  • HOMEPLUG®, ZIGBEE® ALLIANCES PREVIEW FUTURE DIRECTION OF SMART ENERGY HAN STANDARD - HomePlug Powerline Alliance on 2009-06-25
    • Chartwell's recent "Smart Metering Technology" report found that "40 percent of electric utilities prefer ZigBee compared to other in-premise standards."
    • 40 million homes and businesses
  • BiomassEnergy on 2009-06-22

    • Forest biomass energy systems are capable of using otherwise wasted or “unmerchantable” biomass.  Specific types of biomass targeted for use in energy systems include: tops and branches of trees left after timber harvests,  poor quality trees in managed forests, trees removed during land clearing operations,  wood waste from urban areas, and wood residues produced by sawmills.  As demand for these types of forest biomass increases, their value value will increase and they will become merchantable.

      Capital investment in the biomass plants will range from $400-500 million per facility, with each providing approximately 40 good-paying, full-time jobs.  In addition, each plant will require an annual investment of more than $30 million for fuel stock alone and will create a need for potentially hundreds of new jobs in the state’s forestry industry.

    • With 12 million people expected to call Georgia home by the year 2030, we will need more energy to meet the demand of our growing population,” said Chris Clark, executive director of the Georgia Environmental Facilities Authority (GEFA).  “The addition of Oglethorpe Power’s biomass electricity plants will help supply Georgians with homegrown energy that is clean and renewable.”
  • Energy Savers: Benefits of Geothermal Heat Pump Systems on 2009-06-19
    • According to the EPA, geothermal heat pumps can reduce energy consumption—and corresponding emissions—up to 44% compared to air-source heat pumps and up to 72% compared to electric resistance heating with standard air-conditioning equipment.
    • heat pumps often last 20 years or more

  • Mesh networking - Wikipedia, the free encyclopedia on 2009-06-12
    • Mesh networking is a way to route data, voice and instructions between nodes. It allows for continuous connections and reconfiguration around broken or blocked paths by “hopping” from node to node until the destination is reached
    • Mesh networks are self-healing: the network can still operate even when a node breaks down or a connection goes bad. As a result, this network is very reliable.
  • ZigBee - Wikipedia, the free encyclopedia on 2009-06-12
    • ZigBee is a low-cost, low-power, wireless mesh networking standard. The low cost allows the technology to be widely deployed in wireless control and monitoring applications, the low power-usage allows longer life with smaller batteries, and the mesh networking provides high reliability and larger range.
    • Because Zigbee can activate (go from sleep to active mode) in 15 msec or less, the latency can be very low and devices can be very responsive -- particularly compared to Bluetooth wake-up delays which are typically around three seconds. [5] Because Zigbees can sleep most of the time, average power consumption can be very low, resulting in long battery life.

  • Virtual power plants could tame coming grid chaos - tech - 11 June 2009 - New Scientist on 2009-06-11
    • The best solution suggested so far is a concept known as the "virtual power plant", says Lang. Each virtual plant consists of several hundred or thousand microgenerators lumped together in cyberspace into a unit comparable to that of a large power station
    • Implementing virtual power plants is possible with relatively little modification to existing infrastructure, says Lang
