交通运输系统使用的能源主要是矿物燃料(石油、天然气和煤),而在公路运输中主要使用的是石油。根据最乐观的估计,地球上的石油储量按现在的消耗速度只能维持大约150年的使用.如果世界状况没有特别大的变化,能源消耗速度在未来的年份还会继续加大.目前数亿机动车辆消耗世界年开采石油量的近1／2。而我国又是一个石油资源并不丰富的国家。近年来随着我国交通建设和公路运输行业的迅猛发展,交通运输中的能源消耗越来越大,因此增强节约能源意识,如何节约能源已经成为交通运输行业亟需解决的首要问题。
The energy used in transportation systems is mainly fossil fuels (oil, natural gas and coal), while oil is mainly used in road transport. According to the most optimistic estimates, the oil reserves on Earth can only be maintained for about 150 years at the current rate of consumption, and if there are no significant changes in the world situation, the rate of energy consumption will continue to increase in the coming years. Motor vehicles consume nearly 1/2 of the world’s annual oil production. Our country is another country that does not have rich oil resources. In recent years, with the rapid development of transportation construction and road transportation in our country, the energy consumption in transportation becomes larger and larger. Therefore, to enhance energy conservation consciousness and how to save energy has become the most important problem to be solved urgently in the transportation industry.
