What are the main sources of energy in Viet Nam? What types of energy sources will be used in the future? Renewable and non-renewable energy Professor Galton CREATE A MACHINERY DRIVE GENERATE / CONVERT INTO B TURBINES C ALTERNATIVE ENERGY D HOUSES TURN E ELECTRICITY HEAT nuclear wind coal solar biogas natural gas oil hydro 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 clean, safe electricity They will be 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 clean, safe electricity They will be nuclear wind coal solar biogas natural gas oil hydro Answer the questions: How many types of energy sources are mentioned in the text? What are they? What are the disadvantages of hydro and nuclear power? 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? nuclear wind coal solar biogas natural gas oil hydro What does the professor think Vietnam will use more in the future? He thinks Vietnam will use the wind and the sun as alternative sources of energy in the future What types of energy does Vietnam use most? We use non-renewable sources of energy the most but we are increasingly using hydro power Sources of energy oil/ coal/ natural gas hydro nuclear solar wind Types of energy Advantage(s) create energy, generate non - renewable electricity, and drive machinery Disadvantage(s) harmful to the environment Sources of energy oil/ coal/ natural gas hydro nuclear solar wind Types of energy Advantage(s) Disadvantage(s) non-renewable create energy, generate electricity, and drive machinery harmful to the environment renewable renewable generate a great deal of energy/ plentiful renewable convert into electricity, heat or coal the houses/ abundant, clean, safe renewable make electricity/ abundant, clean, safe limited /dams cannot be built in certain areas dangerous not available not available Let’s talk!!! What is its advantage? What type is it? What is its disadvantages? Sources of energy Ask and answer about advantages 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?
