(02/28/2014) Massive offshore wind turbine arrays would reduce hurricane wind speeds and storm surge, reports a study published this week in Nature Climate Change. And while the size (tens of thousands of turbines) and cost (hundreds of billions of dollars) is difficult to imagine, the reduction in storm damage and value of electricity produced would effectively bring the price tag to zero according to the study authors.
Coal's future carbon costs may make it more expensive than wind energy
(11/15/2013) At first glance, a recent report from the U.S. White House on the social cost of carbon reads like a daunting economics exam. A small chart poses the first question about the price tag policymakers attach to future greenhouse gas emissions: Does each metric ton of carbon that billows into the air cost $11, $33 or $52? The answer is all of the above.
'Carbon bubble' could cause next global financial crisis
(04/22/2013) The world could be heading for a major economic crisis as stock markets inflate an investment bubble in fossil fuels to the tune of trillions of dollars, according to leading economists. "The financial crisis has shown what happens when risks accumulate unnoticed," said Lord (Nicholas) Stern, a professor at the London School of Economics. He said the risk was "very big indeed" and that almost all investors and regulators were failing to address it.
New wind power cheaper than coal or gas in Australia
(02/08/2013) Electricity supplied from a new wind farm is cheaper than that from a new gas or coal-fired power plant in Australia, reports a new analysis published by Bloomberg New Energy Finance.
Paradigm shift needed to avert global environmental collapse, according to author of new book The Blueprint: Averting Global Collapse
(01/10/2013) Global strategist, trained educator, and international lecturer Daniel Rirdan set out to create a plan addressing the future of our planet. His book The Blueprint: Averting Global Collapse, published this year, does just that. "It has been a sixty hour a week routine," Rirdan told mongabay.com in a recent interview. "Basically, I would wake up with the burden of the world on my shoulders and go to sleep with it. It went on like this for eighteen months." It becomes apparent when reading The Blueprint that it was indeed a monumental undertaking.
Google invests $200m in west Texas wind farm
(01/09/2013) Google has made another big renewable energy investment, putting $200 million into a Texas wind farm, said the Internet search giant in a post on its official blog.
Scientists: if we don't act now we're screwed
(06/07/2012) Scientists warn that the Earth may be reaching a planetary tipping point due to a unsustainable human pressures, while the UN releases a new report that finds global society has made significant progress on only four environmental issues out of ninety in the last twenty years. Climate change, overpopulation, overconsumption, and ecosystem destruction could lead to a tipping point that causes planetary collapse, according to a new paper in Nature by 22 scientists. The collapse may lead to a new planetary state that scientists say will be far harsher for human well-being, let alone survival.
Consumption, population, and declining Earth: wake-up call for Rio+20
(05/15/2012) Currently, human society is consuming natural resources as if there were one-and-a-half Earths, and not just a single blue planet, according to the most recent Living Planet Report released today. If governments and societies continue with 'business-as-usual' practices, we could be consuming three years of natural resources in 12 months by 2050. Already, this ecological debt is decimating wildlife populations worldwide, disproportionately hurting the world's poor and most vulnerable, threatening imperative resources like food and water, heating up the atmosphere, and risking global well-being.
For Earth Day, 17 celebrated scientists on how to make a better world
(04/22/2012) Seventeen top scientists and four acclaimed conservation organizations have called for radical action to create a better world for this and future generations. Compiled by 21 past winners of the prestigious Blue Planet Prize, a new paper recommends solutions for some of the world's most pressing problems including climate change, poverty, and mass extinction. The paper, entitled Environment and Development Challenges: The Imperative to Act, was recently presented at the UN Environment Program governing council meeting in Nairobi, Kenya.
Brazilian mining company connected to Belo Monte dam voted worst corporation
(01/31/2012) The world's second largest mining company, Vale, has been given the dubious honor of being voted the world's most awful corporation in terms of human rights abuses and environmental destruction by the Public Eye Awards. Vale received over 25,000 votes online, likely prompted in part by its stake in the hugely controversial Brazilian mega-dam, Belo Monte, which is being constructed on the Xingu River. An expert panel gave a second award to British bank Barclay's for speculation on food prices, which the experts stated was worsening hunger worldwide.
