what are advantages of solar energy?
what are disadvantages of natural gas?
What is the main source of energy at present?
what are some alternative sources of energy?
what are their advantages and disadvantages?
The main source of energy at present is fossil fuel.
Some alternative sources of energy are wave energy, solar energy, biofuels, natural gas, geothermal power, wind energy, biomass energy, tidal energy, hydrogen gas, etc.
Their advantages are that they are renewable and is most likely to never run out. Also, they are easier to find than fossil fuels. They produce little or no waste that is harmful to the environment like carbon dioxide or methane so they are more environmentally friendly. Their disadvantages are that they don't produce as much energy/electricity as fossil fuels. Another disadvantage is that they rely on their surrounding. For example, wind energy needs to be generated at a windy location and needs wind turbines that take up a lot of space or solar energy needs to be generated at a sunny area and needs lots of solar panels.
Talk about the advantages and disadvantages of sources of energy you know.
- What kind of the sources of energy? ( renewable or non - renewable)
- What are the advantages/ disadvantages of the sources of energy?
- What do you think people will use it more in the future?
rewable:wind,solar enery,hydro,nuclear,biogas...
non rewable:coal,oil,natural gas...i think people will use it more in the future
Give examples about renewable energy? What are the advantages and disadvantages of using it?
Renewable energy comes from a source that will not deplete. Two common examples of this type of energy are solar power and wind power. Geothermal power, hydropower, biomass, and tidal power are additional forms of renewable energy that produce power for our planet right now.
The primary advantage of renewable energy is that fewer potentially harmful emissions are released into the atmosphere. Although fossil fuels are used to create the products that allow for this power to be produced, most forms of renewable energy can become carbon neutral in 5 years or less.
The disadvantage of renewable energy is that it can be costly. Although wind power and solar power have become cost-competitive with coal-fired power and nuclear power in some communities, some forms are not cost-competitive globally yet when the cost per kilowatt hour is compared. In 2015, the lifetime cost per kilowatt hour of conventional coal was 9.5 cents, while the cost of offshore wind was 15.8 cents.
There are additional advantages and disadvantages of renewable energy to consider as well.Write a paragraph of 80-100 words about “ How to save energy in your house”
1. What sources of energy does your house use?
2. What are their advantages and disadvantages?
3. What do you do to save energy and protect the environment?
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.
Write an essay about advantages and disadvantages of a typer of energy ( viết 1 bài luận về những lợi thế và bất lợi của 1 loại năng lượng ) .
BODY:
- first of all , using solar energy brings us many advantages
- there are many advantages of solar energy . first (1) , second(2) , more over (3) , .....
- using solar energy is very convenient and useful . however , it has certain disadvantages
Disadvantages of Solar Power?Solar panels can be expensive to install resulting in a time-lag of many years for savings on energy bills to match initial investments.Electricity generation depends entirely on a countries exposure to sunlight; this could be limited by a countries climate.Solar power stations do not match the power output of similar sized conventional power stations; they can also be very expensive to build.Solar power is used to charge batteries so that solar powered devices can be used at night. The batteries can often be large and heavy, taking up space and needing to be replaced from time to time.
Write a paragraph about sources of energy.
1. Tell me some sources of energy you know.

As you know, sources of energy like solar energy, wind energy,.. are very important. People use them for many things:cooking, heating,ect...But, almost the sources of energy have the disadvantages and advantages. There are two kinds of energy:non-renewable and renewable energy. Non-renewable is very popular in many countries. They are abundant, available and easy to use. However, they won't last forever and they're harmful for the environment. And, people will use renewable energy to solve the problems of non-renewable energy. Renewable sources of energy are forever and they're clean and safe, too. Nevertheless, they have some problems, too. For example, nuclear is clean but it's dangerous to use. Wind power has many advantages but it isn't available,... On the other hand, there are some sources of energy don't have some serious problems like solar energy. It's the reason why people use solar energy in the future. So, what should we do to save energy? We should use them properly and use them less. We should use less cars or motorbike, too. It also have the enviroment. Energy is very important, we should protect them for our life in the future.

- talk about the ways of reducing pollution at your school
Environment is an essential part of our life. A clean environment is necessary for a peaceful and healthy life. An environment is the natural surroundings which helps human beings, animals and other living things to grow and develop naturally. But nowadays, our environment is disturbing in many different ways. Any type of disturbance in the nature’s balance affects the environment totally. It does not only ruin human lives but also affects on all living beings. We can save our environment with the little step taken by everyone on the earth. We should reduce the amount of waste, throwing wastes properly to its place only…and many other simple ways. It is very important to save environment for human existence. When we protect the environment, we are protecting ourselves and our future as well.
- What are the advantages or disadvantages of using mobile phone
Smart phone has played a very important role in our lives. It is an useful entertaining instrument. We can download a lot of games or books, music, movies and they are free. After a stressful working day, this will be a good way to relieve stress and get back energy. In addition, the phone is also considered one of the modern educational methods. Only with the phone connected to the Internet, we can access and surf the web to enlarge knowledge. On the Internet there are a lot of different knowledge from literature, theology, history, physics to astronomy and politics. Moreover, there are also a number of other helpful news channels, which helps us broaden our knowledge of cooking, fashion, behavior in communication, ... Last but not least, because of the compact , being easy to carry so the phone is loved by almost people. We can take it to anywhere and use it any time. In short, the phone offers a lot of great benefits. Each of us should use it reasonably and efficiently.
talk about the ways of reducing pollution at your school
Our school looks so dirty these days. And it's time to save our school before it's too late. There are many ways of protecting the environment at our school.
Firstly, we should reduce and reuse bottles, cans and plastic bags because they are hard to dissolve. If we do so we can save energy and even make more money from selling those things.
Secondly, we shouldn't throw trash on the school ground because it doesn't only cause pollution but also do harm to our health and make us get sick.
Thirdly, we should make sure our lunch table is clean before we leave. Don't leave milk cartons, napkins or pieces of food on our table. Push in our chairs as we leave the table and remember to check the floor to make sure we didn't drop anything.
Finally, we should go to school by bike, on foot , or public transport to reduce exhaust fumes and save energy.
In conclusion, reducing pollution at our school means that we are improving the quality of our study time.
