UNIT 10: SOURCES OF ENERGY

READING

I.Read the following passage then decide if the statements are true or false.

Fossil fuels (oil, coal, and natural gas) are very important tin the production of energy, although they produce a lot of carbon dioxide that harms the environment. However, they are rapidly running out because they are non-renewable energy sources.

People are looking for cleaner and safer alternative sources of energy. For example, solar energy is unlimited and is easy to get. In some countries, people put solar panels on the roofs of houses and buildings for heating and hot water. In addition, hydro power is cheap and plentiful. They are increasingly used to generate electricity. Although nuclear power is also clean and abundant, it is dangerous and may cause serious accidents.

Viet Nam still relies heavily on fossil fuels for energy at the moment. Before other renewable sources of energy become popular in Viet Nam, we need to limit energy consumption to protect our environment.

T F
1. Fossil fuels are running out.
2. People put solar panels inside their houses for heating and hot water.
3. Both hydro power and nuclear power are abundant.
4. Nuclear power is dangerous and may cause accidents.
5. Viet Nam is using more renewable resources than fossil fuels.

II.Read the passage and circle A, B or C to complete the sentences.

Nga’s family wants to reduce their energy consumption. Nga and her brother will go to school by bicycle, while her mother will take the bus to work. Tomorrow, her mother will buy some low energy light bulbs to use in all rooms. Besides, at 5 o’clock tomorrow afternoon, dad will be putting solar panels on the roof of their house. From next week, all the water in Nga’s house will be heated by solar energy. Nga also tells her brother to turn off the lights when he gets out of the room.

Nga and her family feel happy that they have small carbon footprints because they are using less energy that produces carbon dioxide.

A.by bus B. by bike C. on foot

2.At 5 o’clock tomorrow afternoon, dad…………………solar panels on the roof of their house.

A.will be put B. puts C. will be putting

And teachers don’t  want to work in communities where there are no lights, little equipment, no TVs, computers or life after dark.

IV.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 money as well as conserve the Earth’s resources.

T F
  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.
