Farmers in the United States sometimes plant switchgrass as a border crop. But could this tall grass lower the nation’s dependence on foreign oil? The department of the energy plants to invest hundreds of millions of dollars to help produce fuels from the materials that are not part of the food’s supply.
Growing corn or maize for fuel has raised concerns above the supply and cost of corn available for food and animal fee. Fuel made from switchgrass or forestry waste like / is known as / ethanol..
Department officials say it contains more energy and produces fewer green house gases than ethanol made from corn. Switchgrass is also easier to grow.
Last month, the procedings of the national academy of scientings published a study of switchgrass grow on low quality land. Government scientist / was the lead author. The study says the switchgrass produced five times more energy than was needed to grow it. Also it says switchgrass over its life time from crop to fuel produces much less carbon compare to gasoline.
Fossil fuels like oil take carbon from the ground and release it as waste gas when the fuel is burned. Biofuels like corn and // ethanol also produce green house gases through growing crops are making the fuel.
The defferences are the biofuels remove carbon from the / / through the growth of the feeds / , the material for the fuel. Sicence magazine just published two studies of biofuels and the hit traping gases. The scientists link to clime changes. One of the reports notes that most studies have found that substituting biofuels for gasoline will reduce green house gases, but it says the earlier studies fail to count the carbon released into the / /. As farmers worldwide react to higher prices. They are clearing forests and grass lands to make way for new crop land to replace the grain used for biofuels. Doing so can release much of the carbon stored in the plants and soil and sacrifice future storage.
The study found that corn based ethanol could increase green house gases for years from land use change and it found that biofuels from switchgrass if grow on american corn land could also increas / though by less.
The study team led by / at Princeton university says the result shows that value of using waste product for fuel, the other reports says carbon savings depend on how biofuels are produced.
