Data centres (DCs) and telecommunication base stations (TBSs) are energy intensive with ∼40% of the energy consumption for cooling. Here, we provide a comprehensive review on recent research on energy-saving technologies for cooling DCs and TBSs, covering free-cooling, liquid-cooling, two-phase cooling and thermal energy storage based cooling.
To maintain the indoor temperature of DCs or TBSs, the computer room air conditioning (CRAC) system and chilled-water system have been developed which are energy intensive (Borah et al., 2015) and contribute more carbon emissions.
Energy-saving cooling technologies, as environmentally friendly and low-cost cooling solution, have been developed low-carbon, energy-efficient and achieving sustainability (Cho et al., 2017). Such cooling technologies could be applied to DCs and TBSs since their servers and racks have similar layouts.
They also showed an increase of the annual coefficient of performance (COP) of the TBSs by 23.7% with the ESR reaching 19.2% with the full utilization of natural cooling sources (Dong et al., 2017).

What is a wind turbine? A wind turbine, or wind generator or wind turbine generator, is a device that converts the kinetic energy of wind (a natural and renewable source) into electricity. Whereas a ventilator or fan uses electricity to create wind, a wind turbine does the opposite: it harnesses the wind to make electricity.
Ans:A wind turbine generates electricity by using the wind to turn its blades. The blades are connected to a rotor, which spins a generator inside the turbine. This movement converts kinetic energy from the wind into mechanical energy, which is then transformed into electrical energy by the generator. the long run.
Wind power generation is power generation that converts wind energy into electric energy. The wind generating set absorbs wind energy with a specially designed blade and converts wind energy to mechanical energy, which further drives the generator rotating and realizes conversion of wind energy to electric energy.
There are many wind turbine generator types based on how they are designed and functions. However, in this guide, we will mainly look into the Horizontal-Axis and Vertical-Axis wind turbines. Horizontal-Axis Wind Turbines (HAWTs) are the most common type of wind turbine – the ones that all of us would have seen the most.

According to the mobile telephone network (MTN), which is a multinational mobile telecommunications company, report (Walker, 2020), the dense layer of small cell and more antennas requirements will cause energy costs to grow because of up to twice or more power consumption of a 5G base station than the power of a 4G base station.
There are several potential advantages of RE in 5G mobile networks. First, for the network operator, RE can reduce the cost of energy consumption by deploying solar or wind energy base stations. RE enabled BSs can use solar energy for operation in the daytime, along with storing it in rechargeable batteries.

Small Wind Energy and Hybrid Systems Programme Introduction - The combination of renewable energy sources, wind & solar are used for generating power called as wind solar hybrid system. This system is designed using the solar panels and small wind turbines generators for generating electricity.
Combining small wind turbines and solar panels is a popular solution because they complement each other. With hybrid renewable energy systems, we don't have to rely on a single energy source. While solar panels excel on sunny days, wind turbines can generate power day and night in windy seasons.
Solar panels generate the most energy during sunny days, particularly in summer. Meanwhile, wind turbines perform best during cloudy, windy, or nighttime conditions, often peaking in colder months. This means that when one energy source slows down, the other often picks up, ensuring a more consistent power supply throughout the day and year.
In the quest for green energy, the combination of small wind turbines and solar panels presents a harmonious partnership. Wind turbines generate power in windy conditions, complementing solar panels that thrive under sunlight. This dynamic duo ensures a more consistent energy output, reducing reliance on a single source. 2.

The complementarity between wind and solar resources is considered one of the factors that restrict the utilization of intermittent renewable power sources such as these, but the traditional complementarity ass.
The results reveal that wind energy and solar energy resources in China undergo large interannual fluctuations and show significant spatial heterogeneity. At the same time, according to the complementarity of wind and solar resources, over half of China's regions are suitable for the complementary development of resources.
To this end, we propose a novel variation-based complementarity metrics system based on the description of series' fluctuation characteristics from quantitative and contoured dimensions. From this, the complementarity between wind and solar resources in China is assessed, and the trend and persistence are tested.

Jurasz et al. simulated the operation of wind-solar HES for 86 locations in Poland.
Finally, we also strive to harmonize regions where wind and solar resources are less complementary by introducing hydro-energy resources. The results reveal that wind energy and solar energy resources in China undergo large interannual fluctuations and show significant spatial heterogeneity.
Generally, the wind and solar resources in China have a gratifying complementarity. Moreover, the regions rich in wind and solar resources usually show this strong complementarity, such as Qinghai, Gansu, Ningxia, Inner Mongolia, Xinjiang, western Jilin, and western Heilongjiang.
However, for the regions with relatively poor wind and solar resources, such as central Tibet, eastern Sichuan, western Yunnan, Chongqing, Guizhou, Zhejiang, Guangdong, and Guangxi, the complementarity is relatively weak.
