    1. Will clean power and microgrids be the future of data centers?

      Will clean power and microgrids be the future of data centers?

      Will an idea to build a data center park powered by onsite clean energy and paired with a microgrid in Colorado, represent the future of data centers? Created by developer Craig Harrison, the Niobrara Data Center Energy Park is a proposal for a company or even the government to build one or more data centers on a one-square mile plot of land in Colorado’s Weld County.

      Harrison says the site is unique in that a natural gas power plant could be built on it (a gas hub is a few miles away), and has a sunny climate that would enable an onsite solar panel farm. These local clean energy sources could be connected in a microgrid that could add uptime security for a data center, as well as reduce efficiency losses from transmission.

    2. DC Generators Reducing Data Center Power Consumption

      DC Generators Reducing Data Center Power Consumption

      Maybe alternating current (AC) generators have been used more because they are of simpler construction than direct current (DC) generators, but whatever the rationale may be DC is making a comeback. In data centers, at least.

      Servers, landline telephone systems, several electric motors, batteries, ships and airplanes all run on DC. Facebook (News - Alert) adopted DC architecture for its Prineville, Ore. data center, ABB bought a controlling interest in Validus DC systems, which specializes in DC data center equipment, and General Electric bought Lineage Power, producer of DC equipment.

      'Big Data' Creates Big Opportunities
      While nearly every device is getting smaller and more efficient, information is getting much bigger and unwieldy. Billions of bits of data are streaming in from everywhere: buildings, vehicles, manufacturers, warehouses, government agencies, credit card transactions, traffic signals, the electric grid, and just about anything else that is connected -- wired or wirelessly -- to something else. This "internet of things," as it's been dubbed, already consists of a trillion connected devices, and it's growing exponentially.

    4. Disruptive Technology from the Desktop to the Data Center

      Disruptive Technology from the Desktop to the Data Center
      According to Wikipedia, a disruptive technology or disruptive innovation is an innovation that helps create a new market and value network, and eventually goes on to disrupt an existing market and value network (over a few years or decades), displacing an earlier technology. The term is used in business and technology literature to describe innovations that improve a product or service in ways that the market does not expect, typically first by designing for a different set of consumers in the new market and later by lowering prices in the existing market. Virtualization and software design have been the main drivers in the development of disruptive innovations in hardware.

    6. Once again, Efficiency is not the same as renewable supply - by Peter Judge

      Once again, Efficiency is not the same as renewable supply - by Peter Judge
      Happy New Year to you all. If we had to have a new year’s resolution in the world of green energy and green data centers, I guess it would be to maintain some clarity over the difference between efficient energy use, and renewable energy supply. We all know that we must do something about climate change (at least, all of us except the most ignorant climate-change deniers). What that should be depends on whether you think that we can cut our energy use by changing our habits and being more efficient, or keep our lifestyles just the same and change the way we generate our electricity. Ideas like smart grids and low-energy data centers play towards the path of greater efficiency, while moves to use wind and solar power are heading towards changing our energy sources. Both are green - but if your argument jumps relies on both, or flips ...

      Can We Build Tomorrow's Breakthroughs?
      Manufacturing in the United States is in trouble. That's bad news not just for the country's economy but for the future of innovation. In a hangarlike building where General Electric once assembled steam turbines, a $100 million battery manufacturing facility is being constructed to make products using a chemistry never before commercialized on such a large scale. The sodium–metal halide batteries it will produce have been tested and optimized over the last few years by a team of materials scientists and engineers at GE's sprawling research center just a few miles away. Now some of the same researchers are responsible for reproducing those results in a production facility large enough to hold three and a half football fields.

    8. Could Solar Power Be More Than Window Dressing?

      Could Solar Power Be More Than Window Dressing?
      Solar power has been only capable of producing a small part of data centre energy needs, but this may change, says Peter Judge Solar power has always seemed a good long term bet for renewable energy. After all, pretty much every single Joule of energy we use on the planet comes from the sun originally The sun’s energy is caught by plants, which make fuels, either through the long process of fossilisation producing oil and gas, or by directly producing wood, or man-made ethanol to burn. Animals’ energy comes from plants, and the sun drives the water cycle which produces hydro-electric energy. Nuclear power uses energy stored from older suns where the heavier elements are made. Geothermal energy does include energy originating on earth – it is the heat of the earth’s core, but it is maintained at that temperature by radioactive decay inside the earth.

      Green Energy Economics in Action
      I know that politicians are required to have an odd view of th world: what else would provide the ego necessary to think that they and they alone have the answers to life's problems? But when politics meets the green (or even Green) understanding of economics we do end up with some really rather strange results: Households currently pay £89 a year on their bills for the green energy drive, but this will increase every year to reach £280 by 2020, according to the Government’s Department for Energy and Climate Change (DECC).

