a. Look at the pictures, title and subtitles in the text. Think about two questions you would like to ask about alternative energy. Read the text and see if you can answer them. What else did you learn from the text?
b. Read again and complete the gaps (1 – 10) with the correct word formed from the words in brackets. Listen and check, then explain the words in bold.
Alternative energy
64% of the electricity we need comes from 1) ……. (burn) fossil fuels such as oil, gas and coal. These resources pollute and are not 2) …….. (renew), so once we have burned 3) …….. (they) all up, there will be no more. This means that the world MUST find and use alternative sources of energy … FAST! This alternative energy needs to use no fuel and create no waste or 4) …….. (pollute).
Sun (solar power)
Enough of the sun's energy 5) …….. (hit) the Earth every minute to power the world for a whole year! In sunny countries, solar cells can be put on rooftops to convert sunlight 6) …….. (direct) into electricity. We could even build solar power stations like Solar One in California. This uses the sun's heat to make steam, which then drives a 7) …….. (generate) to produce electricity.
Wind (wind power)
We can use the power of the wind by 8) …….. (build) wind turbines. These are tall towers witha big propeller on top. The wind blows the propeller, which turns a generator in order to create electricity. If we build a number of wind turbines together in a 9) ……… (wind) place, we can make a „wind farm” and produce quite a lot of electricity!
Water (hydroelectric power)
A dam can be used to trap a large area of water, like a reservoir or a lake. This water then flows through tunnels in the dam, turns turbines and drives generators to create electricity. Hydroelectric power stations can produce a lot of power very 10) …….. (cheap).

Решение
a. How can we use solar energy? How is the wind power generated? I’ve also learnt about water power.
b.
Alternative energy
64% of the electricity we need comes from 1) burning (сжигание) fossil fuels such as oil, gas and coal. These resources pollute and are not 2) renewable (возобновимые), so once we have burned 3) them (их) all up, there will be no more. This means that the world MUST find and use alternative sources of energy … FAST! This alternative energy needs to use no fuel and create no waste or 4) pollution (загрязнение).
Sun (solar power)
Enough of the sun's energy 5) hits (попадает на) the Earth every minute to power the world for a whole year! In sunny countries, solar cells can be put on rooftops to convert sunlight 6) directly (непосредственно) into electricity. We could even build solar power stations like Solar One in California. This uses the sun's heat to make steam, which then drives a 7) generator (генератор) to produce electricity.
Wind (wind power)
We can use the power of the wind by 8) building (строя) wind turbines. These are tall towers with a big propeller on top. The wind blows the propeller, which turns a generator in order to create electricity. If we build a number of wind turbines together in a 9) windy (ветреном) place, we can make a „wind farm” and produce quite a lot of electricity!
Water (hydroelectric power)
A dam can be used to trap a large area of water, like a reservoir or a lake. This water then flows through tunnels in the dam, turns turbines and drives generators to create electricity. Hydroelectric power stations can produce a lot of power very 10) cheaply (дешево).
pollute (загрязнять) – make dirty
power (питать электроэнергией) – supply with energy
solar cells (солнечные батареи) – converters of sun energy into electricity
convert (преобразовывать) – change smth into a different thing on some purpose
dam (дамба) – a barrier which controls a flow of water
trap (сдерживать) – hold
flows (течет) – streams
