Natural Energy
A One blow for energy
In countries like the UK. one obvious answer is to harness natural resources to make electricity. Trying to use the sun is one possibility, but the UK is hardly the place to rely on sunshine, as it can often go weeks without a glimpse of the sun in the sky. However, one thing that the UK has plenty of is wind - especially on all the small hills that arc found in many parts of the countryside. Wind farms, which consist of huge wind turbines placed on ridges and the tops of hills, are being set up across the country. These turbines look like giant sails or windmills with great big blades turning round. Some people think these structures look ugly and spoil the views in the countryside, but if it reduces the cost of energy bills, surely ittasks worth it.
В Sun worship
The largest solar farms in the world arc found in the west of the USA. in states like California. Arizona and New Mexico, but nowadays countries like China. India and even Germany arc constructing equally big solar farms. Energy from the sun is nothing new - in fact many of our ancestors worshipped the sun. as they knew it was the source of energy and life. Solar panels try to harness the rays of the sun and convert these into usable energy. One clear advantage is that ittasks renewable energy - ittasks not going to run out. However, there are some disadvantages, and some of those arc only just coming to light.
The biggest of these is connected to the panels that arc used. Most of these are constructed of silicon, which has a lifespan of around 25 years. The problem is v/hat to do with the silicon and the panels once they are no longer functioning. Unfortunately, the material is dangerous, and getting rid of it safely is starting to become a bit of a headache.
C Just hot water
In Iceland another source of energy is readily available and relatively cheap. Originally this source of energy was only seen as a tourist attraction and people would visit Iceland just to see these wonders of nature in action. Of course, what we are talking about are the geysers which currently provide 20% of all the countrytasks electricity - and this is set to rise in the coming years. More than a century ago some farmers used the steam from the hot springs to heat their houses, but it wasntaskt until the oil crisis of the 1970s that the Icelandic government saw the potential and started investing in geothermal power. Ittasks cheap, clean and reliable energy which will never run out - and perfect for the environment.
A Read the text and match the pictures (1-4) with the correct paragraphs (A-C). There is one extra picture.
В For each of these sentences, choose the correct energy type: geothermal, solar or wind.
1 This type of energy is used a lot in Iceland.
2 There might be some problems connected to this type of energy.
3 This type of energy has been in use for more than 100 years.
4 The best way to harness this energy is to build things on high places.
5 According to the text, this type of energy is already popular in many countries.
6 Not everyone is happy with the way this type of energy makes things look.
C Match the words in bold in the text with these definitions.
1 change something from one system or use to another
2 make something worse or less attractive
3 possible or likely in the future
4 remove something from somewhere
5 something that causes you lots of problems
6 get control of something to use it for a purpose
7 working
8 see something for a very short amount of time or not completely
9 very surprising
10 a difficult or dangerous situation
D Choose a text and read it aloud.
Imagine that you are preparing a project with your friend. You have found some interesting material for the presentation and you want to read it to your friend. You have 1.5 minutes to read the text silently, then be ready to read it aloud. You will not have more than 1.5 minutes to read it.
E Work in pairs. Discuss these questions.
1 Why is it important to look at alternative sources of energy?
2 Which type of energy do you think is the best? Why?
3 What other types of energy do you know about?
