Journal 14: 5th generation wireless systems（5G）

With the development of technology, 5G has begun to gradually replace 4G at this stage. Its performance target is high data rate, reduce latency, save energy, reduce cost, improve system capacity and large-scale device connectivity. Such data transmission speed, which is far higher than 4G, can help cities develop more sustainably.

5G is an energy-efficient "green" technology precisely because it is so much faster than 4G. It is estimated that 5G will support 5,425GB of data at 1,000 watts of power, while 4G will only support about 200GB. It can be seen from the data that although 5G base stations consume more power overall than 4G, they are about 25 times more efficient than 4G. Therefore, when 5G is fully integrated into cities, it will not only facilitate people's lives but also indirectly reduce the city's carbon emissions because it consumes less electricity.

In addition, 5G will be applied to all aspects of society and promote the informatization and digitalization of the entire industry, which will bring real efficiency improvement and energy consumption reduction in all industries. For example, smart transportation under the 5G network can effectively reduce vehicle congestion and travel time, and effectively reduce carbon dioxide emissions. At the same time, 5G can help improve production efficiency and reduce unnecessary waste at the production end, thus directly reducing the energy consumption needed for production.

Therefore, in my opinion, 5G will not bring environmental pollution and energy waste to society. On the contrary, it will help cities become more intelligent and reduce the energy consumption of urban development through its high transmission rate.

Journal 8: Madreselva Building / Vicca Verde

Image
  The Madreselva Building in Peru is a low-cost sustainable ecological Building designed by Vicca Verde in 2014. The building is located in the heart of the city, which is often lacking in greenery in modern cities, and this was one of the issues to be considered at the beginning of the project. The project takes into account the efficient use of materials and resources, and the local wood is specially treated to meet the requirements of being built as a tall building. In addition, it is environmentally friendly from the beginning of construction to the end of its life. This is helped by the use of recyclable materials that have a low environmental impact. Moreover, the rainwater collection system of the building can be used to irrigate the green plants around the building and realize the internal circulation system of the building. As a result, the design not only enhances the quality of life of the building, but also enables it to function well in low cost maintenance conditions. In

Journal 13 : Geothermal heat pump

Image
 The Geothermal heat pump system, and efficient renewable energy technology, has been widely accepted in residential and commercial buildings. Geothermal heat pumps are used for space heating and cooling and water heating. The advantage of ground source heat pumps is that they concentrate heat that occurs naturally, rather than generating heat by burning fossil fuels. Geothermal heat pumps can be used to provide domestic hot water when the system is running. Many residential systems are now equipped with thermostats, which transfer excess heat from the compressor of a geothermal heat pump to the house's hot water tank. When the local heat pump system is not working, the desuperheater does not provide hot water in spring and autumn. But because geothermal heat pumps are so much more efficient than other forms of hot water, manufacturers are starting to offer "full demand" systems, which use a single heat exchanger to meet all a home's hot water needs. These facilities

Journal 1: Kamuthi Solar Project

Image
        Image: Kamuthi Solar Project, source from: Greencitytimes India was the first country in the world to establish an official government agency for non-traditional energy, the Indian Ministry of New and Renewable Energy. India has been trying to find more sustainable sources of energy since the 1980s. The mission of the Ministry of New and Renewable Energy is to "increase the share of clean energy, increase its availability, improve its accessibility, increase energy affordability and maximize energy equity", with India aiming to provide solar power to more than 60 million Indian homes by 2022. The Kamuthi Solar Project is a solar photovoltaic (PV) farm capable of providing 648 megawatts of power. It is located in the town of Kamuthi, Ramanathapuram, India. It has more than 2.5 million individual Solar PV modules on 2,500 acres. The Kamuthi solar project provides energy to about 300,000 homes. Moreover, the project cost $710 million and became operational in 2016. Grow
