能源是一种提供能量的物质,如化石燃料、核能、可再生能源等,要计算综合能耗需将各种能源折算为标准燃料(煤当量、油当量或气当量)。世界能源消耗量中,化石燃料(石油、煤炭、天然气等天然资源)是最主要的能源,中国人均能源消耗量18,608 kWh(2008年)。化石燃料属于耗竭性能源,其供应量不足会造成能源危机,特别是从石油提炼出来的汽油影响最大,因为石油供应不足已出现过三次全球性的石油危机。电能(Electric Energy)是一种很容易传输的能量形式,以有线或无线的形式传输。电的来源非常丰富,主要来自热能(煤炭和天然
Energy is a substance that provides energy such as fossil fuels, nuclear energy, renewable energy, etc. All energy sources need to be converted into standard fuels (coal equivalent, oil equivalent or gas equivalent) to calculate total energy consumption. Among the world’s energy consumption, fossil fuels (natural resources such as oil, coal and natural gas) are the most important energy sources. China’s per capita energy consumption is 18,608 kWh (2008). Fossil fuels are an exhaustible source of energy, and their lack of supply can create an energy crisis, especially where petrol extracted from oil has the biggest impact because of three global oil crises that have taken place in the oil supply. Electric Energy is a form of energy that is easily transmitted and transmitted in wired or wireless form. The source of electricity is very rich, mainly from heat (coal and natural
