Op-Ed: Recently we added some new sites to our link library. The total is up to 49 but the three newest are off the beaten path: the Athena Institute, GreenDrinks, and WattWatt. (We truly hope to refer you to sites that are useful, not just a million and one blogs and such.
Energy News: America's demand for clean energy will beat supply by 37 percent in 2010, the National Renewable Energy Lab will report next week -- that's according to USA Today. They also explain how half of the states require certain percentages of their providers' power to come from clean energy
Energy News: CNN posted a very solid overview story about the state of solar power. The technology, if we lived in a proverbial vacuum, can already provide all the world's energy needs by installing panels in a small corner of the Sahara. But in the real world, cost and security are
Energy News: More than a third of enterprise CIOs don't monitor their corporate energy use, according to an Economist Intelligence Unit report, commissioned by IBM. "Although concerns about energy efficiency and global warming are now high on the political agenda, the spotlight

Energy News: DNA from salmon -- specifically, from the fish's sperm -- makes an excellent choice for building extra-bright, biodegradeable light-emitting diodes, researchers at the University of California / Riverside found. It sounds fishy but it's true. “DNA has certain optical
Op-Ed: There's a blog post over at CNET about an E85 Dodge Viper which is breaking speed records. They wrote, "More than doubling the horsepower probably had a big effect on the performance of the car, but the extra octane can't hurt. Ethanol also cuts down on the greenhouse gases from the tailpipe."
Energy News: Two interesting stories today from eWeek: first, the Green Grid member companies signed a Department of Energy agreement for data center metrics; second, coverage of Energy Star director Andrew Fanara's declaration that volume servers are so obviously bad for the green agenda.
Op-Ed: The full story isn't clear here, but it looks like a government crackdown on the very popular Alameda County Computer Recycling Center. For readers not in the Silicon Valley area, I can personally attest that ACCRC is a well-run, well-supported organization which does a valuable community service. So why would an EPA inspector
Productive Product: Let's start by clarifying a vital point: this story is about solar power adapters for conventional PCs, not about "solar-powered PCs" per se. You don't actually get a solar panel slapped to the side of your tower case; you get 86 pounds of schleppability. But you also get to help save the planet and circumvent your local
Energy News: According to U.S. News & World Report, "Minnesota Gov. Tim Pawlenty, the new chair of the National Governors Association, was in Washington this week to argue that state governments should be a driving force in reducing the nation's dependence on foreign oil and in fighting greenhouse
Energy News: There's a big dose of clean-energy straight talk over at Forbes.com from physicist and investor Mark Mills. He says there is plenty of room for smart investments into alternative energies, because there wasn't much of a bubble in the first place, nor was there a bubble 30 years ago when many of the same technologies were going to save us from
Productive Products: Human harvesting. Algae pools. Wave power. Artificial tornados. Super kites. Tesla coils. The list reads like a high-tech version of the plagues that freed Moses' people in Egypt, but will these alternative energy concepts succeed or have the proverbial sea crash down on them? "True, many of the kookier-sounding concepts are still in deep development within large corporations, universities, and
Energy News: "Los Angeles and Pittsburgh provide examples of what to do — and not to do — about China's severe air pollution in the face of surging energy use from rapid economic growth," according to this AP report of U.S. and Chinese scientists' joint research. They added: "The study released Thursday compared the world's two biggest energy consumers
