ENERGY AND ITS SOURCES

The consumption of energy is expected to grow. The amount of energy consumed by a country is closely connected with its degree of technological development and industrialization, which are in turn related to the people's standard of living.

Energy can be classified according to its sources. Coal, oil, and natural gas are «fossil fuels» which are extremely useful raw materials. But when they are burned for fuel, harmful pollution may result and there is a great waste of natural resources.

Wood was the main source a hundred years ago. The growth of coal usage in the early 1900s is associated with rapidly increasing industrial development. There followed a great expansion in the consumption of natural gas and fuel oil for heating, electrical generation and especially transportation.

Several conclusions can be made: research and development work to find new sources of energy and ways of increasing efficiency are needed; the new sources of fuels must be fully developed and utilized. Natural gas is a popular source of energy because of its convenience for use and cleanliness in burning. It is generally believed that gas will be the first fossil fuel to be in short supply, and the cost of oil extraction is high.

It is known that much is being done in the world today for the development of non-traditional sources of energy. Without them the earth cannot support its present population. To these sources we can add the energy obtained from water motion and the sun. One of the most promising research is the development of power stations with direct transformation of solar energy into electricity on the basic of photo-effect. Solar power is often mentioned as the logical alternative. The amount of radiant energy that reaches the earth's surface is more than what is needed. For the generation of electricity, there are serious problems to be solved. To collect and concentrate the energy by reflectors and converters of present efficiency is the major difficulty. The efficiency of a solar power station is considerably reduced because of the limited time of its work during the year. There remain many technological problems in this area.

Man is consuming the remaining resources at a rate that they may last only a few centuries. Efforts to eliminate the extravagant waste of energy are needed. Several conclusions can be made: research and development work to find new sources of energy and ways of increasing efficiency are needed; the new sources of fuels must be fully developed and utilized. And we must give a serious consideration nuclear energy, i.e. the energy from nuclear reactions, the burning of nuclear fuel.
