  • Study Shows People Are Clueless About Energy Savings – Here's What Actually Works.

    Quick, name one of the best things you can do to save energy at home. If you said “turning off the lights,” you’d be wrong. But you are not alone, most Americans say the same thing. A new survey shows most people have misconceptions about what works best to save energy. Keeping lights off isn’t a bad idea in itself, but it has significantly less impact than swapping… Read More

  • Alternative Energy: A Guide To Greening Your Home

    Alternative energy is a growing market, and though many states offer tax credits, rebates, and other incentives to promote clean energy, it can still prove to be an expensive proposition. It generally also requires plugging your energy source into the grid so you’re not left in the dark when the wind calms or the sun lingers behind clouds. Here is a roundup of solutions that can help power… Read More

  • The Heat Is On: There Is Plenty Of Geothermal Energy Underground, We Just Need To Get To It

    Most green technologies gather energy above ground, but like Jules Verne, we want to take you on A Journey to the Center of the Earth. Alright, not even close to the center, but deep down nonetheless, where naturally occurring hot water can be turned into clean energy above ground. It is estimated that the amount of heat within 30,000 feet below the earth’s surface holds potentially… Read More

  • China now the world's top energy consumer (but the U.S. has become more energy efficient)

    Is there a green movement in China? Maybe there ought to be, considering the numbers that have just come out. China is now the planet’s number one consumer of energy, overtaking the U.S. in the process. But at the same time, the U.S. has improved its energy efficient more so than China, meaning that the U.S. can get the same amount of work done while consuming less, say, coal or oil. Read More

  • Solar Impulse, the solar-powered airplane, tries to fly 24 hours

    A solar-powered airplane, named the Solar Impulse, means to prove, once and for all, that harnessing the energy of the Sun is a good and practical idea. I mean, why would we try to capture some of the energy put out by a completely free nuclear reactor hanging in the sky? The plane took off from Switzerland a little bit ago, and will try to fly for 24 hours without stopping. Here’s… Read More

  • CleanTech Venture Investments Total $2 Billion In Q2, Exits Reach More Than $8 Billion

The Arlington, VA based company’s 10,000 square foot office in San Francisco’s South Park neighborhood will have room for between 75 and 100 employees, a large part of which will be engineers. “We signed a two-year sublease… Read More

  • New solar cells printed on paper

    Everyone loves the idea of solar energy. The three big challenges are that solar cells are expensive to produce, they’re not very efficient, and you need some means to store the energy collected. I’d heard of solar shingles before, which are basically roofing shingles with solar cells in them, but now word is coming out of solar cells printed on paper. As usual, the technology is… Read More

  • Aquafairy FC Stick: Efficient mini fuel cell for gadget fans (video)

    Fuel cells are on their way into the mainstream, even though the commercially available models are still pretty pricey. But there are companies like Kyoto-based Aquafairy [JP], for example, preparing affordable fuel cells, too. Their four new fuel cells are intended to make gadget fans in particular happy: the micro FC Stick (0.8W), the FC-Stick (2W), the FC-Cube (3W) and the FC-Cube Dual (6W). Read More

    John Doerr On Bloom Energy Launch: "This Is Like The Google IPO"

    After eight years of operating in quasi-stealth, Bloom Energy came out with a bang today at an event in Silicon Valley attended by Arnold Schwarzenegger, Colin Powell, Larry Page, John Doerr, and executives from eBay, Walmart, Coca-Cola, and FedEx. All of the big-name companies, including Google, are beta customers of Bloom’s distributed energy fuel cell technology (which was the subject… Read More

  • Walking and jumping and generating energy, oh my

    Sometimes I’m assigned stories and I’m like, “Really? If you insist, boss.” This is one of those stories. It’s a collection of sidewalks, or derivatives, that “work while you wait.” Yup. Read More

  • Steorn to show off overunity Saturday: Where will you be when we discover limitless free energy?

    This Saturday I’m probably going to wake up a little later (we have kids so that means like 8am) and maybe make some breakfast. Then maybe we’ll go for a walk in town here or the wife will take the kids to the Children’s Museum and I’ll do some writing. Then I’ll eat lunch with the fam, maybe watch a movie (probably some Disney stuff). The kids will eat dinner… Read More

  • RCA Airnergy promises usable power generated from Wi-Fi signals. Possible?

    I’m a simple man. I understand certain things. How ambient Wi-Fi signals could be converted into enough energy to charge a BlackBerry is something I do NOT understand. However, RCA not only showed off the technology at CES but the device will apparently be available by the summer and it’ll only cost $40. Read More

  • Privacy versus power: smart grids are the new battlefield

    I think we can all agree that protecting our own personal privacy is a generally good idea. There are an enormous number of ways that our privacy can be encroached in a given day. Some of them are “for our own good”, or “just the cost of doing business” in the modern age. Some of the ways our privacy may be violated are extremely esoteric and not very likely (hard… Read More

  • LED lightbulb puts out equivalent of 60 watt bulb, uses only 6 watts

    Oh man, I thought those compact florescent lightbulbs (CFLs) were expensive at around five bucks a pop. Say hello to the $40 LED light bulb — and that’s an introductory price. It’ll apparently cost $50 later. Read More

  • Microsoft Hohm available today

    Microsoft’s new tool – Hohm – is supposed to help you save energy and money. While I signed up for the beta unfortunately I can’t try this odd named thing since I live in Europe. This is why I need your feedback on how Hohm works, so be kind and leave comments with your opinions. Or don’t. Read More

  • Energy consumption will triple by 2030 if electronics' efficiency doesn't increase

    Yes, your refrigerator, washer, and dryer may be Energy Star certified, but any good you’re doing is offset by your DVD player, TV and computer. That’s the simplified version of a new International Energy Agency report that says white goods—refrigerator, washing machines, etc.—are a lot more energy efficient than they used to be, but that consumer… Read More

  • PG&E wants to harvest solar energy from space

    Everyone loves solar power, right? It’s basically an infinitely renewable resource — at least for as long as any of us care — and it’s free. FREE! Why, I remember making and using solar powered hot dog cookers back in Boy Scouts; and people a lot smarter than me have been planning things far more sophisticated than a hot dog cooker. Take Solaren, for example. Read More
