    1. Enphase's Rooftop Solar Revolution

      Enphase's Rooftop Solar Revolution
      Martin Fornage found the idea for his company on a roof in 2005. A successful Silicon Valley telecom engineer who worked at Cerent (which was bought by Cisco), he had solar panels put on his home and needed an electrician to install a central inverter to convert the direct current (DC) power produced by the system into the alternating current (AC) power used in homes and businesses. Why didn't each solar panel have its own inverter? That would make installing the panels easier (no electrician needed) and safer (no high-voltage issues). So Fornage, 47, and Raghu Belur, 43, an electrical engineer Fornage had worked with at Cisco, founded Enphase Energy in March 2006, 40 miles north of San Francisco in Petaluma, Calif., home to several telecom companies. They spent a year designing a new kind of inverter called a microinverter, harnessing expertise in semiconductors, software, communications and power systems ...

      Inside Cisco’s New Texas Data Center
      In mid-2009, local media in Dallas reported that Cisco Systems (CSCO) had selected a site north of Dallas for a $180 million data center project. The company hasn’t had much to say about the new facility – until now. Yesterday Cisco launched Data Center 2011 Texas, an interactive tour of the new data center, which features the latest refinements to Cisco’s design. The new DC2 data center is about 15 miles north of the Cisco DC1 data center in Richardson, Texas.

      Computer Aid Solar Cyber Café Goes Live In Kenya
      Some of the poorest nations will soon have the ability to get online, even without electricity, thanks to solar powered Internet cafés from Computer Aid International. The idea for a portable cyber café in a standard 20 foot shipping container, which has built-in solar panels on the roof, was first revealed by the charity back in March this year. The thinking behind the concept is that it can be shipped to Africa and installed at any remote location, offering a connection to the Internet via cellular data connection, Wi-Fi or VSAT.

    5. Google's renewable energy investment pays off, finds 18,890 MW of Geothermal Power

      Google's renewable energy investment pays off, finds 18,890 MW of Geothermal Power
      Geothermal, unlike other renewable energy resources, can be easily used for 24/7 baseload power — that is, it doesn’t sag and surge with the sun and the wind, which is a problem with solar panels and wind turbines. Geothermal projects are on the rise, although venture capital and private equity investors haven’t yet shown much interest in the capital-intensive sector. Companies tackling geothermal power range from the startup Vancouver-based Magma Energy, which went public last year, to geothermal giants like Ormat Technologies. Google also has an internal solar technology project, as well as an energy-trading subsidiary, Google Energy, which bought 114 MW of wind energy via a wind farm in Iowa owned by NextEra Energy Resources. Google is likely shopping for more clean power to provide its data centers’ vast energy needs and help it with its pledge to go carbon-neutral — could geothermal help with that?

      State Department likes green IT, but not yet sure how much
      The State Department has launched several green technology initiatives, but officials have yet to develop ways to measure how much energy the projects save, the department's chief information officer said on Tuesday. What is known is that powering information technology equipment can cost a lot. At its Harry S. Truman Building headquarters in Washington, IT accounts for nearly 50 percent of the electric bill. The power is enough to operate more than 3,500 U.S. households annually, State's Chief Information Officer Susan Swart said.

      South Korea firms jump onto solar bandwagon
      outh Korea's technology giants are behind the pace in getting on the $35 billion global solar energy bandwagon, but are now making up for lost time, snapping up assets overseas. The push factors are compelling. The markets for their traditional businesses in chips and LCD screens are saturated and their margins thinning while their rivals in Japan and Taiwan are already racing ahead in the green technology arena. This year, the market share of South Korean companies in the global solar cells business is expected nearly double to 4.7 percent versus a year ago, according to Mark Jee, a senior researcher at Solar & Energy, a photovoltaic market research institute in Seoul.

    9. Iron, Power, and Cloud Computing: Let's Get Real

      Iron, Power, and Cloud Computing: Let's Get Real
      I'm the least sure of opinions that people are most sure of. And I'm supposed to be writing about Cloud Computing, not geopolitical debate. Whether we like it or not, these two things are intertwined, because the fundamental underlying all things Cloud is energy: its use, its price, and the competition for it. Most people have very strong opinions about energy--how we produce it and use it--and in my opinion, those opinions often cloud the debate. If you hate coal or nuclear power, you really hate them. If you are contemptuous of wind and solar, you are really contemptuous of them. But let's pretend we are the hypothetical Martians of old, and gaze down on Planet Earth to examine its needs dispassionately.

    12. China Beats U.S. on Renewable-Energy Investor Ranking

      China Beats U.S. on Renewable-Energy Investor Ranking
      China overtook the U.S. to lead a quarterly index of the most attractive countries for renewable energy projects for the first time, according to a list compiled by the global accounting firm Ernst & Young. After sharing the lead with the U.S. in the first quarter, China moved ahead of the world’s largest economy to rank as the most appealing nation for investing in wind and solar power projects, according to the report released today. The move follows the failure of U.S. Congress to pass legislation that would have required utilities to use clean energy. The Asian nation, the world’s biggest energy consumer, has set itself a goal of generating 15 percent of its electricity from renewable sources by 2020. It almost doubled consumer subsidies for renewable-power generation in the second half of last year to $545 million, the most recent period reported.

      On the GreenBeat: Solar Forecast Sours, 2 Million Smart Meters Installed Nationwide
      One hot topic right now is the future of the solar market, which is considered over-saturated. One writer, citing a conversation with a venture capitalist, calls this the “sunset of solar venture capital.” Noting analysts’ bearishness on solar going into 2011, the Motley Fool’s Travis Hoium bets on First Solar, but says Trina Solar and Yingli Solar also have a shot at making inroads into the residential and commercial market where SunPower reigns supreme. Jigar Shah at Cleantech Blog picks at Fool’s metric of cost per watt, saying widening efficiency gaps have rendered those numbers moot. “In any case, solar is coming down in cost and the race is fun to watch.” U.S. Energy Secretary Steven Chu announced yesterday that two million smart grid meters have been installed in the country as a result of funding from the Recovery Act. The release cites a study by the ...

      Ten Unique Data Center Designs
      Across the globe, many data center designs use an amazing amount of creativity in locating and deploying unique data centers. These are not your run-of-the-mill server rooms, but truly one-of-a-kind facilities that have a personality all their own. There is more to data center design than the straightforward mechanical approach, according to Rob Snevely, author of Enterprise Data Center Design and Methodology. “The detailed process of data center design appears on the outset to be a purely mechanical process involving the layout of the area, computations to determine equipment capacities, and innumerable other engineering details,” Snevely writes. “They are, of course, essential to the design and creation of a data center, however, the mechanics alone do not a data center make. The use of pure mechanics rarely creates anything that is useful, except perhaps by chance.” He goes on to discuss design philosophies that go back to classical times.
