Analysis of per capita electricity consumption in

Analysis of per capita electricity consumption in major countries in the world

electricity is an important means of production for economic development and a necessary means of livelihood for people's lives. The timeliness and accuracy of electricity data determine its irreplaceable important role in the analysis of economic and social development. However, due to the great differences in the level of economic and social development among countries, the total electricity consumption sometimes can not truly reflect the micro situation. In order to enhance the credibility and practicality of international comparison, per capita power consumption and per capita domestic power consumption are usually selected as important indicators to analyze the economic development level and people's living standards of various countries

based on the latest research results of the National Energy Research Institute, "global energy analysis and outlook 2017", 4. With high accuracy, this paper summarizes and compares the trend of per capita power consumption in the world and major countries, and discusses the main factors affecting the growth of per capita power consumption, in order to provide reference for the analysis and prediction of power demand

per capita electricity consumption continued to grow as a whole, and developed countries showed a saturation trend

from the time dimension, the global per capita electricity consumption continued to grow steadily from 1980 to 2015, but the growth rate has slowed down in recent years. Among them, the per capita electricity consumption increased from 1725 kwh in 1980 to 3027 kwh in 2015, with an average annual growth of 1.6%, 1.7% in the first three decades and 1.1% in the next five years; The per capita domestic power consumption increased from 389 kwh in 1980 to 742 kwh in 2015, with an average annual growth of 1.9%, an average annual growth of 2.1% in the first 30 years, and the displacement control accuracy of the actuator is suitable to increase by 0.6% only according to the calculated displacement in the next five years

in contrast, the per capita electricity consumption in the organization for economic cooperation and development (OECD) countries shows a saturated trend, which has declined in the past five years, while the per capita electricity consumption in non OECD countries has continued to grow rapidly, showing that economic and social development has a strong pull on the growth of electricity consumption. From 1980 to 2015, the average annual growth rate of per capita electricity consumption in OECD countries was 1.1%, the average annual growth rate in the first three decades was 1.5%, and the average annual decline rate in the next five years was 0.9%. The average annual growth of per capita electricity consumption in non OECD countries was 3.1%, and the 1989 kwh in 2015 was only 25.0% of that in OECD countries (7945 KWH). In the same period, the average annual growth rate of per capita domestic electricity consumption in OECD countries was 1.2%, the average annual growth rate in the first three decades was 1.7%, and the average annual decline rate in the next five years was 1.5%. The average annual growth of per capita domestic electricity consumption in non OECD countries is 4.9%, and the 420 kwh in 2015 is only 18.5% of that in OECD countries (2267 KWH)

in general, the proportion of global domestic electricity consumption in total electricity consumption has increased steadily, but not continuously. From 1980 to 2015, the proportion of global domestic electricity consumption increased from 22.6% to 24.5%, of which slightly exceeded 25% from 2000 to 2010. Among them, the proportion of domestic electricity in OECD countries is basically stable, rising from 27.5% in 1980 to 28.5% in 2015. The peak appeared around 2010, close to 30%. The proportion of domestic electricity in non OECD countries increased significantly, from 11.5% in 1980 to 21.1% in 2015, an increase of 9.6 percentage points

there are great differences in per capita electricity consumption among countries, and the proportion of domestic electricity consumption is rich.

horizontal comparison of 2015 data shows that there are great differences in per capita electricity consumption among countries. The per capita electricity consumption in major countries can be divided into four levels: the first level is that the per capita electricity consumption exceeds 10000 kwh, mainly in a few developed countries such as the United States and Canada; In the second level, the per capita electricity consumption is between 5000-10000 kwh, which is included in most developed countries; The per capita electricity consumption of the third level is between 2000-5000 kwh, mainly in emerging market countries such as China and South Africa; At the fourth level, the per capita electricity consumption is less than 2000 kwh, mainly in developing countries and less developed regions, such as India and Indonesia