EU's biofuel push based on 'flawed' science
(10/10/2011) Europe's biofuel push could exacerbate climate change unless policies are in place to accounts for emissions from indirect land use change, warns a letter signed by more than 100 scientists and economists.
Could palm oil help save the Amazon?
(06/14/2011) For years now, environmentalists have become accustomed to associating palm oil with large-scale destruction of rainforests across Malaysia and Indonesia. Campaigners have linked palm oil-containing products like Girl Scout cookies and soap products to smoldering peatlands and dead orangutans. Now with Brazil announcing plans to dramatically scale-up palm oil production in the Amazon, could the same fate befall Earth's largest rainforest? With this potential there is a frenzy of activity in the Brazilian palm oil sector. Yet there is a conspicuous lack of hand wringing by environmentalists in the Amazon. The reason: done right, oil palm could emerge as a key component in the effort to save the Amazon rainforest. Responsible production there could even force changes in other parts of the world.
Sugar cane cools climate when it replaces cattle pasture
(04/17/2011) Converting cattle pasture and cropland in Brazil to sugar cane helps cool local climate reports research published in Nature Climate Change.
Indigenous leaders take fight over Amazon dams to Europe
(03/02/2011) Three indigenous Amazonian leaders spent this week touring Europe to raise awareness about the threat that a number of proposed monster dams pose to their people and the Amazon forest. Culminating in a press conference and protests in London, the international trip hopes to build pressure to stop three current hydroelectric projects, one in Peru, including six dams, and two in Brazil, the Madeira basin industrial complex and the massive Belo Monte dam. The indigenous leaders made the trip with the NGO Rainforest Foundation UK, including support from Amazon Watch, International Rivers, and Rainforest Concern.
Photo gallery: Borneo paradise saved from beachside coal plant
(02/22/2011) Last week the Malaysian government announced it had canceled a plan to build a coal-fired plant in the state of Sabah. The coal plant would have rested on a beach overlooking the Coral Triangle, one of the ocean's most biodiverse ecosystems, and 20 kilometers from Tabin Wildlife Reserve, a rainforest park home to endangered orangutans, Sumatran rhinos, Bornean elephants, and thousands of other species. The cancellation followed a long campaign by a group of environmental and human right organizations dubbed Green SURF (Sabah Unite to Re-power the Future), which argued that the coal plant would have imperiled ecosystems, ended artisanal fishing in the area, hurt tourism, and tarnished Sabah's reputation as a clean-green state.
Environmentalists and locals win fight against coal plant in Borneo
(02/16/2011) Environmentalists, scientists, and locals have won the battle against a controversial coal plant in the Malaysian state of Sabah in northern Borneo. The State and Federal government announced today that they would "pursue other alternative sources of energy, namely gas, to meet Sabah's power supply needs." Proposed for an undeveloped beach on the north-eastern coast of Borneo, critics said the coal plant would have threatened the Coral Triangle, one of the world's most biodiverse marine ecosystems, and Tabin Wildlife Reserve, home to Critically Endangered Sumatran rhinos and Bornean orangutans. Local fishermen feared that discharges from the plant would have imperiled their livelihood.
Is Obama's clean energy revolution possible?
(01/26/2011) Last night US President Barack Obama called for a massive green energy make-over of the world's largest economy. Describing the challenge as 'this generation's Sputnik moment' the US president set a goal of producing 80 percent of America's energy by clean sources by 2035. While this may sound improbable, two recent analyses back the president up, arguing that a global clean energy revolution is entirely possible within a few decades using contemporary technology and without breaking the bank. "Based on our findings, there are no technological or economic barriers to converting the entire world to clean, renewable energy sources," Mark Z. Jacobson, a professor of civil and environmental engineering at Stanford said in a press release. "It is a question of whether we have the societal and political will."
Prairie grass-based biofuels could meet half current fuel demand without affecting forests, food
(01/26/2011) Biofuels could meet up to half the world's current fuel consumption without affecting food production or forests, argues a study published last month in the journal Environmental Science and Technology.
