Turning Wastewater into Energy

read
NYC looks to the renewable energy potential of sewage treatment.

Processing sewage is a challenging and expensive endeavor, one that can contaminate the surrounding environment. NYT reports that New York City's Department of Environmental Protection is looking at ways to turn the costly and polluting process into one that creates energy and income. Naturally occuring algae at New York waste plants produce sludge and butanol that can be converted into a......read more

The Problem with Natural Gas

read
New research suggests that the footprint of natural gas development is worse than coal.

Natural gas is hailed by proponents as the crucial link between dirty fossil fuels and renewable power. But two new studies, to be published this week, suggest that natural gas development may be doing more to warm the planet than burning coal. The research reports, discussed in an NYT article by Tom Zeller Jr., say that newly developed techniques for tapping natural gas reserves — such as......read more

Natural Gas Won't Solve Global Climate Woes

read
It may burn cleaner than coal, but natural gas may be worse for the climate, says study

Advocates of natural gas development like to tout the fuel's environmental benefits. They argue that it burns cleaner than coal, with significantly fewer emissions. Which is true. But according to new research, switching from coal to natural gas won't do much to curb cimate change. Why? Methane leaks. Methane leaks from pipelines and wellheads are a reality of natural gas production.......read more

The Climate War's Second Front

read
With limited progress on CO2 emissions, a group of nations turn to other pollutants

We have long known that carbon dioxide is not the only pollutant that causes climate change. But, to date, the global effort to address global warming has largely centered on that grandaddy of greenhouse gases -- with next to no meaningful progress. Now, the climate war is opening a second front. Last week, the the United States and five other countries announced a new initiative to......read more

Arctic Methane Emissions an 'Economic Timebomb'

read
Rapid thawing of Arctic permafrost could cost the global economy $60 trillion, study says

Methane release in the Arctic could aggravate the effects of climate change to the tune of $60 trillion over coming decades, according to a paper published in the journal Nature. Governments and industry have expected an economic boon from widespread warming of the Arctic, allowing for the exploitation of new gas and oilfields and enabling faster shipping between Europe and Asia. But the release......read more

Waste Methane Hits Car Fuel Market

read
The first commercially distributed renewable biogas is now available in California

Landfills, dairy farms and sewage plants produce clean-burning, totally renewable methane as a waste by-product. Now, thanks to Clean Energy Fuels, that biofuel has entered the retail market. The company, backed by oil giant T. Boone Pickens, is the first commercial distributor of biogas for cars, trucks and buses. There are 35 public Clean Energy stations in California selling the fuel,......read more

White House Plans Methane Crackdown

read
New strategy on natural gas pollution could be unveiled before the end of the month

Natural gas, a key component of the Obama administration's plan for American energy independence, is highly problematic in terms of climate change. Though it has significant less carbon emissions than either coal or oil, natural gas fields "leak" methane into the atmosphere -- and methane is a potent greenhouse gas. Now key Obama advisors have revealed a government-wide strategy aimed at cutting......read more
