Clean coal seen as green alternative in Florida
November 29, 2007 02:02 PM - Reuters
St. Petersburg, Florida (Reuters) - Resistance to clean coal-fired electric-generating plants ignores an environmentally viable approach to diversifying energy sources, a Florida power company executive said on Thursday.
Mark Hornick, general manager of Tampa Electric Co's Polk County Plant, said environmental opposition recently caused the power company to defer plans to expand the Polk facility with an improved version of its existing clean-coal technology.
Fire shuts key Canada-US pipeline, oil soars

HOUSTON/LONDON (Reuters) - An explosion crippled the biggest pipeline supplying Canadian crude to U.S. Midwest refineries, shutting off more than one million barrels per day of imports to the world's biggest consumer.
The cause of the explosion on Wednesday that killed two employees was not immediately known.
Sweet fuel supply : Could a fuel cell that runs on glucose save the planet?
November 28, 2007 08:35 AM - Inderscience Publishers
A new type of fuel cell powered with glucose derived from biomass is described in the latest issue of the Inderscience Publication International Journal of Global Energy Issues. The experimental device works by using sunlight to convert the glucose into hydrogen to power the cell, which produces several hundred millivolts.
The use of biological resources, such as food waste and managed high-energy crops, are gradually becoming a viable approach to reducing our reliance on fossil fuels. However, imaginative ways to convert these materials into useful, electrical energy are still required. Renewable biomass resources include starch, cellulose, sucrose, and lactose. These complex sugar molecules can be readily converted to the much simpler glucose molecule with little energy cost through fermentation processes.
Energy efficiency fails to cut consumption: study

In what the study calls "the efficiency paradox," consumers have taken money saved from greater energy efficiency and spent it on more and bigger appliances and vehicles, consuming even more energy in the process.
The Solution to High Carbon Emissions on the Road? Gigantic Trucks!
November 27, 2007 09:03 AM - , Environmental Graffiti
In what at first glance seems like a contradictory move, the British government is pushing gigantic trucks as a way to cut carbon emissions and costs.
The trucks are called LHVs, for longer, heavier vehicles, or “superlorries”. They are similar to the Australian “road trains”, although they are a bit smaller. It consists of two trailers joined together behind a single engine. The trucks can carry 60% more than normal trucks, which cuts down on costs and carbon emissions.
M2E Power Announces Revolutionary New Energy Generation Technology
November 27, 2007 08:59 AM - , Green Progress
M2E Power, Inc, provider of groundbreaking solutions for mobile and large-scale power generation, today announced that it has raised $8M in its Series A funding. OVP Venture Partners led the round, with additional participation from @Ventures, Highway 12 Ventures and existing investors. The company will use the funds to speed commercialization of its patent-pending M2E™ (Motion to Energy) technology, which promises to fundamentally transform the way military and consumer mobile devices are powered. M2E can also be used in larger scale generator applications such as wind power and ocean wave power.
Offshore R.I. wind power projects proposed
November 26, 2007 03:50 PM - Reuters
Allco Renewable Energy Group said on Monday that it plans to develop up to four offshore wind power projects in Rhode Island.
In a release, Allco Renewable, a New York based renewable energy investment firm, said it submitted eight preliminary permit applications to the Rhode Island Coastal Resources Management Council (CRMC) on September 21.
Planting Carbon Deep in the Earth
November 26, 2007 11:43 AM - Univeristy of Leeds
Storing carbon dioxide deep below the earth’s surface could be a safe, long-term solution to one of the planet’s major contributors to climate change.
University of Leeds - Research shows that porous sandstone, drained of oil by the energy giants, could provide a safe reservoir for carbon dioxide. The study found that sandstone reacts with injected fluids more quickly than had been predicted - such reactions are essential if the captured CO2 is not to leak back to the surface.
Leeds Researchers Fueling the "Hydrogen Economy"
November 26, 2007 11:23 AM - Univeristy of Leeds
LEEDS, ENGLAND - Scientists at the University of Leeds are turning low-grade sludge into high-value gas in a process which could make eco-friendly biodiesel even greener and more economical to produce.
Biodiesel – motor fuel derived from vegetable oil - is a renewable alternative to rapidly depleting fossil fuels. It is biodegradable and non-toxic, and production is on the up. But for each molecule of biodiesel produced, another of low-value crude glycerol is generated, and its disposal presents a growing economic and environmental problem.
US Renewable Fuel for UK Power Plant.
November 26, 2007 08:55 AM - , Private Landowner Network
At a time when the US should be scrambling to build more renewable energy capacity at home it is instead on course to export a valuable homegrown renewable fuel: wood chips.
Prenergy Power Limited, of London, England has been given the go-ahead by Britain’s Department of Trade & Industry to build a 350 megawatt powerplant in Port Talbot on the south coast of Wales. The powerplant will be fueled by wood chips that are expected to be imported from the US and Canada. Wood chip fuel will arrive by ship in the deep water port or perhaps by rail car from other sources. The powerplant will burn around three million tons per year from sustainable sources.
