Energy
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%
