Explanatory Notes on Main Statistical Indicators

 

Total Energy Consumption   refers to the total consumption of energy of various kinds by material production sectors, non-material production sectors and households in the country (region) in a given period of time. It is a comprehensive indicator to show the scale, composition and development of energy consumption. The total energy consumption includes that of coal, crude oil and their products, natural gas and electricity. However, it excludes the consumption of fuel of low calorific value, bio-energy and solar energy. Total domestic energy consumption can be divided into three parts:

 (I) Final energy consumption: refers to the total energy consumption by material production sectors, non-material production sectors and households in the country (region) in a given period of time, but excludes the consumption in conversion of the primary energy into the secondary energy and the loss in the process of energy conversion.

 (II) Loss during the process of energy conversion: refers to the total input of various kinds of energy for conversion, minus the total output of various kinds of energy in the country in a given period of time. It is an indicator to show the loss that occurs during the process of energy conversion.

(III) Loss: refers to the total of the loss of energy during the course of energy transport, distribution and storage and the loss caused by any objective reason in a given period of time. The loss of various kinds of gas due to gas discharges and stocktaking is excluded.

Elasticity Ratio of Energy Consumption   is an indicator to show the relationship between the growth rate of energy consumption and the growth rate of the national economy. The formula is:

Elasticity Ratio of Energy Consumption=Average annual Growth Rate of Energy Consumption/ Average Annual Growth Rate of National Economy.
