The authors used the Google Trends tool to analyze the data from 2004 to the present, using “clean energy” as a search term, and the corresponding results can be seen in Figure 1. The results are shown in Figure 1, i.e., the overall search trend for this field is increasing globally, which directly indicates that the attention to clean energy is increasing worldwide.

From the analysis of the results of the country to examine, the top ten countries concerned about the heat are: Australia, Nepal, Singapore, the United States, Canada, the United Arab Emirates, Kenya, Germany, the Philippines, Austria. On the one hand, this shows the importance of the developed countries for the development of the industry; on the other hand, it also shows that the energy support for the less developed countries is also tilted from the application of clean energy.

Using the Chinese term “清洁能源” as the search term, the time span is 20110101-20230521, as seen from the results of Figure 2, the data shows the level of attention and continuous change of the Internet users to the keyword search. It is based on the search volume of Internet users in Baidu, and the weighting of the search frequency of each keyword in Baidu web search is scientifically analyzed and calculated with the keyword as the statistical object. According to the different data sources, the search index is divided into personal computer search index and mobile terminal search index.

As can be seen from the above graph, the number of related searches is generally on the rise, which directly illustrates the importance that China, as the world’s largest developing country, attaches to the clean energy industry and shows the corresponding national commitment.

Using the Chinese term “清洁能源” as the search term, the time span is 20130111-20230521, and the results in Figure 3 show that the level of attention to this issue on the Chinese web is steadily increasing, and such results are corroborated with the results analyzed by the Baidu index, which directly indicates that Chinese people are highly concerned about clean energy.

And considering the followers from the age dimension, there is Figure 4 which shows that the young and middle-aged group is highly concerned about this, which also shows that the clean energy industry will have the trend of developing vigorously in China. According to the results of the geographical analysis, the top ten provinces are: Guangdong, Jiangsu, Hebei, Fujian, Hubei, Shaanxi, Anhui, Zhejiang, Guangxi, and Qinghai. All of these regions are energy-consuming regions, so clean energy is highly valued in the industrial transformation and upgrading.

In terms of government administrative planning, the most direct feedback on whether the policy designation is effective comes from the effectiveness. Well, from the current effectiveness, thanks to our effective and scientific policy, the promotion and popularization of new energy industry is successful, and the development of this work has received a lot of attention.

Examining from an international perspective, although China has achieved a great deal of support and attention in the field of clean energy industry, there are still aspects that need to be improved compared to other countries in the world. Internationally, there are relatively few reports involving the development of China’s clean energy industry, and if China needs to occupy a dominant technological position in this field, then it should continue to promote the depth of scientific research and master the corresponding core technologies.

From the results of the previous analysis, it can be seen that the regions with high attention to clean energy are often the major energy-consuming provinces. The relatively low level of concern in other provinces also shows from one side that the development of this industry is utilitarian in all regions. However, the green upgrading of the industry is an inevitable trend, and the use of clean energy as an important part of it, deserves a high degree of attention around the world. Therefore, the publicity of this clean energy industry should be continued and carried out in depth.
