In response to recent reports by relevant media about "China overtook the United States to become the world's largest energy consumer in 2009", China's National Energy Administration and the National Bureau of Statistics jointly issued a statement on the 11th, stating that in 2009, China's total energy consumption was less than 200 million more than the United States. Tonnes of standard oil, per capita consumption is about one-fifth of the United States.
According to a written statement made by the National Energy Administration and the National Bureau of Statistics, “according to the international method, China's energy consumption was converted into 2.146 billion tons of standard oil and 1.61 tons of standard oil per capita in 2009. According to the US Energy Information Administration’s website, published at the end of July. According to the data, US energy consumption totaled 2.382 billion tons of standard oil in 2009. According to official data released by China and the US, China’s total energy consumption was less than 200 million tons of standard oil in the United States in 2009, and per capita consumption was about one-fifth that of the United States. ."
Previously, the National Bureau of Statistics has released data on China's energy consumption in 2009. In order to objectively introduce the actual situation, the National Energy Administration and the National Bureau of Statistics issued a joint statement on the 11th to clarify relevant data on energy consumption in 2009.
The statement pointed out that in 2009, China's energy supply and demand experienced a gradual recovery from the low point after the international financial crisis to the recovery of the economy, and the steady growth after the national economy stabilized and recovered. “According to preliminary statistics, in 2009, the country’s primary energy production totaled 2.75 billion tons of standard coal, an increase of 5.2% over the previous year, an increase of 0.4%. The total energy consumption was 3.066 billion tons of standard coal, an increase of 5.2%, and an increase of 1.3. percentage point."
China's two departments stressed that China is in a period of rapid industrial and urbanization, and energy consumption is still growing. In recent years, in order to reduce the dependence of economic growth on energy, the Chinese government has vigorously promoted various energy conservation and emission reduction policies and measures, actively adjusted the industrial structure, and accelerated the elimination of backward production capacity. The overall energy consumption growth rate has generally slowed year by year, and energy consumption has continued to increase. Lowering, supporting a steady and relatively rapid development of the national economy with lower growth in energy consumption.
From 2004 to 2009, the growth rate of China's total energy consumption fell from 16.1% to 5.2%, a decrease of 10.9%, an average annual drop of 2.18 percentage points. During the first four years of the “Eleventh Five-Year Plan” (2006-2010), China’s energy consumption per 10,000 yuan of gross domestic product (GDP) fell from 1.276 tons of standard coal to 1.077 tons of standard coal, which fell by 2.74% and 5.04% respectively year-on-year. , 5.2% and 3.61%, a cumulative decrease of 15.61%, an average annual decline of 4.15%.
The total amount of energy consumption refers to the sum of all kinds of energy consumed by certain sectors of the national economy and households in a certain period of time. It includes all kinds of resources that can be obtained directly from nature or obtained through processing or conversion: raw coal, crude oil Primary energy such as natural gas, natural gas, hydropower, nuclear energy, wind energy, solar energy, geothermal energy, and biomass energy.
