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 cannot be built in certain areas. Nuclear power is dangerous.
3.Why do you think the wind and the sun are called alternative sources of energy?
Because they are natural sources of power and we use them instead of non-renewable sources to get the electricity we need.
4.What types of energy does Viet Nam use most?
We use non-renewable sources of energy the most but we are increasingly using hydro power.
5.What does the professor think Viet Nam will use more in the future?
He thinks Viet Nam will use the wind and the sun as alternative sources of energy in the future
In the modern world, people depend on energy to power their everyday lives. A wide range of power-run devices and modern conveniences (1) are taken for granted, and although it may seem that we will not be in danger of living without those conveniences, the fact is that many supplies of energy are running out rapidly. Scientists are constantly (2) searching for new sources of energy to keep modern society running. Whether future populations will continue to enjoy the benefits of abundant energy will depend (3) on the success of this search. Coal, oil and natural gas are now being used widely. (4) However, not only are supplies of , these supplies are limited, and they are a major source of pollution. Therefore, the existing alternative energy sources must be improved or futher explored and developed. These include nuclear, water, solar, and wind power, as well as energy from new, (5) nonpolluting types of fuels types of fuels. Each of these, however, has advantages and disadvantages.

1. Non - renewable sources are being used up. T
2. Many poor people in developing countries do not have little electricity. F
3. Biogas is a new source of energy available for poor people. T
4. Biogas creates a lot of smoke. F
5. The new energy source is not costly T
Energy is fundamental to human beings. Many poor people in developing countries do not have modern sources of energy like electricity or natural gas, with which their life can be improved.
People who live in mountainous areas have to gather wood for fuel. This takes a lot of time. For many people living in rural areas, biogas is the largest energy resource available. The main use of biogas is for cooking and heating, but it can also provide energy for public transport. As biogas is smoke-free, it helps solve the problem of indoor air pollution. Moreover, it’s made from plant waste and animal manure. They cost almost nothing.
The tendency to use renewable energy sources in developing countries is on the increase as non-renewable ones are running outệIn the future, the wind and the sun will be used as the most important environmentally friendly energy sources.
1. Non - renewable sources are being used up. (T)
2. Many poor people in developing countries do not have little electricity. (T)
3. Biogas is a new source of energy available for poor people. (T)
4. Biogas creates a lot of smoke. (F)
5. The new energy source is not costly. (T)
We are looking for cheap, clean, and effective sources of energy. These types of energy won’t cause pollution or waste natural resources. It will be provided freely by the sun. One percent of the solar energy that reaches the earth will be enough to provide electricity for the whole population of the world. Solar energy will be used by many countries around the world. Solar panels will be placed on the roofs of houses and other buildings and the sun’s energy will be used to heat water. The energy will be stored for a long time. We hope that by using solar energy the problem of the energy shortage will be solved.
1. What types of energy are we looking for?
_We are looking for cheap, clean, and effective sources of energy
2. What will we use the sun’s energy for?
_____ The sun’s energy will be used to heat water
3. How long will the energy be stored?
__________The energy will be stored for a long time
Read the following passage and decide if it is T or F
Many people still believe that natural resources will never be used up. Actually, the world's energy resources are limited. Nobody knows exactly how much fuel is left. However, we also should use them economically and try to find out allternative sources of power. According to Professor Marvin Burnharrm of the New England Institude of Technology, we have to start conserving coal. oil and gas before it is too late; and nuclear power is the only alternative.
However, many people do not approve of using nuclear power because it's very dangerous.What would happen if there was a serious nuclear accident? Radioactivity causes cancer and may badly affect the future generations.
The most effective thing ia that we should use natural resources as economical as possible.
1. We don't know how much fuel is left ......T.............
2. According to Professor Marvin Burnharrm , solar energy will be used as a subtitute for natural resources ........F.............
3. Radioactivity from nuclearpower causes caner and may have bad effect on the future generations .......T................
4. Natural resources should be used as much as possible ........F............
It’s hard to (1) believe that just 200 years ago our main energy source was wood. Now we have a wealth of energy sources to choose from, including a growing range of (2) renewable energy technologies.
But what does the future hold? How can we keep (3) supplying energy to an ever-growing population? How much will it cost?
And what impact will the energy choices we make have on our living conditions and our planet?
In a report this year, the Internet Energy Agency experts electricity generation from renewable energy (4) sources to increase from 21 percent in 2012 to 33 percent by 2040. Morever, as battery technology inproves, it will be better able to support renewable energy sources, such as (5) solar and wind power.
Innovation in energy storage has already resulted in graphene technology used in batteries, which may be able to store more energy than existing lithium batteries.
Almost all our energy comes from oil, coal, and natural gas. We call them fossil fuels. The earth’s fossil fuels are running out. What will happen when there is no coal, oil and gas on earth?
Scientists are trying to find and use other alternative sources of energy. We can use energy from the sun, the wind, and the water.
Solar energy is unlimited. The sun supplies all the energy used to grow plants, to evaporate water for rain, and to maintain the temperature of the planet. All are necessary for human life. If we are able to collect solar energy, we will be sure to have this abundant source of power.
