U.S. biofuels policy drives deforestation in Indonesia, the Amazon
(01/17/2008) U.S. incentives for biofuel production are promoting deforestation in southeast Asia and the Amazon by driving up crop prices and displacing energy feedstock production, say researchers.
Cellulosic ethanol production could fight Gulf Dead Zone, help fisheries
(01/16/2008) Feedstocks for cellulosic ethanol production could help fight the massive "dead zone" that forms each year in the Gulf of Mexico as a result of current farming practices, says a University of Alabama in Huntsville biologist.
Indonesia seeks to cut fuel subsidies via biofuels
(01/15/2008) Biofuels will make up 10 percent of Indonesia's fuel transport consumption by 2010 under a plan announced Monday by a senior government official, according to Reuters. The initiative could ease the economic impact of fuel subsidies - currently some of the highest in the world - in Indonesia, while boosting demand for locally produced bioenergy crops including palm oil, jatropha, sugar cane and cassava.
E.U. may ban palm oil biodiesel
(01/15/2008) The E.U. may ban imports of certain biofuel feedstocks that damage the environment, reports The New York Times. Environmentalists say some biofuels like palm oil are driving the destruction of biologically-rich rainforests and may produce more emissions than conventional fossil fuels.
Switchgrass a better biofuel source than corn
(01/07/2008) Switchgrass yields more than 540 percent more energy than the energy needed to produce and convert it to ethanol, making the grassy weed a far superior source for biofuels than corn ethanol, reports a study published in Proceedings of the National Academy of Sciences (PNAS).
Leading biofuels wreak environmental havoc
(01/03/2008) Biofuels made from world's dominant energy crops -- including corn, soy, and oil palm -- may have worse environment impacts than conventional fossil fuels, reports a study published in the journal Science.
U.S. corn subsidies drive Amazon destruction
(12/13/2007) U.S. corn subsidies for ethanol production are contributing to deforestation of the Amazon rainforest, reports a tropical forest scientist writing in this week's issue of the journal Science.
Termites may produce cleaner biofuels
(11/23/2007) Termites may be the key to greener, more effective biofuels, report scientists writing in the November 22 edition of the journal Nature.
Is the oil-palm industry using global warming to mislead the public?
(11/23/2007) Members of the Indonesian Palm Oil Commission are distributing materials that misrepresent the carbon balance of oil-palm plantations, according to accounts from people who have seen presentations by commission members. These officials are apparently arguing that oil-palm plantations store and sequester many times the amount of CO2 as natural forests, and therefore that converting forests for plantations is the best way to fight climate change. In making such claims, these Indonesian representatives evidently are ignoring data that show the opposite, putting the credibility of the oil-palm industry at risk, and undermining efforts to slow deforestation and rein in greenhouse gas emissions.
Oil palm does not store more carbon than forests
(11/08/2007) Officials from the Indonesian ministry of agriculture and the palm oil industry are distributing materials that misrepresent the carbon balance oil palm plantations, according to accounts from people who have seen presentations by members of the Indonesian Palm Oil Commission. Ministry of agricultural officials are apparently arguing that oil palm plantations store and sequester many times the amount of CO2 as natural forests and therefore converting forests for plantations is the best way to fight climate change. In making such claims, these Indonesian officials are ignoring data that show the opposite, putting the credibility of the oil palm industry at risk, and undermining efforts to slow deforestation and reign in greenhouse gas emissions.
Guidelines to ensure biofuels production won't hurt the environment
(08/30/2007) Environmentalists have long seen biofuels as a means to improve the sustainability of transportation and energy use since they are a renewable source of energy that can be replenished on an ongoing basis. Further, because biofuels are generally derived from plants, which absorb carbon from the atmosphere as they grow, biofuel production offers the potential to help offset carbon dioxide emissions and mitigate climate change. Nonetheless, in recent years, there has been considerable backlash against biofuels, which are increasingly viewed as a threat to the environment. Green groups now point to large-scale land conversion for energy crops, higher food prices, and a spate to studies that suggest net emissions from corn ethanol are little better than those from fossil fuels, to caution that biofuels can cause more problems than they address.
With Corn ethanol more costly than oil, is Jatropha a better biofuel?
(08/24/2007) Jatropha may be a more economic biofuel than corn-based ethanol, reported the The Wall Street Journal on Friday, citing research from Goldman Sachs.
Monkey mothers use "baby talk" too
(08/24/2007) Female rhesus monkeys use special vocalizations to communicate with infants much like human mothers use "baby talk" or "motherese" reports a new study by researchers at the University of Chicago.
Biofuels driving destruction of Brazilian cerrado
(08/21/2007) The cerrado, wooded grassland in Brazil that once covered an area half the size of Europe, is fast being transformed into croplands to meet rising demand for soybeans, sugarcane, and cattle. The cerrado is now disappearing more than twice as the rate as the neighboring Amazon rainforest, according to a Brazilian expert on the savanna ecosystem.
conservation more effective than biofuels for fighting global warming
(08/15/2007) Conserving forests and grasslands may be a more effective land-use strategy for fighting climate change than growing biofuel crops argues a new paper published in the journal Science. Comparing emissions from various fuel crops versus carbon storage in natural ecosystems, Renton Righelato and Dominick Spracklen write that "forestation of an equivalent area of land would sequester two to nine times more carbon over a 30-year period than the emissions avoided by the use of the biofuel."
