Swedish company Home Energy recently revealed an innovative wind turbine that spins in a spherical formation. Eschewing traditional rotors for a sleek orb structure, this beautiful rethinking of conventional wind turbine design utilizes the Venturi principle, which funnels wind within the turbine's blades. The resulting spherical wind turbine features increased efficiency and lower noise levels - making it ideal for small scale energy needs such as personal home use. Best of all it's called the Energy Ball: the fun name is an added bonus.

We could be generating huge amounts of power from sewage. The process is pretty simple - just ferment sewage to produce a fuel called biogas. Biogas is almost entirely methane, and so is natural gas, so the two are essential interchangeable. The potential to produce biogas is almost entirely overlooked by most countries - except Sweden.

A company called Green Energy Capital Partners based in Philadelphia is planning to build what they term as the second largest solar energy plant in the nation, in the Carbon County. The $60 million, 100-megawatt solar energy plant will be built on 100 acres of land near the Green Acres Industrial Park in Nesquehoning. The solar energy plant is predicted to contain 40,000 solar panels on rotating mounts.

As soon as I have finished this column I will jump on the train to Kent. Last year Al Gore remarked: "I can't understand why there aren't rings of young people blocking bulldozers and preventing them from constructing coal-fired power plants." Like hundreds of honorary young people, I am casting my Zimmer frame aside to answer the call. Everything now hinges on stopping coal. Whether we prevent runaway climate change largely depends on whether we keep using the most carbon-intensive fossil fuel. Unless we either leave it - or the carbon dioxide it produces - in the ground, human development will start spiralling backwards. The more coal is burnt, the smaller are our chances of future comfort and prosperity. The industrial revolution has gone into reverse.

James Hansen, one of the world's leading climate scientists, will today call for the chief executives of large fossil fuel companies to be put on trial for high crimes against humanity and nature, accusing them of actively spreading doubt about global warming in the same way that tobacco companies blurred the links between smoking and cancer.

VW has been talking for a long time about its L1 concept, so called because it uses a measly 1 liter of gasoline to go 100 km. For us Americans, that translates to about 230 miles per gallon.

The disconnect between peak oil concerns and the presidential race is almost total. As prices at the pump rise, each candidate is now talking about their so-called solutions to the problem. Despite clear new warning signs from Russia, Saudi Arabia, Mexico, and Nigeria that peak oil is nigh, the candidates remain unwaveringly oblivious to the true causes of rising fuel prices, preferring instead to dwell on irrelevant-actually, counterproductive-measures like suspending the federal gas tax during the summer months or taxing Big Oil. This is akin to putting a band-aid on a melanoma.

In this small region of Nigeria known as the "south-south," something huge is happening. The adverse effects of oil exploration have been unfolding in the Niger Delta for the past 50 years. Now, the people have had enough. From environmental activism to peaceful protest to stakeholder dialogs, nothing has worked. A new brand of militancy has emerged in a different kind of attempt to call attention to the desperate poverty and injustice.

A leading energy body is calling for a $45 trillion (£23 trillion) green revolution to tackle global warming. The International Energy Agency (IEA) said nations must spend 1% of annual economic output on new technology to halve carbon dioxide emissions by 2050.

LONDON: The government opened a major new phase on Wednesday in its drive for renewable energy, calling for bids to build up to 25 gigawatts of offshore wind turbines, triple the amount in the pipeline. The announcement by the government agency, the Crown Estate, which owns the seabed surrounding the country was welcomed by British Wind Energy Association chairman Adam Bruce as "impressively bold."

We have been, for quite some time, up against a corporate-funded, what I have called global warming denial machine, or disinformation campaign, whose fundamental aim has been to create an exaggerated sense of scientific uncertainty about human-driven global warming and its consequences.

The UK government's renewables consultation called for a green revolution in energy. In doing so, it created a perfect tabloid rod for its own back. The proposed cost-to-consumer calculated by the Department of Business were based on the vanishingly unlikely prospect of an oil price as low as $70 a barrel in 2020. Expected additions to UK energy bills, at that oil price, would be 10-13% for electricity and 18-37% for gas, the government said.

T. Boone Pickens is a billionaire oil man and a career corporate raider who loves George Bush so much he donated $250,000 to his 2004 inaugural ball. He was, and still is, fully behind the invasion and occupation of Iraq and makes no bones about it. So why is he now pushing for the use of alternative energy sources like wind and solar in his Pickens Plan?

A new energy concept called a solar tower could generate enough electricity for 200,000 homes. Looking like a giant smokestack, it would release no noxious fumes - just sun-heated air.

There are times in the history of our nation when our very way of life depends upon dispelling illusions and awakening to the challenge of a present danger. In such moments, we are called upon to move quickly and boldly to shake off complacency, throw aside old habits and rise, clear-eyed and alert, to the necessity of big changes. Those who, for whatever reason, refuse to do their part must either be persuaded to join the effort or asked to step aside. This is such a moment. The survival of the United States of America as we know it is at risk. And even more - if more should be required - the future of human civilization is at stake.

Engineers and scientists at The University of Texas at Austin have achieved a breakthrough in the use of a one-atom thick structure called "graphene" as a new carbon-based material for storing electrical charge in ultracapacitor devices, perhaps paving the way for the massive installation of renewable energies such as wind and solar power. The researchers believe their breakthrough shows promise that graphene (a form of carbon) could eventually double the capacity of existing ultracapacitors, which are manufactured using an entirely different form of carbon. "Through such a device, electrical charge can be rapidly stored on the graphene sheets, and released from them as well for the delivery of electrical current and, thus, electrical power," says Rod Ruoff, a mechanical engineering professor and a physical chemist. "There are reasons to think that the ability to store electrical charge can be about double that of current commercially used materials. We are working to see if that prediction will be borne out in the laboratory."

The head of the U.S. Environmental Protection Agency lied to Congress about his rejection of a request from California meant to curb global warming emissions, Sen. Barbara Boxer said on Tuesday. Boxer, a California Democrat who has called for EPA chief Stephen Johnson to resign, made the statement at a hearing on regulation of greenhouse gases under the U.S. Clean Air Act.

T. Boone Pickens, a conservative billionaire who made his money in oil, is creating strange bedfellows with his aggressive plan for renewable energy such as wind power and natural gas. Last month, he held two conference calls with more than 27,000 members of the Sierra Club to talk up the plan. The environmental group, with some reservations, is on board. Last week, he met with Al Gore. Today, he is scheduled to be on the University of Michigan campus, selling his ideas to students. He said he expects a packed house.

In a high profile campaign, West Virginia citizens have asked for a last minute 'stay of execution' against the imminent destruction of the site of a proposed wind farm on the state's Coal River Mountain. Handing in a petition, signed by more than 8,000 residents, campaigners today called on State Governor Minchin to make good on his commitment to support the development of renewable energy in the state, and order a halt to the destruction of an area with enough wind power potential to supply 150,000 homes.