Indonesia to open protected forests to geothermal power
(01/14/2011) The Indonesian government will soon issue a decree allowing geothermal mining in protected forests, reports The Jakarta Post.
Majority of Americans confused on climate change basics
(10/17/2010) Most Americans don't understand the basics of climate change, according to a new poll by researchers with Yale. The poll found that over half of Americans deserve an 'F' on basic understanding of climate science and climate change, while only 1% would receive an 'A'.
Humanity consuming the Earth: by 2030 we'll need two planets
(10/13/2010) Too many people consuming too much is depleting the world's natural resources faster than they are replenished, imperiling not only the world's species but risking the well-being of human societies, according to a new massive study by the World Wildlife Fund (WWF), entitled the Living Planet Report. The report finds that humanity is currently consuming the equivalent of 1.5 planet Earths every year for its activities. This overconsumption has caused biodiversity—in this case, representative populations of vertebrate animals—to fall by 30 percent worldwide since 1970. The situation is more dire in tropical regions where terrestrial species' populations have fallen by 60 percent and freshwater species by 70 percent.
Farms in the sky, an interview with Dickson Despommier
(10/12/2010) To solve today's environmental crises—climate change, deforestation, mass extinction, and marine degradation—while feeding a growing population (on its way to 9 billion) will require not only thinking outside the box, but a "new box altogether" according to Dr. Dickson Despommier, author of the new book, The Vertical Farm. Exciting policy-makers and environmentalists, Despommier's bold idea for skyscrapers devoted to agriculture is certainly thinking outside the box.
Citizens of 188 countries challenge leaders on climate change
(10/11/2010) As world leaders continue to fumble a coherent, rapid, and comprehensive response to climate change, citizens from around the world yesterday sent a message to inert politicians by participating in over 7,300 events against climate change, according to 350.org, the head organizer of the day dubbed the 'Global Work Party'. "The fossil fuel industry may have thought that the collapse of the Copenhagen talks and its victory in the U.S. Congress were the final word—that people would give up in discouragement," said, Bill McKibben, founder of 350.org, so-called because 350 parts per millions (ppm) is the 'safe' amount of carbon in the atmosphere according to many scientists. Currently the concentration is around 390 ppm.
EU's biofuels target driving land grabs in Africa, says group
(08/30/2010) The European Union's renewable fuels target is driving land grabs in Africa that threaten the environment and local communities, claims a new report from Friends of the Earth (FOE).
Environmental assessment for Borneo coal plant riddled with errors
(08/03/2010) The Detailed Environmental Impact Assessment (DEIA) for a proposed coal plant in Sabah is full of holes, according to activists with the organization Green SURF (Sabah Unite to Re-Power the Future), which opposes the plant. The official environmental report from Lahad Datu Energy lists species not endemic to Borneo, mistakes the nearest ecosystem to the coal plant, and confuses indigenous groups. Even more seriously, the DEIA leaves out information on the coal plant's specifics and possible 'green' alternatives.
Visiting the Gulf: how wildlife and people are faring in America's worst environmental disaster, an interview with Jennifer Jacquet
(07/29/2010) "President Obama called it 'the worst environmental disaster America has ever faced.' So I thought I should face it and head to the Gulf"—these are the opening words on the popular blog Guilty Planet as the author, marine biologist Jennifer Jacquet, embarked on a ten day trip to Louisiana. As a scientist, Jacquet was, of course, interested in the impact of the some four million barrels of oil on the Gulf's already depleted ecosystem, however she was as equally keen to see how Louisianans were coping with the fossil fuel-disaster that devastated their most vital natural resource just four years after Hurricane Katrina.
A total ban on primary forest logging needed to save the world, an interview with activist Glen Barry
(06/02/2010) Radical, controversial, ahead-of-his-time, brilliant, or extremist: call Dr. Glen Barry, the head of Ecological Internet, what you will, but there is no question that his environmental advocacy group has achieved major successes in the past years, even if many of these are below the radar of big conservation groups and mainstream media. "We tend to be a little different than many organizations in that we do take a deep ecology, or biocentric approach," Barry says of the organization he heads. "[Ecological Internet] is very, very concerned about the state of the planet. It is my analysis that we have passed the carrying capacity of the Earth, that in several matters we have crossed different ecosystem tipping points or are near doing so. And we really act with more urgency, and more ecological science, than I think the average campaign organization."
