I have a Going Green piece up on the mainpage that examines the ecological impact of the BP oil spill on the Gulf and its coast, a year after the Deepwater Horizon sunk. The verdict: so far the environmental damage seems much less than many scientists feared initially, thanks to an aggressive response, hungry bacteria and a lot of good …

Fresh Concerns Emerge as Japan Unveils Timetable for Fukushima Shut Down
Assessing the full impact of Japan’s crisis has been a moving target since the first minutes after the 9.0 earthquake struck on March 11. So it’s with a cautious sense of optimism that Sunday’s news from Tokyo Electric and Power Company (TEPCO) – that the crippled power plant could be in cold shut down before the end of the year …
The Planet’s Natural Air Filters
The Earth as one great organism has always been one of the most appealing metaphors of the green movement. From the moment environmentalist James Lovelock first articulated his so-called Gaia hypothesis—after the Greek goddess of the Earth—in the 1970s, the theory has continued to charm environmentalists.
It doesn’t stand up to …
A Win for Clean Air in the Southeast—and a Blow to Coal
Yesterday Tom Fanning, the CEO of the majority coal-powered utility Southern Company, made a few headlines when he told the U.S. Chamber of Commerce in a speech that the Obama administration has “virtually declared war on coal,” continuing:
The existing coal industry is under attack by some in America. Decisions are being made today

How the Ice in Your Drink is Imperiling the Planet
Want to save the Earth? Easy, just buy a couple of ice trays. To the long list of human inventions that are wrecking global climate—the internal combustion engine, the industrial era factory—add the automatic ice maker.
Climate modelers have long known that households are far bigger contributors to global warming than most …
Frack: Is Shale Natural Gas Worse for the Climate Than Coal?
Natural gas is riding high. Long an overlooked energy source, gas is suddenly front and center in the energy picture—in a presidential address, in the business world, on the cover of Time magazine. That’s mostly due to shale gas—new deposits of natural gas found throughout much of the country, and tapped via hydraulic fracturing. …
Is the U.S. Ready for a Nuclear Emergency?
On Friday, Japan faced another round of assessing the damage from a massive aftershock — the strongest in over 400 in the last month — that struck off the north coast late last night. At least three people were killed in the quake and more than 140 injured, and as of Friday evening, millions in the disaster-struck region were again …
Can Green Energy Scale? Wind Power Is Getting There
It’s a question we ask all the time: when will green energy scale up? After all, renewable power won’t really make a difference until it can provide a bulk of the country’s energy supply. That hasn’t happened yet—while technically renewable sources provide around 20% of U.S. power, nearly all of that is biomass or hydro. Wind …
A New Scorecard Ensures That Clean Tech Stays Clean
I’m just back from the Fortune Brainstorm Green conference, wanted to note a new ranking of global solar companies coming from the Silicon Valley Toxics Coalition (SVTC). It’s not a ranking of the best solar panel companies, or the ones with the biggest sales. Instead, SVTC has analyzed which solar companies do the best job of minimizing …
GE Scales Up on Solar
It’s good news for solar advocates and bad news for competitors—General Electric is ready to break into the solar cell business in a major way. The $218 billion company announced today that it had built a solar module with the highest-ever efficiency rate for cadmium-telluride thin film—the most popular low-cost solar technology—at …
