Dear guests, I’d like to talk to you today about renewable and non-renewable energy. Fossil fuels are non-renewable energy sources. They include oil, coal, and natural gas. They can be used to create energy, generate electricity, or drive big machinery. Unfortunately, they are harmful to the environment. Viet Nam still relies mostly on non-renewable energy sources, however, hydro power is increasingly used here too.

Hydro and nuclear power can generate a great deal of energy. They are renewable and plentiful. However, hydro power is limited because dams cannot be built in certain areas. Nuclear power can provide enough electricity for the world’s needs, but it is dangerous. The sun and the wind are other alternative sources of energy. The wind turns turbines to

make electricity. Solar power can be converted into electricity. It can be used to heat or cool our houses. Although there are some disadvantages, these alternative energy sources can offer abundant amounts of clean, safe electricity. They will be valued more and more in the future in Viet Nam.

1.How many types of energy sources are mentioned in the text? What are they?

2.What are the disadvantages of hydro and nuclear power?

3.Why do you think the wind and the sun are called alternative sources of energy?

4.What types of energy does Viet Nam use most?

5.What does the professor think Viet Nam will use more in the future?

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

SOLAR ENERGY

Sunlight carries huge amounts of energy. You can feel the Sun’s energy when sunlight warms your skin on a summer day. To capture the Sun’s energy, scientists have developed solar cells, called photovoltaic cells. These cells convert sunlight into electricity. When sunlight hits a solar cell, some of the light energy is absorbed. This light energy causes the particles in the solar cell to move faster, and the movement of these particles creates electricity.

In some places, large panels of solar cells harvest sunshine to make electricity for homes and businesses. Solar cells have been placed on cars and appliances, too. Since the Sun sends abundant free energy streaming toward Earth 24 hours a day, people in many parts of the world, not just the sunniest places, have fixed solar cells and solar panels on the roofs of their houses or businesses to lower their energy costs. Experts say that the huge installation of solar panels in sunny regions could generate enough electricity to supply an entire country. Capturing this energy can help overcome our diminishing energy supply. New ways to capture this energy are being developed an the time to maximize efficiency.

1. What is the source of solar energy?

a. sunlight b. photovoltaic cells c. solar panels d. electricity

2. Solar cells are used __________

a. to collect energy from the sun b. to provide sunlight to houses

c. to convert sunlight into electricity d. both a and c are correct

3. Which of the following statements is true?

a. Solar cells absorb all of the light energy from the sun.

b. The light energy causes the particles to move faster to make electricity.

c. Solar energy can be used to power homes and businesses only.

d. Large solar panels have been placed on cars and appliances.

4. As used in line 9, ‘abundant’ most nearly means .

a. Unlimited b. dangerous c. plentiful d. clean

5. Where have people fixed solar panels?

a. In the sunniest places b. Anywhere outside their houses

c. Inside their houses d. On the roofs of their houses

6. As used in line 14, ‘diminishing’ most nearly means .

a. Decreasing b. increasing c. unending d. restoring

7. According to the passage, all of the following statements are true EXCEPT

a. the Sun produces a large amount of energy.

b. solar energy could provide enough electricity for the whole world

c. scientists are constantly developing new ways to capture the Sun’s energy

d. people use solar energy to reduce their energy costs.

Energy is fundamental to human beings. Many poor people in developing countries do not have modern sources of energy like electricity or natural gas, with which their life can be improved.

People who live in mountainous areas have to gather wood for fuel. This takes a lot of time. For many people living in rural areas, biogas is the largest energy resource available. The main use of biogas is for cooking and heating, but it can also provide energy for public transport. As biogas is smoke-free, it helps solve the problem of indoor air pollution. Moreover, it’s made from plant waste and animal manure. They cost almost nothing.

The tendency to use renewable energy sources in developing countries is on the increase as non-renewable ones are running outIn the future, the wind and the sun will be used as the most important environmentally friendly energy sources.

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 harnessed 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 which statements are True (T) or False (F).
In Western countries, electricity, gas, and water are not luxuries but necessities. Companies now realize that consumers want products that will not only work effectively, but also save money.
For most North American households, lighting accounts for 10 percent to 15 percent of the electricity bill. However, this amount can be reduced by replacing an ordinary 100-watt light bulb with an energy-saving bulb. These bulbs use a quarter of the electricity of standard bulbs and last eight times longer. Therefore, consumers can save about US$7 to US$21 per bulb. In Europe, there is a labeling scheme for refrigerators, freezers, washing machines and tumble dryers. The label tells the consumers how much energy efficiency each model has, compared with other appliances in the same category. Ultimately, these innovations will save smoney as well as conserve the Earth's resources.

1. In Western countries, energy is cheap.
2. Consumers can save money by using energy-saving bulbs.
3. Labeling scheme is a good innovation which helps the European to save money and natural resources.
4. Ordinary 100-watt light bulbs use a quarter of the electricity of standard bulbs.
5. North American and European countries are interested in saving money and natural resources.
