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
Read the passage below and an answer the question :
We can develop alternative sources of energy,and unless we'll never succeed.instead of burning fossil fuels we should be concentrating on more economic uses of electricity because electricity can be produced from any source of energy. If we didn't waste so much energy,our resources would last longer. We can save more energy by conservativation than we can produce for the same money. Unless we do research on solar energy wind power tidal power hydroelectric plants.... Our fossil fuels will run out and we'll all freeze starve to dealth . Many countries are spending much more time and money on research because the energy from the sun the waves and the winds last forever.we really won't survive unless we start working on cleaner safer scour of energy .
1 Can electricity be produced from any sources of energy?
Yes, it can.
2 What would happen if we didn't waste so much energy?
If we didn't waste so much energy, our resources would last longer.
3 Why are many countries spending much more time and money doing research on energy from the sun the waves and the wind?
Because the energy from the sun the waves and the winds last forever.
4 What will happen unless we start working on cleanr and safer sources of energy?
We really won't survive unless we start working on cleaner and safer scources of energy
1. Most of the world's energy comes from the sun.
2. Ancient people used only their arms, hands, and simple tools until they discovered fire.
3. In the 18th and 19th centuries.
4. Yes, they did.
5. Scientists are always looking for new sources of energy.
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
1. Solar -> solar energy: năng lượng mặt trời
2. biogas ~ khí sinh học
3. natural gas ~ khí tự nhiên
