What is this video clip about?watch the video2. What do you know about the energy ?BEFORE YOU READActivity 1: Choose the main idea.WHILE YOU READFossil fuels is non-renewable.We need energy to cook meals, to run machines,....New sources of energy, though with some disadvantages, are great to replace fossil fuels in the future.132Activity 2: Scan the passage and write down the advantage (s) and 	disadvantage (s) of each alternative source of energy.WHILE YOU READSources of energyAdvantage(s)Disadvantage(s)Nuclear powerSolar energyWater powerWind powerGeothermal heatSources of energyAdvantage(s)Disadvantage(s)Nuclear energyGeothermal heatParagraph 2One alternative source is nuclear energy. Nuclear energy can provide enough electricity for the world’s needs for hundreds of years, but it can be very dangerous. Another alternative source of energy is geothermal heat, which comes from deep inside the earth. Scientists use this heat to make energy. However, this energy is available only in a few places in the world.It’s unlimited. (P2-L1,2)It can be very dangerous. (P2-L3)It’s available in only a few places. (P2-L5,6)It is available. (P2-L4)Paragraph3The sun, water, and the wind are other alternative sources of energy. The wind turns windmills and moves sailboats. It is a clean source of energy, and there is lots of it. Unfortunately, if the wind does not blow, there is no wind energy. When water moves from a high place to a lower place, it makes energy. This energy is used to create electricity. Water power gives energy without pollution. However, people have to build dams to use this energy. And dams cost a lot of money, so water energy is expensive.Sources of energyAdvantage(s)Disadvantage(s)Wind powerWater powerIt’s clean and unlimited. (P3-L2,3)If the wind does not blows, there is no wind energy. (P3-L3,4)It’s clean and unlimited.(P3-L6)It’s expensive. (P3-L7,8)Paragraph 4The sun releases a large amount of energy every day. This energy can be changed into electricity. Many countries use solar energy for their day life. Solar panels on the roofs of houses can create enough energy to heat or cool an entire house. Solar energy is not only plentiful and infinite but also clean and safe.Sources of energyAdvantage(s)Disadvantage(s)Solar energyIt’s plentiful, infinite, clean and safe.
