A new process that simultaneously combines the light and heat of solar radiation to generate electricity could offer more than double the efficiency of existing solar cell technology, say the engineers who discovered it and proved that it works. The process, called 'photon enhanced thermionic emission," or PETE, could reduce the costs of solar energy production enough for it to compete with oil as an energy source.

A New Energy Program with Steve Chu speaking at the Climate Change and Global Politics Conference hosted by the World Affairs Council of Northern California.No one nation can effectively reverse the growing problems caused by our changing climate. Coordinated global efforts - between governments, corporations, and individuals - can help us conserve and develop energy resources, as well as ensure the continued growth of emerging and developed nations.What can political leaders do?

In his thoughtful criticism of my essay on the future of fossil fuels and the poor prospects for renewable energy, Andrew Leonard characterizes my message as one that "we have nothing to worry about." This may be partly the fault of my presentation, because in the course of being provocative I did not make it sufficiently clear that I was engaged in analysis, not advocacy. I made the prediction that, even in the presence of global warming, the countries of the world are unlikely to allow the vast stores of fossil fuels in the earth's crust to lie there undisturbed, when technology is making many of them ever more accessible and cheaper than the renewable energy alternatives. For the record, I personally wish that greenhouse gas emissions would stop immediately, and I personally would prefer a world of harmonious international cooperation for all time. Neither of my personal preferences is going to be fulfilled and neither affects the accuracy of my analysis.

"Those who make peaceful evolution impossible make violent revolution inevitable."- John F. KennedyThere's one thing for sure: 2008 isn't anything like politics as usual.The corporate media (with their unerring eye for the obvious point) is fixated on the narrative that, for the first time ever, Americans will likely end this year with either a woman or a black man headed for the White House. Bloggers are telling stories from the front lines of primaries and caucuses that look like something from the early 60s - people lining up before dawn to vote in Manoa, Hawaii yesterday; a thousand black college students in Prairie View, Texas marching 10 miles to cast their early votes in the face of a county that tried to disenfranchise them. In recent months, we've also been gobstopped by the sheer passion of the insurgent campaigns of both Barack Obama and Ron Paul, both of whom brought millions of new voters into the conversation - and with them, a sharp critique of the status quo and a new energy that's agitating toward deep structural change.There's something implacable, earnest, and righteously angry in the air. And it raises all kinds of questions for burned-out Boomers and jaded Gen Xers who've been ground down to the stump by the mostly losing battles of the past 30 years. Can it be - at long last - that Americans have, simply, had enough? Are we, finally, stepping out to take back our government - and with it, control of our own future? Is this simply a shifting political season - the kind we get every 20 to 30 years - or is there something deeper going on here? Do we dare to raise our hopes that this time, we're going to finally win a few? Just how ready is this country for big, serious, forward-looking change?Recently, I came across a pocket of sociological research that suggested a tantalizing answer to these questions - and also that America may be far more ready for far more change than anyone really believes is possible at this moment. In fac

The United States isn't broke; we're the richest country on the planet and a country in which the richest among us are doing exceptionally well. But the truth is, our economy is broken, producing more pollution, greenhouse gasses and garbage than any other country. In these and so many other ways, it just isn't working. But rather than invest in something better, we continue to keep this 'dinosaur economy' on life support with hundreds of billions of dollars of our tax money.

It's time to rebuild the American Dream; but this time, let's build it better.

A large majority of the American people consistently support the following agenda: Tax the rich and corporations End the wars, bring the troops home, cut military spending Protect the social safety net, strengthen Social Security and improved Medicare for all End corporate welfare for oil companies and other big business interests Transition to a clean energy economy, reverse environmental degradation Protect worker rights including collective bargaining, create jobs and raise wages Get money out of politics

Hansen's proposal makes use of market principles, by prodding the market to tell the truth about the costs of carbon-based energy through prices.

Slovenian philosopher Slavoj Zizek, akaThe Elvis of cultural theory, is given the floor to show of his polemic style and whirlwind-like performance. The Giant of Ljubljana is bombarded with clips of popular media images and quotes by modern-day thinkers revolving around four major issues: the economical crisis, environment, Afghanistan and the end of democracy. Zizek grabs the opportunity to ruthlessly criticize modern capitalism and to give his view on our common future. We communists are back! is the closing remark of Slavoj Zižeks provocative performance. Our current capitalist system, that everyone believed would be smoothly spread around the globe, is untenable. We find ourselves on the brink of big problems that call for big solutions. Whatever is left of the left, has been hedged in by western liberal democracy and seems to lack the energy to come up with radical solutions. Not Zižek.

How can architects build a new world of sustainable beauty? By learning from nature. At TEDSalon in London, Michael Pawlyn describes three habits of nature that could transform architecture and society: radical resource efficiency, closed loops, and drawing energy from the sun.

Greenhouse gas emissions increased by a record amount last year, to the highest carbon output in history, putting hopes of holding global warming to safe levels all but out of reach, according to unpublished estimates from the International Energy Agency.

More and more, we hear that nothing can be done to tax major corporations because of the threat of how they would respond. Likewise, we cannot stop their price gouging or even the government subsidies and tax loopholes they enjoy. For example, as the oil majors reap stunning profits from high oil and gas prices, we are told it is impossible to tax their windfall profits or stop the billions they get in government subsidies and tax loopholes. There appears to be no way for the government to secure lower energy prices or seriously impose and enforce environmental protection laws. Likewise, despite high and fast rising drug and medicine prices, we are told that it is impossible to raise taxes on pharmaceutical companies or have the government secure lower pharmaceutical prices. And so on.

