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 by material production sectors,
non material production sectors and households in the city 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.
Final Consumption
of Energy
refers to the
total energy consumption by material production sectors, non material
production sectors 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 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 measured by indicators such
as the Gross National Product and the Gross Domestic Product, depending on the
purposes or needs. The Gross Domestic Product has been used in the calculation
of the ratio in this Yearbook.
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 the 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 |