U.S. approves first offshore wind farm
(04/28/2010) The Obama Administration has approved the nation's first offshore wind farm after more than eight years of legal challenges, reports the Associated Press.
What happened to China?: the nation's environmental woes and its future
(04/01/2010) China has long been an example of what not to do to achieve environmentally sustainability. Ranking 133rd out of 146 countries in 2005 for environmental performance, China faces major environmental problems including severe air and water pollution, deforestation, water-issues, desertification, extinction, and overpopulation. A new article in Science discusses the complex issues that have led to China's environmental woes, and where the nation can go to from here.
Analysis shows Borneo can say 'no' to coal power
(03/17/2010) Plans for a coal power plant in the Malaysian state of Sabah in northern Borneo have run into stiff opposition. Environmentalists say the coal plant could damage extensive coral reef systems, pollute water supplies, open rainforests to mining, and contribute to global climate change, undercutting Sabah's image as a 'green' destination. The federal government contends that the coal plant is necessary to fix Sabah's energy problems. However, a recent energy audit by the Renewable and Appropriate Energy Laboratory (RAEL) at the University of California Berkeley shows that pollution-intensive coal doesn't have to be in Sabah's future.
Could special bonds fund the green revolution and stabilize the climate?
(02/02/2010) There is no question that governments around the world are moving slowly and sluggishly to combat climate change, especially when placed against the measures recommended by climate scientists. Only a handful of nations have actually cut overall greenhouse gas emissions, and the past couple decades have seen emissions rise rapidly worldwide as nations like India and China industrialize while Brazil and Indonesia continue massive deforestation. Global temperatures are rising in concert (though with natural fluctuations): the past decade is the warmest on record. After the failure of Copenhagen this past December to produce an ambitious and binding treaty, many are wondering if the world will ever address the threat of climate change or if future generations are set to live in a world far different—and more volatile—than the one we currently enjoy.
UK failing to meet biofuel sustainability standard
(02/01/2010) Only 4 percent of biofuel imported for use in the UK meets the environmental sustainability standard set by the Renewable Transport Fuel Obligation (RFTO), reports a new assessment from the Renewable Fuels Agency.
Could space technology save our planet?
(01/06/2010) A new book, Paradise Regained: the Regreening of Earth argues that the solutions to the world’s current environmental crises—including climate change—could be lying far beyond our planet.
James Hansen says Copenhagen approach "fundamentally wrong" would be better to "reassess"
(12/03/2009) James Hansen, one of the world's foremost climatologists, told the Guardian today that he believes the Copenhagen talks are flawed to the point where failure of the talks may be the best way forward. "The approach that is being talked about is so fundamentally wrong that it would be better to reassess," Hansen said.
Blackout in Brazil: Hydropower and Our Climate Conundrum
(11/19/2009) It’s everyone’s worst nightmare: being caught in an underground subway in the midst of a power outage. Yet, that is exactly what happened recently when Brazilian commuters in the city of São Paulo were trapped inside trains and literally had to be pulled out of subway cars. In addition to sparking problems in public transport, the blackout or apagão led to hospital emergencies and the shutting down of several airports. In all the power outage darkened approximately half of the South American nation, affecting sixty million people.
Fossil fuel subsidies "bringing us closer to irreversible climate change"
(11/06/2009) The Green Economy Coalition is urging G20 finance ministers to rapidly put an end to fossil fuel subsidies. In a letter to the ministers the coalition argues that these subsidies are contributing directly to climate change and making it difficult for the world to transition to a greener economy.
The Yangtze River may have lost another inhabitant: the Chinese paddlefish
(10/22/2009) In December of 2006 it was announced that the Yangtze River dolphin, commonly known as the baiji, had succumbed to extinction. The dolphin had survived on earth for 20 million years, but the species couldn't survive the combined onslaught of pollution, habitat loss, boat traffic, entanglement in fishing hooks, death from illegal electric fishing, and the construction of several massive dams. Now, another flagship species of the Yangtze River appears to have vanished.
