VII. Прочитайте и устно переведите текст. Fuels The chief sources of energy are oil, natural gas, coal, water power and atomic energy. Coal, gas and oil represent energy that has been concentrated by the decay of organic materials. Most fuels are carbon-containing substances that are burned in air. In burning fuels give off heat which is used for different purposes. Fuels may be solid, liquid and gaseous. Solid fuels may be divided into two main groups, natural and manufactured. The first group includes coal, wood, peat and other plant products. The second group includes coke and charcoal obtained by heating coal in the absence of air. Liquid fuels are derived almost from petroleum. Petroleum is found in porous sedimentary rocks where the geologic formation allowed the oil to collect from a wide area. Petroleum is one of the most efficient fuels and raw materials. 32 Of gaseous fuels the most important are those derived from natural gas, chiefly methane, or petroleum. Gas is the most economical and convenient type of fuels. Generally speaking, all types of fuels are of great economic importance as they represent the sources of energy the man uses today.