    10. IBM Creates Solar Array For Data Centres

      IBM Creates Solar Array For Data Centres
      IBM has said its new solar array is the first to be designed especially for powering IT systems IBM has created a solar array system designed with the data centre in mind, arguing organisations could use it to reduce the carbon footprint of their existing IT infrastructure or power sites in areas without a reliable electricity supply. The company claims the 6,000 square foot array in Bangalore, India can power 50 kilowatts of computer equipment for 330 days per year, running five hours per day. The rooftop array currently supplies nearly 20 percent of the power requirements of IBM’s India Software Lab – which consumes around 25 to 30 teraflops of compute power.

    11. 10 Things To Be Thankful For In Greentech This Year

      10 Things To Be Thankful For In Greentech This Year
      As you sit down to your sustainably raised turkey (or Tofurky) dinner this year, it’s a good time to think about the things that have gone well for greentech in 2011. Yes, there have been a lot of clouds for the industry this year, with the Solyndra debacle and the overall recession, but there have been quite a few milestones this year. Here’s what I’m thankful about: 1. Cheap solar panels. The prices of solar panels and cells have dropped dramatically this year. That’s been difficult for solar makers trying to stay in business, but for solar consumers, that’s great news. According to a recent study from Lawrence Berkeley National Labs, between 2009 to 2010 the price of residential rooftop solar panels fell 17 percent to $6.20 per watt, or a $1.30 decline, and in 2011 fell 70 cents per watt, or 11 ...

      Facebook, Yahoo!, QTS Data Centers Land LEED Ratings
      Efforts to make the data centers of major tech companies more energy efficient were recognized last week with LEED certifications awarded to a Facebook facility in Oregon, a Yahoo! site in Nebraska and a vast QTS data center in Atlanta -- the second largest in the world. Quality Technology Services, one of the larger providers of data center facilities and managed services, earned LEED-Gold certification from the U.S. Green Building Council for a 990,000-square-foot site in Georgia, the company said. The firm has worked to reduce and offset power at its Atlanta Metro Data Center in the four years since purchasing the property. Measures include installing a rainwater capture system as part of the site's cooling infrastructure and improving power usage effectiveness by 11.4 percent since January 2010. This past summer, the company hosted an EDF Climate Corps fellow who teamed up with the data center's ...

    14. Apple’s solar farm rumored to work with Leaf Solar

      Apple’s solar farm rumored to work with Leaf Solar
      Apple rumor site AppleInsider says the solar farm Apple is planning to build next to its billion-dollar data center will be built with the help of a company called Leaf Solar Power based in Lake Worth, Fla. While the article focuses on how the company is a U.S.-based company and not a Chinese solar company, Leaf Solar Power looks like it’s mainly a solar project developer, so could potentially (and very likely) use Chinese-made solar panels for the solar farm, if the farm is using solar PV. We just don’t have enough information about Apple’s solar project to know yet. Companies in the U.S. that want solar projects built on their campuses, or rooftops, or near factories, generally will work with a local solar project developer, which manages the construction of the farm, the financing and sourcing of the gear for the farm.

      Facebook to Install Hybrid Solar Power and Water System at New HQ
      Social media giant Facebook plans to install a rooftop solar power system that will provide hot water as well as electricity at the company's new corporate headquarters in Menlo Park, Calif. The hybrid 60-kilowatt system by the startup Cogenra will sit atop the building that houses the campus' 10,163-square-foot fitness center and is expected to generate enough energy to reduce natural gas needs by 60 percent and supply some of the electricity used in the gym. The energy from the system will be used to heat water for showers and power equipment and lights. Highly visible green energy systems are becoming a hallmark of leading businesses in Northern California's Bay Area, from REI's rooftop solar installations in Santa Rosa and San Francisco to Adobe's novel vertical wind turbines on its LEED-Platinum rated headquarters in San Jose.

    16. IBM brings solar power to data centers

      IBM brings solar power to data centers
      The company tomorrow will detail a pilot project that couples solar power with water-cooled servers that run on high-voltage direct current. The method results in about a 10 percent energy savings by reducing the losses that normally happen in converting from alternating power from the grid to the direct current servers run on, according to Kota Murali, the chief scientist of nanotechnology at IBM India who developed the pilot as a side project. That level of energy reduction is significant for large data centers with many servers, but the implications of solar and servers are potentially profound for places that don't have access to reliable power, Murali said. A bank, for example, that wanted to set up a remote branch and operate a data center could use solar power as a way to supplement power from the grid and on-site generators. IBM plans to offer the system in custom ...

    17. Facebook turns to solar for heat and power

      Facebook turns to solar for heat and power
      Facebook plans to build a solar system on the rooftop of its headquarters in Menlo Park, Calif., from startup Cogenra Solar, that will generate both electricity and heat. The system will be built on the company’s fitness center and in addition to electricity, will provide heat for the showers and will displace 60 percent of the building’s natural gas needs. Cogenra is a VC-backed Valley startup that has designed a hybrid solar system that uses both mirrors and solar cells to generate electricity and useful heat. The system uses a single-axis tracker, and relies on glass mirrors to concentrate sunlight onto silicon solar cells to produce electricity. In the same region where the cells reside is a fluid-containing tube that absorbs the heat produced from the process of electricity production.
