Amanda Sutton looks over a wheat field in northern Colorado and sees a potential project that could help curb greenhouse gas emissions linked to global warming.
Admit it: we all wondered just what Sarah Palin would turn her time and talents to after she announced her resignation from the Alaska governor’s job, and now she’s given what looks like an answer. In an op-ed column in The Washington Post, Palin took a swipe at Washington insiders and the mainstream media for ignoring the economy, and then tipped her hand.
America's social and religious conservatives are turning up the heat as they galvanize heartland opposition against the latest example of President Barack Obama-inspired "socialism" -- a climate change bill that aims to reduce fossil fuel emissions, which most scientists have linked to climate change.
A “gold-rush-like” buzz has spread across Germany in the last week over tentative plans to invest the staggering sum of 400 billion euros to harvest solar power in the Sahara for energy users across Europe and northern Africa. Even though European and Mediterranean Union leaders have been exploring and studying for several years the idea of using concentrated solar power (CSP), the Desertec proposition suddenly captivated the public’s attention a week ago when German reinsurer Munich Re announced it had invited blue chip German companies such as Deutsche Bank, Siemens and several major utilities to a July 13 meeting on the project. The 20 companies aim to sign a memorandum of understanding to found the Desertec Industrial Initiative that could be supplying 15 percent of Europe’s electricity in the decades ahead.

Wal-Mart, which helped promote the adoption of those funny-looking "green" lightbulbs, is making more room in its Sam's Club warehouse stores for environmentally friendly products -- including a water-saving toilet that has one button for flushing liquids and another for flushing solids.
Shares in Pacific Ethanol lost almost half their value in morning trading after the biggest West Coast-based producer and marketer of ethanol announced that it had put its production facilities in California, Oregon and Idaho into Chapter 11 bankruptcy.
But General Electric thinks its new battery technology, based on sodium, could radically speed up that process.
“The way the roadmap has been laid out as I’ve seen it is a lot of evolutionary steps,” with technological development taking years if not decades to replace traditional gasoline powered cars with hybrids, followed by plug-in hybrids, followed by pure electric vehicles said Glen Merfeld, who runs the chemical energy lab at GE’s global research center in Niskayuna, New York.
The reason for that long timeframe is that current battery technology limits the range of a car that draws its power solely from an internal battery.
“The sodium battery is potentially disruptive to that evolutionary look,” Merfeld said. The technology that we are commercializing will solve some of those problems.”
GE on Tuesday said it plans to build a new factory outside Albany, New York, where it will initially focus on producing sodium-metal halide batteries for railroad locomotives. That technology differs from the lithium-ion batteries being developed for the next generation of hybrid autos in that it is better suited for releasing small amounts of energy over time, rather than a lot at once.
Eventually, by pairing the sodium battery with a lithium-ion one, such as those made by A123 Systems, which GE owns a stake in, the company could design a power train for an all-electric car that would allow a range of hundreds of miles and cost 30 to 40 percent less than a single-battery power train, Merfeld said.
“You’d probably want to start with larger (vehicles) because that’s where you need to store more energy than in the smaller ones,” added Mark Little, a GE senior vice president who runs its research center. “We could imagine a day where you could go to the future and have a small lithium-ion system for the power side and a larger sodium battery for the energy side. But that will take some time to get to.”
