Bill Gates is launching a multibillion-dollar clean energy fund
Microsoft co-founder Bill Gates is set to reveal a massive clean energy project on Monday, during the first day of the United Nations climate change summit in Paris. According to Reuters, which originally reported the news, the French government has confirmed that the ex-CEO-turned-philanthropist will launch the Clean Tech Initiative, a push to commit countries to double their budgets on clean energy tech research and developments by 2020. But Gates won't be working on this multibillion dollar fund alone: The US, Australia, Canada, France, India, Indonesia, Norway, Saudi Arabia and South Korea will all be backing the plan, a person familiar with the matter told Reuters.

Apple to build a 20-megawatt solar farm for its Reno, Nevada data center
Apple's Reno, Nevada data center might be a lot greener in the next few years -- according to GigaOm, the company plans to build a 137 acre solar farm right next to it. The Nevada complex will reportedly generate between 18 and 20 megawatts of power similar to Apple's two arrays in North Carolina, but GigaOm says it will use a different kind of technology. Instead of a standard farm of solar panels, it will include mirrors that concentrate the sun's rays on each one up to seven times, increasing the amount of energy produced. In a statement sent to the publication, Cupertino revealed that the facility will not only provide electricity for the data center, but also supply energy to the local grid. Solar company SunPower will work on the array's engineering and construction, but until it's operational (which could be a while), Apple will depend on geothermal energy generated by local plants.

3D, light-trapping solar cells successfully fabricated by Solar3D
Solar3D probably isn't a company you're particularly familiar with... at least not yet. The California-based manufacturer has just successfully fabricated a three dimensional solar panel that traps sun light in nano-scale wells on a silicon wafer. Perhaps most exciting, the prototype panel was built using off-the-shelf tech from Panasonic, meaning that the price of mass production shouldn't be prohibitively high. More testing is needed, but the resulting panels should be up to 50 percent more efficient than current generation 2D ones. For a few more details, check out The PR after the break.
Inhabitat's Week in Green: Sky City One, remote-controlled light bulbs and the Zero-G Olympic Games
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. It took five years to build the Burj Khalifa, the world's tallest building -- but this week Inhabitat reported that Chinese company BSB plans to build the next world's tallest tower in an astounding 90 days. Dubbed Sky City One, the soaring spire will be constructed using prefab building techniques in record time. In other architecture news, Singapore officially unveiled its lush, sprawling Gardens by the Bay in advance of their opening next week -- and the stars of the show are these spectacular solar-powered supertrees that harvest rainwater and light up the night. We also took a peek inside a bomb-shelter-turned-nightclub that is blowing up in Beijing, and several internet titans unveiled new building projects -- Twitter moved into a new green-roofed headquarters in San Francisco and eBay announced plans to power its flagship data center with a Bloom Energy fuel cell farm.
Amazon becomes the latest retailer to sell the trendy Nest Learning Thermostat
Frankly, we all knew it was only a matter of time before the renowned online retailer, Amazon, would start offering the trendiest thermostat known to man. Joining the likes of Apple, Lowe's and, naturally, Nest's official site, Amazon is the latest shop to welcome the famed Learning Thermostat onto its shelves, with availability expected as soon as tomorrow (June 8th). As for pricing, that won't be changing much, which means you'll still have to shell out $249 -- though, you could see it hit your doorstep sooner without paying extra if you have one of those fancy Prime accounts. In any case, folks looking to grab one of these notorious Nest thermos can do so from either of the source links below.
Apple Store now selling Nest Thermostat: automated toastiness to cost $250
Apple liked it so much, it's decided to let the Nest Thermostat share shelf-space in its bricks-and-mortar stores and online. Following rumors that Tony Fadell's latest project would appear at his former employer's store, it's now been confirmed with an online listing. Following some brief downtime on the Cupertino corp's retail site, the unit is set to retail for $250. Aside from sharing some design DNA, the thermostat unit can also be controlled from iPhones, iPads, iPods and Macs -- we presume that Android functionality is still there. Those that like their summers extra comfortable can hit the store link below.
USC develops printable liquid solar cells for flexible, low-cost panels
Solar cells are becoming more viable sources of energy -- and as they become more efficient, they're only getting smaller and cheaper to produce. Liquid nanocrystal cells are traditionally inefficient at converting sunlight into electricity, but by adding a synthetic ligand to help transmit currents, researchers at USC have improved their effectiveness. The advantage of these liquid solar cells? They're cheaper than single-crystal silicon wafer solutions, and they're also a shockingly minuscule four nanometers in size, meaning more than 250 billion could fit on the head of a pin. Moreover, they can be printed onto surfaces -- even plastic -- without melting. Ultimately, the goal of this research is to pave the way for ultra-flexible solar panels. However, the scientists are still experimenting with materials for constructing the nanocrystals, since the semiconductor cadmium selenide they've used thus far is too toxic for commercial use.
