NON - TRADITIONAL RENEWABLE SOURCES OF ENERGY
1. Now we are using traditional power sources such as oil, natural gas and coal, wind and water power. The consumption is more than 50 billion barrels per year. Scientists understand that if mankind consumes natural resources with the same rate, these resources will exhaust 1 in a few hundred years. The amount of natural resources on Earth is not unlimited. That is why it is so important to use such renewable sources of energy as the sun, wind, ocean tides, currents, geothermal energy and others. Research is being carried out in these fields.
2. One of the most promising researches is the development of power stations with direct transformation of solar energy into electricity on the basis of photo effect. It was Russia that was the first in the world to develop and test a photoelectric battery of 32,000 volts and effective area of only 0.5 sq.m., which made it possible to concentrate solar radiation. This idea is now being intensively developed in many countries.
3. However, the efficiency of a solar power station is considerably reduced because of the limited time of its work during the year. But it is possible to improve the efficiency of solar power stations by developing different combinations of solar power stations and traditional ones – thermal, atomic and hydraulic. Today some engineers are working at the problem of developing electric power stations with the use of a thermal - chemical cycle.
4. In Kamchatka there are geothermal power stations operating on hot water - steam from the depths of about a kilometer. In some projects water will be heated by the warmth of volcanoes at a depth of four - five km. Several big companies show great interest towards windmill
5. The installation of the smallest one, ranging from 100 to 2,000 kilowatts would provide sufficient electricity to power several homes; the largest could provide electricity to a small village. It is important that all these advances in developing new sources of energy and improving the old ones help to solve the energy problem as a whole and they do not have negative effects on the environment.

VII. Прочитайте вопрос к тексту. Из приведенных вариантов ответа укажите номер предложения, содержащего правильный ответ на поставленный вопрос:
Why do some big companies show great interest towards windmills?
1. Windmills do not have negative effects on the environment.
2. Windmills improve the efficiency of solar power stations.
3. Windmills would provide sufficient electricity to power homes and villages.
