Task 1. The following statements list some advantages and disadvantages of various sources of energy. Read and tick () the appropriate box A ( for the advantages ) or D (for the disadvantages ), then compare the results with partner’s. A D 1.Fossil fuels will be exhausted within a relatively short time .  2.Geothermal heat is available only in the few place in the world.  3.If the wind does not blow, there is no wind energy.  4.Water power provides energy without pollution.  5.A nuclear reactor releases radiation which is dangerous to the environment.  6. Solar energy is not only plentiful and unlimited but also clean and safe.  7.It is expensive to built a dam for hydroelectricity. 
Task 2: Work in pairs. Talk with your friend about the advantages and disadvantages of using each alternative sources of energy , using the suggestions from Task 1. Why do you I think that wind think so? power can be an alternative source of energy.......

Sources of Advantages Disadvantages energy Nuclear energy It is unlimited It can be dangerous Geothermal It is available It is only available in heat some places Solar energy It is not only plentiful It is only possible and infinite but also during the day time clean and safe It is clean If the wind doenn’t Wind power and unlimited blow,there is no wind no energy. It is clean and It is expensive to Water power unlimited built a dam for hydroelectricity
