How Biofuels Increase Carbon Emissions
Science Blog offers interesting criticism
of the use of biofuels by way of a report from the University of Minnesota and the Nature Conservancy that says use of biofuels can actually speed up global warming where natural ecosystems are converted to biofuel farmland. The existing flora, it turns out, is better at processing carbon dioxide in the atmosphere than the stock used for ethanol and biodiesel, worsening the climate change balance.
The article cites a classic example
in the Amazon rain forest, where farmers are being encouraged to clear cut existing rain forest and plant soybeans, the current system rewarding them for quantity of crop as opposed to carbon balance. Science Blog does go on to say, however, that there are a number of different locales and environments in which biofuel crops are an improvement or a "push" in terms of carbon emission offset over existing vegetation.
President Bush's Energy Budget Doesn't Go Far Enough
Joe Romm at Climate Progress takes President Bush to task
for offering stirring and positive energy rhetoric while attempting to slash Department of Energy funding for critical projects. Focusing on his recent State of the Union Address statements, Romm suggests that the President's calls for action on energy and climate questions was a rhetorical smokescreen, hiding a broad deemphasizing of the question and the defunding of a number of programs.
Providing a breakdown of the budget request
in the post, he endeavors to show that Bush is not at all serious about the energy issues facing the United States and is trying to sweep it under the rug in his last year in office. Programs such as water energy research (that is, hydroelectric, wave, and steam power) appear to face significant cuts, along with completely defunding the Renewable Energy Production Incentive. Several programs do get boosts, including more research money for carbon sequestration in coal-fired plants and $7.5 million for the Asia-Pacific Partnership.
Paris Looks to Make Sustainability Stylish
Last week EcoGeek took a look at Parisian construction project
that aims to blend the kind of art and style that the city is known for with a 21st century energy ethic. Brainchild of Vincent Callebaut, noted architect and designer, the building would sit astride a disused canal in the city's 19th district. Actually a pair of buildings, the structures would aim to provide their own energy while simultaneously, actively reducing smog in the city.
According to the post
, Callebaut hopes to achieve this with an external mix of photovoltaic solar cells and a structure faced with titanium dioxide that "reacts with organics and reduces airborne pollutants and contaminants when exposed to the UV radiation present in sunlight." Both structures would also feature copious greenery on their exterior surfaces, and the second of the pair, a helical tower, would have built-in turbines to harness the wind that sweeps down the canal.
Real Goods Seeks Wall Street Splash With IPO
Treehugger points out
that solar installer Real Goods has completed paperwork to make an initial public offering (IPO) on NASDAQ. The company, now oned by Gaiam, recently acquired two other installation companies as part of a move to market consolidation, and now seeks investment funding to expand further.
Real Goods' revenues, according to Treehugger
, were estimated at $32.7 million for 2007, with profits of nearly half a million, with the acquired companies' revenues and profits taken into account. Going public could vastly improve Real Goods' standing and better position them in what is sure to be a highly competitive solar energy market.
