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...

Apple to build a 20-megawatt solar farm for its Reno, Nevada data center

DNP Apple Nevada solar array

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

3D, lighttrapping 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.

DNP Inhabitat's Week in Green TKTKTK

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

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 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

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.
