【能源消费总量】指一定时期内全国(地区)物质生产部门、非物质生产部门和生活消费的各种能源的总和,是观察能源消费水平、构成和增长速度的总量指标,能源消费总量包括原煤和原油及其制品、天然气、电力等。不包括低热值燃料、生物质能和太阳能等的利用。能源消费总量分为三部分,即终端能源消费量、能源加工转换损失量和损失量。

(1)终端能源消费量:指一定时期内全国(地区)物质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:指一定时期内全国(地区)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。它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。


【Total Domestic Energy Consumption】refers to the total consumption of energy of various kinds by material production se-ctors,non-material production sectors and households in the coun-try (region)in a given period of time.It is a comprehensive indica-tor to show the scale,composition and development of energy con-sumption.The total energy consumption includes that of coal,crude oil and their products, natural gas and electricity.However,it exclu-des the consumption of fuel of low calorific value, bioenergy 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 produc-tion sectors and households in the country (region)in a given peri-od of time,but excludes the consumption in conversion of the pri-mary 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 country in a given period of time.It is an indicator to show the loss that occurs during the process of energy conversion.

(3)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.
