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 c...

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.

As the use of alternative energy sources increases, the consumption of the Earths fossil fuels will also decrease. One watt of energy that is used by solar cells is one less watt used by power plants burning oil or coal.

As the use of alternative energy sources increases, the consumption of the Earth's fossil fuels will also decrease. One watt of energy that is used by solar cells is one less watt used by power plants burning oil or coal. If society hopes to see the next generation have the resources needed to heat homes and drive cars, alternative energy sources are needed today.

Fossil fuel is the most common source of energy today, but it is not considered clean energy. There are various other sources of alternative energy that must be incorporated if the next generations are expected to have energy. Water, wind, the internal heat of the Earth, and the sun are all being used to create energy. Geothermal energy and solar energy are more common. Homes are being heated and cooled, cars are being driven, and electricity is used all from these various alternative sources of energy. All are examples of clean energy, which is better for the environment because it does not cause pollution.

Read the passage and decide if these statements are True or False.

	Đúng	Sai
1. The consumption of fossil fuels will decrease since alternative sources are used more.
2. Alternative energy sources are not necessary today.
3. Fossil fuel is considered clean energy.
4. Water, wind, the sun are common alternative sources of energy.
5. Clean energy is the energy that does not cause pollution.

FOSSIL FUELS

The sun’s energy is stored in coal, natural gas, water and wind. Coal, oil and natural gas are known as fossil fuels. Fossil fuels were formed over millions of years when the remains and fossils of prehistoric plants and animals sank to the bottom of swamps and oceans.

We use the energy in these fossils fuels to make electricity. We use electricity in many different ways. We light and heat our homes, schools and businesses using electricity, and to run computers, refrigerators, washing machines and air conditioners. Our cars and planes run on gasoline, which comes from oil. As of the year 2013, most of the energy we use comes from fossil fuels.
1. Where is the sun’s energy stored?

__________________________________________________________________________

2. What is the example of fossil fuels?

3. Where do we get most of electricity from?

IV.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 alternative sources of power. According to Professor Marvin Burnharm 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 is that we should use natural resources as economical as possible.

Statements

T/ F

1. Natural resources will run out.

2. The world’s energy resources are unlimited.

3. We know exactly how much fuel is left.

4. We should use fuel economically.

5. According to Professor Marvin Burnham, nuclear power will be used as a substitute for natural resources.

6. Many people disagree to use nuclear power as an alternative energy.

7. Radioactivity from nuclear power causes cancer and may have bad effect on the future generations.

8. Natural resources should be used as economical as possible.
