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.

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.

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
- The use of energy sources may be leads to air pollution, climate change, water pollution, thermal pollution,... But in my city, people use energy properly everyday so we haven't seen any problems yet.
* ở nơi mình sống là thế, nên bạn thay sao cho phù hợp với nơi bạn sống nhé!
- I think we can save energy by using fewer household electrical appliances, use energy economically, turn off all lights, fans, air conditioner when not use, etc.
Question 1:
In my city, there are several potential problems associated with the use of energy sources:
1. Pollution: The burning of fossil fuels for energy production can release harmful pollutants into the air, leading to air pollution and contributing to climate change. This pollution can have adverse effects on public health and the environment.
2. Resource Depletion: Dependence on finite resources like coal, oil, and natural gas for energy generation can lead to resource depletion over time. As these resources become scarcer, it may lead to price increases and economic instability.
3. Environmental Degradation: Extracting and processing fossil fuels can cause environmental degradation, such as deforestation, habitat destruction, and water pollution. This can harm ecosystems and biodiversity, disrupting natural balances.
4. Greenhouse Gas Emissions: The combustion of fossil fuels releases greenhouse gases like carbon dioxide into the atmosphere, contributing to global warming and climate change. This can lead to more frequent and severe weather events, rising sea levels, and disruptions to ecosystems and human societies.
5. Energy Inefficiency: Some energy sources, such as older power plants or outdated infrastructure, may be inefficient in converting fuel into usable energy. This inefficiency leads to wastage of resources and higher energy costs for consumers.
6. Dependency on Imports: If a city relies heavily on imported energy sources, such as oil or natural gas, it becomes vulnerable to price fluctuations and geopolitical tensions in supplier countries. Diversifying energy sources and investing in local renewable energy can help reduce this dependency.
Addressing these problems requires a shift towards cleaner and more sustainable energy sources, such as renewable energy (solar, wind, hydroelectric) and increased energy efficiency measures. Transitioning to these alternatives can mitigate environmental impacts, enhance energy security, and promote economic development.
Question 2:
In my city, there are several ways to save energy sources:
1. Saving electricity: Turn off lights, fans, and electronic devices when not in use to save electricity. Use energy-efficient LED bulbs instead of traditional incandescent bulbs.
2. Using renewable energy: Encourage the use of renewable energy sources such as solar panels and wind turbines to generate electricity. These sources are sustainable and do not deplete natural resources.
3. Using public transportation: Use public transportation such as buses or trains instead of personal vehicles to reduce fuel consumption and air pollution. Walking or biking for short distances is also a good way to save energy.
4. Conserving water: Saving water also helps save energy because energy is used to pump, treat, and heat water. Take shorter showers, fix leaks, and use water-saving devices to conserve water.
5. Insulating homes: Properly insulating homes can reduce the need for heating and cooling, saving energy. Install insulation in walls, ceilings, and floors, and use energy-efficient windows and doors to keep homes comfortable.
6. Planting trees: Trees provide shade and reduce the need for air conditioning in buildings, saving energy. Planting trees in cities helps cool the environment and improve air quality.
By implementing these measures, we can effectively save energy sources and create a more sustainable city for the future.
