Production and Consumption of Energy
I. The data in this chapter cover
mainly the energy production and consumption and their composition, the
elasticity ratio of energy production and consumption, the overall balance of
energy and the balance by the variety of energy, the consumption of energy by
sector and by main variety, efficiency of energy conversion and the consumption
of energy for residential use.
II. The national energy balance in
this chapter is compiled by the Department of Industry and Transport
Statistics, NBS on the basis of data from surveys and from input-output tables.
III. Coverage and calculation of
data:
(1) The data on the production of
primary energy are the same as the concerned data of the industrial statistics.
(2) The elasticity ratio of energy
production is calculated as the quotient of the growth rate of energy
production divided by the growth rate of GDP; and the elasticity ratio of
energy consumption is calculated as the quotient of the growth rate of energy
consumption divided by the growth rate of GDP.
(3) In the energy balance, the data
on the imports and exports are data from the customs statistics. The refueling
by Chinese ships and airplanes abroad is included in the imports. The refueling
by foreign ships and airplanes in China is included in the exports. The
coefficient for conversion of electric power into the standard coal equivalent
is calculated according to the average consumption of coal for generating
electricity.
(4) In the table on the efficiency of energy conversion,
the coefficient for conversion of electric power into the standard coal
equivalent is calculated on the basis of heat value equivalent. One kwh is
equal to 0.1229 kg SCE.
