Hou Jinlong, President of Energy & Infrastructure Product Line: Operators all need to implement cost-efficient energy solutions that utilize renewable sources, while continuing to improve the efficiency of legacy infrastructure.
Experts' Forum
Roel Louwhoff, CEO of BT Operate, which is responsible for managing BT's energy strategy, talks about how the telecom titan is going from green to greener.
Peng Peng, Huawei senior expert on onsite energy conservation: Microgrids, a cutting-edge technology, feature intelligent control systems that enable self-coordinated operation.
Lu Shaokun: Large and ultra-large data centers are becoming vital to the ICT industry, despite their higher energy & maintenance costs. Service providers face daunting challenges with saving energy and enhancing resource efficiency.
Main Topic
Adoption of cutting-edge power electronics technology, improvement of equipment energy efficiency, and large-scale application of solar power are three key measures to delivering a greener future.
Base stations are the key energy consumers on any mobile network; their monitoring & upgrade are essential if operators are to compete. With efficient monitoring & optimization, power consumption efficiency can be enhanced.
Besides improving network infrastructure, operators need to conserve energy, reduce operating costs, and minimize their carbon footprint; eco-friendly G3 (third-generation) sites provide an optimal solution.
How to Operate
By employing efficient power supply and simplifying its site network management system, Telefónica is closer to its target of 30% energy reduction by 2015.
To adapt to challenges brought by 3G deployment & power consumption reduction, China Mobile is modernizing its power system at the equipment & daily operational levels.
China Unicom Shandong has blazed a trail in energy saving & emission reduction with its energy-saving software, thermoregulated battery cabinets, and alternative energy sources.
Learn more about the onsite energy alternatives available to African operators.
Communication sites account for 45-70% of telcos’ total energy consumption and are thus the primary foci for their green programs, which aim for energy efficiency and independence.
Uninterrupted power supply for remote base stations is now possible through the combining of alternative power supplies with traditional sources.
The cloud computing boom will require a large number of data center equipment rooms that feature optimal application fulfillment, deployment suitability, and TCO. Modular, distributed, and intelligent design will help.
Cutting Edge
Fuel cells use hydrogen, together with oxygen from the air, to produce electricity and heat. They can be a viable solution for onsite backup power, thanks to their reliability, cost-effectiveness and eco-friendliness.
With the rapid development of the photovoltaic industry, the cost of solar energy has goes down dramatically; it will become a key energy player for sustainable growth over the next century.