In May 2008, Josh Fox received a letter from a natural gas company offering to lease his family's land in Milanville, Pennsylvania for $100,000 to drill for gas.[1]Following the lease offer, he looked for information about natural gas drilling in the Marcellus Shale under large parts of Pennsylvania, New York, Ohio and West Virginia. He visited Dimock, Pennsylvania where natural gas drilling was already taking place. In Dimock, he met families able to light their tap water on fire as well as suffering from numerous health issues and fearing their well water had been contaminated.Fox then set out to see how communities are being affected in the west where a natural gas drilling boom has been underway for the last decade. He spent time with citizens in their homes and on their land as they relayed their stories of natural gas drilling in Colorado, Wyoming, Utah and Texas, among others. He spoke with residents who have experienced a variety of chronic health problems as well as contamination of their air, water wells or surface water. In some instances, the residents are reporting that they obtained a court injunction or settlement monies from gas companies to replace the affected water supplies with potable water or water purification kits.[2]Throughout the documentary, Fox reached out to scientists, politicians and gas industry executives and ultimately found himself in the halls of Congress as a subcommittee was discussing the Fracturing Responsibility and Awareness of Chemicals Act, "a bill to amend the Safe Drinking Water Act to repeal a certain exemption for hydraulic fracturing."[3] Hydraulic fracturing was exempted from the Safe Drinking Water Act in the Energy Policy Act of 2005.[4]Making appearances in the film are Dr. Theo Colborn, founder of the Endocrine Disruption Exchange (TEDX); John Hanger, Secretary of the Pennsylvania Department of Environmental Protection (DEP); Dr. Al Armendariz, Environmental Protection Agency (EPA) Administrator for Region 6; W

Daniel Nocera talks about his bio-emulative ground breaking innovation to store electricity as plants do.

According to the American Society of Civil Engineers, repairing our crumbling infrastructure will require an investment of $2.2 trillion over five years. (Source: ASCE Report Card for America's Infrastructure) For every $100 billion spent on infrastructure projects such as rebuilding our roads and bridges, public transportation, energy transmission and water systems, 1.8 million jobs would be created. (Source: Heintz, Robert, James Pollin, and Heidi Garrett-Peltier, "How Infrastructure Investments Support the U.S. Economy: Employment, Productivity and Growth." Amherst, MA: Political Economy Research Institute, January 2009) The current Congress hasn't passed a single job-creation bill. Instead of creating jobs, they've been killing them and slowing down the economic recovery with severe budget cuts. In fact, 1.8 million jobs will be lost as a result of the recent debt ceiling deal to cut government spending while failing to extend the payroll tax and emergency unemployment benefits. (Source: The Century Foundation/Economic Policy Institute) A huge share of the nation's economic growth over the past 30 years has gone to the top .1% of Americans, who now make an average of $27 million per household. The average income for the bottom 90% of us is only $31,244.

If, as Lessig conclusively demonstrates, Congress is indifferent to the will of the people and to democratic debate - because it has been captured by monied interests to whose interests it exclusively attends - then the people lose the ability to affect what government does in any realm. It doesn't make much difference which problem you believe is most pressing: this is the dynamic that lies at the heart of it. Inaction on climate issues is due to the power of polluters and energy companies; the power of the private health insurance industry blocks fundamental health-care reform; endless war and civil liberties abuses are sustained by the power of the surveillance and National Security State industries; and a failure to achieve real Wall Street reform is due to the fact that, as Sen. Dick Durbin amazingly acknowledged about the institution in which he serves, "the banks frankly own the place." Without finding an effective way to address that overarching problem, the only recourse for citizens becomes either passive acceptance of their powerlessness (i.e., apathy and withdrawal) or disruption and unrest fomented outside of the electoral system (the driving ethos of OccupyWallStreet).

It's hard to think of another time when there has been such a gulf between intellectuals and activists; between theorists of revolution and its practitioners. Writers who for years have been publishing essays that sound like position papers for vast social movements that do not in fact exist seem seized with confusion or worse, dismissive contempt, now that real ones are everywhere emerging. It's particularly scandalous in the case of what's still, for no particularly good reason, referred to as the 'anti-globalization' movement, one that has in a mere two or three years managed to transform completely the sense of historical possibilities for millions across the planet. This may be the result of sheer ignorance, or of relying on what might be gleaned from such overtly hostile sources as the New York Times; then again, most of what's written even in progressive outlets seems largely to miss the point-or at least, rarely focuses on what participants in the movement really think is most important about it. As an anthropologist and active participant-particularly in the more radical, direct-action end of the movement-I may be able to clear up some common points of misunderstanding; but the news may not be gratefully received. Much of the hesitation, I suspect, lies in the reluctance of those who have long fancied themselves radicals of some sort to come to terms with the fact that they are really liberals: interested in expanding individual freedoms and pursuing social justice, but not in ways that would seriously challenge the existence of reigning institutions like capital or state. And even many of those who would like to see revolutionary change might not feel entirely happy about having to accept that most of the creative energy for radical politics is now coming from anarchism-a tradition that they have hitherto mostly dismissed-and that taking this movement seriously will necessarily also mean a respectful engagement with it.
