...Beagle 2 project to land a spacecraft on the surface of Mars. "People always say these big questions don't have anything to do with their day-to-day life," he says. "But we get all sorts of spin-offs from asking about the universe. The technologies generated include carbon fibers, new electronic systems and sophisticated radio technologies. And perhaps more than that, they offer dreams for young scientists. They provide the inspiration for a new generation of pioneers...
...hard to see how. Earlier studies exposed corn ethanol as a carbon catastrophe; the EPA had to use extremely generous assumptions to produce scenarios in which it's even remotely attractive as a fuel alternative. In any case, the heavily subsidized corn-ethanol industries won't really be penalized for promoting deforestation and accelerating global warming; Congress exempted its existing plants from any consequences in the 2007 law requiring the stress tests. At her May 5 news conference with Energy Secretary Steven Chu and Agriculture Secretary Tom Vilsack, Jackson suggested this was a good thing, because corn ethanol...
...Farm fuels can sound like the ultimate win-win situation, reducing our dependence on carbon-intense fossil fuels while boosting demand for American farm products. And they're "renewable," which has become a kind of synonym for green. But years ago, researchers began raising concerns about the direct emissions created by the heavy machinery and petroleum-based fertilizers it takes to grow corn and other biofuel feedstocks, the energy-intensive plants that convert the crops into fuel and the trucks that transport the fuel to market. A slew of studies have concluded that when you include all these life-cycle...
...land use: when an acre of land is used to grow fuel instead of food, an extra acre somewhere else is probably going to be converted into farmland to grow food. And that acre may well be an acre of wetland or forest that would otherwise store loads of carbon. So farm fuels become a lose-lose deal: exacerbating the deforestation that already creates one fifth of the world's carbon emissions, and driving up global food prices. (See pictures of the global food crisis...
...point to 68° and raising the summer cooling set-point to 75°, the FAS will reduce its multimillion-dollar heating and cooling budget by an estimated 3 percent annually. This change has the added benefit of reducing annual greenhouse gas emissions by 1,200 metric tons of carbon dioxide equivalent (MTCDE) annually. FAS will continue to pursue such energy conservation strategies. As part of this process, an audit of all FAS facilities is underway, with the goal of simultaneously reducing our energy expenditures and shrinking our carbon footprint...
