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 a few places 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 build a dam for hydroelectricity

Example:
A: I think that wind power can be an alternative sources of energy
B: Why do you think so?
A: Because our major sources of energy are runnning out while the wind is abudant and unlimited
B: I know It is also clean and safe to the environment However, it is not available when there is no wind
Task 3 Work in groups Express your belief on the increasing use of alternative source of energy in the future, using the ideas from Task 2
A sample:
In my opinion, using the alternative sources will be an indispensable tend in the future because it can help solve the rapid exhausion of major sources of energy The alternative sources such as solar energy, water power, wind power, are clean and safe for our life Besides, they are unlimited and can be renewable Science and technology will develop so fast that there will be more windmills, dams or solar panels set up to creat energy in the coming years I think in the future, the alternative sources will replace sompletely our major sources of energy
