Coal Prices May Rise Sooner Than Anyone Expects As Global Reserves Revised Downward

Coal mining in Germany, photo: Bert Kaufmann / Creative Commons We’ve written about how the world’s recoverable coal reserves may be much less than commonly believed (and touted by politicians and coal producers) for a while now; here’s another take on it from Richard Heinberg and David Fridley of the Post Carbon Institute… Read the full story on TreeHugger

The Downside of Heat Cogeneration at Coal Power Plants

A coal plant in China. Photo: Wikipedia , CC Don’t Turn Off the Heat Please Both the US and China have many coal plants (producing about 45% of the power in the US and 75% in China). One difference is that in China, it is more common for the waste heat from those power plants to be recovered and used to heat local residential buildings or for industrial purposes. On the face of it, this is a good thing, but as Kevin Bullis points out , this also… Read the full story on TreeHugger

Valley Devastated by Coal Ash Waste (Video)

Photo: Richard Webb , Geograph, CC Most Americans are hardly aware of what coal ash (also commonly called fly ash) is — though plenty became more familiar with the stuff around two years ago when a massive slurry of the stuff was unleashed upon Tennessee . The often toxic byproduct of burning coal for electricity, fly ash is usually captured from the chimneys of power plants. Then, it’s stored in containment sites — or dumped. The following video documents the impact that coal ash… Read the full story on TreeHugger

New Map Shows Air Pollution Throughout the World

Image via NASA Scientists have long known about the life-threatening impact of air pollution — but up until now, tracking it globally with any accuracy had been out of reach. With new satellite-based imaging, however, researchers are getting their first peek at how particulate matter is distributed around the world, and in places where air pollution had been difficult to measure with any accuracy before — an important step towards … Read the full story on TreeHugger

World’s Largest Mining Company: We Must Move Away from Coal

Photo via Cleantechnica While we’ve received a healthy influx of signs that the world’s heavyweights aren’t planning on diversifying their energy portfolios to any radical degree in the near future — China building a submersible to dive 7,000 meters underwater to explore for oil among them — there are still reasons yet to be optimistic. Take this for example: the CEO of the largest mining company in the world, Australia’s BHP, ha… Read the full story on TreeHugger

Canada’s Lost Salmon Return in Droves

Image credit: Hemera/Thinkstock Every year, sockeye salmon return to the rivers of western Canada to make their arduous upstream journey to calmer spawning grounds. It is a seasonal touchstone that signifies the approaching end of summer, one that has been observed for centuries. The only problem is that some years, like in 2009, the salmon don’t return….

US Govt May Back 9 GW of Coal Power Plants in India & South Africa, When It Should Support Renewables

photo: Duncan Harris via flickr Despite a Congressional mandate directing the Export-Import Bank of the United States to use 10% of its 2009-2010 financing towards renewable energy project, according to a US Government Accountability Office report the Bank will fall “well short of the 10% Congressional target”–as in only spending 2% on renewables. In fact right now in may back nearly 9 gigawatts of humungous coal-fired power plants in India and South Africa…. Read the full story on TreeHugger

Does the "Utility Only" Cap and Trade Pass Muster?

Photo via the Blind Eye The chances of comprehensive clean energy and climate legislation passing the Senate continue to slip away as the election cycle draws nearer. ‘Moderate’ Dems fear throwing their support behind a climate bill like Kerry and Lieberman’s, since Republicans have had some success falsely labeling the bill a ‘job-killing energy tax” (never mind that the vast majority of Americans support clean energy legislation). So, a number of alternative options are being considered, such as an ‘energy only’ bill, and a ‘utility only’ cap and trade bill — a bi… Read the full story on TreeHugger

The Many Faces of American Power (Slideshow)

Image credit: Mitch Epstein, American Power Across the country, billboards are springing up. They feature an image that is arresting—smoke spewing from a coal plant, a massive power plant behind a school, or the hulking industrial frame of an oil refinery—and a simple question written in plain letters. “What is American Power?” Taken from photographer Mitch Epstein’s book American Power , the question is a starting point for a much deeper exploration—and the path it r… Read the full story on TreeHugger
