纵观20世纪的社会和经济发展,一个突出的特点是,电力的使用已渗透到社会经济、生活的各个领域,由于电力具有便于转换能源形式,能高度集中和无限划分,清洁干净和易于控制,可大规模生产和远距离输送等特性,使电力发展和应用的程度,即一个国家的电气化程度成为衡量其社会现代化水平高低,以及物质文明和精神文明高低的重要标志之一。特别是在进入以信息、电子、生物技术为代表,从集中到分散,从等级结构到网络结构,从简单选择到多种选择的21世纪,电力将继续发挥其他能源形式所不能替代的作用,而且我们对电力的依赖程度将更高,对电力供应的数量和品质也将提出更大、更高的要求。
A striking feature of the social and economic development of the 20th century is that the use of electricity has penetrated into all fields of social economy and life. Due to its ease of conversion, power can be highly concentrated and unlimitedly divided, cleanly cleaned and easily controlled , Which can be mass-produced and transported over long distances, make the degree of electric power development and application, that is, the degree of electrification of a country become one of the most important indicators to measure the level of its social modernization, as well as the level of material civilization and spiritual civilization. Especially in the 21st century, which is represented by information, electronics and biotechnology, from concentration to decentralization, from hierarchical structure to network structure, from simple choice to multiple choice, power will continue to play an irreplaceable role in other energy forms, And our dependence on electricity will be even higher, and the number and quality of power supply will also make greater and higher demands.
