(1)终端能源消费量：指一定时期内生产和生活消费的各种能源在扣除了用于加工转换二次能源消费量和损失量以后的数量。

(2)能源加工转换损失量：指一定时期内投入加工转换的各种能源数量之和与产出各种能源产品之和的差额，是观察能源在加工转换过程中损失量变化的指标。

(3)能源损失量：指一定时期内能源在输送、分配、储存过程中发生的损失和由客观原因造成的各种损失量，不包括各种气体能源放空、放散量。

能源生产弹性系数指研究能源生产增长速度与国民经济增长速度之间关系的指标。计算公式为：

能源生产弹性系数＝能源生产总量年增长速度／国民经济年增长速度

国民经济年增长速度，可根据不同的目的或需要，用国民生产总值、国内生产总值等指标来计算，本年鉴是采用国内生产总值指标计算的。

电力生产弹性系数指研究电力生产增长速度与国民经济增长速度之间关系的指标。计算公式为：

电力生产弹性系数＝电力生产量年增长速度／国民经济年增长速度

能源消费弹性系数指反映能源消费增长速度与国民经济增长速度之间比例关系的指标。计算公式为：

能源消费弹性系数＝能源消费量年增长速度／国民经济年增长速度

电力消费弹性系数指反映电力消费增长速度与国民经济增长速度之间比例关系的指标。计算公式为：

电力消费弹性系数＝电力消费量年增长速度／国民经济年增长速度

能源加工转换效率指一定时期内能源经过加工、转换后，产出的各种能源产品的数量与同期内投入加工转换的各种能源数量的比率。它是观察能源加工转换装置和生产工艺先进与落后、管理水平高低等的重要指标。计算公式为：

能源加工转换效率＝(能源加工、转换产出量／能源加工、转换投入量)×100%

单位地区生产总值能耗指一定时期内，一个国家或地区每生产一个单位的地区生产总值所消耗的能源。计算公式为：

单位地区生产总值能耗=能源消费总量/地区生产总值

单位工业增加值能耗指一定时期内，一个国家或地区每生产一个单位的工业增加值所消耗的能源。计算公式为：

单位工业增加值能耗=工业能源消费量/工业增加值

单位地区生产总值电耗指一定时期内，一个国家或地区每生产一个单位的地区生产总值所消耗的电力。计算公式为：

单位地区生产总值电耗=全社会用电量/地区生产总值

Total Energy Production refers to the total production of primary energy by all energy producing enterprises in the region in a given period of time. It is a comprehensive indicator to show the capacity, scale, composition and development of energy production of the region. 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 Domestic Energy Consumption refers to the total consumption of energy of various kinds by material production sectors, non material production sectors and households in the region 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:

(1) Final Energy Consumption: It refers to the total energy consumption by material production sectors, non material production sectors and households in the region (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.

(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 region in a given period of time. It is an indicator to show the loss that occurs during the process of energy conversion.

(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.

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= Annual Growth Rate of Energy Production/ Annual Growth Rate of National Economy

The annual growthrate of the national economy can be shown by the gross national product, gross domestic product and other indicators, depending upon the purposes or needs. The gross domestic product is used in calculation of the ratio in this chapter.

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 electricity production should be higher than that of the national economy.The formula is:

Elasticity Ratio of Electricity Production= Annual Growth Rate of Electricity Production/ 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= Annual Growth Rate of Energy Consumption/ 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= Annual Growth Rate of Electricity/ Annual Growth Rate of National Economy

Efficiency of Energy Processing and Conversion refers to the ratio of the total output of energy products of various kinds after processing and conversion and the total input of energy of various kinds for processing and conversion in the same reference period. It is an important indicator to show the current conditions of energy processing and conversion equipment, production technique and management. The formula is:

Efficiency of Energy Processing & Conversion=(Output of Energy After Processing & Conversion/Input of Energy for Processing & Conversion)×100%
