...project. If the species is declared threatened, FWS will have responsibilities under the Endangered Species Act to protect the bears from their main danger - in this case, climate change. That means the government could be challenged legally for anything that increases carbon dioxide emissions - like a new coal power plant - on the grounds that further climate change would further endanger the polar bear. "It would be the first time that the Bush Administration would recognize that global warming had a significant and specific impact on a living being," says Eben Burnham-Snyder, a spokesperson for Markey. "This could have...
...fastest way to start a fistfight among environmentalists is to bring up the topic of biofuels - plant-based liquid fuels like ethanol that could potentially take the place of petroleum. Biofuel revolutionaries - like Silicon Valley venture capitalist Vinod Khosla - see plant power as a way to break America's dependence on foreign oil, and produce auto fuel that doesn't kill the climate. Opponents dismiss biofuels - most of which are currently distilled from crops like corn and sugar cane - as a blind alley, one that drives up food prices without saving the earth...
...what if biofuels could be made without food crops, using an inedible plant grown on less than optimum farmland? That's exactly the thinking behind the push to develop cellulosic ethanol from the waste plant switchgrass, which grows throughout the Midwestern prairies, with little input from farmers. Instead of fuel from food, switchgrass cellulosic ethanol promises fuel from virtually nothing - and a new paper in the Proceedings of the National Academy of Sciences (PNAS) argues that it's worth making the switch...
...landfill gas plant will initially produce about 1 MW of power, starting in 2008, with a maximum capacity of some 10 MW - enough to deliver electricity to around 700 Bali households. Those numbers might seem small, and while the Suwung project is a nice start, that modest scale is part of the problem. CDM projects are one of the most promising ways to reduce greenhouse gas emissions in developing countries - all the more important, given that most of the increase in carbon dioxide in the near future will come from outside the developed world. But while funders are flocking...
...term certainty that they won't be undercut by old, dirty fuels dipping down to cheaper prices again. "That risk [of volatility] makes consumers and investors alike very reluctant to bank on high prices," says Greene. It doesn't make sense to spend hundreds of millions on an ethanol plant if the Saudis can undercut you by turning on the oil spigots...
