...change, biofuels have become the vanguard of the green-tech revolution, the trendy way for politicians and corporations to show they're serious about finding alternative sources of energy and in the process slowing global warming. The U.S. quintupled its production of ethanol--ethyl alcohol, a fuel distilled from plant matter--in the past decade, and Washington has just mandated another fivefold increase in renewable fuels over the next decade. Europe has similarly aggressive biofuel mandates and subsidies, and Brazil's filling stations no longer even offer plain gasoline. Worldwide investment in biofuels rose from $5 billion...
...when this deforestation effect is taken into account, corn ethanol and soy biodiesel produce about twice the emissions of gasoline. Sugarcane ethanol is much cleaner, and biofuels created from waste products that don't gobble up land have real potential, but even cellulosic ethanol increases overall emissions when its plant source is grown on good cropland. "People don't want to believe renewable fuels could be bad," says the lead author, Tim Searchinger, a Princeton scholar and former Environmental Defense attorney. "But when you realize we're tearing down rain forests that store loads of carbon to grow crops that...
...place to see this is America's biofuel mecca: Iowa. Last year fewer than 2% of U.S. gas stations offered ethanol, and the country produced 7 billion gal. (26.5 billion L) of biofuel, which cost taxpayers at least $8 billion in subsidies. But on Nov. 6, at a biodiesel plant in Newton, Iowa, Hillary Rodham Clinton unveiled an eye-popping plan that would require all stations to offer ethanol by 2017 while mandating 60 billion gal. (227 billion L) by 2030. "This is the fuel for a much brighter future!" she declared. Barack Obama immediately criticized her--not for proposing...
...recorded an album to accompany the tour. It topped the Billboard world-music chart in a matter of days. Then came sold-out tours of the U.S., Europe and Asia; Grammies for their next two albums, Blessed and African Spirit; concerts and recordings with stars like Bono and Robert Plant; and private shows for Bill Clinton and Nelson Mandela. So great was the demand that the choir has taken on 20 more singers and split into two, enabling it to plan simultaneous tours of the U.S. and Europe for later this year...
...first impressions of Baghdad Everything kind of became very day-to-day very quickly. When I was a platoon leader, I lived in a converted meat-packing plant, [and] we were able to go out and meet the people. It's not like it looks like on television - even just the diversity of the area. Where I was living, even though it was in Baghdad, it is actually very, very rural. We had to move our strykers to let herds of sheep go by. Then you go maybe 15 kilometers, or even 5 kilometers to the west...
