Talk about the advantages and disadvantages of each type of energy source example • Hydro power is a renewable source of energy because it come from water.. It is cheap and plentiful?[r]
Student: Cao Thi Hong Loan Discuss What are the main sources of energy in Vietnam? What type of energy sources will be used in the future? Unit 10 Sources of energy lesson Skills I vocabulary • • • • • • • Create= generate Replace Turn turbines Convert into Great deal of= a lot of Alternative Fossil fuels :tạo ra,sản xuất : thay : làm quay tua bin :chuyển hóa thành : nhiều, nhiều :thay : nhiên liệu hoá thạch Read the text carefully in mins Dear guests, I’d like to talk to you today about renewable and non-renewable energy Fossil fuels are non-renewable energy sources They include oil, coal, and natural gas They can be used to create energy, generate electricity, or drive big machinery Unfortunately, they are harmful to the environment Viet Nam still relies mostly on non-renewable energy sources, however, hydro power is increasingly used here too Hydro and nuclear power can generate a great deal of energy They are renewable and plentiful However, hydro power is limited because dams cannot be built in certain areas Nuclear power can provide enough electricity for the world’s needs, but it is dangerous The sun and the wind are other alternative sources of energy The wind turns turbines to make electricity Solar power can be converted into electricity It can be used to heat or cool our houses Although there are some disadvantages, these alternative energy sources can offer abundant amounts of Read the text and check: (Ex / p 44) What are the main sources of energy in Viet Nam? 2, What types of energy sources will be used in the future? Match the verbs with the nouns: (Ex 3a / p 44) CREATE A MACHINERY DRIVE B TURBINES GENERATE C ENERGY TURN D HOUSES HEAT E ELECTRICITY b.Answer the questions 1.How many types of energy sources are mentioned in the text? What are they? 2.What are the disadvantages of hydro and nuclear power? 3.Why you think the wind and the sun are called alternative sources of energy? 4.What types of energy does Vienam use most? What does the professor think VietNam will use more in the future • 1.How many types of energy sources are mentioned in the text? What are they Two, they are renewable and non-renewable 2.What are the disadvantages of hydro and nuclear power? Hydro power is limited because dams can not be built in certain areas Nuclear power is dangerous 3.Why you think the wind and the sun are called alternative sources of energy? Because they are natural sources of power and we use then instead of non-renewable sources 4.What types of energy does Vienam use most? We use non-renewable source of energy the most but we are increasingly using hydro power What does the professor think VietNam will use more in the future He think VietNam we use the wind and the sun as althernative sources of energy in the future Ask and answer about adantages and disadvantages of energy sources A: What type of energy is oil? B: It is non-renewable source of energy, because it can not easily be replaced A: What are its advantages and disadvantages? B: It can be used to power machinery But It also pollutes the environment Sources of energy Types of energy Advangtage(s) Disadvantage(s) oil/ coal/ natural gas nonrenewable create energy generate electricity drive machinery harmful to the environment hydro renewable nuclear renewable generate a great deal of energy solar renewable converted into electricity, heat or coal the houses wind renewable make electricity can not build dams dangerous not available not available Let’s talk!!! What type is it? What is its advantage? What is its disadvantages? Sources of energy Sources of energy oil/ coal/ natural gas hydro hydro Types of energy Advangtage(s) Disadvantage(s) non-renewable create energy generate electricity drive machinery harmful to the environment renewable renewable can not build dams in certain Can not built dams in certain areas generate a great deal of energy Generate a great deal of energy areas dangerous nuclear renewable solar renewable converted into electricity, heat or coal the houses not available wind renewable make electricity not available A: What type of energy is oil? B: It is non-renewable source of energy, because it can not easily be Comes from water replaced A: What are its advantages and disadvantages? B: It can be used to power machinery But It also pollutes the environmen Talk about the advantages and disadvantages of each type of energy source example • Hydro power is a renewable source of energy because it come from water It is cheap and plentiful Unfortunately, dams can only be built in certain areas Home work Learn by heart new words Do reading (workbook) Prepare for next lesson: skills2 ...Discuss What are the main sources of energy in Vietnam?