Economics of next generation biofuels
(08/08/2007) 'Second generation' biorefineries -- those making biofuel from lignocellulosic feedstocks like straw, grasses and wood -- have long been touted as the successor to today's grain ethanol plants, but until now the technology has been considered too expensive to compete. However, recent increases in grain prices mean that production costs are now similar for grain ethanol and second generation biofuels, according to a paper published in the first edition of Biofuels, Bioproducts & Biorefining.
Corn ethanol is not the solution to energy independence
(07/18/2007) A new report claims that corn ethanol will not significantly offset U.S. fossil fuel consumption without "unacceptable" environmental and economic consequences.
US says Brazilian ethanol doesn't increase food prices, destroy Amazon rainforest
(07/13/2007) Brazil's surging ethanol production does not put the Amazon rainforest at risk and is not fueling higher food prices, claimed a U.S. energy official visiting Brazil.
Miscanthus bests switchgrass as biofuel source
(07/11/2007) In a side-by-side comparison, miscanthus (Miscanthus x giganteus) grass has been shown to be a more productive bioenergy source than switchgrass (Panicum virgatum), according to research presented at the annual meeting of the American Society of Plant Biologists in Chicago.
$100 billion invested in renewable energy in 2006
(06/20/2007) $100 billion poured into renewable energy and energy efficiency in 2006, a 25 percent jump from 2005, reports a new analysis by the UN Environment Programme (UNEP).
Globalization could save the Amazon rainforest
(06/03/2007) The Amazon basin is home to the world's largest rainforest, an ecosystem that supports perhaps 30 percent of the world's terrestrial species, stores vast amounts of carbon, and exerts considerable influence on global weather patterns and climate. Few would dispute that it is one of the planet's most important landscapes. Despite its scale, the Amazon is also one of the fastest changing ecosystems, largely as a result of human activities, including deforestation, forest fires, and, increasingly, climate change. Few people understand these impacts better than Dr. Daniel Nepstad, one of the world's foremost experts on the Amazon rainforest. Now head of the Woods Hole Research Center's Amazon program in Belem, Brazil, Nepstad has spent more than 23 years in the Amazon, studying subjects ranging from forest fires and forest management policy to sustainable development. Nepstad says the Amazon is presently at a point unlike any he's ever seen, one where there are unparalleled risks and opportunities. While he's hopeful about some of the trends, he knows the Amazon faces difficult and immediate challenges.
High corn price mean pigs eat candy bars, french fries
(05/20/2007) Near record high prices for corn mean that farmers are feeding their pigs people food according to an article in The Wall Street Journal.
U.S. ethanol may drive Amazon deforestation
(05/17/2007) Ethanol production in the United States may be contributing to deforestation in the Brazilian rainforest said a leading expert on the Amazon. Dr. Daniel Nepstad of the Woods Hole Research Center said the growing demand for corn ethanol means that more corn and less soy is being planted in the United States. Brazil, the world's largest producer of soybeans, is more than making up for shortfall, by clearing new land for soy cultivation. While only a fraction of this cultivation currently occurs in the Amazon rainforest, production in neighboring areas like the cerrado grassland helps drive deforestation by displacing small farmers and cattle producers, who then clear rainforest land for subsistence agriculture and pasture.
Biofuels displace indigenous people
(05/15/2007) Indigenous people are being pushed off their lands to make way for an expansion of biofuel crops around the world, threatening to destroy their cultures by forcing them into big cities, the head of a U.N. panel said Monday.
UN warns on dangers of bioenergy
(05/09/2007) Biofuels offer "an extraordinary opportunity" to reduce greenhouse gas emissions but could make "substantial demands on the world's land and water resources at a time when demand for both food and forest products is also rising rapidly," said the U.N. in its first assessment on the growing bioenergy industry.
Ethanol may be greener but have higher health cost
(04/18/2007) Widespread burning of ethanol as fuel may increase the number of respiratory-related deaths and hospitalizations relative to gasoline, according to a new study by Stanford University atmospheric scientist Mark Z. Jacobson. The report comes as mounting environmental concerns cloud the benefits of using ethanol as a green alternative to fossil fuels.
Biofuels demand will increase, not decrease, world food supplies
(03/27/2007) As concerns mount over fuel-versus-food competition for crops, a Michigan State University ethanol expert says that cellulosic ethanol could render the debate moot. Bruce Dale, an MSU chemical engineering and materials science professor, notes that ethanol can be made from cellulosic materials, like farm waste, instead of corn grain.
New green biofuels process could meet all U.S. transportation needs
(03/14/2007) Purdue University chemical engineers have proposed a new environmentally friendly process for producing liquid fuels from plant matter - or biomass - potentially available from agricultural and forest waste, providing all of the fuel needed for "the entire U.S. transportation sector."
