Americans are using less energy by staying at home
Americans are using less energy -- paradoxically, by spending more time indoors, according to a new study in the journal Joule. But researchers point out that keeping more lights on was offset by lifestyle changes that kept people inside instead of roaming around offices and retail stores -- like, say, online shopping and working from home. Despite energy consumption worldwide increasing every year, this slight uptick in American hermitage reduced national energy demand by 1.8 percent over a year.
Companies will use AI to stamp out electricity theft
Switching to efficient artificial intelligence systems has already saved Google a ton of money on its energy bills. And, it seems machine learning may also pose monetary benefits (of a different kind) for electricity providers. With power theft costing the industry roughly $96 billion in losses per year, companies could start looking to AI to help identify pilferers.
Microsoft deliberately wasted energy at data center to avoid fine, says NY Times
Microsoft's desire to avoid a fine combined with a power company's strict electricity usage rules resulted in the software giant deliberately wasting millions of watts of power, according to the New York Times. Redmond's Quincy data center, which houses Bing, Hotmail and other cloud-based servers, had an agreement in place with a Washington state utility containing clauses which imposed penalties for under-consumption of electricity. A $210,000 fine was levied last year, since the facility was well below its power-use target, which prompted Microsoft to deliberately burn $70,000 worth of electricity in three days "in a commercially unproductive manner" to avoid it, according to its own documents. The utility board capitulated and reduced the amend to $60k, but the messy situation seems a far cry from Redmond's pledge to become carbon neutral by this summer. [Image credit: New York Times]
Inhabitat's Week in Green: 'Plantscraper' vertical farm, new wave energy and a battery-powered iPhone case
Each week our friends at Inhabitat recap the week's most interesting green developments and clean tech news for us -- it's the Week in Green. Groundbreaking green architecture burst into life in Sweden this week as Inhabitat reported that Plantagon began construction on the world's first 'Plantscraper' vertical farm. We also marveled at artist Yayoi Kusama's dazzling Infinity Mirror Room, which shines with the reflections of thousands of LEDs, and we shared the bubbly modular AMPS living wall system. Meanwhile, the MoMA PS1 Young Architects Program announced that HWKN's bright blue spiky sea-urchin shaped pavilion will be popping up this summer, PinkCloud.DK unveiled plans to transform oil refineries into giant energy positive communities and the UK granted planning commission for its first amphibious house.We also showcased several amazing applications for LEGO bricks this week: a NYC apartment renovated with 20,000 plastic bricks, a gigantic LEGO-inspired church in the Netherlands and a remarkable fully articulated prosthetic LEGO arm. Speaking of next-gen prosthetics, this week Israeli scientists demoed a real-life "Star Trek" VISOR that enables the blind to see, and Nike took the wraps off a prosthetic running sole for amputee triathlete Sarah Reinertsen.This also marked a heated week for energy news as solar power heavyweight Sunpower sued Solarcity over stolen data, and Aquamarine Power geared up to connect its new wave energy generator to the UK's national grid. We also got ready for rough days ahead with the waterproof, armageddon-ready, solar-charged, battery-powered iPhone case, and we got things cooking with Biolite's brilliant new camping stove, which converts waste heat into electricity for USB gadgets. Last but not least, we were wowed by several amazing new applications for discarded tech: Sean Avery's astounding animal sculptures made from shattered CDs and Paola Mirai's elegant jewelry fashioned out of discarded computer circuits.
Energy Star 5.3 now in effect, some chunkier TVs left out in the cold
A revamped set of Energy Star requirements went into effect last week, much to the chagrin of plus-sized plasma TVs everywhere. Under the new specification (Version 5.3), sets bearing that vaunted blue sticker will have to be, on average, about 40 percent more energy efficient than standard models, while larger displays will be held to even stricter requirements. The latest iteration also calls for qualifying TVs to adhere to a "hard cap" of 108 watts (irrespective of size), essentially disqualifying any plasmas at least 50-inches in size, and any larger, non-LED-backlit LCDs. Among those sets that qualified for certification under Version 4.2, a full 14 percent consume more than 108 watts (mostly 2010 models), and only three are LED LCD-based (including Samsung's UN65D8000). Some newly disqualified 2011 models, however, may still bear blue stickers, due to Energy Star's ongoing transition process. "With the intention of seeing products that meet the newest requirements on retail shelves when 5.3 takes effect, EPA halted certification of new TVs that met the 4.2 requirements (but not the 5.3 requirements) as of May 31, 2011," Energy Star product manager Katherine Kaplan explained to CNET. "All new products certified since May 31 meet the 5.3 requirements. A product newly manufactured and certified in June had to meet the 5.3 requirements to be labeled."

