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, process,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.
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:
Elasticity Ratio
of Energy Production =
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 Electricity Production =
Elasticity Ratio of Energy
Consumption
is the ratio between the growth rate of energy
consumption and the growth rate of the national economy. The formula is:
Elasticity Ratio
of Energy Consumption =
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:
Elasticity Ratio
of Electricity Consumption =