Ethanol always not as green as some believe
(02/16/2007) Ethanol is generally not as green as some people believe says Bruce Dale, Michigan State University professor of chemical engineering and materials science. Speaking at the American Association for the Advancement of Science annual meeting in San Francisco, Dale says that while corn ethanol produces less greenhouse gases than gasoline, it can cause other detrimental environmental effects if not carefully managed.
Weedy grass could free U.S. of foreign oil dependence says biologist
(02/16/2007) A weedy grass may hold the key to domestic energy security and mitigating emissions of greenhouse gasese, said a Stanford University plant biologist speaking Friday at the annual meeting of the American Association for the Advancement of Science in San Francisco.
Biofuels, logging may spur deforestation in Guyana
(02/15/2007) Growing timber exports and rising interest in biofuels are raising concerns that deforestation could accelerate in the South American country of Guyana. Guyana is a small, lightly populated country on the north coast of South America. About three-quarters of Guyana is forested, roughly 60 percent of which is classified as primary forest. Guyana's forests are highly diverse: the country has some 1,263 known species of amphibians, birds, mammals, and reptiles, and 6,409 species of plants.
President Museveni again moves against Uganda's forests
(12/12/2006) Ugandan president Yoweri Museveni has again taken action against rainforest conservation in Uganda, moving to hand a protected forest reserve over to private agricultural interests intent on clearing trees, according to a report from Reuters.
Switchgrass-based ethanol could cost $1 per gallon, reduce foreign oil dependence
(12/05/2006) Genetic engineering of switchgrass, a native prairie plant, could reduce the price of ethanol to $1 per gallon according to a plant geneticist at the University of Rhode Island.
Cellulosic ethanol fuels environmental concerns
(08/06/2006) In recent months, high fuel prices and national security concerns have sparked interest in biofuels. Cellulosic ethanol, which can be derived from virtually any plant matter including farm waste, looks particularly promising. The U.S. Department of Energy projects that cellulosic conversion technology could reduce the cost of producing ethanol by as much as 60 cents per gallon by 2015. Green groups see cellulosic ethanol as a carbon neutral energy source that could be used to fight the build up of atmospheric carbon dioxide responsible for global warming.
Corn waste potentially useful for more than ethanol
(07/19/2006) After the corn harvest, whether for cattle feed or corn on the cob, farmers usually leave the stalks and stems in the field, but now, a team of Penn State researchers think corn stover can be used not only to manufacture ethanol, but to generate electricity directly.
Soybean biodiesel has higher net energy benefit than corn ethanol
(07/11/2006) The first comprehensive analysis of the full life cycles of soybean biodiesel and corn grain ethanol shows that biodiesel has much less of an impact on the environment and a much higher net energy benefit than corn ethanol, but that neither can do much to meet U.S. energy demand.
High oil prices fuel bioenergy push
(05/09/2006) High oil prices and growing concerns over climate change are driving investment and innovation in the biofuels sector as countries and industry increasingly look towards renewable bioenergy to replace fossil fuels. Bill Gates, the world's richest man, has recently invested $84 million in an American ethanol company while global energy gluttons ranging from the United States to China are setting long-term targets for the switch to such fuels which potentially offer a secure domestic source of renewable energy and fewer environmental headaches. Biofuels are fuels that are derived from biomass, including recently living organisms like plants or their metabolic byproducts like cow manure. Unlike fossil fuels -- like coal, petroleum, and natural gas, which are finite resources -- biofuels are a renewable source of energy that can be replenished on an ongoing basis. In general, biofuels are biodegradable and, when burned, have fewer emissions than traditional hydrocarbon-based fuels. Typically, biofuels are blended with traditional petroleum-based fuels, though it is possible to run existing diesel, engines purely on biodiesel, something which holds a great deal of promise as an alternative energy source to replace fossil fuels. Further, because biofuels are generally derived from plants which absorb carbon from the atmosphere as they grow, biofuel production offers the potential to help offset carbon dioxide emissions and mitigate climate change.
Scientists closer to understanding key to cellulosic biofuels
(04/20/2006) Cellulose -- a fibrous molecule found in all plants -- is the most abundant biological material on Earth. It is also a favored target of renewable, plant-based biofuels research. Despite overwhelming interest, scientists know relatively little about how plant cells synthesize individual cellulose fibers.
Biofuels can replace about 30 percent of fuel needs
(02/01/2006) With world oil demand growing, supplies dwindling and the potential for weather- and conflict-related supply interruptions, other types of fuels and technologies are needed to help pick up the slack.
Ethanol more energy-efficient than oil, finds study
(01/26/2006) Using ethanol -- alcohol produced from corn or other plants -- instead of gasoline is more energy-efficient that oil say researchers at the University of California, Berkeley.
High oil prices make Asia pursue green energy
(09/09/2005) For energy-hungry Asian governments, the answer could literally be blowing in the wind. Across the region, renewable energy such as solar, wind and geothermal power is gaining ever greater credence as a way to curb the region's appetite for oil and cut runaway import bills.
