Climate change is increasing its impact. Countries around the world are setting ambitious targets to reduce greenhouse gas emissions. To achieve these goals, cities will need to use significantly less energy than today. In this article, we discuss how smart cities can benefit against climate change.
What is a smart city?
Smart city uses information and communication technologies to increase operational efficiency, share information with the public, provide better quality public services and improve citizens' well-being. The main goal of smart cities is to optimize city functions using smart technologies and data analysis, promoting economic growth while also improving the quality of life for citizens. Value depends on how those technologies are used rather than how much technology is available.
5G technology and smart cities
5G technology has a number of features that will positively impact digital experiences and smart cities. In addition to higher data upload and download speeds, 5G stands out with its very short latency and the ability to connect multiple devices at the same time.
Less latency means shorter time between sending and receiving the signal. 5G brings latency to under 10 milliseconds. This time is twice as short as what the most advanced 4G can achieve. In ideal scenarios where 5G is implemented, the delay time can be reduced to 1 millisecond, thus enabling real-time data transfer.
Another of the most beneficial features of 5G for smart city sensors and devices is that it supports greater device density. Even if there are tens of thousands of connected devices on the network, the speed and latency performance of the 5G network remain stable.
The combination of high density support and low latency has the potential to revolutionize smart cities. Nowadays, public wireless connections offered in crowded holiday spots or stadiums can become heavy due to density. In 5G, which will change this, it will be possible to support up to one million connections per square kilometer. In this way, in addition to personal devices such as smartphones, tablets, smart speakers and PCs, many other devices, objects and sensors will seamlessly capture information and communicate with each other.
What are smart city applications?
Smart cities use a variety of software, user interfaces, and communication networks, as well as internet of things (IoT) technology, to deliver solutions to citizens. The most important of these, IoT, is a network of connected devices that communicate and exchange data. An IoT network can include a wide variety of devices, from vehicles to home appliances and street sensors. Data collected from these devices is stored in the cloud or on servers to improve the efficiency of both the public and private sectors and provide benefits to the lives of citizens.
Most IoT devices operate on edge computing, which ensures that only requested and important data is transmitted over the communication network. Security systems are used to protect and monitor data transmission in the smart city network and prevent unauthorized access to the IoT network.
Combining automation, machine learning and IoT enables the diversification of smart city applications. Today, smart cities work with applications that provide energy saving and environmental efficiency, such as street lights that dim when the roads are empty. Such smart grid technologies provide improvements in many areas, from operation to maintenance, from planning to power consumption. Smart city initiatives are being used to address climate change and air pollution, as well as waste management and sanitation through connected waste collection and fleet management systems. Smart city technology, which can connect all kinds of services to provide integrated solutions to citizens, increases the efficiency of production, urban agriculture and energy use. Smart buildings, on the other hand, provide real-time management capabilities to determine when repairs are necessary.
What can smart cities change in climate change?
Today, 55% of the world's population lives in urban areas, and this rate is expected to increase to 68% by 2050. Cities are responsible for a large portion of the world's economic activity, energy consumption and greenhouse gas emissions. Therefore, to significantly reduce emissions, city centers need to both use less energy and make more use of renewable energy. Smart cities are expected to play a crucial role in achieving these goals.
Although we have not yet reached smart cities managed with end-to-end smart systems, some cities have started to apply smart technologies very effectively. For example, important initiatives are being undertaken in Singapore, which is often cited as the best global smart city. Beeline, which was first piloted in 2015, determines bus routes upon the request of city residents. In this way, more efficient public transportation reduces the use of private vehicles.
Smart cities can reduce electricity and heat production and help reduce greenhouse gas emissions produced by the transportation sector. The transportation sector accounts for 14% of global greenhouse gas emissions, while electricity and heat generation contribute 25%. With the deployment of 5G, not only will consumer experiences and business productivity improve, smart cities will also enable more effective responses to climate change and global warming. will enable you to give.
What are the harms of climate change?
The effects of climate change on different sectors of society are interrelated. Drought can harm food production and human health. Floods can damage ecosystems and smart infrastructure. Human health problems can increase mortality rates, affect food availability, and limit worker productivity. The effects of climate change are seen in every aspect of the world we live in. However, the effects of climate change are not equal across countries and the world; The effects of climate change may differ even among neighborhoods or individuals within a single community. Long-standing socioeconomic inequalities can make underserved groups, who are often most exposed to hazards and have the fewest resources for response, more vulnerable.
Can climate change be prevented?
Climate change can be prevented. Although it seems unlikely that we will be able to stop global warming overnight or even in the next few decades, we can slow the pace of global warming and limit its effects by reducing human-caused carbon emissions. If all greenhouse gas emissions caused by humanity were to stop today, Earth's temperature would continue to rise for several more decades as ocean currents would bring excess heat stored in the deep ocean back to the surface. When this excess heat radiated into space, the Earth's temperature would stabilize.
