouse gas reductions, and less agrichemical pollution per hectare than can corn grain ethanol or soybean biodiesel. High-diversity grasslands had increasingly higher bioenergy yields that were 238% greater than monoculture yields after a decade. LIHD biofuel...
متن کاملBiofuels
The global energy market provides humans with about 370 exajoules of energy per year, which is equivalent to about 170 million barrels of oil per day (Box 1) or about 11.73 terrawatts (TW) per hour [1]. Approximately 95% of this energy comes from fossil fuels. Additionally, the International Energy Agency suggests that direct combustion of plant biomass provides about one-third of the energy ne...

The United States’ primary transportation energy sources are fossil fuels, namely, gasoline and diesel. These products have high environmental, security, and financial costs. A strong emphasis has been placed on biofuels, especially ethanol and biodiesel, to lessen the United States’ reliance on fossil fuels. Historically, high production costs, lack of infrastructure, return on investment anxi...
