World Key Energy Data Statistics Report 2018

The Global Market Monitor recently released the "World Key Energy Data Statistics 2018" report, which compares the changes in the world's primary energy supply from the early 1970s to the last two years. It can be seen from the statistics that in the traditional energy sector, the total supply of coal and natural gas actually has a slight upward trend, while the overall supply of petroleum has declined significantly. 

Summary of the World Key Energy Data Statistics 2018:

Coal supply accounted for 23.1% in 1973, and the proportion increased to 28.8% by 2016. The proportion of natural gas increased from 17.1% to 23.2% while the share of oil supply fell from 46.3% in 1973 to 32.8% in 2017. The share of hydropower increased from 1.7% to 2.6%. This slight growth rate may be due to the limited resources for hydro development in recent years, and the area for hydro exploitation has almost been fully developed. It is worth noting that the biomass energy supply has reduced from 10.6% to 9.1%, which may be related to the policy adjustment of countries on biomass utilization although the decline is not obvious.

According to the analysis of the total energy supply from OECD, the general trend is not completely consistent with the world energy supply. The proportion of oil fell from 55% in 1973 to 36.5% in 2017, and natural gas increased from 18.8% to 27.2%. Coal fell sharply from 22.2% to 16.6%. Hydro is slightly increased by only 0.15%. Biomass energy increased significantly from 2.2% to 7%.

Judging from the proportion of energy supply in major regions in the world, Asia, Europe and the United States have developed rapidly, and Asia has occupied a half of the total proportion. In 1990, Asia just accounted for 29.2% of the world's energy supply, while Asia has reached 48.2% in 2017. Europe and the Americas have fallen by 15.5% and 5.8% respectively.
