G-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: |
(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)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% |
