Germany’s government and its oil industry association on Tuesday disagreed about whether the country can reach its 2011 biofuel use quotas as sales of a new gasoline blend with a higher biofuel content remain sluggish. (Reuters)
Testing the water for bioenergy crops
Water significant limiting factor in growing crops like switchgrass
Energy researchers and environmental advocates are excited about the prospect of gaining more efficient large-scale biofuel production by using large grasses like miscanthus or switchgrass rather than corn.
They have investigated yields, land use, economics and more, but one key factor of agriculture has been overlooked: water.
“While we are looking for solutions for energy through bioenergy crops, dependence on water gets ignored, and water can be a significant limiting factor,” said Praveen Kumar, an environmental engineer and atmospheric scientist at the University of Illinois at Urbana-Champaign. (EurekAlert)
Rising global demand for cleaner energy from biomass could drive more land acquisition in poorer nations where food security and land rights are weak, an International Institute for Environment and Development report said on Tuesday. (Reuters)
