A gas that is made up mostly of methane and found near other fossil fuels, like coal. Methanogenic processes occurring in landfills and marshes also produce natural gas. Like petroleum, natural gas must first be processed before we can use it as a fuel. It is important to remove most of the other components of natural gas until it is almost purely methane. When combusted, natural gas produces only about half the greenhouse gas emissions as coal does, making it a popular fossil fuel in our increasingly carbon-conscious society.

mình không chắc chắn lắm đâu vì phần sắp xếp câu mình còn rất yếu. :>

1. There are 10 types of energysources. They are: solar energy, wind energy, geothermal energy, hydrogen energy, tidal energy, wave energy, hydroelectric energy, biomass energy, nuclear power, fossil fuels ( coal, oil and natural gas).

2. I can use less electric, use more natural energy,...

3. Renewable energy means the energy never exhausted such as solar energy, wind energy,...

4. I think my carbon footprint is medium.

5. Yes, I have.

Put the sentences to make a logical dialogue

A. How can we do that, Dad?

B. Sure, Dad.

C. Anh we will use renewable energy sources like solar energy.

D. I will ride a bike to school tomorrow. What else, Dad?

E. We can travel by public transport or bicycles.

F. What are non-renewable sources of energy, Dad?

G. Is it a better source of energy?

H. Ph, so they will run out.

I. Yes, it is clean and plentiful

J. Yes. That's why we have to save the energy

L. Well, those sources of energy are limited and can't be replaced after use

M. You should turn off the TV or computer when you don't use them.

=> F -> L -> H -> J -> A -> M -> B -> E -> D -> C -> G -> I

Có bị thiếu cái nào ko bn?

As you know, sources of energy like solar energy, wind energy,.. are very important. People use them for many things:cooking, heating,ect...But, almost the sources of energy have the disadvantages and advantages. There are two kinds of energy:non-renewable and renewable energy. Non-renewable is very popular in many countries. They are abundant, available and easy to use. However, they won't last forever and they're harmful for the environment. And, people will use renewable energy to solve the problems of non-renewable energy. Renewable sources of energy are forever and they're clean and safe, too. Nevertheless, they have some problems, too. For example, nuclear is clean but it's dangerous to use. Wind power has many advantages but it isn't available,... On the other hand, there are some sources of energy don't have some serious problems like solar energy. It's the reason why people use solar energy in the future. So, what should we do to save energy? We should use them properly and use them less. We should use less cars or motorbike, too. It also have the enviroment. Energy is very important, we should protect them for our life in the future.

Sai đề rồi nha bạn Carbon không có nghĩa còn footprint là dấu chân

carbon là các-bon mà bạn

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
