In the view of Wang Jian, an academician of the Chinese Academy of Engineering and an expert in cloud computing technology, urban digitalization can improve the efficiency of urban resources. On September 7, at the first China Digital Carbon Neutrality Summit Forum, he admitted that people's living standards are still improving even after reaching carbon neutrality, which is a very important manifestation of urban digitalization.
Wang Jian came up with a set of more general data. At present, 50% of the world's human beings live in cities, And China's urbanization rate has reached 60%, and the current trend of increasing data is still the same, and by 2050, more than 70% of the world's people live in cities. Therefore, cities are not negligible carriers, but at the same time, cities accommodate 50 to 60 percent of the population, but also consume more than 70 percent of the world's energy.
With this as the background, in Wang Jian's view, the city should be viewed as a subject. "Electrification is accelerating the use of resources by cities, with the top 100 cities accounting for about 20 percent of global carbon emissions." At the same time, from the current world electricity consumption data, the data of 2015 shows that the electricity consumed by industry and commerce in various major cities in the world is actually unbalanced with the electricity consumed by local people. For example, in the case of Los Angeles and New York, including Guangzhou and Shanghai in China, the electricity consumption and consumption of residents are unequal with their consumption in industry. This structural change is precisely where digital technology can play a very important role.
Another data shows that in 2020, China's electricity consumption is far more than the United States, but china's industrial and commercial electricity consumption is much higher than the United States, but our resident electricity consumption is lower than the United States, if the total amount is divided by per capita, in fact, our per capita residential electricity consumption is far lower than that of the United States. Wang Jian believes that digitalization plays a key role in this, that is, China uses the same amount of electricity consumption, but we can achieve a better quality of life.
In this regard, at the forum, Wang Jian used three very micro data to show the potential of urban digitalization in improving urban efficiency.
"You can imagine that when we talk about Chengdu this morning, we say that the number of motor vehicles in Chengdu is second only to Beijing, which shows that when talking about urban transportation, everyone looks at the number of motor vehicles." But at the same time, at the peak of a city, in fact, the cars on the road account for only about 10% of the ownership of motor vehicles, "here you can see a relationship between 90% and a 10%, to solve the resources required for 3 million vehicles, and to solve the resources of about 300,000 vehicles, for the city is a completely different resource." ”
For example, Wang Jian said, this is similar to a hotel that wastes a lot of energy because of unreasonable configuration, and those things can actually be completed without reducing consumption, "This is the role that digitalization brings to us." ”
Finally, he talked about the Internet, data, and computing. In Wang Jian's view, these are the three cornerstones of digitalization. Over the past 10 to 18 years, global computing has increased by more than 500%, while energy requirements have increased by only 6% at this time. From a technical point of view, we have the opportunity to use calculations to exchange for the reduction of our energy, so I personally feel that in the future, every additional kilowatt-hour of electricity should reduce the consumption of about 10 degrees of electricity for the world. "I personally think that cloud computing will have a very big impact on society like electricity in the era of electrification."
