Breakthrough Producing Hydrogen from Water + Sunlight : TreeHugg. Image: Angewandte Chemie, WileySunlight + Water = Hydrogen GasScientists at the University of East Anglia, led by Dr.
Thomas Nann, report a breakthrough in the production of hydrogen from water using the energy of sunlight. Amidst all the hype about a potential hydrogen economy, which would rely upon the highly energetic and clean burning hydrogen atom, one of the big questions has been whether sufficient hydrogen can be produced without using yet more energy to create the hydrogen. Typical production methods include stripping hydrogen from other fuels like methane or using electrolysis to split the hydrogen out of water. But with efficiencies between 20 and 40% for producing energy from traditional photovoltaic processes, the hydrogen economy cannot be solar powered.
Or can it?
Climate change. Emirate Channeling Oil Wealth Into Bid for Green Economy - NYTim. Gas-industry report claims wind-energy standards lead to polluti. A new report from Colorado's natural gas industry says increased use of wind energy indirectly results in raised pollution levels produced by some coal-fired power plants along the Front Range.
Critics say the report, released Monday, is flawed. The report recommends curbing the use of wind energy during the next one or two years to levels that match power output at existing natural gas-fired power plants -- and building more natural gas plants in the long term.

April 14, 2010 The U.S. Department of the Navy has set a goal to reduce its reliance on fossil fuels from volatile areas of the world, in part by increasing its use of biofuels. The Navy recently announced five energy targets for the Navy and Marine Corps, and biofuels are a major component of four of those five energy targets. Paper or plastic? State high court to weigh in. The state Supreme Court jumped into the grocery bagging wars Thursday and agreed to decide whether a city can ban plastic bags at retail stores without studying the environmental effects of the increased use of paper.
The court's unanimous vote to review a case from Manhattan Beach (Los Angeles County) will not affect San Francisco, which enacted the nation's first citywide ban on nonbiodegradable plastic bags at supermarkets and chain drugstores in 2007. But the ruling will affect other cities considering such measures, including Oakland. The city passed an ordinance similar to San Francisco's in 2007 but dropped it after a judge blocked its enforcement in response to a lawsuit by the plastic bag industry.
San Jose has begun an environmental study as a first step toward a possible plastic bag ban; and Palo Alto, in response to an industry suit, agreed in July 2009 to conduct a study before adopting a similar ordinance. The case is Save the Plastic Bag Coalition vs. Paper or Plastic? - KQED QUEST Radio Report. Last November, San Francisco became the first city in the country to outlaw plastic check out bags at large supermarkets, arguing that the bags are dangerous to marine life and hard to recycle.
But some studies say paper bags can be just as harmful for the environment. So why target plastic?

Climate change will make invasive plants even more dominant in the landscape, a study by a team of researchers including three Harvard scientists has found.
Published in the online journal PLoS One, their paper is the first demonstration that climate change likely plays a direct role in promoting non-native species’ success, according to a press release from Harvard’s Faculty of Arts and Sciences. “Climate change will lead to an as-yet unknown shuffling of species, and it appears that invasive species will become more dominant,” Charles C. Davis (one of the researchers, and an assistant professor in Harvard’s department of organismic and evolutionary biology) said in the press release.

Starting in July 2011, new sources of at least 100,000 tons of greenhouse gases a year and any existing plants that increase emissions by 75,000 tons will have to seek permits, the agency said.
In the first two years, the E.P.A. expects the rule to affect about 15,550 sources, including coal-fired plants, refineries, cement manufacturers, solid waste landfills and other large polluters, said Gina McCarthy, the agency’s assistant administrator. She said the rule would apply to sites accounting for about 70 percent of the nation’s greenhouse gas emissions. Live video link from the ROV monitoring the damaged riser.
