Sunday Morning: Green ICT and Rural Connectivity
News Feed
Reaching the Next Billion–How Green ICT Technology and Innovative Business Models Make Good Business Sense for Rural Connectivity: Telecom interests in this area are largely driven by regulations involving massive cooling and power use needs. Policy makers and cost of running business are aligned. Example case study in Stockholm: data center heat serves 60% of total heat market, heat pumps from other sources (sewage and sea water), data center heat recycled to warm buildings. Use cases and energy profiles will depend on characteristics of each location. Petroleum has been too cheap, now at point where we need to rethink that. Data centers heading toward using 12% of global power. DC environment may reduce power use by 11%, high voltage AC may save 9% but each have challenges. Another case study in Senegal: Problem with rolling blackouts (some areas have 4 hours of power and 20 hours of blackouts), growing energy needs as country develops. Senegal’s new data center designed by western standards but running off diesel generator 12 hours a day. Off-grid solar data center, server redesigns (e.g., lower power chips, LED lighting, solid state drives) raised efficiency from 15-30% to 90+%, cut carbon energy requirements, offers a compelling business case and sustainable solution, also a working model for other areas of Africa. Business challenge to use technology effectively, efficiently, intelligently; improving economic yield.
