2. Energy Crisis This phrase usually refers to a critical shortage in the supply of energy-producing fuels. Such as gas, oil, and coal. During the early 1970 ’ s, the demand foe petroleum increased sharply, and western countries depended heavily on improved supplies. The situation became worse during the ARAB-Israeli war of 1973., when the Arab nations reduced oil production and embargoed oil shipments to the United States and other countries that supported Israel, causing an acute energy shortage in these countries during the winter of Information related to the text

Exercise IV. Dictation Only a few century ago, people ’ s energy supply was made up almost entirely of wood and water. Wood was burned to heat homes and to cook food. Water was used to turn grinding stones. People had not yet discovered the vast underground reserves of petroleum. They had not discovered electricity. Today our energy supply consists mostly of coal, petroleum, and natural gas. These, in turn, produce electricity, which runs machines, heats and
cools buildings, and does many other jobs for us. However, these fuels will not lest for ever. Moreover, in some places, electricity is in short supply. Some scientists believe solar energy is the only kind which can meet the world ’ s enormous need for power. The problem has been to find a way to use the tremendous power which the earth receives from the sun every day.
