Hydrogen fuel cells are future, says WWM boss

USING fuel cells powered by hydrogen will help the next generation of harbour tugs to cut emissions, according to Michiel Wijsmuller, managing director of WorldWise Marine Engineering (WWM). Part of the Offshore Ship Designers group, WWM is working with tug operators Ijmuiden-based Iskes and Rotterdam-based Smit to develop a 50 tonne bollard pull harbour tug that will have zero emissions when on standby and very low emissions in service.

Exxon facing shareholder revolt over approach to climate change
May 19, 2008 08:50 AM - Andrew Clark at guardian.co.uk

A shareholder revolt at ExxonMobil led by the billionaire Rockefeller family has won the support of four significant British institutional investors who will call on Monday for a shakeup in the governance of the world's biggest oil company.

Energy Efficiency: Overlooked and Misunderstood

U.S. energy consumption at the end of 2008 is expected to total half of the energy consumed in 1970, according to a new report. Yet the success in energy efficiency during the last 30-plus years has been paid little homage, and future gains are threatened by inaction, says “The SIze of the U.S. Energy Efficiency Market: Generating a More Complete Picture” from the American Council for an Energy-Efficient Economy.

Quietly, wind farms spread footprint in U.S
May 19, 2008 07:20 AM - Reuters

ROCK PORT, Missouri (Reuters) - At 265 feet tall, four gleaming white wind turbines tower over the tiny farm town of Rock Port, Missouri, like a landing of alien intruders. But despite their imposing presence and the stark contrast with the rolling pastures and corn fields, the turbines have received a warm welcome here.

$2 Billion Wind Turbine Order Is Largest Ever

Texas oilman T. Boone Pickens has placed an the largest ever order for wind turbines: he ordered 667 wind turbines from GE, each costing $3 million dollars, making the total order $2 billion. Picken plans to develop the world’s largest wind farm in the panhandle of Texas. The $2 billion order is just one quarter of the total amount he plans to purchase.

Fuel cells: distant dream, but burning with promise
May 15, 2008 08:46 AM - Cornell Chronicle Online

Some day, fuel cells may power your car and exhaust only water and perhaps carbon dioxide. More efficient and cleaner than an internal combustion engine, their emissions will be much lower. They may also run your home without the energy loss of power lines, or even power your laptop or cell phone. But not today or even tomorrow.

How new U.S. biofuel legislation will subsidize oil consumption
May 14, 2008 08:42 AM - Cornell Chronicle Online

New U.S. energy legislation mandates the use of renewable fuel but calls for continuing current biofuel subsidies that will cost taxpayers billions of dollars. The subsidies -- tax credits -- by themselves encourage ethanol production as a replacement for oil-based gasoline consumption. Instead, the tax credits will play a major role in unintentionally subsidizing gasoline consumption. This contradicts the new energy bill's stated objectives of reducing dependency on oil, improving the environment and enhancing rural prosperity.

Recipe for energy saving unravelled in migratory birds
May 14, 2008 08:38 AM - Public Library of Science

Pointed wings together with carrying less weight per wing area and avoidance of high winds and atmospheric turbulence save a bird loads of energy during migration. This has been shown for the first time in free-flying wild birds by researchers at Princeton University, the University of Montana, and the German Max Planck Institute for Ornithology. They state in PLoS ONE’s May 14th edition that climate change might have a critical impact on small migrants’ energy budgets if it causes higher winds and atmospheric instability as predicted.

OPINION Biofuels 2.0: It’s Time for Congress to Act
May 13, 2008 09:26 AM - Christopher Flavin, Worldwatch Institute

Efforts to replace oil with biofuels in the United States are at a critical juncture. Double-digit growth in the production of corn-based ethanol has contributed to a sharp increase in grain and soybean prices while failing to deliver the environmental gains that had been hoped for. It's time to reduce the incentives for food-based biofuels and accelerate the transition to more sustainable alternatives - the so-called "next-generation" cellulosic technologies, which are expected to become viable in the coming years.

Solar Industry Needs Workers
May 13, 2008 09:22 AM - , Organic Consumers Association

California's fascination with solar power has created thousands of jobs in the state and will probably add thousands more, according to a new survey of the industry. The survey, by two community college researchers, estimates that solar companies in California now employ between 16,500 and 17,500 people and may hire another 5,000 in the next year.
