Huawei is deeply concerned with climate change. We are committed to contributing to a low-carbon world by providing clean energy solutions, and enabling smart cities and industries which produce fewer carbon emissions. Through these efforts, we aim to make the world greener.
Smart Network Energy Solutions
In the ICT industry, a large portion of carbon emissions comes from generating the electricity used to power telecom networks(for transmitting information) and data centers (for storing information), though powering devices is also a significant factor. As more and more devices and equipment are connected, they will generate and transmit more information. This will require more network equipment and data centers, with a subsequent increase in the energy usage. To cope with these changes, Huawei has provided and deployed highly energy-efficient products and solutions to reduce carbon emissions.
Our highly energy-efficient network energy solutions and clean (solar) energy solutions have helped customers reduce energy consumption. We never cease innovating and we have proactively employed the latest technologies to help customers upgrade their existing energy systems.
Huawei’s Micro-modular Data Center Solution Helps China Unicom Guizhou Cut the PUE of Equipment in a Cloud Center to 1.3
As data usage climbs globally, data centers (DCs) are increasingly using more energy. We have constructed more than 660 DCs globally (including over 255 cloud DCs), and reduced their power usage effectiveness (PUE) to 1.45 thanks to our ongoing innovation and efforts over the past years. If natural cooling is used, this number can be further reduced to 1.2, ranking among the best in the industry.
Our micro-modular DC solutions are green, efficient, and particularly useful for on-demand DC deployment.
We have deployed micro modules for the China Unicom Guizhou cloud data center, with one micro module cluster integrating 48,000 servers. These modules are powered by uninterruptible power supply systems and use in-row air-conditioning technology to ensure precision cooling. We have also adopted leading technologies to drive energy efficiency improvements in areas such as buildings, electric systems, power supply systems, and equipment rooms. As a result, PUE can be further reduced to 1.3, far below that of traditional equipment rooms which stays between 1.5-1.8.
Huawei Helps Telstra Build a Highly Reliable and Efficient Power System
As Australia’s largest telecom company and a global Top 20 carrier, Telstra has 16 million mobile subscribers and 11.2
million fixed line subscribers, providing a full portfolio of communications products and services.
While providing high-quality communications services, Telstra also works to save energy and reduce emissions. Before cooperating with Huawei, Telstra planned to cut carbon emissions by 62% from 2015 to 2017 compared with its 2013 benchmarks. Its power system was old and unreliable, and it was hard to acquire spare parts. Energy efficiency was only 89.27% and power consumption was high across the network. As a result, Telstra’s power system was in urgent need of upgrading.
As a leading communications energy solutions provider, Huawei is committed to providing our customers with efficient energy solutions. To meet Telstra’s immediate need for energy conservation, emissions reduction, and reliability, we upgraded their power system by deploying rectifier modules with the world’s highest efficiency (98%). After the upgrade, the power system’s efficiency jumped to 97.96% (8.7% higher), saving 13,800 kWh of electricity per site per year, and cutting CO2 emission by 13.75 tons per site per year.
We also reused Telstra’s existing cabinets. With our ultra-dense energy solution, we saved 20U of space in existing cabinets that can later be used to house communications equipment and remove space constraints on capacity expansion.
More telecom sites will appear as network coverage and capacity worldwide continue to expand. This will inevitably
incur higher carbon emissions. To zalleviate this problem,Huawei provides our customers with energy-efficient network
energy solutions which consume less energy at telecom sites.On top of that, we are adopting clean energy solutions, such as solar-powered base stations, to minimize carbon emissions.
With our advanced energy scheduling technologies, we can intelligently schedule the use of solar energy, power grids,stored energy, and diesel for base stations. In addition to ensuring a sufficient power supply for sites, we have refined our power supply structure to prioritize the use of clean energy and circular energy storage systems. In areas without stable electric grids, we have deployed our solar hybrid energy solution, which significantly lowers energy use and
O&M costs for telecom sites.
Our pioneering smart photovoltaic (PV) plant solution is based on our two decades of experience in diverse spheres, including digital information, Internet, and PV technologies. Inspired by new concepts such as all digital,simplicity, and global and automated O&M, we aim to construct smart PV power plants that feature efficient electricity generation, smart O&M, and safe and reliable operations. PV power plants such as these will allow customers to enhance their return on investment and use clean energy on a larger scale worldwide.
Contributing to a Low-carbon Society with Huawei’s Smart PV Power Plant Solution
Huawei’s latest smart PV solution provides an open platform which is viable under diverse use scenarios such as fishery,subsidence areas, mountainous areas, and agriculture. The solution helps boost electricity generation and results in a 50% increase in O&M efficiency. It can also cut carbon emissions and deliver socioeconomic benefits.
Customers can apply the smart PV solution in their farms,without taking up the arable land. The land can thus generate revenue both from the electricity and from agricultural use.Our solution is both energy-efficient and ecologically friendly.
