Plankton, base of ocean food web, in big decline. |
| Worldwide phytoplankton levels are down 40 percent since the 1950s, according to a study published Wednesday in the journal Nature. The likely cause is global warming, which makes it hard for the plant plankton to get vital nutrients, say researchers who described their results as both staggering and disturbing. |

Accidents plague China's workplaces. |
| Mishaps that threaten lives and the environment are an everyday occurrence in China's workplaces—in coal mines, fireworks plants or at ports. In the first half of this year, an average of 187 people died per day in industrial accidents, China's government reported this month. |

Ford: Lincoln Hybrid Now Priced Equal to Non-hybrid Models |
Many consumers have become comfortable with hybrid cars' higher sticker price, figuring they will save money on gas in the long run. Now Ford is turning hybrid pricing on its head. Its 2011 Lincoln MKZ hybrid, upon this fall's release, will have a sticker price identical to its twin that runs solely on gasoline. Ford touts that it is the first automaker to offer a luxury hybrid vehicle with a manufacturer’s suggest retail price equal to the same model only using gas. |

BP gets "wake-up call" and $32 billion in spill charges |
BP Plc's newly named chief executive on Tuesday called the Gulf oil spill a "wake-up call" for the entire industry as the company tallied up its losses and disclosed two U.S. investigations.
Bob Dudley, who will replace gaffe-prone Tony Hayward as chief executive on October 1, said safety would be among his highest priorities as the first American to lead BP tries to refurbish the British oil company's battered reputation.
Image repair may become even tougher after BP said it would offset the cost of the spill against its taxes, costing U.S. taxpayers almost $10 billion.
BP reported a second-quarter loss of $17 billion, including $32 billion in charges related to the oil spill, the largest in U.S. history. It also announced plans to sell $30 billion in assets over the next 18 months to help cover its liabilities. |

Gulf Environment Forum 2011 |
ENN is proud to be a media sponsor of the The Gulf Environment Forum. Environmental issues in the middle east are taken very seriously, and there are challenges to living and operating industries in an area with limited water and cooling capacity for industry.
The Gulf Environment Forum (GEF) is Saudi Arabia’s official environment event, spearheaded by the presidency of Meteorology & Environment. Combining an international exhibition and conference, GEF provides a unique business platform for industry experts to demonstrate their expertise and play an active part in establishing a sustainable and environmentally responsible region for generations to come. |

Gulf seafood tested for oil but not dispersant. |
| No one is testing seafood to tell whether it has absorbed the toxic compounds found in the nearly 1.8 million gallons of dispersants BP has poured into the water to break up the oil. |

Ten Nations at 'Extreme Risk' Because of Water Shortages, Report Says |
| Ten countries worldwide, including five African nations, are at "extreme risk" because of limited access to clean, fresh water, according to a new global water security index. And the effects of climate change and population growth will exacerbate the stress on these water supplies, potentially threatening stability in many regions, according to the analysis by Maplecroft , a UK-based consulting group. |

Signs of reversal of Arctic cooling in some areas |
| (Helmholtz Association of German Research Centres) Parts of the Arctic have cooled clearly over the past century, but temperatures have been rising steeply since 1990 also there. This is the finding of a summer temperature reconstruction for the past 400 years produced by tree rings from regions beyond the Arctic Circle. German and Russian researchers analysed tree growth using ring width of pine from Russia's Kola Peninsula and compared their findings with similar studies from other parts of the Arctic. |

Empa grows 'sea urchin'-shaped structures |
| (Swiss Federal Laboratories for Materials Science and Technology (EMPA)) Empa researchers have succeeded in growing sea-urchin shaped nanostructures from minute balls of polystyrene beads using a simple electrochemical process. The spines of the sea urchin consist of zinc oxide nanowires. The structured surface should help increasing the efficiency of photovoltaic devices. |

Sandia National Laboratories and SunPower Corp. extend solar energy research partnership |
| (DOE/Sandia National Laboratories) Sandia National Laboratories and SunPower Corp. recently formalized an agreement to conduct research on integrating large-scale photovoltaic (PV) systems into the grid. By signing a Cooperative Research and Development Agreement, the organizations will leverage approximately $1 million of combined US Department of Energy and SunPower funding. Additionally, a consortium led by SunPower, which includes Sandia as a partner, was recently awarded a $1 million grant from the California Solar Initiative to improve modeling of high-penetration PV systems. |

Reattaching Giant Sponges |
| The animated character Spongebob Squarepants is running loose on the ocean floor everyday of the week after school on the Nickelodean channel. And so are Spongebob's real-life cousins the Giant Barrel sponges, though not by choice.
Giant sponges? Yep. Think of big oil drums, but squishy. And, like oak trees in a meadow, they dominate the reefs they live on. Undisturbed they live to be hundreds, even thousands of years old.
Joseph Pawlick of the University of North Carolina-Wilmington says that storms, marine debris and human items such as anchor chains dislodge these gentle giants. Once loose, eroded by the currents, these man-sized sea sponges of the Caribbean slowly die.
Pawlick says it's vital to reattach stray sponges, if they are to survive. Now his team has developed a solution made from everyday PVC pipes. Anchored into concrete blocks on a plastic mesh base, they clip a sponge in place until it naturally attaches itself back to underlying reef.
So far, ninety percent of sponges clipped in deep water have survived, many reattaching to the reef in as little as six months.
It's a clever idea that's giving roots -- and a new chance for survival -- to the Giant Barrel sponge.

Farming the Wind |
| Farming has always been subject to the uncertainties of weather and market conditions. But farmers in Huron County, Michigan, have found something they finally can count on.
The wind!
Blowing across Lake Huron, the wind there is always ripe for harvesting. A patch of thirty two turbines have already been planted. And plans for 42 more are underway.
Bob Krohn, a farmer in the area, anticipates reaping up to $30,000 per year from just three windmills on his property. It's a welcome source of revenue where incomes are fifteen percent below the national average.
Michigan is another in a growing list of farm belt states like Texas, Iowa, Minnesota and others, where wind power is becoming a major industry. Many of these states require utilities to generate a certain percentage of electricity from alternative sources. Other than concerns about creating hazards for birds, windmills are readily accepted in rural areas.
In fact, some see them as a way of preserving our rich agricultural heritage. After all, what would you prefer in your backyard? A subdivision of homes, coal-burning power plant, or wind turbines?

Airborne Windmills |
| Up in the air -- it's a bird; it's a plane; it's a -- flying windmill?
That's right, a flying windmill. Who knew. It looks like a cross between a kite and helicopter that's tethered to the ground. This brainchild of engineer Dave Shepard hovers six miles above ground where the jet stream blows faster and more consistently. It captures 100 times more energy than it's terrestrial counterparts, and Shepard believes it could produce electricity for about half the cost of power from traditional plants. Barely visible to the eye, it wouldn't mar the landscape or pose a threat to birds since they don't fly that high.
Magenn Power of Canada has another idea. That firm developed an airborne system resembling an inflatable paddle wheel that uses helium to keep it aloft. Another design by a Dutch astronaut is a kind of giant kite connected to a ground station via cable. As the kite gets reeled out by the wind, it turns an electric generator.
While none of these inventions are currently in widespread use, they've already proven one thing: When it comes to inventing new ways to produce clean, sustainable energy -- the sky is the limit.