Google details its carbon footprint in new report, makes you think twice about Rickrolling someone
The folks in Mountain View have always been obsessed with performance, but until now, Google had never come clean with the nitty-gritty surrounding power usage. A new report published by the company tells all, revealing that the search giant emits 1.5 million tons of carbon annually; a figure roughly on par with the UN's operational footprint, or slightly more than the amount produced by the entire country of Laos. The docket also breaks down the carbon emissions by activity, too: individual searches yield 0.2g, ten minutes of YouTube emits 1g and the average Gmail user produces 1.2kg of CO2 over a year -- which on average equates to a grand total of 1.46kg of CO2 per plebe across its properties. According to Google, that's a figure that would have been higher had it not custom designed its data centers, achieving a fifty percent reduction in energy usage versus the industry average. Plenty of infographical delight awaits you at the source below.
Report: data centers accounted for just 1 to 1.5 percent of electricity use last year, Google claims less than 1 percent of that
You'd think, watching companies like Apple break ground on sprawling data centers, that the number of servers powering our untethered lives was on the rise. In a different decade, you might have been right. But not this one. According to a study prepared at the request of The New York Times, the number of servers in use has declined "significantly" since 2005. That's mostly because of the financial crisis of 2008, says lead researcher Jonathan G. Koomey of Stanford University, but we also can't discount the effect of more efficient technologies. What's more, he says, servers worldwide consume less energy than you might have guessed: they accounted for somewhere between 1 and 1.5 percent of global electricity use in 2010. And while Google, the king of cloud computing, has been cagey about revealing just how many servers house its treasure trove of data, the company said that of that 1 to 1.5 percent, it accounted for less than 1 percent -- meaning, just a hundredth of a percent of all the electricity consumed last year. All told, data centers' energy consumption has risen 56 percent since 2005 -- a far cry from the EPAs 2007 prediction that this figure would double by 2010, with annual costs ballooning to $7.4 billion. Then again, this slower-than-expected growth could well be temporary. Though Koomey can't specify to what extent the financial crisis and technological advancements are to blame, he insists, broadly speaking, that we're primarily seeing fallout from the economic slowdown -- a stay of execution, of sorts, for those of us rooting for energy conservation.
EnerJ power-saving system prioritizes CPU voltage, may reduce energy consumption by 90 percent
It takes a lot of energy for computing systems or data centers to patch up critical errors, but what if we devoted less power to fixing less urgent issues? That's the basic idea behind EnerJ -- a new power-saving system that could cut a chip's energy consumption by 90 percent, simply by prioritizing critical problems over those that are less threatening. Unlike, say, liquid cooling techniques, the University of Washington's framework focuses exclusively on the programming side of the equation and revolves around two interlocking pieces of code: one that handles crucial, precision-based tasks (e.g., password encryption), and another designed to deal with processes that can continue to function, even when facing small errors. The system's software would separate the two codes, meaning that energy from one section of the chip would never be used to fix a major problem that the other should address, while allowing engineers to more efficiently allocate voltage to each region. The system has already cut energy usage by up to 50 percent in lab simulations, but researchers think the 90 percent threshold is well within their reach, with computer engineering professor Luis Ceze (pictured above) predicting that the system may even be able to increase battery life by a factor of ten. The team is hoping to release EnerJ as an open-source tool this summer, but for now, you can find more information in the PR after the break.
Earth Hour 2011 starts at 8:30PM your local time, wants you to switch off for a bit
In what has become an annual tradition now, the WWF's Earth Hour is presently sweeping across the globe, getting people to switch off non-essential lights and appliances for a sixty-minute kindness to Ma Earth and her finite energy resources. All you'll need to do to participate is power down the old World of Warcraft questing station, turn the TV off, and maybe take a walk outside so your lights don't have to be on, starting at 8:30PM tonight. Half the world's already done its bit and it's now coming around to those in the UK, Portugal and Western African countries to do the same. Will you be part of it?
