Green Telecom

Light Reading has published a long article discussing the issues around green telecom. It describes why this is an important issue and different ways to approach it. Another interesting approach to this is contained in The Climate Group's Smart 2o20 report that takes a quantitative approach to this subject.

This is an important subject that is being addressed by the entire ICT industry including service providers and manufacturers. It will be important to push this agenda future.

Cisco Introduces Green Switches

Cisco introduced the Cisco EnergyWise technology for its Catalyst switches that measures, reports and reduces the energy consumption of IP devices such as phones, laptops and access points. It also announced industry partnerships along with a middleware acquisition that will enable the management of power consumption for entire building systems such as lights, elevators, and air conditioning and heating.

EnergyWise will roll out in three phases:

• In the first phase (February 2009), Network Control, EnergyWise will be supported on Catalyst switches and manage the energy consumption of IP devices such as phones, video surveillance cameras and wireless access points.
• In the next phase (Summer 2009), IT Control, there will be expanded industry support of EnergyWise on devices such as personal computers (PCs), laptops and printers.
• In the final phase (Early 2010), Building Control, EnergyWise will be extended to the management of building system assets such as heating, ventilation and air conditioning (HVAC), elevators, lights, employee badge access systems, fire alarm systems and security systems.

This is an interesting approach that leverages installed switches and Cisco's industry position to address energy management in businesses. I will not be surprised if Microsoft comes up with a similar offering on its servers.

FTTH Green Postitive in U.S. in Six Years

The FTTH Council has published a report by PricewaterhouseCoopers that shows that the environmental impact of the deployment of a typical FTTH network in the United States will be positive within less than 6 years in average considering only benefits associated to telecommuting.

FTTH is much greener than DSL or VDSL in the U.S. Both of these technologies require powered remotes, which significantly raises their energy requirements. This is a much more significant problem for VDSL than DSL.
