      NREL data set shows clouds' effects on solar power
      The U.S. Department of Energy’s (DOE) National Renewable Energy Laboratory (NREL)has produced and made available a rich data set showing what happens, second-by-second, when clouds pass over a solar power installation. Seventeen measurement stations near Hawaii’s Honolulu International Airport on the island of Oahu collected data at 1-second intervals over the course of a year. The data set is of great interest to utilities, developers of large-scale photovoltaic (PV) systems, forecasters, system operators, laboratories and universities. By understanding the characteristics of cloud shadows that pass across a large PV system, utility officials can devise strategies to better manage those fluctuations so the grid isn’t adversely impacted. The sun reliably beams down on the Earth every day, and just as reliably clouds pass by each day, shading flora and fauna, buildings and mountains, for better or worse.

    6. The story behind Solyndra’s rise and fall

      The story behind Solyndra’s rise and fall
      If you hadn’t heard of solar startup Solyndra before, get ready to start hearing a lot more about the company. But not because of its great achievements. Solyndra just became a high-profile casualty of the youthful solar industry as Solyndra failed to compete successfully against larger solar rivals in a global market that depends heavily on government subsidies. The solar panel maker, known for its novel technology and for clinching a flagship $535 million federal loan guarantee in 2009 to build a factory, was supposed to become an American success story of greentech innovation and manufacturing. That loan guarantee, which came from the stimulus package, was meant to propel Solyndra from a startup to a full-fledged maker of solar panels and show how the U.S. will become a leader in clean power and green jobs.

    8. Coolerado Chills Snow & Ice Data Center

      Coolerado Chills Snow & Ice Data Center
      You’d think that The National Snow and Ice Data Center (NSIDC) would take data center cooling seriously. Indeed it does. The NSIDC is based in Boulder, Colorado, and supports research into the world’s “frozen realms,” including glaciers and polar climates. The organization recently undertook an overhaul of its data center cooling system that will reduce its energy spending by about 70 percent, according to David Gallaher, the manager of IT services. The NSIDC uses outside air in a free cooling system when the temperature is below 70 degrees. When it gets warmer than 70, the data center switches to an indirect evaporative cooling system from Coolerado. The group is also using a solar power array to provide supplemental power – including powering the Coolerado units in the event of a utility outage. In this three-minute video, Gallaher provides an overview of the system.

    12. The Trigeneration Data Center: What Is It?

      The Trigeneration Data Center: What Is It?
      Last week, the Data Center Journal (“Should I Be Generating My Own Power for My Data Center?”) discussed the possibility of data centers generating their own power—a strategy that involves greater capital costs but that can also yield tremendous benefits in terms of power quality and freedom from the vagaries of the power grid. For data centers that elect to generate some or all of their own power for operations, trigeneration offers a way to stretch fuel costs even further. Needless to say, implementing trigeneration infrastructure involves initial capital costs, but with energy prices continually rising, a properly planned and implemented trigeneration scheme can quickly provide a return on this investment. Trigeneration: What Is It? When a fuel such as natural gas or coal is burned, the result is heat energy and waste materials (gases such as carbon dioxide, for instance).

    18. Data Centres – Watch Japan’s Energy Crisis

      Data Centres – Watch Japan’s Energy Crisis
      Japan’s energy crisis is bringing about changes to data centres. The same thing will have to happen here, says Peter Judge When disaster struck Japan’s Fukushima nuclear power station in the 11 March earthquake, the first consideration was shutting down and ensuring safety. The long term effects could be more significant. Japan got nearly 30 percent of its power from nuclear plants, and now much of that is gone. In the wake of the disaster, other plants have closed, either as a direct result or for safety checks, and in May only 17 of the country’s 54 nuclear plants were in operation. That could imply that as much as 20 percent of the country’s electricity supply is in question – but actually, we don’t know what capacity the 17 reactors are working at, or how hard the 54 would have been working.

      Data Centers Look for Lower-Emission Cooling
      Putting computers near water is usually discouraged. But water could become vital for some companies seeking to cool the powerful servers that store and exchange vast amounts of information. Google, which runs five large data centers, is planning to open one of its most efficient facilities in a former paper mill on the coast of Finland later this year. “It’s the first time that I know that seawater has been used for data center cooling, but in other industries it’s actually quite common,” said Urs Hoelzle, a senior vice president at Google.

      Solar Flares/Storms affect on Data Center is not known, an answer with data collection
      One of the great talks at 7x24 Exchange was given by Alex Young on a subject few have thought about. NASA - The Influence of Solar Flares and Solar Storms: Why We Should Care About Space Weather The Sun produces solar storms in the form of intense radiation and fast moving material. These storms can interact with the Earth to create electric currents in our atmosphere. The study of space weather developed to predict solar storms and understand their impact on our technology. The world's electrical grids-that fundamental technology enabling modern society-are vulnerable to these currents. While most days the sun's impacts are minimal, large solar storms have the potential to have a devastating impact on mission critical systems. This talk will present an overview of Space Weather to help your business begin to prepare for worst-case scenarios. C. Alex Young, Ph.D., Solar Astrophysicist at NASA's Goddard ...
