8. Rewrite the following text and translate 1-3 paragraphs of the text. Alternative energy

Energy comes in many forms — heat, light, sound, electrical, and mechanical. There is no shortage of energy in the world. If you stand on the beach on a windy day you can see the strength of the wind and the waves, and the powerful burning light from the sun. The problem is how to convert this energy into the type of energy we need most today — electricity.

A device that converts one form of energy to another is called a generator. The traditional generator converts heat energy from coal or gas into electrical energy. The generators of the future will harness renewable forms of energy in a similar way. Wind power has been used for hundreds of years in the form of the old-fashioned windmill, which converted one form of mechanical energy (wind) into another (the milling process). The modem version of the windmill is the aerogenerator, which converts wind energy into electrical energy.

The aerogenerator is relatively cheap and quick to build. It would take about, two years to build a wind-powered electricity generating station, compared with 10 years for a power station based on fossil fuels. Wind power is clean and plentiful, and an aerogenerator does no damage to the environment. But aerogenerators are noisy, and the electricity cannot be stored easily for calm days. Wind power cannot, of course, be used in places where there is not much wind!

Aerogenerators are best, sited in coastal or mountainous areas. The Aran Islands are three tiny islands off the coast of Ireland that supply all their own energy needs from aerogenerators.

9. Answer the following questions:

1. What forms of energy do you know?

2. How we can call the device that converts one form of energy to another?

3. Is the aerogenerator environment friendly device?
