Oil isn't America's only fuel addiction. Inefficient and environmentally damaging, the corn-ethanol boondoggle will nonetheless be hard to stop.

With the support of Gov. Sarah Palin, mining interests have defeated an Alaska ballot measure that could have blocked a huge proposed mining project. Now, plans are moving forward to exploit the massive gold and copper deposit at Bristol Bay, home of one of the world’s greatest salmon runs.

Congress has repeatedly failed to extend the tax credits for renewable energy, which expire at the end of this year. The gridlock is discouraging investment in renewables and jeopardizing major solar and wind projects throughout the country.

Texas billionaire T. Boone Pickens has always been one to think big. But his sweeping 10-year energy plan for America faces obstacles that may be insurmountable.

The crackdown on dissent surrounding the Beijing Olympics has been a reminder of China’s lingering authoritarianism. Yet for all our differences, the U.S. and China — the world’s two largest emitters of carbon dioxide — have no choice but to work together to tackle climate change.

Paul Ehrlich still believes that overpopulation imperils the Earth’s
future. But the good news is we are approaching a demographic turning
point: Birth rates have been falling dramatically, and population is expected to peak later this century — after that, for the first time in modern history, the world's population
should actually start to decline.

After years of optimistic predictions and false starts, it looks like solar's moment is here at last. Analysts say a pattern of rapid growth, technological breakthroughs, and falling production costs has put solar power on the brink of becoming the world's dominant electricity source.

Until recently, the idea of environmental advocacy was largely unheard of in China. But that’s changing rapidly. At a legal aid center based in Beijing, Xu Kezhu and her colleagues are helping pollution victims stand up for their rights. The second in a series on Chinese environmentalists.

The coal industry, political leaders, and some environmentalists have high hopes for the concept of carbon sequestration, which takes carbon dioxide emissions from coal plants and buries them underground. But so far, this new technology does not live up to the hype.

As the Arctic's sea ice melts, energy and mining companies are moving into previously inaccessible regions to tap the abundant riches that lie beneath the permafrost and the ocean floor. The potential environmental impacts are troubling.

In an interview with Yale Environment 360, best-selling author Michael
Pollan talks about biofuels and the food crisis, the glories of
grass-fed beef, and why environmentalists must look beyond wilderness
to sustainability.

The Bush administration has been widely criticized for placing politics over science when it comes to environmental policy-making. The next president must act to reverse that trend.

Nanotechnology, now used in everything from computers to toothpaste, is booming. But concern is growing that its development is outpacing our understanding of how to use it safely.

President Bush is urging Congress to open the U.S. coasts and the Arctic National Wildlife Refuge to oil and gas drilling. But America must ultimately wean itself off fossil fuels. The question is whether it makes the transition now — or waits until every last one of its unspoiled places has been drilled.

With soaring prices for agricultural goods and new demand for biofuels, the clearing of the world's largest rain forest has accelerated dramatically. Unless forceful measures are taken, half of the Brazilian Amazon could be cut, burned or dried out within 20 years.

As the public seeks answers about the future impacts of climate change, some climatologists are growing increasingly uneasy about the localized predictions they are being asked to make.

Paleontologists and geologists are looking to the ancient past for clues about whether global warming will result in mass extinctions. What they're finding is not encouraging.

A cap-and-trade system is not the answer, according to a leading alternative-energy advocate. To really tackle climate change, the United States must revolutionize its entire energy strategy.

By taking bits of a single gene, scientists are using DNA barcoding to identify new species. If a portable hand-held scanning device can be developed, one ecologist says, it could “do for biodiversity what the printing press did for literacy.”

Quietly and somewhat surprisingly, green groups are cropping up throughout China and are starting to have an impact. In the first in a series on Chinese environmentalists, journalist Christina Larson visits with Zhao Zhong, who is leading the fight to save the Yellow River.
