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
Domestic Energy Consumption refers to the total consumption of energy of national industry and
households in the province 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 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.
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 Product in a
country or the Gross Regional Product in a region in the same reference period.
The formula is:
