We use many different energy sources to do work for us. Energy sources are classified into two groups - renewable and nonrenewable. Non-renewable energy sources are those that take millions of years to form and will run out some day. It is energy that comes from fossil fuels such as coal, crude oil, and natural gas. Fossil fuels are mainly made up of carbon and were formed millions of years ago. The chemical reaction which takes place when we burn fossil fuels releases carbon compounds such as...

We use many different energy sources to do work for us. Energy sources are classified into two groups - renewable and nonrenewable. Non-renewable energy sources are those that take millions of years to form and will run out some day. It is energy that comes from fossil fuels such as coal, crude oil, and natural gas. Fossil fuels are mainly made up of carbon and were formed millions of years ago. The chemical reaction which takes place when we burn fossil fuels releases carbon compounds such as carbon monoxide and carbon dioxide into the air. Carbon dioxide is one of the green house gases which is contributing to global warming and air pollution. On the other hand, renewable energy sources will never run out, are better for the environment and do not cause pollution. Renewable energy is often called green energy because it is a natural energy, always available and does not have to be formed like nonrenewable energy. The green energy is always there. For example, the Sun consistently shines, water is abundant, and the winds blow throughout the year. The five types include solar, energy from the Sun; geothermal, energy from heat within the Earth; hydroelectric, energy from moving water; biomass, energy from dead plants and microorganisms and finally, energy from the wind.

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...

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

Most of the world’s energy comes from the sun. The sun’s energy is in wood, oil, and other things that people use for energy.People use many sources of energy. Ancient people used only their arms, hands and simple tools until they discovered fire. Later, people learned to use the energy of the wind to sail ships. Then they learned to use animals to do work. In the 18th and 19th centuries, people began to use machines. The first machines used steam. They burned coal to heat water. The hot water...

Most of the world’s energy comes from the sun. The sun’s energy is in wood, oil, and other things that people use for energy.
People use many sources of energy. Ancient people used only their arms, hands and simple tools until they discovered fire. Later, people learned to use the energy of the wind to sail ships. Then they learned to use animals to do work. In the 18th and 19th centuries, people began to use machines. The first machines used steam. They burned coal to heat water. The hot water turned into steam, and the steam engine did the work. Later, people began to use the gasoline engine, and today people are using nuclear energy.
Energy is one of the basic concepts, or ideas, or physics. It is the ability to do work. Without energy we could not live. We need energy to work, and scientists are always looking for new sources of energy.
1.where most of the world's energy from?
2.what did ancient people use before they discover fire?

3.when do people strat using machines?
4.did the first machine use coal?
5.what are scientists trying to look for?

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