4Home, Marvell partner for energy monitoring plug computer
If you asked Intel what this is, the company would tell you it's an experimental power sensor; if you asked a storage guru, they'd ID it as the PogoPlug. Truth be told, it's a miniature Linux computer designed by Marvell -- who's apparently decided to beat Intel at the former function. Through a partnership with 4Home, Marvell's latest 2GHz SheevaPlug will become a smart meter that measures power consumption right from the outlet, ostensibly allowing you to figure out which blasted light the kids left on this time without shoving a pricey home automation kit into your walls. No word on how much it'll cost to keep tabs on your energy bill or when you'll be able to do it, but we'll ask those important questions and more when we see the device for ourselves later this week. PR after the break.
Intel reaches for the 'smartphone zone' with Moorestown-based Atom Z6, comes up shorthanded
We've seen the future of Intel's mobile platform, and it isn't all roses and sunshine. Three years after the chipmaker told us Moorestown would reduce Atom's energy consumption by a factor of 20, company execs told us earlier today that they've more than reached that goal with the new Z6xx series. Problem is, in the smartphone realm Intel's competitors haven't been sitting idle; according to one of Chipzilla's cantaloupe-and-magenta bar charts, it seems the company has merely caught up in terms of battery life. That's not to say the chips aren't worlds better than previous Atoms -- Intel sees 1.5GHz smartphone processors that slay Snapdragons and up to 1.9GHz in a tablet PC variety -- but 5 hours of web browsing is most decidedly not the 24 hours of productivity Intel previously promised. Besides, who knows: Qualcomm also has a 1.5GHz SoC in the works, though it may not be available by the time Intel's chips ship in the second half of the year. None of this is to say that Intel won't continue to dominate in the netbook marketplace -- we shudder to think at the potential when combining a nice, chunky battery with Intel's nearly leakproof new chips, and perhaps a small serving of switchable graphics while we're at it. But without a single new MID or smartphone to show us this morning -- Aava Mobile and OpenPeak's offerings seemed unchanged from our previous encounters -- we're not sure if the company's other mobile ambitions have any sway. Not technical enough of a discussion for you? Peruse our gallery for the nitty-gritty. %Gallery-92318%
Intel's experimental sensor analyzes appliance power consumption from single outlet
It's pretty much set in silicon -- in the future, you will monitor your home power consumption, and perhaps even enjoy doing so. Futuristic touchscreen panels and free monitoring software abound, each designed to reward you with a warm, fuzzy Captain Planet feeling and a reduced energy bill when you finally turn off that blasted light. Thing is, unless you've got a home automation system, you won't know which switch to flip. Intel wants to change that with a new wireless sensor that can identify each individual appliance in your house by their unique electrical signal, just by plugging into a single outlet in your house. The reportedly low-cost sensor works by simply recognizing voltage drop patterns when devices are turned on and off, and doesn't require special appliances to function; Intel demonstrated it on a standard toaster, microwave and fridge in Beijing this week. Demonstrate your supreme demand for this "why didn't I think of that" idea by directing traffic to our source link -- you can jump to 20:10 to see the sensor in action. Update: Come to think of it, that looks just like a wireless version of Marvell's SheevaPlug.
Earth Hour starts at 8.30PM tonight, asks for sixty minutes of natural living
Time to don your eco-warrior armor, strap on your nature-loving helmet, and flick that big old... light switch. Yes, in honor of the WWF's Earth Hour, countries around the globe are tonight switching off non-essential lights and appliances for sixty minutes, with highlights including Big Ben, the Eiffel Tower, the Burj Khalifa, and the Empire State Building all going dark in the hope of helping the planet stay green. Timed for 8.30pm your local time, this unorthodox event has already commenced with Australia, New Zealand, China and others doing their bit -- videos after the break -- and is just now hitting Eastern European borders. So, fellow earthlings, will you be among the projected one billion souls that go au naturel for an hour tonight? [Thanks, Pavel]
EnergyStar program certifies 'gasoline-powered alarm,' other imaginary abominations
It'd be pretty difficult for you to reach Engadget without having seen the EnergyStar logo on something along your way here. Whether it was as part of your motherboard's bootup sequence or on the box of your new TFT monitor, EnergyStar certification has become a de facto standard for most electronics being manufactured nowadays. What you might not have known -- but probably could have guessed -- is that the process for obtaining that sticker is far from bulletproof. The American Government Accountability Office has recently done a bit of spy work by putting forward imaginary products and false claims to the validating authority, and regrettably found its bogus items "mostly approved without a challenge." The auditors' conclusion was that the program is "highly vulnerable to fraud," and the stuff they've had certified would seem to corroborate that verdict. Hit up the Times article for the full story of governmental incompetence while the Department of Energy -- the body responsible for running the program -- tries to get its act straightened out. [Thanks, Adam]
NYT: Google's PowerMeter to let users track electricity usage
The New York Times is reporting Google will announce a free web service tomorrow called PowerMeter that'll let users track energy consumption in their homes or business, provided there's a means to upload the data. That part of the equation's gonna be up to other companies to create compatible devices, and while no manufacturing partners have been named, we'd suspect strange bedfellow GE will probably jump aboard pretty quickly. The service is expected to roll out in the next few months. Ready to give the boys in Mountain View even more access to your life?Update: The official site has launched. According to the FAQ, PowerMeter is currently in closed beta. There's also a video about the program, which you can peep after the break.