US subsidies of oil and coal more than double the subsidies of renewable energy
(09/21/2009) During the fiscal years of 2002-2008 the United States handed out subsidies to fossil fuel industries to a tune of 72 billion dollars, while renewable energy subsidies, during the same period, reached 29 billion dollars.
Power, profit, and pollution: dams and the uncertain future of Sarawak
(09/03/2009) Sarawak, land of mystery, legend, and remote upriver tribes. Paradise of lush rainforest and colossal bat-filled caves. Home to unique and bizarre wildlife including flying lemurs, bearcats, orang-utans and rat-eating plants. Center of heavy industry and powerhouse of Southeast Asia. Come again? This jarring image could be the future of Sarawak, a Malaysian state on the island of Borneo, should government plans for a complex of massive hydroelectric dams comes to fruition. The plan, which calls for a network of 12 hydroelectric dams to be built across Sarawak's rainforests by 2020, is proceeding despite strong opposition from Sarawak's citizens, environmental groups, and indigenous human rights organizations. By 2037, as many as 51 dams could be constructed.
Solar powered conservation
(08/25/2009) Electricity can be a difficult commodity to procure in the remote areas where conservationists often work. Typically field researchers and wildlife rangers rely on gas-powered generators, which require imported fuel, often produce noxious fumes and disruptive noise, and can be costly to maintain. A better option, especially in sun-drenched parts of the world, is solar. Clean and silent, with no need for supplemental fuel, solar seems like an ideal fit for conservation work except for one major drawback: cost. But Stephen Gold – Solar and Technology Manager for Wildlife Conservation Network has been working to overcome that obstacle.
Environmental disappointments under Obama
(08/24/2009) While the President has been bogged down for the last couple months in an increasingly histrionic health-care debate-which has devolved so far into ridiculousness that one doesn't know whether to laugh or cry-environmental decisions, mostly from the President's appointees have still been coming fast and furious. However, while the administration started out pouring sunshine on the environment (after years of obfuscated drudgery under the Bush administration), they soon began to move away from truly progressive decisions on the environment and into the recognizable territory of playing it safe-and sometimes even stupid.
Little hydroelectric dams become all the rage, but do they harm the environment?
(08/23/2009) Looking for a way to create energy that doesn’t contribute to climate change and avoid the usual opposition that comes with building large hydroelectric dams, many energy companies are now pursuing constructing small hydroelectric dams in the wilderness, reports the Wall Street Journal.
Will hydrocarbon biofuels replace gasoline and ethanol?
(08/13/2009) In a Perspectives piece in Science, John R. Regalbuto argues that the world will soon see a revolution in biofuels, but not those made from corn. Instead Regalbuto, program director of Catalysis and Biocatalysis at the National Science Foundation, says that the future of biofuels is in substances that can be converted into hydrocarbons, such as switch grass, woody biomass, corn stover, and even algae.

(12/15/2008) Expansion of corn acreage to meet ethanol targets is reducing the ability of beneficial insects to control pests, a loss valued at $58 million in the four states studied (Michigan, Iowa, Minnesota and Wisconsin), report researchers writing in the journal Proceedings of the National Academy of Sciences.
Africa eyes geothermal power
(12/15/2008) Geothermal — the tapping of steam from hot underground rocks — could provide a source of clean, renewable energy in parts of Africa where electricity is currently limited, according to an assessment by the United Nations Environment Program (UNEP) and the Global Environment Facility (GEF).
Living up to the Pope's words: the Vatican turns to solar power
(11/28/2008) In his three years since being inaugurated, Pope Benedict XVI has made the environment one of his central issues, proclaiming that "God entrusted man with the responsibility of creation". He has described the need to confront climate change as a “moral obligation” and spoken eloquently on the destruction of arable soil, forests and marine life.
Limiting global warming to 2-degree rise will require $180/t carbon price says energy think tank
(11/13/2008) In a report released Wednesday the International Energy Agency warned that a business-as-usual approach to energy use would result in a 6°-degree rise in temperatures putting hundreds of millions at risk from reduced water supplies and diminished agricultural production. But the agency said that limiting temperature rise to 2-3°-rise by the end of the century would be "possible, but very hard."
