Explanatory Notes on Main Statistical Indicators
Total Energy Production refers to the total production of primary energy
by all energy producing enterprises in the country in a given period of time.
It is a comprehensive indicator to show the capacity, scale, composition and
development of energy production of the country. The production of primary
energy includes that of coal, crude oil, natural gas, hydro-power and
electricity generated by nuclear energy and other means such as wind power and
geothermal power. However, it excludes the production of fuels of low calorific
value, bio-energy, solar energy and the secondary energy converted from the
primary energy.
Total Domestic 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 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:
final energy consumption, loss during the process of energy conversion, and
energy loss.
(1)Final Energy
Consumption: It 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.
(2)Loss During
the Process of Energy Conversion: It 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.
(3)Energy Loss: It 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 Production is an indicator to show the relationship
between the growth rate of energy production and the growth rate of the
national economy. The formula is:
Elasticity Ratio of Energy
Production = Average Annual Growth Rate of Energy Production / Average Annual
Growth Rate of National Economy
The average annual growth
rate of the national economy can be shown by the gross national product, gross
domestic product and other indicators, depending upon the purposes or needs.
The gross domestic product is used in calculation of the ratio in this chapter.
Elasticity Ratio of
Electricity Production is
an indicator to show the relationship between the growth rate of electricity
production and the growth rate of the national economy. Generally speaking, the
growth rate of electricity production should be higher than that of the
national economy.
Its formula is:
Elasticity Ratio of
Electricity Production = Average Annual Growth Rate of Electricity Production /
Average Annual Growth Rate of National Economy
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
Elasticity Ratio of
Electricity Consumption is an indicator to show the relationship
between the growth rate of electricity consumption and the growth rate of the
national economy. The formula is:
Elasticity Ratio of
Electricity Consumption = Average Annual Growth Rate of Electricity / Average
Annual Growth Rate of National Economy
Efficiency of Energy
Processing and Conversion refers to the ratio of the total output of energy products
of various kinds after processing and conversion and the total input of energy
of various kinds for processing and conversion in the same reference period. It
is an important indicator to show the current conditions of energy processing
and conversion equipment, production technique and management. The formula is:
Efficiency of Energy
Processing & Conversion = (Output of Energy After Processing &
Conversion / Input of Energy for Processing & Conversion)×100%
Energy Consumption per
Unit of GDP refers to the energy consumption per unit of gross domestic production in a country
or the gross region production in a region in the same reference period. The
formula is:
Energy Consumption per
Unit of GDP = Total Energy Consumption / Gross Domestic Production
Electricity Consumption
per Unit of GDP refers to the electricity consumption per unit of gross domestic production in a country
or the gross region production in a region in the same reference period. The
formula is:
Electricity Consumption
per Unit of GDP = Total Electricity Consumption / Gross Domestic Production
Energy Consumption per
Unit of Industrial Value-added refers
to the energy
consumption per unit of industrial
value-added in a country or region in the same reference peroid.
The formula is:
Energy Consumption per Unit of Industrial Value-added = Total Energy
Consumption / Industrial Value-added
