Last week saw the opening of the first hydrogen fuelling station in England. The station is based at Birmingham University, where experiments are being carried out to test the viability of hydrogen in transport applications, as part of Birmingham's 'Science City' hydrogen energy project.

From production to processing, transport to trash can, meals and snacks can leave a large environmental footprint. One company aims to slow this trend with a new low-carb menu. Carbs - as in carbon.

OSLO (AFP) - Projects to reduce carbon dioxide emissions in developing countries have prevented 135 million tonnes of CO2 emissions from entering Earth's atmosphere so far, the Norwegian classification group Det Norske Veritas (DNV) said on Monday. The projects, known as Clean Development Mechanisms (CDMs) and defined in the Kyoto Protocol, allow industrialised countries and their companies to finance projects aimed at reducing greenhouse gases in developing countries.

The challenges our society faces with depleted energy resources, water shortages, soaring food costs all point to environmental solutions.

BEIJING, April 28 -- CHINA is looking to expand wind power generating capacity to 100,000 megawatts by 2020, or fivefold the previous target, an industry official said. "The NDRC has just recently completed an internal meeting to discuss the possibility of increasing wind power capacity to 100,000MW," Shi Pengfei, vice president of Chinese Wind Energy Association said, referring to the National Development and Reform Commission, China's top industry planning body. "It's not 20,000MW or 30,000MW as previously targeted."

So far, CNG vehicles haven't made a blip on my radar screen, even though the group Natural Gas Vehicles for America (NGVA) estimates there are 150,000 NGVs on U.S. roads today and over 5 million worldwide. It took a phone call from sunny Southern Utah to clue me in to recent developments, which include a local refueling station overflowing with CNG-hungry vehicles. There are about 1500 CNG refueling stations in the US, which is about the same number of commercial stations offering E85 ethanol blends. Utah has a total of 91 CNG filling stations, most of which are reserved for commercial fleet use, but there are 20 open to the public. According to an article by the Associated Press, you could drive Utah from top to bottom and hit 22 different stations offering compressed natural gas.

The sun blasts Earth with enough energy in one hour-4.3 x 1020 joules-to provide all of humanity's energy needs for a year (4.1 x 1020 joules), according to physicist Steven Chu, director of Lawrence Berkeley National Laboratory. The question is how to most effectively harness it. Thin-film solar cells may be the answer: One recently converted 19.9 percent of the sunlight that hit it into electricity, surpassing the amount converted into power by mass-produced traditional silicon photovoltaics and offering the potential to unleash this renewable energy source.

DOVER, Mass. - On a recent sunny afternoon Bob Loebelenz pauses to gaze 72 feet into the air at the spinning blades of his wind turbine, a small "clean, free electricity" smile creasing the corners of his mouth. While giant wind turbines that supply power to utilities sprout along ridgelines across the United States, far smaller residential wind generators, like the one Mr. Loebelenz erected in 2003 to power his suburban Boston home, are still unusual in densely populated places.

Spiegel Online published a series of pictures titled "Desertec: Strom aus der Wüste" (translation: Desertech: Electricity from the desert). It includes this image of how much land would be needed to power the world, Europe or Germany with solar-thermal power. The idea is similar to a post we did a year ago: How Much Land to Power The Whole World with Solar?

The future of the world's largest offshore wind farm and a symbol of Britain's renewable energy future was thrown into doubt last night after it emerged that Shell was backing out of the project and indicated it would prefer to invest in more lucrative oil schemes.

MOSCOW (Reuters) - Russia will not accept binding caps on its greenhouse gas emissions under a new climate regime, currently being negotiated to succeed the Kyoto Protocol after 2012, top officials said on Monday. Kyoto puts a cap on the average, annual greenhouse gas emissions from 2008-12 for some 37 industrialized countries, including Russia.

An MIT class has estimated the carbon emissions of Americans in a wide variety of lifestyles -- from the homeless to multimillionaires, from Buddhist monks to soccer moms --

The American Petroleum Institute (API), the trade organization for the oil and natural gas industry, has just begun running a feel-good commercial that argues "America's future" lies in drilling out domestic reserves of oil and natural gas off our coasts, in our western lands, and in the Arctic National Wildlife Refuge.
