Shopping List: Milk, cereal, bread, carbon offsets

A Norway shopping mall is offering customers carbon offsets for purchase on its shelves. John Acher from Reuters reports that the Stroemmen Storsenter shopping centre outside Oslo began selling the certificates on Saturday, at 165 Norwegian crowns (US$30.58) per tonne for shoppers to pick up with their weekly groceries. In one weekend, more than 300 Carbon Emissions Reductions (CERs) had been sold, and store managers were considering stocking up with more. >> Read the Full Article

Could Waste Heat From Car Exhausts Be Recycled To Help Power Cars?

Professor Mike Rowe's long term research interest at the Cardiff School of Engineering has been in thermoelectric generation - employing thermocouples to convert heat into electricity. The conversion technology is used in everyday applications such as controlling the central heating system or refrigerator temperature. >> Read the Full Article

Dust in West up 500 percent in past 2 centuries

The West has become 500 percent dustier in the past two centuries due to westward U.S. expansion and accompanying human activity beginning in the 1800s, according to a new study led by the University of Colorado at Boulder. Sediment records from dust blown into alpine lakes in southwest Colorado's San Juan Mountains over millennia indicates the sharp rise in dust deposits coincided with railroad, ranching and livestock activity in the middle of the last century, said geological sciences Assistant Professor Jason Neff, lead author on the study. The results have implications ranging from ecosystem alteration to human health, he said. >> Read the Full Article

Fiber Nanogenerators Put the Power in Power Walking

Researchers led by Zhong Lin Wang at the Georgia Institute of Technology’s School of Materials Science and Technology, are developing power fibers that can be used to manufacture shirts and other clothing that can convert energy released during physical motion into electrical energy capable of powering small electronic devices in the field. Applications are widespread and extend beyond soldiers and other military personnel using such power generating clothing to scientists, engineers and other researchers, as well as everyday people eventually wearing them to sustain our ever expanding reliance and fascination with portable electronic devices. >> Read the Full Article

New solar technology greatly improves performance

A new coating for solar panels could lead to more efficient solar collection. The energy from sunlight falling on only 9 percent of California’s Mojave Desert could power all of the United States’ electricity needs if the energy could be efficiently harvested, according to some estimates. Unfortunately, current-generation solar cell technologies are too expensive and inefficient for wide-scale commercial applications. >> Read the Full Article

Butterfly fish 'may face extinction'

A beautiful black, white and yellow butterflyfish, much admired by eco-tourists, divers and aquarium keepers alike, may be at risk of extinction, scientists have warned. The case of the Chevroned Butterflyfish is a stark example of how human pressure on the world’s coral reefs is confronting certain species with ‘blind alleys’ from which they may be unable to escape, says Dr Morgan Pratchett of the ARC Centre of Excellence for Coral Reef Studies Media Release and James Cook University. >> Read the Full Article

Using organic fertilizers could protect against climate change

Los Angeles, London, New Delhi, and Singapore (25 February, 2008) – Applying organic fertilizers, such as those resulting from composting, to agricultural land could increase the amount of carbon stored in these soils and contribute significantly to the reduction of greenhouse gas emissions, according to new research published in a special issue of Waste Management & Research (Special issue published today by SAGE). >> Read the Full Article

Heathrow expansion sets business against environment

LONDON (Reuters) - Four environmental campaigners breached security at London's Heathrow airport on Monday, climbing aboard a parked aircraft and unfurling a banner protesting against runway expansion plans. Police later arrested the four from Greenpeace who walked through security at one of the world's most policed airports. >> Read the Full Article

China orders listed firms to be greener

BEIJING (Reuters) - Beijing has launched a "green securities" scheme aimed at making it harder for polluters to raise capital and requiring listed firms to disclose more information about their environmental record. The initiative is part of a drive by the State Environmental Protection Administration (SEPA) to enlist other government agencies to give financial and economic policies a green hue. >> Read the Full Article

CLP to develop world's largest solar power station

HONG KONG (Reuters) - An Australian subsidiary of CLP Holdings Ltd, the larger of Hong Kong's two power utilities, has agreed with Melbourne-based Solar Systems to develop the world's largest solar power station. TRUenergy will contribute an initial A$7 million ($6.5 million) to develop a 2-megawatt heliostat concentrated photovoltaic pilot plant, subsequently investing up to A$285 million to build the remaining stages of the 154 megawatt project in northern Victoria, Australia, CLP said. >> Read the Full Article
