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 |
