Photovoltaics beat biofuels at converting sun's energy to miles driven

ScienceDaily: In 2005, President George W. Bush and American corn farmers saw corn ethanol as a promising fossil fuel substitute that would reduce both American dependence on foreign oil and greenhouse gas emissions. Accordingly, the 2005 energy bill mandated that 4 billion gallons of renewable fuel be added to the gasoline supply in 2006. That rose to 4.7 billion gallons in 2007 and 7.5 billion in 2012. Since then, life cycle assessments (LCAs) have shown that corn ethanol has modest if any effect on reducing...

Tree seeds offer potential for sustainable biofuels

ScienceDaily: Tree seeds, rather than biomass or fuel crop plants, could represent an abundant source of renewable energy, according to research published in the International Journal of Automotive Technology and Management. The study suggests that seeds from the Indian mahua and sal trees have almost as good a thermal efficiency as biodiesel but would produce lower emissions of carbon monoxide, waste hydrocarbons and NOx (nitrogen oxides). Sukumar Puhan of the GKM College of Engineering and Technology and...

Growing biofuels can make you ill

Climate News Network: Biofuels -- the green low-carbon alternative to fossil fuels -- could both damage human health and reduce crop yields, British scientists warn in the journal Nature Climate Change. They calculate that widespread introduction of plantations of fast-growing trees for ethanol, diesel and methane production could increase concentrations of ground-level ozone, resulting in millions of tonnes in crop losses and an additional 1,385 deaths per year. The sums are notional, and the research is intended...