Biodiversity of rainforests should not be compared with oil palm plantations says palm oil council chief
(11/11/2008) Scientists should compare the biodiversity oil palm plantations to other industrial monocultures, not the rainforests they replace, said Dr. Yusof Basiron, CEO of the Malaysian Palm Oil Council (MPOC), in a post on his blog. Basiron's comments are noteworthy because until now he has maintained that oil palm plantations are "planted forests" rather than an industrial crop.
First RSPO-certified ("eco-friendly") palm oil shipment to arrive in Europe
(11/10/2008) The first shipment of palm oil certified under the Roundtable on Sustainable Palm Oil (RSPO) is expected to arrive in Europe Tuesday, but an environmental group is already criticizing the initiative's credentials.

Rainforest fungus generates biodiesel, may drive energy of the future
(11/04/2008) A fungus recently discovered in the Patagonian rainforest has shocked biologists and environmentalists: the fungus produces gas almost identical to diesel. In a paper announcing the discovery in Microbiology, scientists state that they believe the fungus, called Gliocladium roseum, could become an incredibly efficient green energy source.
Green New Deal will spark global economy, create jobs
(10/22/2008) A "Global Green New Deal" that focuses the world economy "towards investments in clean technologies and 'natural' infrastructure such as forests and soils is the best bet for real growth, combating climate change and triggering an employment boom," according to a new initiative led by the United Nations Environment Programme (UNEP).
Challenges of starting a green business
(10/20/2008) While green design offers the potential to greatly improve the sustainability of new goods and services without sacrificing performance, developing and bringing such products to market is a challenge, said a panel of innovators from companies using nature as inspiration for new technologies. Speaking at the 2008 Bioneers conference in San Rafael, California, Stephen Dewar of WhalePower, Charles Hamilton of Novomer, and Jay Harman of PAX Scientific told biomimicry expert Jane Benyus that radically new approaches to solving design and engineering problems is often met with skepticism from the existing market.
Financial crisis could pave way for greener economy inspired by nature
(10/20/2008) Biomimicry — the use of nature to inspire design — could serve as a model for a greener economy that rises out of the ashes of the financial crisis, said experts meeting at a sustainability conference in the San Francisco Bay Area. Speaking at the three-day Bioneers conference in San Rafael, Janine Benyus, a leading voice in the emerging field of biomimicry, said that nature offers lessons that can be applied to build better and more sustainable products and services as well as economic models.
U.S. needs environmental standards for biofuels
(10/02/2008) The U.S. lacks criteria to ensure that cellulosic ethanol production will not harm the environment, warn scientists writing in the journal Science. The researchers say that with proper safeguards, cellulosic ethanol can help the U.S. meet its energy needs sustainably.
U.S. Congress passes legislation to boost solar, wind, and geothermal energy

Europe cuts biofuel targets to 4% in 2015, 6% in 2020
(09/12/2008) The E.U. voted to relax biofuels targets following widespread criticism of their social, economic, and environmental impacts. Thursday the European Parliament's Industry and Energy Committee said it would push a plan calling for a 5 percent share of renewables in transport fuel by 2015 and a 10 percent target by 2020, a reduction from the 20 percent target set forth in March 2007. The plan effectively cuts targets for biofuels produced from conventional feedstocks to four percent in 2015 and six percent in 2020.
Biofuels 200 times more expensive than forest conservation for global warming mitigation
(08/27/2008) The British government should end subsidies for biofuels and instead use the funds to slow destruction of rainforests and tropical peatlands argues a new report issued by a U.K.-based think tank. The study, titled "The Root of the Matter" and published by Policy Exchange, says that "avoided deforestation" would be a more cost-effective way to address climate change, since land use change generates more emissions than the entire global transport sector and offers ancillary benefits including important ecosystem services.
How do wind turbines kill bats?
(08/25/2008) Numerous studies have shown that migratory bats are undergoing large fatalities due to wind turbines. Far more bats die due to wind turbines than birds, though they generally receive less attention. Now, researchers writing in Current Biology believe they know why bats are more susceptible to wind turbine fatalities.

