David Biello has been covering energy and the environment for nearly a decade, the last four years as an associate editor at Scientific American
. He also hosts 60-Second Earth
, a Scientific American
podcast covering environmental news, and is working on a documentary with Detroit Public Television on the future of electricity.

Some scientists and analysts are touting carbon capture and storage as a necessary tool for avoiding catastrophic climate change. But critics of the technology regard it as simply another way of perpetuating a reliance on fossil fuels.
The world has never seen anything like China’s dizzying urbanization boom, which has taken a heavy environmental toll. But efforts are now underway to start using principles of green design and smart growth to guide the nation’s future development.
No more cost-effective way to make major cuts in energy use and greenhouse gas emissions exists than retrofitting buildings. Now, from New York to Mumbai to Melbourne, a push is on to overhaul older buildings to make them more energy efficient.
In the wake of the Fukushima meltdowns, some nations are looking to move away from nuclear power. But not China, which is proceeding with plans to build 36 reactors over the next decade. Now some experts are questioning whether China can safely operate a host of nuclear plants.
What if the ever-increasing amounts of carbon dioxide that are heating up the atmosphere could be used to produce an abundant supply of liquid fuels? The U.S. government and private labs are pursuing that Holy Grail of renewable energy — but for now the cost of large-scale production is prohibitive.
The world’s worst nuclear reactor mishap in 25 years was caused by a massive natural calamity but compounded by what appear to be surprising mistakes by Japanese engineers. The result has been a fast-moving disaster that has left officials careening from one emergency to the next.
To shift the global economy from fossil fuels to renewable energy will require the construction of wind, solar, nuclear, and other installations on a vast scale, significantly altering the face of the planet. Can these new forms of energy approach the scale needed to meet the world’s energy demands?
A prominent marine biologist says the impacts of the oil gushing into the Gulf of Mexico will persist for years, no matter when the flow finally stops. What’s more, scientist Thomas Shirley says that most of the damage remains out of sight below the surface, as creatures succumb to the toxic effects of the rapidly spreading tide of oil.
The drive to extract and store CO2 from coal-fired power plants is gaining momentum, with the Obama administration backing the technology and the world’s first capture and sequestration project now operating in the U.S. Two questions loom: Will carbon capture and storage be affordable? And will it be safe?
Of the various geoengineering schemes being proposed to cool an overheated planet, one approach — extracting carbon dioxide from the atmosphere using “artificial trees” — may have the most potential. But both questions and big hurdles remain before this emerging technology could be widely deployed.
Biofuels – made from algae and non-food plants – are emerging as a potentially viable alternative to conventional jet fuels. Although big challenges remain, the reductions in greenhouse gas emissions could be major.
New solar thermal technology overcomes a major challenge facing solar power – how to store the sun’s heat for use at night or on a rainy day. As researchers tout its promise, solar thermal plants are under construction or planned from Spain to Australia to the American Southwest.
Led by China, the developing world is engaged in a flurry of dam construction, touting hydropower as renewable energy in an era of global warming. But critics point out that the human and environmental costs of dams remain high.
Until now, geothermal technology has only been used on a small scale to produce power. But with major new projects now underway, deep geothermal systems may soon begin making a significant contribution to the world’s energy needs.
