How green is that biofuel: It depends where it came from ?
Cambridge,MA,USA -GreenBiz, by Jonathan Bardelline -May 12, 2011: ... Researchers at MIT looked at life cycle GHG emissions related to 14 conventional fuels and biofuels... Biofuels usually come out on top, but a few bring bigger footprints... Palm oil from forests or rainforests that were clear-cut, soy oil from former rainforests. Can cause up to 10 times more carbon emissions than jet fuels. Researchers say all fuels have range of possible life cycle emissions... But on low end, all other biofuels are lower than conventional fuels... Fuels from switchgrass, salicornia, and palm oil from land not converted have lowest carbon footprints of all. Coming nowhere near emissions of normal fuels... Others lower their footprints by creating byproducts that can be used elsewhere. When jatropha oil produced, remaining shells, husks, meal used as animal feed, fertilizer, or burned to produce energy... (Picture from roadtransport: Biodiesel pump)
* USA - Survey: Americans Tired of Gas Prices, Ready for Fuel Standards to Double
Detroit,MICH,USA -The Detroit Bureau, by Paul A. Eisenstein -May 17, 2011: -- Americans are weary of watching gas prices soar and want near doubling of automotive fuel standards from 2016 targets... Nearly two-thirds polled by Opinion Research Group favored raising CAFÉ standard to 60 mpg by 2025... Despite strong opposition from auto industry, the White House it's considering bump to 62 mpg... Alliance of Automobile Manufacturers asking EPA to wait until new studies have been completed Significant Points... Automotive executives have asserted going to 60 mpg or above could cost $5K or more per vehicle – and would likely require significant shift towards battery power... But what consumers also don’t expect is to have to keep paying more and more for fuel, said Mark Cooper of Consumer Federation of America, which commissioned survey... Both industry and government leaders have fiercely fought proposals that would allow hodgepodge of standards in individual state...
* Brazil - Ethanol bio-fuel Iveco Trakker tractor on a roll in
Ribeirão Preto,SP,Brazil -BigLorryBlog -May 17, 2011: -- Word reaches Biglorryblog that Iveco, Fiat Powertrain Industrial and Bosch presented this rather splendid Iveco Trakker Bi-Fuel Ethanol-Diesel vehicle at the recent Agrishow, in Ribeirão Preto, the largest agricultural fair in Brazil... Anyroadup this Trakker tractor is equipped with an FPT Industrial Cursor 9 (yes that's the bigger capacity version of the Cursor 8) engine which can run on an ethanol/diesel mixture with lower fuel costs when compared to a conventional diesel engine... Designed to be used by sugar-cane and ethanol producers on their specific agricultural and industrial operations, the vehicle has been using a 40-60% ethanol-diesel average fuel mix on early tests, which contributes to reduce fossil-fuel use and allows for an improved environmental proposition, since ethanol is a fully renewable fuel. The vehicle has been developed in Brazil with the institutional support of UNICA, the Brazilian association of sugar-cane producers under a program to promote "green policies" in the sugar and ethanol business...Labels: alternative fuels, biofuels
