Building A Greener Grid - Forbes.com - 0 views

  •  
    The paper itself is flawed suggesting that virtualisation can reeduce the number of servers required to 7% - enough to handle the average processing load. Webusers want instant reaction during the peak - for that you need spare capacity. Is this a surprise?
  •  
    The Internet doesn't produce belching smokestacks or toxin-spewing drainpipes. Instead, the environmental impact of the data centers that power the Web and private networks is about as visible as the electrons moving around a company's servers. But visible or not, the ecological and economic costs of those servers are massive. A report released last week by the Environmental Protection Agency estimated that U.S. data centers (collections of computers used to power businesses' and government agencies' IT infrastructures and Web sites) consumed around 61 billion kilowatt-hoU.S.in 2006 at a cost of about $4.5 billion. That's about 1.5% of total U.S. electricity consumption, more than the electricity used by American televisions, or equivalent to the output of about 15 typical power plants

Unlocking Energy Efficiency in the US Economy: $ 700 Bn potential - 0 views

  •  
    The research shows that the U.S. economy has the potential to reduce annual non-transportation energy consumption by roughly 23 percent by 2020, eliminating more than $1.2 trillion in waste - well beyond the $520 billion upfront investment (not including program costs) that would be required. The reduction in energy use would also result in the abatement of 1.1 gigatons of greenhouse gas emissions annually - the equivalent of taking the entire U.S. fleet of passenger vehicles and light trucks off the roads.

Superconductors: Cure for grid transmission woes? | Green Tech - CNET News - 0 views

  •  
    "The big barrier here, as with any new technology, is that electric utilities are very conservative...Now we're overcoming that obstacle with initial installations, which are relatively short runs but this superconductor pipeline is much grander in scale," he said. In practice, the cables would be placed underground, as gas pipelines are, and have nitrogen cooling stations every seven or eight miles. Fredette said the technology is feasible but would likely need some sort of loan guarantee from U.S. government to test the system in the field.

Small wind turbine works at low wind speeds | Green Tech - CNET News - 0 views

  •  
    Homeowners this fall will be able to buy a wind turbine at hardware stores that tackles the small wind industry's bete noire: slow wind. WindTronics has developed a wind turbine sized for individual homes that it says can operate at speeds as low as 2 miles an hour. It will be sold for $4,500 as the Honeywell Wind Turbine... ... generate 2,000 kilowatt-hours in a year for a home with a very good--called Class 4--wind resource, according to the company. That's between 15 and 20 percent of the annual electricity consumption for the average U.S. home.

Utilities prepare to open natural gas pipes to biogas - 0 views

  •  
    I have a story today on Enbridge Gas Distribution and its early investigation of biogas-injection into its natural gas pipelines. It's already being done in several European countries and some U.S. states, and is even mandated in countries such as Germany. Enbridge, and Terasen Gas in British Columbia, are among a number of gas utilities in North America that are trying to prepare themselves for the day when "bio-methane" will become a common component of natural gas pipeline infrastructure. Will the biogas quality affect the pipeline? Can it be used in all natural gas appliances without problem? How much does it cost to scrub out impurities? What's the best source: landfills, sewage treatment plants, biodigesters? All qU.S.ions that are being asked and answered. Indeed, the Gas Technology Institute is in the middle of a $1.6 million (U.S.) study aimed as answering these qU.S.ions.

Sizing the smart appliance opportunity - 1 views

  • AHAM lists the following six key features associated with smart appliances: Dynamic electricity pricing information is delivered to the user It can respond to utility signals Integrity of its operation is maintained while automatically adjusting its operation to respond to emergency power situations and help prevent brown or blackouts The consumer can override all previously programmed selections or instructions from the Smart Grid, while ensuring the appliance‘s safety functions remain active When connected through a Home Area Network and/or controlled via a Home Energy Management system, smart appliances allow for a total home energy usage approach. This enables the consumer to develop their own energy usage profile and use the data according to how it best benefits them It incorporates features to target renewable energy by allowing for the shifting of power usage to an optimal time for renewable energy generation, i.e., when the wind is blowing or sun is shining According to a research piece written by Zpryme, the smart appliance market is projected to grow from $3.06 billion in 2011 to $15.12 billion in 2015, with the U.S. accounting for 46.6 percent of that in 2011 and 36 percent in 2015. By contrast, China is expected to have an 11.6 percent share in 2011 and an 18.2 percent share in 2015. What's more, there are some strong drivers to smart appliance investment: Pricing: Bringing smart appliances to the mainstream means aligning ecological innovation with affordability Environment: With the build-out of metering and real-time pricing, consumers will see economic and environmental incentives for reducing power consumption first hand with their smart appliances Energy efficiency: When a consumer bU.S.an appliance, they commit to paying both the first cost and the operating cost for the life of the product. And over the existence of the appliance, the energy cost to run it could be significantly greater than the initial cost Smart grid build-out: Smart appliance growth relies heavily on how quickly smart grid infrastructure can be rolled-out and readily accessible to communities Government sU.S.dies: Like the Cash for Appliances program in the U.S., governments could and should play an active role in furthering the smart appliance agenda

U.S. Renewable Energy Growth Accelerates (ENN) - 0 views

  •  
    Renewable energy markets surged in the United States in the first half of this year despite uncertainty over federal tax credits and a sluggish national economy, according to mid-year figures. Wind, solar, and geothermal energy are all on the rise. At least 17,000 megawatts (MW) of these three energy sources are now under construction. According to the Energy Information Administration, renewable energy will account for about one-third of new electricity generation added to the U.S. grid over the next three years.

Clean Break :: Battling the cold with new air-source heat pump - 0 views

  • natural gas is okay but it's not ideal. It still emits greenhouse gases and NOx. It's also becoming more volatile and is likely to become much more expensive over the coming years. Also, the power mix in Ontario will become cleaner over the next decade -- no coal, more nuclear, hydroelectric, wind and natural gas. So there's an argument that heating your home with electricity could be cleaner than using natural gas, if you can do it efficiently -- in other words, if you can find a better way than using resistance heating.
  • a 34-year-old engineer who was a cryogenics expert with the U.S. Navy, realized that conventional air-source heat pumps that are popular in the U.S. south do not perform well in cold climates and are therefore not economical. So he went ahead and built his own, called Acadia, and it can operate efficiently down to minus 30 degrees C.

    Interesting, but a bit thin on specifics, and still a long way to market.
