Thanks to state officials who have long supported renewables, Iowa now leads all U.S. states in the percentage of its energy produced from wind. Big companies, including Facebook and Google, are taking notice and cite clean energy as a major reason for locating new facilities there.

Former U.S. Senator Timothy Wirth and former White House Counsel C. Boyden Gray argue that environmental criticisms of corn ethanol are unwarranted and that the amount in gasoline should be increased. In rebuttal, economist C. Ford Runge counters that any revisionist view of ethanol ignores its negative impacts on the environment and the food supply.

The revisionist effort to increase the percentage of ethanol blended with U.S. gasoline continues to ignore the major environmental impacts of growing corn for fuel and how it inevitably leads to higher prices for this staple food crop. It remains a bad idea whose time has passed.

Physicist Klaus Lackner has long advocated deploying devices that extract carbon dioxide from the atmosphere to combat climate change. Now, as emissions keep soaring, Lackner says in a Yale Environment 360 interview that such “air capture” approaches may be our last best hope.

As the world moves to slash CO2 emissions, the shipping and aviation sectors have managed to remain on the sidelines. But the pressure is now on these two major polluting industries to start controlling their emissions at last.

Facing one of the worst droughts in memory, South Africa’s leaders have doubled down on their support of the water-intensive coal industry. But clean energy advocates say the smartest move would be to back the country’s burgeoning wind and solar power sectors.

Donnel Baird has launched a startup that aims to revolutionize how small businesses and nonprofits secure funding for energy efficiency and clean energy projects in low-income neighborhoods. In a Yale Environment 360 interview, he talks about how he plans to bring his vision to dozens of U.S. cities.

India’s megacities have some the deadliest air and worst traffic congestion in the world. But Indian startups are now launching initiatives that link smart-phone apps and private shuttle buses and could help keep cars and other motorized vehicles off the roads.

Surprising new statistics show that the world economy is expanding while global carbon emissions remain at the same level. Is it possible that the elusive “decoupling” of emissions and economic growth could be happening?

Climate scientist James Hansen has crossed the classic divide between research and activism. In an interview with Yale Environment 360, he responds to critics and explains why he believes the reality of climate change requires him to speak out.

One of President Obama’s signature achievements on climate has been strict standards aimed at improving auto fuel efficiency to nearly 55 miles per gallon by 2025. But credits and loopholes, coupled with low gas prices, may mean the U.S. will fall well short of this ambitious goal.

Until recently, little was known about the extent of methane leaking from urban gas distribution pipes and its impact on global warming. But recent advances in detecting this potent greenhouse gas are pushing U.S. states to begin addressing this long-neglected problem.

Low gasoline prices and continuing performance issues have slowed the growth of electric car sales. But that has not stymied progress in electrifying larger vehicles, including garbage trucks, city buses, and medium-sized trucks used by freight giants like FedEx.

Subsistence hunters in the Arctic have long taken to the sea ice to hunt seals, whales, and polar bears. But now, as the ice disappears and soaring temperatures alter the life cycles and abundance of their prey, a growing number of indigenous communities are facing food shortages.

Angel Garcia, of Young Conservatives for Energy Reform, is working to persuade Republicans about the need for renewable energy. In an interview with Yale Environment 360, he explains why his group avoids mentioning climate change when it makes its pitch to conservatives

As part of India's modernization program, Prime Minister Narenda Modi has called for doubling the nation’s coal production by 2020. For the villages in the Jharia coalfield, which is frequently shrouded in smoke from underground fires, the government’s plans have only increased the pressures and dangers of living alongside huge, burning open-pit mines.

In the wake of the Paris climate agreement, developing countries find themselves in need of analysts capable of monitoring their emissions. It’s a complex task, but organizations are stepping in with online courses to train these new green accountants.

China’s lucrative black market for fish parts is threatening the vaquita, the world’s most endangered marine mammal. The porpoises, who live only in the Gulf of California, are getting caught up as bycatch in illegal gill nets and killed.

Development pressures are threatening Istanbul's centuries-old gardens, which have produced food for the city's markets since Byzantine times. A coalition of gardeners and environmentalists is fighting to preserve them.

The U.S. Supreme Court order blocking President Obama’s plan to cut emissions from coal-burning power plants is an unprecedented step and one of the most environmentally harmful decisions ever made by the nation’s highest court.

This year’s El Niño phenomenon is spawning extreme weather around the planet. Now scientists are working to understand if global warming will lead to more powerful El Niños that will make droughts, floods, snowstorms, and hurricanes more intense.
