Executive summary
In a nutshell
Ovum view
Key messages
Wide divergence of approaches with no clear industry standards and metrics
Service providers generally not willing to trade off higher capex now for lower power-related opex later
Macroeconomic meltdown has increased the market' s focus on reducing power consumption
Industry focus on power reduction will increase over time
Architectural change/network transformation is not being done explicitly to reduce power consumption
There are benefits to power reduction beyond mere cost-reduction
What' s the problem with network power? The impact of traffic growth on networks and network power
Power can' t increase linearly with network traffic growth without massive negative consequences
Within wireline networks, routers present the biggest challenge
Ovum survey results: Power usage as a relative concern
Service providers
Summarized service provider survey responses
Industry wide, power accounts for 2-3% of opex, and this is likely to rise
The BT case: An aggressive approach to power reduction, in context
Is power consumption rising, and what other concerns are similarly or more than power?
The macroeconomic meltdown has not decreased focus on power issues
Usage “hot spots” in the network and beyond
Power usage inside the customer premise
Business risks from not addressing power consumption
Steps taken thus far to reduce power
The looming problem of network scaling
Operators remain reluctant to trade off increased capex now for decreased opex tomorrow
Vendors
Summarized network equipment vendor survey responses
Importance of power relative to other things in product development, sales and marketing
Impact of macroeconomic meltdown on level of concern
Identifying power “hot spots” and developing reduction strategies at the network element (NE) level
Measuring power consumption
Identifying power “hot spots” and developing reduction strategies beyond the NE
Comparing products will require more agreement on metrics and how to calculate them
Optical networking products: Alcatel-Lucent as an example
Service provider router trends using Juniper products as an example
Optical and switch/router gear appear to be apples and oranges for now - very hard to compare directly
Enterprise routing trends - Cisco EnergyWise
Power-savvy element/network management systems
New architectures
IPoWDM
All optical networking
Ethernet switching vs. IP routing
Flow routing
Beyond the network: Other influences and considerations on the quest to reduce network power
Wide range of telecoms applications for using the network (connectivity) to lower emissions
Telecom' s ability to reduce greenhouse gas emissions
Regulatory issues
Corporate citizenship and branding issues
Power availability: A growing issue as wireless penetration has expanded

Using renewable energy - solar and wind - to power cell sites
Creation of additional revenue streams by selling extra electricity capacity generated by the solar panels
Main challenges of solar/wind-powered sites
Initiatives from solar panel manufacturers to sell directly to operators
Biofuel solutions for remote sites also being explored
Fuel cell technology holds some promise even though in early stages
