NEW ENERGY FROM OLD SOURCE

At present the energy is the result of many complex and different factors, including a world-wide demand for energy: efforts during the recent past to develop new energy resources; delays in the construction of nuclear power plants, automobile changes that increase gasoline consumption. Demand must be moderated, and intensive efforts must be made to expand the overall energy supply.

But energy is available to use in practically unlimited quantities from other sources. Large amount of energy can be received from ocean tides and currents, from tremendous underground steam deposits, from the power of wind and from the hea t of the Sun. Here comes the Sun. The idea of heating houses with warmth of the Sun has become popular in the last few years.

Most solar-heating systems use a black surface to absorb the Sun’s heat. Engineers cover the surface with glass which lets in the rays, but holds heat. The heat is transferred to water that runs through small pipes. The hot water is then circulated through the house. It is estimated that 40 million new buildings will be heated by solar energy by the year 2000. The solar cell is another way to produce power from the Sun. It converts sunlight directly into electricity. These cells are used with great success in space program, but remain far expensive for wide-spread application. In the meantime, solar homes are being built and lived in from California to Connecticut. The next step is mass production of homes, office buildings and schools – all heated by the Sun.

Say whether the following statements are true (T) or false (F). If false, correct them according to the text.

Statement	True	False
1. At present there is no energy problem.
2. During the recent years efforts are being made to develop new energy resources.
3. It is not possible to receive energy from ocean tides and currents.
4. Most solar-heating systems use a white surface to absorb the Sun’s heat.
5. The heat is transferred to water that runs through small pipes.
6. The solar cell doesn’t convert sunlight directly into electricity.
7. The solar cells are cheap.
