The world's first floating wind turbine is to be towed out to sea this weekend.

In summary- the Japanese have developed the ability to extract a new (well actually it is old, but new type of gas to us) from deep within the ocean seabed.  This not unlike the recent developments with Shale Gas in the United States.  The process is far from perfect yet (and still in its infancy), but given the recent developments, it is likely that the Japanese will invest more into this project in order to fully realize the potential of this energy source.   a couple of points-  This new gas (methane hydrate) would still be considered a fossil fuel, but would burn cleaner than many of Japan's current energy suppliers (coal). Japan's largest supply of energy (nuclear) is under heavy scrutiny lately after the Fukishima disaster- which could be argued as the largest, most far reaching enviornmental disaster in History.  They are trying to move away from relience on nuclear energy which has resulted in a heavy increase on imported fossil fuels (coal, oil, natural gas)- which has had the consequence of driving up energy prices for its citizens and hurting the economy. If this energy source were to work out/pay out- this would bring much needed relief to Japan's "energy crisis" and relience on imported fossil fuels. This extraction of this new type of energy, like Shale Oil and Gas, is likely very very risky and could have calamatious effects on the surrounding enviornment, if in the event a spill/leak where to happen (this gas is deep deep within the ocean seabed.. A leak would be very very hard to stop). Recent developments could mean movement away from Japan's current trend of investing in (and development of) green energies such as wind, solar, and geothermal. The exact properties of undersea hydrates and how they might affect the environment are still poorly understood, given that methane is a greenhouse gas.   So my questions are: Should Japan pursue this course of action (developing this new type of energy)? What happens if

'Brown Clouds' Are World's Newest Environmental Threat By TINI TRAN AND JOHN HEILPRIN / AP WRITER Friday, November 14, 2008 BEIJING - A dirty brown haze sometimes more than a mile thick is darkening skies not only over vast areas of Asia, but also in the Middle East, southern Africa and the Amazon Basin, changing weather patterns and threatening health and food supplies, the UN reported. The huge smog-like plumes, caused mainly by the burning of fossil fuels and firewood, are known as "atmospheric brown clouds." Cars drive through thick smog on a street in Beijing in September 2008. Enormous brown clouds of pollution hanging over Asia are killing hundreds of thousands of people, melting glaciers, changing weather patterns and damaging crops, the United Nations said. (Photo: AFP) When mixed with emissions of carbon dioxide and other gases blamed for warming the earth's atmosphere like a greenhouse, they are the newest threat to the global environment, according to a report commissioned by the UN Environment Program and released Thursday. "All of these points to an even greater and urgent need to look at emissions across the planet," said Achim Steiner, head of Kenya-based UNEP, which funded the report with backing from Italy, Sweden and the United States. Brown clouds are caused by an unhealthy mix of particles, ozone and other chemicals that come from cars, coal-fired power plants, burning fields and wood-burning stoves. First identified by the report's lead researcher in 1990, the clouds were depicted Thursday as being more widespread and causing more environmental damage than previously known. Perhaps most widely recognized as the haze this past summer over Beijing's Olympics, the clouds have been found to be more than a mile (kilometer) thick around glaciers in the Himalaya and Hindu Kush mountain ranges. They hide the sun and absorb radiation, leading to new worries not only about global climate change but also about extreme weather conditions. "All t

Faced with sky-high electricity rates, small communities across a country known more for garbage than environmental citizenship are finding economic salvation in making renewable energy.
