In February, President Obama called for a doubling of the US renewable energy capacity within three years. Yesterday, Obama visited a wind energy company in Newton, Iowa and again emphasized the importance of new forms of power generation: "Now, the choice we face is not between saving our environment and saving our economy. The choice we face is between prosperity and decline. We can remain the world's leading importer of oil, or we can become the world's leading exporter of clean energy." vote nowBuzz up! With billions in stimulus dollars heading toward improving the electricity grid and building sustainable energy infrastructure, emission-free power may be coming to your neighborhood sooner than you think. Here are five of the biggest, most ambitious projects that are in the pipeline, both in the US and elsewhere.

United Nations Secretary General Ban Ki Moon has warned that without a comprehensive international agreement to reduce the greenhouse gas emissions that lead to global warming, humanity faces "oblivion." "The world's scientists have spoken with one voice: the situation is grim and urgent action is needed," Ban said. "The situation is so desperately serious that any delay could push us past the tipping point, beyond which the ecological, financial and human costs would increase dramatically.

The designers, engineers, and others tackling the environmental problems we face never cease to come up with amazingly imaginative ideas. Here are some of our favorite recent projects:

Here's one for the alternative wind power experiments file - a report from BusinessWeek on an interesting design idea, inspired by the Tacoma Narrows Bridge collapse of 1940 - Humdinger's Wind Power Alternative. As an MIT engineering undergraduate visiting the rural fishing village of Petite Anse, Haiti, in 2004, Shawn Frayne hoped to devise a way to convert abundant agricultural waste into cheap fuel. But the budding engineer soon found that the community's mainly poor residents faced an altogether more immediate need. Unconnected to the local power grid, they relied heavily on dirty kerosene lamps, which are not only costly to operate but also unhealthy and dangerous. He decided to devise an alternative-a small, safe, and renewable power generator that could be used to power LED lights and small household electronics, such as radios.

The U.S. environmental movement is failing - by any measure, the state of the earth has never been more dire. What's needed, a leading environmentalist writes, is a new, inclusive green politics that challenges basic assumptions about consumerism and unlimited growth. by james gustave speth A specter is haunting American environmentalism - the specter of failure. All of us who have been part of the environmental movement in the United States must now face up to a deeply troubling paradox: Our environmental organizations have grown in strength and sophistication, but the environment has continued to go downhill, to the point that the prospect of a ruined planet is now very real. How could this have happened?

I must admit that I have been a bit nonplussed to see that the peak oil community seems to share the oil industry's dismissal of wind power as irrelevant and useless in the face of the currently energy challenge (maybe I am unfairly judging from a few individuals' comments, but it's definitely an existing undercurrent in the community). So, in reaction, let me put up here a few arguments that suggest that wind could play a major role in solving our current energy woes - not a silver bullet, but rather more than a side show. First, the "wind is too small to make a difference" argument: well, so was nuclear, until it got big enough. Wind is following the exact same growth trajectory [as shown below].

Our American way of life is unsustainable; rather than attempting to perpetuate it, we must transition beyond it-quickly. Should we fail to do so, our society will collapse-in the not-too-distant future… Message to mainstream America: our American way of life-300+ million people enjoying historically unprecedented living standards-has been enabled by our increasingly dysfunctional ecological and economic behavior over the past 200 years. Our existing way of life is therefore unsustainable; in fact, America is facing imminent societal collapse.

KINGSTON, Ontario, Jun 25 (IPS) - North America's abject failure to meet the challenge of climate change has been "un-American", environmentalist and scientist David Suzuki told delegates Tuesday at the World Wind Energy Conference, the first ever in the region. "We're facing an ecological crisis, a crisis far, far worse than Pearl Harbour," Suzuki said. Twenty years ago this week, one of the United States' leading scientists warned Congress of the imminent danger of climate change and said that waiting decades to take action was too risky. Now James E. Hansen of the National Aeronautics and Space Administration has published new research indicating that greenhouse gas concentrations have pushed the climate near a dangerous tipping point that will unleash far-reaching changes in the atmosphere and oceans that could take millennia to reverse.

PETROL should be included in Australia's carbon emissions trading scheme, but low-income households should be compensated for higher power and fuel bills, the nation's top climate change expert has warned. Issuing a stern challenge to the Rudd Government to include petrol in the scheme, when it begins in 2010, Ross Garnaut warned of dire consequences for Australia's natural icons unless urgent and decisive action is taken.

A bipartisan group of 27 elder statesmen is sending an open letter to both presidential candidates and every member of Congress saying the country faces "a long-term energy crisis" that threatens the security and prosperity of future generations if swift action isn't taken.
