Explanatory
Notes on Main Statistical Indicators
Total Energy Production refers to the total production of primary energy by all energy
producing enterprises in the region in a given period of time. It is a
comprehensive indicator to show the capacity, scale, composition and
development of energy production of the region. 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 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:
(1)Final
Energy Consumption: It refers to the total energy consumption by material
production sectors, non material production sectors and households in the
region(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 region in a given period of time. It is an
indicator to show the loss that occurs during the process of energy
conversion.
(3)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
¡ÂAverage
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 ¡ÂAverage
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 ¡ÂAverage
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
¡ÂAverage
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¡ÂInput
of Energy for Processing & Conversion¡Á100%
