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
5. Do you think that saving energy is necessary ? Why ?
=> Yes, I think because nobody of us can live without energy
6. What should you do to save energy for your house or your school?
=> 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.
Environment is a set of natural factors that serve human life. These factors interact together to form an association that has a positive or negative impact on people's life.
People are facing many risks because of the imbalance of the environment. It causes serious harm to human health: It causes terrible diseases such as cancer, dermatitis, eye inflammation, diarrhea, epidemics that are difficult to control, ... Not only that, air pollution also indirectly causes water pollution, emissions such as carbon dioxide, sulfur dioxide will combine with water vapor to form dangerous acid rain, both polluting water sources, harming human health, and destroying construction works. Causing consequences such as forest fires, causing ecological imbalances, destroying the habitats of many wildlife species, making them close to the brink of extinction. The amount of smoke emitted from factories and factories is also one of the main reasons for destroying the ozone layer, causing ultraviolet rays to shine on the earth, seriously affecting human life.
Therefore, we have to actively plant trees to cause forests, consciously dispose of garbage at the right place. In industrialization activities, it is necessary to involve the state in strictly managing the standard waste treatment process, before discharging it into lakes, rivers and streams. Actively clean and clean the residence, keep the living environment fresh, clean and beautiful, actively propagate with everyone and every house about the harmful effects of environmental pollution, mobilize people to actively participate and have awareness of environmental protection. Please use energy saving, turn off lights when not needed.
Let's join hands to save energy, protect the environment - our invaluable resource.
Energy is very important to our life.Today I want to talk you about some easy ways to save energy.Firstly,we should save energy by turning off all the appliences such as: lights bulb,fans,.......Secondly,we should take shower instead of bath,use as enough water as need,.....Finally we should go to school by bike or on foot if the distance between our house is short,....We should save our energy to protect the natural resources of the earth

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.
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.