Amazon data center guru questions logic of Apple's solar farm
James Hamilton is a former datacenter architect for Microsoft and the current datacenter guy for Amazon. In a recent blog post, he examines solar-powered data centers which he says are "really somewhere between a bad idea and pure marketing, where the environmental impact is purely optical." As you can guess from that statement, he isn't too fond of Apple's solar farm setup in Maiden, North Carolina. Hamilton, on the one hand, applauds Apple for the solar-power installment at its North Carolina datacenter. He notes that the solar farm is the largest commercial deployment in the US at 20 megawatts, and, because of its size, has a "far better chance to work economically than other smaller installments." Though he commends Apple for its efforts, he also questions whether it's a wise move. Despite its size, Hamilton says the solar farm will provide photo voltaic power for only 4% of Apple's total estimated data center consumption. Hamilton notes that Apple cleared 171 acres of land in order to build its solar farm and wonders if this 171-acre parcel of woodlands is worth such a small portion of Apple's power needs? [Via Wired]
Nanoshells trap light for more efficient solar panels
Scientists at Stanford are hard at work trying to improve the efficiency and durability of solar panels -- two key factors that have kept the Sun from becoming a more popular source of energy. Their latest effort involves nanocrystalline-silicon, a material that has proven resilient and highly conductive, but not very good at absorbing light. Their solution, nanoshells -- hollowed out spheres of silicon that trap and recirculate light much like a whispering gallery does sound. Balls of the crystalline material are dipped in silicon, then hydrofluoric acid is used to eat way the center of the sphere, leaving a path for light to enter. The shells trap the light, allowing more of it to be absorbed, and also reduces the effect of non-optimal angles on energy production. Hit up the source for a few more details.
Samsung gets tired of neighbors watching its Transparent Smart Window, installs blinds
Sammy's transparent OLED displays may not be the freshest piece of tech at CES, but its still pretty dang awesome. We first saw Samsung's 46-inch 1920 x 1080 digitally augmented window back in March, but dropped by its CES booth for a second look. Although the touchscreen window still teases to fulfill our fevered sci-fi dreams, not much has changed -- it's still clear, it's still loaded with widgets, and it's still not anywhere near being installed in your home. Samsung told us this was still a concept device, although they did mention that the technology could be scaled down for use in military visors and heads up displays. Hit the break to see a video demo of a few new apps, including a rather slick set of digital blinds.Joe Pollicino contributed to this report.
Onyx develops 330-watt 'plug-n-play' solar panel with built-in AC outlet
Onyx's new 330-watt solar panel isn't the first to offer a "plug-n-play" solution for getting power to your gadgets, but it may be the first to include a standard US power outlet, and enough output to juice up a computer, light or any other appliance (within reason) through its built-in micro inverter. "You can literally point the panel at the sun and plug an extension cord directly into the panel for immediate power," according to the Onyx PR, which you'll find in full just past the break.
Apple to build a solar farm next to North Carolina data center
Apple is reportedly building a solar farm to provide energy for its North Carolina data center. An erosion permit granted by Catawba County, North Carolina gives Apple permission to transform 171 acres of vacant land across from the data center into a solar farm. The area will be resloped and will include multiple gravel roads that provide access to the solar panels. It's the first step in a larger plan called Project Dolphin Solar Farm A Expanded. Project Dolphin is the codename given to the construction project behind Apple's billion dollar data center. The constucton is in the early stages of planning and very little in known about the farm. Scott Millar, president of the Catawba County Economic Development Corp. and the man who helped bring Apple to the area, was not aware of the solar farm plans. He did not know Apple filed for a permit until the Charlotte Observer brought it to his attention and said he has had "no communication" with Apple about these plans. A building permit which would contain construction details has not been filed. The only people aware of the solar farm are neighbors of the data center who are complaining about smoke from the property. Apple is burning the field to clear it and, according to residents, is producing a thick smoke that blankets the surrounding area. The burning is also driving animals out of their habitat. "I had a snake on my steps," says local resident Zelda Vosburgh, "I've seen rabbits and squirrels everywhere." It's an eco-friendly move for Apple, but don't expect to be able to say the iSun is powering your iCloud anytime soon. Most of this solar power will likely go to the office part of the building, and won't be used to power the servers. Modest estimates suggest the 170 acre solar farm would generate about 24 megawatts of power, which is far below the 40 to 100 megawatts Apple's datacenter is estimated to use.

