Are you looking for a cheap, clean, effective source of power that doesn't cause pollution or waste natural resource? Look no further solar energy from the Sun
At present, most of our electricity comes from the use of coal and gas, oil or nuclear power. This power could be provided by the Sun. One percent of the solar energy thet reaches the Earth is enough to provide power for the total population
Many countries are already using solar energy. Solar panels are plaaced on the roofs of a house and the Sun's energy is used to heat water. The energy can be stored a number of days, so or cloudy days you can use solar energy, too
Questions
1. Is the solar energy an effective source os power?
=>Yes,it is
2.Where are the solar panels placed?
=>They are placed on the roof of a house.
3.Is the solar energy used in Vietnam now?
=>Yes,it is
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

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.

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
Our non-renewable energy sources such as coal, oil, and natural gas will (1) _______run___ out of in the future.