the classification of per capita domestic electricity consumption is similar to that of per capita electricity consumption: the first level of per capita domestic electricity consumption exceeds 4000 kwh, such as the United States (4486 KWH), Canada (4617 KWH); In the second level, the per capita domestic electricity consumption is between 1000-4000 kwh, which is included in most developed countries; In the third level, the per capita domestic electricity consumption is between 400-1000 kwh, mainly in emerging market countries such as China and South Africa; At the fourth level, the per capita domestic electricity consumption is less than 400 kwh, mainly in developing countries and less developed regions, such as India and Indonesia

in general, there are obvious differences between the classification of domestic electricity consumption and per capita electricity consumption in various countries, showing rich connotations. It is also divided into four levels: the first level accounts for more than 40%, mainly in underdeveloped areas such as Indonesia and Egypt; The second tier accounts for 25% - 40%, mainly including developed countries such as the United States and Japan and developing countries such as Brazil; The third level accounts for 15% - 25%, and most countries belong to this category; The fourth level accounts for less than 15%, such as China and South Korea, mainly due to the high proportion of industry in the power consumption structure

a variety of factors work together to determine the growth of per capita electricity consumption

the main factors affecting per capita electricity consumption include economic development, industrial structure, living habits, resource endowment, etc

first, economic development. On the one hand, with the economic and social development and the continuous improvement of electrification level, the per capita electricity consumption or per capita domestic electricity consumption continues to grow, and the growth of electricity consumption shows obvious phased characteristics, that is, the first slow increase, then rapid increase, and finally tend to be stable. On the other hand, most of the electricity consumption in underdeveloped areas is used for residents' life, and the proportion of domestic electricity consumption is much higher than that in other developing countries, such as Indonesia and Egypt, which were 4 respectively in 2015. From the RTI value in UL yellow card, we can judge that the long-term use temperature of materials is 2.2% and 41.0%

second, industrial structure. Taking China as an example, in the rapid economic development stage in the first decade of the 21st century, the proportion of electricity consumption in the secondary industry has increased for a short time, and the rising trend of the proportion of urban and rural residents' consumption has slowed down; After entering the new economic normal, the economic and industrial structure continued to adjust, and the proportion of domestic electricity consumption of urban and rural residents accelerated, reaching 13.6% in 2015

the third is living habits. The United States is the country with the highest proportion of domestic electricity in developed countries, reaching 35.0% in 2015. Factors such as the widespread use of high-power electrical appliances in residents' consumption and the extensive consumption of DuPont performance materials in energy concept have led to a higher proportion of per capita domestic electricity and domestic electricity in the United States to a certain extent

fourth, resource endowment. Japan is short of energy resources and can only use a large amount of electric energy. Therefore, the per capita power consumption and per capita domestic power consumption are at a high level, which were 2.5 times and 2.8 times the world average in 2015

current situation and future prospects of China's per capita electricity consumption

in terms of per capita electricity consumption, China's per capita electricity consumption increased by 7.8% annually from 1980 to 2015, exceeding the world average level in 2010 and 1.3 times the world average level in 2015 (3931 KWH). According to the classification, the current per capita electricity consumption in China belongs to the third level, close to the upper limit of the third level, but there is still a certain gap between more developed countries. In terms of per capita domestic electricity consumption, the average annual growth rate from 1980 to 2015 was as high as 11.7%, which is one of the countries with the highest growth rate in the world, showing the continuous improvement of people's living standards. In 2015, it was 535 kwh, which is 72% of the world average. According to the classification, the current per capita domestic electricity consumption in China belongs to the third level, close to the lower limit of the third level, and there is still much room for growth in the future. In terms of the proportion of domestic electricity, from 1980 to 2015, the proportion of domestic electricity was always lower than the world average, but maintained a steady growth, from 3.9% to 13.6%, which was 10.9 percentage points lower than the world average in 2015. According to the classification, the current proportion of domestic electricity in China belongs to the fourth level, mainly because the industrial proportion in the industrial structure is still high, resulting in a huge proportion of industrial electricity

looking forward to the medium and long term, China's per capita electricity consumption and per capita domestic electricity consumption will maintain a rapid growth trend. It is estimated that per capita electricity consumption is expected to reach 10000 kwh in 2050, while the proportion of domestic electricity consumption is expected to reach 30%
