Explanatory Notes on Main Statistical Indicators
Total Energy Production refers to the total production of primary
energy by all energy producing enterprises in the province in a given period of
time. It is a comprehensive indicator to show the capacity, scale, composition
and development of energy production of the province. 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 Energy Consumption refers to the total consumption of energy
of various kinds by the production sectors of the economy and the households in
a given period of time. It includes the primary kinds of energy such as coal,
crude oil, natural gas, hydro-power, nuclear power, wind power, solar power,
geothermal power and bio-energy; the secondary kinds of energy and their
products which are transformed from the primary energy such as washed coal,
coke, coal gas, electricity, heating, and petroleum products; and other kinds
of fossil energy, renewable energy and new energy. The renewable energy,
including hydro-power, wind power, solar power, geothermal power and bio-energy,
refers to the part attained with some given technical means and used for
commercial purposes. Total energy consumption can be divided into three parts: end-use
energy consumption, loss during the process of energy conversion and energy
loss.
(1) End-use Energy
Consumption: It refers to the total energy consumption by material production
sectors, non material production sectors and households in the province 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
province 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.