iPod fathers unveil their next project, the Nest Learning Thermostat (hands-on)
Over the summer, we got word that a couple of unnamed ex-Apple engineers were getting ready to unveil an unnamed product, under the guise of an unnamed startup. As it turns out, that startup was Nest Labs, and those Apple alums were none other than Tony Fadell, longtime SVP of Apple's iPod division, and lead engineer Matt Rogers. And yes, the product they had to share makes fine use of a click wheel. But if you thought they'd be cooking up a next-gen music player, you'd be wrong. Instead, the pair have been designing a thermostat, of all things, dubbed the Nest. In addition to being the most stylish model ever to grace a dining room wall, it promises the kind of intelligence we've come to expect in other household appliances -- just not thermostats, per se. It'll go on sale next month for $249 in places like Best Buy, but we managed to snag an early sneak peek. Find some photos below and when you're done, join us past the break where we'll explain how it works. %Gallery-137451% %Gallery-137452%
Czech electric scooter company covers 706 miles in 24-hours, claims world record
A "racing" team for the Czech electric scooter company Akumoto, with the assistance of the energy conglomerate ČEZ , is claiming the world record for longest distance traveled by such a vehicle in 24-hours -- 706.1 miles. Over the course of the 1,136.3 kilometer trip, the slightly modified scooter used a grand total of 40.8 kWh of electricity, which costs a measly 190 Czech Korunas (about $10.35). Akumoto already has a network of charging stations across the Eastern European country, but there was no stopping to juice up. Instead pre-charged batteries were swapped in when the "tank" was empty. We just hope that there were several drivers taking turns at the handlebars -- spending a full rotation of the Earth with your rear planted on a souped-up Vespa doesn't sound particularly comfortable.
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.
Toshiba Regza 32BC3 HDTV features power saving button, destined for Japanese shores
The latest member of Toshiba Regza family of HDTVs, the 32BC3, just had it's pretty little IPS face revealed in Japan. Unlike most sets you see these days, this 32-incher sports only a 1,366 × 768 panel. But what makes the BC3 special isn't its resolution, its the ability to conserve power by dramatically dropping the brightness (supposedly with out sacrificing image quality) with just the push of a button. Pressing the power save button on the remote drops the brightness by 50-percent, press it again and it dips down 75-percent. The Regza 32BC3 will land on shelves in Japan this September for around ¥ 65,000 (about $830). And, as usual with these slightly odd sets out of the land of the rising sun, there's no word of when (if ever) this will make it state-side.
AT&T becomes the first telco to use energy-efficient Bloom Box servers, will power 11 sites in California
Remember Bloom Energy servers, those low-cost, energy-efficient fuel cells born out of a scrapped NASA project? The company made a splashy debut last year, starting with a spot on 60 Minutes and a long list of early-adopting corporate heavyweights like FedEx, Walmart, Google, Coca-Cola, Staples, and eBay. Since then, we haven't heard much from the company, but today she's back -- AT&T says it will be the first telco to use these refrigerator-sized servers to power its operations. For now, the company's planning on using the technology to run 11 sites in California, a move AT&T says will cut its carbon dioxide emissions in half and virtually eliminate SOx, NOx, and other smog-forming particles. All told, its servers should produce 62 million kWh of power annually -- once all of these servers are fully up and running sometime in the middle of next year, that is. We say good on AT&T, though we'll really be stoked when these things start lighting up more average Joe homes.
Mizzou Professor says nantenna solar sheet soaks up 90 percent of the sun's rays, puts sunscreen to shame
Photovoltaics suffer from gross inefficiency, despite incremental improvements in their power producing capabilities. According to research by a team led by a University of Missouri professor, however, newly developed nantenna-equipped solar sheets can reap more than 90 percent of the sun's bounty -- which is more than double the efficiency of existing solar technologies. Apparently, some "special high-speed electrical circuitry" is the secret sauce behind the solar breakthrough. Of course, the flexible film is currently a flight of fancy and won't be generating juice for the public anytime soon. The professor and his pals still need capital for commercialization, but they believe a product will be ready within five years. Take your time, guys, it's not like global warming's getting worse.

Nanocones make solar cells more efficient, sinister looking
Going green is de rigeur, so the sun is becoming a much-preferred source of power. However, solar cells' inefficient harvesting of heliacal energies is a major reason they haven't usurped the power of petroleum. Good thing the big brains at Oak Ridge National Laboratory are looking to change that with nanocone-based solar technology. The teeny-tiny cones are made of zinc oxide and create "an intrinsic electric field distribution" to improve electrical charge transport within solar cells. We aren't sure what that means, but we do know the prickly-looking design provides a 3.2 percent light-to-power conversion efficiency that's a substantial improvement over the meager 1.8 percent offered by today's flat photovoltaics made of similar materials. That's 80 percent more efficient, and 100 percent more awesome.