Facing criticism, biofuels industry forms new lobby group to influence lawmakers
(07/25/2008) Under attack by politicians, aid groups, and environmentalists for driving up food prices and fueling destruction of ecologically sensitive habitats, some of the world's largest agroindustrial firms have formed a lobby group to influence consumers and lawmakers to support continued subsidies for biofuel production, reports Reuters.
Biofuels can reduce emissions, but not when grown in place of rainforests
(07/22/2008) Biofuels meant to help alleviate greenhouse gas emissions may be in fact contributing to climate change when grown on converted tropical forest lands, warns a comprehensive study published earlier this month in the journal Environmental Research Letters. Analyzing the carbon debt for biofuel crops grown in ecosystems around the world, Holly Gibbs and colleagues report that "while expansion of biofuels into productive tropical ecosystems will always lead to net carbon emissions for decades to centuries... [expansion] into degraded or already cultivated land will provide almost immediate carbon savings." The results suggest that under the right conditions, biofuels could be part of the effort to reduce humanity's carbon footprint.
Gore launches second campaign... for Earth
(07/17/2008) In a speech Thursday, Al Gore challenged the U.S. to generate 100 percent of its electricity from zero carbon emission sources within 10 years. Speaking at Washington's Constitution Hall, Gore said America's security, environmental and economic crises are all related, and that measures to rein in greenhouse gas emissions will make the U.S. stronger, safer, and cleaner. "The survival of the United States of America as we know it is at risk," Gore said. "I don't remember a time in our country when so many things seemed to be going so wrong simultaneously."
Breakthrough in solar energy: ten times more effective solar power may be available in three years
(07/10/2008) The breakthrough scientists have been waiting for to make solar power cheaper, more efficient--and therefore a more effective replacement for traditional energy sources--has been made by a group of MIT researchers.
Oceans hold vast potential for wind power
(07/09/2008) The North Pacific, Tasmania, New Zealand, Tierra del Fuego in South America, and the mid-latitudes of the Atlantic and Pacific oceans are potential locations for wind power generation, according to new satellite data from NASA.
Britain urges 'cautious approach' on biofuels
(07/07/2008) Britain and the E.U. should exercise caution in pushing for wider use of biofuels, warns a new study commissioned by the U.K. government.

Cellulosic biofuels may be viable alternative to gas within 5 years
(06/02/2008) A new institute in the San Francisco Bay Area is seeking to make cellulosic biofuel an economically viable alternative to corn ethanol and gasoline within the next five years. The Joint BioEnergy Institute (JBEI), a partnership between three national laboratories and three Bay Area universities, was formed in June 2007 after the U.S. Department of Energy awarded the institute a $125 million grant to develop better methods for making liquid biofuels from the natural cellulose in trees and grasses. JBEI researchers expect cellulosic biofuels to yield more energy, produce less greenhouse gases, and have less impact on the environment than other alternatives to gasoline, such as corn ethanol.

Carbon tax would make China greener and reduce warming risks
(02/07/2008) Driven by booming economic growth and rapid urbanization, China's carbon dioxide emissions are surging. At the same time, forecasts suggest climate change will have an immense impact on the country, with rising sea levels projected to swamp key industrial areas and diminished rainfall reducing agricultural output. Given this outlook, a new policy paper published in Science argues that China will need to embark on a cleaner path to growth, one that is less dependent on coal. The authors say that international assistance in the form of carbon funds could help persuade Chinese leadership to move towards more environmentally-friendly energy technologies.
Biofuels are worsening global warming
(02/07/2008) Converting native ecosystems for production of biofuel feed stocks is worsening the greenhouse gas emissions they are intended to mitigate, reports a pair of studies published in the journal Science.

Wind power takes a toll on migratory bats
(09/12/2007) The danger of wind turbines to birds has long been known and well documented. Most recently several studies and articles have attempted to place the level of bird casualties in perspective: "More birds killed by cats than wind turbines". But lesser known--and lesser studied--is the effect wind turbines have on bat populations. Collisions between groups of bats and wind turbines have been observed at numerous turbines in America, Australia, and Europe. While these fatalities, sometimes killing hundreds of bats, have been seen for years, their cause remains unknown.

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.
