The most immediate way to reduce CO2 emissions in the telecommunications sector is by introducing renewable energy sources such as solar, wind and biofuels. These emissionfree or low-emission energies represent effective choices for telecommunications operators to reduce carbon emissions. The substantial decreases in the power consumption of telecommunications equipment have made it possible to adopt new energy sources as power supplies in our industry. Huawei's new energy solutions focus on the need for energy savings and emission reduction. It incorporates the green concept and the request for reduced OPEX into the design of site products, and it has the flexibility to customize equipment and networks to fit our customers' individual requirements and the local climatic factors where the network will operate.
Huawei's renewable energy solutions have been widely used in China and the Middle East. In 2008, Huawei was granted commercial contracts by a number of operators in Africa that included the deliver o f 200 solar-powered sites, making us one of the wireless solution providers with the most solar base station sites for the year.
Solar solution
As a mature technology, solar energy has little negative impact on the environment, low maintenance requirements and high reliability.
Wind/solar solution
Solar energy complemented by wind energy to accommodate di f ferent scenarios, such as daytime versus night and sunshine versus rain, protects the power supply and improves system reliability.
Solar/diesel solution
As olar / diesel solution , wh i c h complements the solar solution with a diesel generator as backup, is able to supply power regardless of cloudy or rainy days or volatile sunshine peaks in different months.
| Located on the northeast of the Qinghai-Tibetan Plateau, China's Qinghai province boasts abundant sunlight and rich resources. With such a favored climate, and Huawei's low-energy consumption access equipment, China Mobile Qinghai successfully deployed the "wind/solar" hybrid solution. The solution leverages renewable energy sources including solar energy and wind energy, saving a significant amount of electric power, and is almost maintenancefree within the service life of solar components and wind turbines. |
