Topic: SOURCES OF ENERGY
1. Tell me about some renewable sources of energy and nonrenewable sources of energy.
=> Renewable sources of energy : wind,hydro,solar ,...
Non-renewable sources of energy: coal,natural,oil ,.....
2. What types of energy does VN use most?
=> Viet Nam uses non-renewable most
3. What types of energy do you think VN will use more in future ?
=> I think Viet Nam will use renewable sources of energy more in the future
4. Why is the wind/sun called alternative sources of energy?
=> Because it's can replace easily

=> You should: use electricity more efficiently
turn of the lights when we aren't using them
use low energy light bulbs
use public transport
rewable:wind,solar enery,hydro,nuclear,biogas...
non rewable:coal,oil,natural gas...i think people will use it more in the future
- What you should do to save energy
With fast growth of civilization there is also an ever mounting need for energy. Energy may be in the form of fuels or electricity. Petrol is a liquid fuel which is used widely nowadays. But this kind of fuels is likely to be exhausted at the rate man is using it recently.
To meet the challenge, various methods have been suggested. One is to minimize the man’s demand in using the energy. Non-essential consumption should be minimized. During certain days of the year, people all over the world turn off the electricity for 1 hour to save the energy. Modern gadgets consuming energy should only be used when they are absolutely necessary.
Energy conservation is possible through modernization of plant and equipment. People should replace the obsolete equipment by the modern ones.
Energy can be saved on transport by the following methods. People should commute by the rail rather than by cars and vans. The transport must be improved with a view to sparing the energy. Cities must be planned in such a way that the commuting distance from this place to others is minimized.
In industry, many things could be done to reduce waste of energy or to economize energy. The machine maintenance needs to be tightened; heater must be utilized properly. When systems are streamlined, economy in fuel is obvious. Instead of using materials requiring higher energy, those which require lower energy should be used.
We hope man with his ever rising urge for existence will cope up with this urgent problem and find alternatives.
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.
1. How many types of energy sources 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 can not 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 energy and we use them instead of non-renewable sources.
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 Vietnam will use the wind and the sun as alternative sources of energy in the future.
My house primarily relies on electricity and gas for energy. Electricity powers most appliances and lighting, offering convenience but contributing to high consumption. Gas fuels the heating system, providing warmth efficiently but releasing emissions. To save energy, I've adopted simple habits: switching to LED bulbs, unplugging devices not in use, and using energy-efficient appliances. I've also improved insulation and sealed drafts to minimize heat loss. Moreover, I'm conscious of water usage, opting for efficient fixtures and practicing conservation. These steps not only save energy but also reduce environmental impact, aligning with my commitment to sustainability.
