Explanatory Notes on Main Statistical Indicators
Total
Energy Production
refers to the total production of primary energy by all energy producing
enterprises in the city 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, hydropower 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 of national
economy industries and residents in the city in a given period of time. Total
energy consumption can be divided into three parts: final energy consumption,
loss during the process of energy conversion, and energy loss.
Final Consumption of Energy refers to the
total energy consumption by various industries and households in the city 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.
Final
Consumption of Energy
refers to the total energy consumption by various industries and
households in the city 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.
Loss During the Process of Energy Conversion
refers to the total input of various kinds of energy for conversion, minus
the total output of various kinds of energy in the city in a given period of
time. It is an indicator to show the loss that occurs during the process of
energy conversion.
Energy
Loss
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 the ratio between the growth rate of energy production and the
growth rate of the national economy. The formula is:
The gross domestic products
(GDP) is used to calculate the average annual growth rate of national
economy.
Elasticity
Ratio of Electricity Production
is the ratio between the growth rate of electricity production and the
growth rate of the national economy.
The formula is:
Elasticity
Ratio of Energy Consumption
is the ratio between the growth rate of energy con- sumption and the growth rate of the national economy. The formula is:
Elasticity
Ratio of Electricity Consumption
is the ratio between the growth rate of electricity consumption and
the growth rate of the national economy.
The formula is:
