Could marine cloud machines cool the planet?
(11/26/2012) In 1990, British cloud physicist John Latham published a paper arguing he could cool global climate by brightening clouds over the ocean. Most colleagues ignored the paper, titled 'Control global warming?'—probably because this thing called global warming was not yet a hot topic. Now, more than two decades later, Latham continues to develop what has become one of the most promising and controversial ideas in climate control. 'Marine cloud brightening' might sound benign, but hairs rise when it’s called 'geoengineering.'
Will we need to pull carbon out of the atmosphere to save ourselves?
(10/17/2012) This year saw the Arctic sea ice extent fall to a new and shocking low, while the U.S. experienced it warmest month ever on record (July), beating even Dust Bowl temperatures. Meanwhile, a flood of new research has convincingly connected a rise in extreme weather events, especially droughts and heatwaves, to global climate change, and a recent report by the DARA Group and Climate Vulnerability Forum finds that climate change contributes to around 400,000 deaths a year and costs the world 1.6 percent of its GDP, or $1.2 trillion. All this and global temperatures have only risen about 0.8 degrees Celsius (1.44 degrees Fahrenheit) since the early Twentieth Century. Scientists predict that temperatures could rise between 1.1 degrees Celsius (2 degrees Fahrenheit) to a staggering 6.4 degrees Celsius (11.5 degrees Fahrenheit) by the end of the century.
Tigers vs. coal in India: when big energy meets vanishing cats
(08/01/2012) Burning coal fuels climate change, causes acid rain, and spreads toxic pollutants into the environment, but now a new Greenpeace report warns that coal may also imperil the world's biggest feline: the tiger. Home to world's largest population of tigers—in this case the Bengal subspecies (Panthera tigris tigris)—India is also the world's third largest coal producer. The country's rapacious pursuit of coal—it has nearly doubled production since 2007—has pushed the industry into tiger territory, threatening to destroy forests and fragment the tiger's already threatened population.
Solar cells cross new threshold
(03/08/2012) Imagine powering your cell phone by leaving it on the window sill. Sounds like science fiction? Actually, this might soon turn into reality. Scientists have been exploring the potential of solar energy for decades. One of the cheapest ways to turn solar energy into electricity is by creating solar cells from organic polymers, which are easily manipulated by scientists. However, such cells are not efficient at converting sunlight to electricity. But now, researchers at UCLA’s Department of Materials Science and Engineering have come up with a new type of solar cell that sets the record in changing sunlight into power.
Germany proves the promise of renewable energy: hits 20 percent renewables
(09/06/2011) As many people in the United States question whether renewable energy is a viable alternative to fossil fuels, Germany now derives 20.8 percent of its electricity from renewable sources—a 15 percent increase since 2000, reports Der Spiegel. In contrast, the United States generates only 10 percent of its electricity from renewable sources, 6 percent of which comes from hydroelectric power, which some environmentalists see as unacceptably damaging.
Clean energy investments rise 630% in 7 years
(03/29/2011) According to a report by the US Pew Environment Group global clean energy investments, which do not include nuclear power, jumped 630% since 2004. The report detailing 2010 clean energy investments found that China remains the global leader in clean energy, while the US fell from 2nd to 3rd. This is the second year in a row that the US fell: in 2009 it lost first place to China. In all $243 billion were invested in clean energy in 2010.
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."

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.
China leaves US (and Europe) in the dust on renewable energy
(02/01/2010) This year China has become the world's largest manufacturer of solar panels and wind turbines, doubling its wind capacity since 2005. The economically booming nation—and the world's most populous—has also invested heavily in nuclear power and the world's most efficient coal plants, according to the New York Times.
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.
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.

Balloon technology could cut cost of solar energy 90% by 2010
(02/21/2007) With high energy prices and mounting concerns over human-induced climate change, there is intense interest in renewable energy, especially solar, which produces no pollution and is readily available in the form of sunlight. In recent years, however, the solar energy market has been hampered by supply shortages of refined silicon, the critical resource needed for solar cell fabrication. Further, because solar installations traditionally require a large surface area to capture as much sunlight as possible, solar arrays often take up real estate, occupying land used agricultural production and other purposes. Without government subsidies, solar is not presently viable in many areas.
