A Green Opportunity For Legacy Telecom Infrastructure

Vertatique emphasises 'Green ICT' over 'Green IT' to embrace the opportunities in communications infrastructures and operations: telecommunications, broadcast media, etc. One such opportunity in occurs as the global telecommunications networks migrate from a circuit switching (TDM) to packet switching. ('Data' communication now dominates traffic as even telephony moves to packets (VoIP).) An investor makes the case that his portfolio company making energy-saving migration switches is "cleantech". David Gold of Access Venture Partners writes in his GreenGold blog:

Aztek’s switches…reduce energy consumption by 90%…The roughly 16,000 TDM switches in the U.S. and Canada alone consume about 15,000 gigawatt-hours each year – roughly 0.4% of all electricity used in those two countries. Given that these switches run 24/7/365, they are a base load draw. That means that burning fossil fuels produces the vast majority of electricity utilized by them. The result is over 8 trillion tons of carbon emitted every year…

To put that in perspective replacing the aging TDM switches with Aztek’s technology is equivalent to installing over 42 million square meters of solar panels in Arizona where insolation is extraordinary (assumes insolation of 6.5 kwh/m2/day and 15% overall system efficiency). That would be almost 20 times the amount of electricity produced by all solar power in the U.S. in 2009.

…in California eliminating a pound of carbon emissions per year with solar costs roughly $3.50 or about $1.80 with all federal and state tax credits. Aztek eliminates a pound of carbon emissions each year for an equivalent cost of less than 50 cents per pound – without any tax credits. As much as 60% of the operating costs incurred by telecom companies for their TDM switches are from energy costs.
