    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 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

    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 electronics—computers, TVs… Read More

  • PG&E wants to harvest solar energy from space

    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. They're hoping to work with Pacific… Read More

  • Leaving computers on all the time wastes $2.8 billion per year in the US

    Leaving computers on all the time wastes $2.8 billion per year in the US

    Oops. Apparently all the computers in the US that are rarely, if ever, shut down at night account for almost $3 billion in wasted energy costs and “may emit up to 20 million tons of carbon dioxide.” Read More

  • Kimberlina solar plant in California generates electricity like it's its job

    Kimberlina solar plant in California generates electricity like it's its job

    Asura just opened the first-of-its-kind thermal energy plant in California, which should generate enough electricity to power some 3,500 homes. The best part is that this plant, which is named Kimberlina, is merely a proof of concept of sorts— the real plant, to be constructed by 2010, will generate enough electricity to power, like, 120,000 homes. The idea is dead simple: you’ve got… Read More

    Panasonic develops world's smallest notebook fuel cell

    Panasonic today announced [JP] it developed the world’s smallest fuel cell for use in notebooks, reducing the size of its predecessor by 50%. The new model is sized at 270cc, which makes it as small as existing lithium ion batteries used in notebooks currently on the market. Panasonic says the fuel cell will be positioned at the underside of notebooks and provides about 20 hours of power… Read More

  • Car cigarette lighter with four USB connections

    Car cigarette lighter with four USB connections

    Yes, yes, a thousand times, yes. For $22.99 you can charge four USB-powered devices plus another regular DC-powered device in your car. It’s only $22.99 – roughly the cost of one or two device-specific DC adapters. Since just about everything charges via USB nowadays, this is a pretty obvious choice for any gadget fiend who spends a lot of time on the road. Car Charger with 4 USB Ports… Read More

  • Windmills are the future of energy generation, apparently

    Windmills are the future of energy generation, apparently

    Some feel-good news for your enjoyment, this time about how wind power can save the planet, or something. It seems that for the low, low price of less than two cents per day, the U.S. would be able to generate something like 300 gigawatts of electricity using windmills. That translates to an 11 percent reduction in natural gas consumption, saving 4 trillion gallons of water every year, and a 25… Read More

  • Greening the geek house

    Greening the geek house

    Go downstairs and check out your power meter. It’s probably spinning frantically. Why? Because you’re blowing electricity out of your home theatre set-up and home office like a fiend. Don’t worry: I’m doing it to. We all are. It’s the cost of staying online and entertained these days and, sometimes when I’m in the basement, I kind of get a twinge of… Read More
