Total Energy Production refers to the total production of primary energy by all energy producing enterprises in the country 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, hydro-power 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.ª¥
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 country 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.ª¥
(1)Final Energy Consumption: It refers to the total energy consumption by material production sectors, non material production sectors and households in the country (region) 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.ª¥
(2)Loss During the Process of Energy Conversion: It refers to the total input of various kinds of energy for conversion, minus the total output of various kinds of energy in the country in a given period of time. It is an indicator to show the loss that occurs during the process of energy conversion.ª¥
(3)Energy Loss: It 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.ª¥
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: ª¥
Elasticity Ratio of Energy Consumption = (Average Annual Growth Rate of Energy Consumption)/( Average Annual Growth Rate of National Economy)ª¥
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:ª¥
Elasticity Ratio of Electricity Consumption = (Average Annual Growth Rate of Electricity)/( Average Annual Growth Rate of National Economy)