Intel's dual-core Atom 330 reviewed in desktop guise
Intel's Atom processor and the netbook are the silicon equivalent of Lindsay Lohan and Samantha Ronson; they're inseparable. Naturally we can't wait for the dual-core Atom 330 to cozy up to the next generation of economical portables, but have to wait a bit as it's being soldered exclusively into tiny desktops at the moment, like the one tech site The Guru of 3D just ran through a series of benchmarks. The posted results could have been interesting had they compared its performance to the single-core Atom 230 rather than AMD's (relatively) heavy-hitting Athlon 4850 X2 and Phenom 9850 -- not exactly apples to apples. We'll just have to assume it's roughly twice as fast on the right apps, all that for only twice the power consumption. That's still only a measly 8-watts! [Via The Inquirer]
AMD taking on Atom with Ultra-Value Client line
Another week, another AMD leak about taking it directly to Intel's minimalist Atom. No, not with Bobcat, but with the new Athlon Ultra-Value Client (UVC) series. AMD is targeting the 230 with its 2650e, a single-core 1.6 GHz chip, and the 330 with its 3250e dual-core 1.5 GHz processor. Both have 512KB of cache per-core, matching the competition, but are rated at 15- and 22-watts respectively, much higher than the Atom's miserly 4-watts. It's unclear if that rating is current for just the CPU or the matching 740 chipset as well, but given the fact that AMD's Athlon 64 2000+ is already quite frugal we wouldn't be surprised if it were for the package. There's no mention of price, and right now these chips are just for desktop OEMs, but laptop versions are said to be in the works and could be quite popular amongst the netbook crowd -- if they're cheap enough. 1.2GHz of Turon can do wonders, and we're hoping for even better from 1.6. [Thanks, Luiz H]
Athlon 64 2000+ at 8-watts outperforms, draws less energy than Atom
AMD's going through some rough times, no doubt about it, but for fanboys of the CPU maker (wait, do CPU fanboys still exist?) here's your feel-good story of the year. The always-thorough Tom's Hardware has pit Intel's 1.6GHz Atom 230 processor against AMD's Athlon 64 2000+, and the results just might surprise you. The 1GHz Athlon (with a core voltage of 0.90 volts and a power draw of just 8 watts) managed to best the aforementioned Atom in both energy consumption and processing power tests. The gurus at Tom's credited the more modern 790G platform and the highly efficient K8 architecture as big players in the Athlon's strong showing, finally deeming said chip "more economical, faster and quieter" than the Atom. We know you're in disbelief -- good thing there are 14 pages of proof waiting in the read link.[Thanks, Carl]
NEC develops M2 LSI chip to conserve energy in cellphones
Hot on the heels of a snazzy new CMOS sensor and newfangled plastics, NEC's engineers are cranking out yet another innovation to make our next phone a lot more useful (for a whole lot longer). The M2 system LSI chip can purportedly "drastically cut the energy used by a cellular phone" by halving the energy needed by each element on the chip. Notably, the firm has suggested that a cellphone battery currently lasting seven hours would be able to maintain that life even if "twice the power is required for high-speed telecommunications." A host of sophisticated technologies and software regulations are behind all the energy conserving magic, but the news you care about is that NEC plans to start shipping samples of the ¥5,000 ($41) device in the very near future, and it should hit a variety of 3G handsets by the year's end.
