1) Energy is very important in our daily life. We use energy for almost everything we do. However, energy is limited. We should do the following things to save energy. Firstly, we should use electricity more efficiently. Secondly, we had better reduce our electricity bills. Besides, it’s necessary to turn off the lights when leaving a room or before going to bed to save energy. Moreover, we ought to reduce the use of fossil fuels. In short, we should try our best to save energy for our future and our planet’s future.

2) Statistics of the energy industry over time show that energy consumption demand in any form such as primary energy, nuclear energy, or renewable energy is increasing. The primary energy growth rate is about 1.5%/year (fossil energy sources account for 90% of total primary energy consumption), and renewable energy increases about 15-16%/year...

With such an increase in demand, traditional energy sources will inevitably be exhausted. According to Assoc. Prof. Dr. Bui Huy Phung, Vietnam Energy Association, energy sources such as hydroelectric power have been exhausted, oil and gas are only used for about 50 years, and coal reserves are better with about 1000 billion tons. – can be used for more than 100 years. In general, they are finite.
Facing the above situation, the transformation of energy structure is necessary and strategic. Assoc. Prof. Dr. Bui Huy Phung commented: “With the relatively modest energy consumption, Vietnam has shown a lack of resources: hydropower has run out, storage hydropower has just started, but must have "free resources" to accumulate. ability to be; There is not much coal, oil, and gas. In recent years, tens of millions of tons of coal and oil have to be imported, so the requirement to supplement and change the structure of energy sources is necessary and objective.

And according to him, renewable energy and nuclear have endless potential. However, he also said that which energy source to use depends on the national financial situation and the strength of the energy source.

Provided that Vietnam's energy source, like many other countries in the world, renewable energy, especially solar power and wind power, is assessed to have abundant potential.

3) For a student going to university to study, we are all familiar with the image of the bus. This is a large form of transportation. The bus can carry many people at the same time. To be able to travel by bus you need to go to the bus stop. Here people will wait for the bus to have the right destination for their needs. Buses have doors to get on and off. When traveling by bus during rush hours, you will sometimes have to stand. When standing, there will be a handle at the top for you to hold as support. The bus has lots of windows. On rainy days, riding a bus, listening to music you love, and watching the raindrops through the glass window is wonderful. I often take the bus to go to school, to work, and hang out. I can go anywhere by bus. I like the convenience of it.

Atomic energy, solar energy, and energy from wind and bio fuels are just a few of the promising alternatives for a cleaner and greener future. Other relatively new sources of energy such as fuel cells, geothermal energy, and ocean energy are also being explored.

3)I think subways should be used because they can carry more passengers, are faster than buses, and are more environmentally friendly because they use electric power.
