Advantages of Solar Power?
- Solar energy is a clean and renewable energy source.
- Once a solar panel is installed, solar energy can be produced free of charge.
- Solar energy will last forever whereas it is estimated that the world’s oil reserves will last for 30 to 40 years.
- Solar energy causes no pollution.
- Solar cells make absolutely no noise at all. On the other hand, the giant machines utilized for pumping oil are extremely noisy and therefore very impractical.
- Very little maintenance is needed to keep solar cells running. There are no moving parts in a solar cell which makes it impossible to really damage them.
- In the long term, there can be a high return on investment due to the amount of free energy a solar panel can produce, it is estimated that the average household will see 50% of their energy coming in from solar panels.
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.

2,Solar energy is convenient and abundant but sometimes they are not available.
3,In Vietnam, people use both non-renewable energy sources like coal, oil, natural gas and renewable ones like hydro and solar power. Vietnam still relies mostly on non-renewable energy resources. However, hydro power is increasingly used. In some areas, people also use solar power to heat water and biogas is used for cooking.

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.

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.

Keeping the school campus neat and clean is very important for all the students because a school is a place to study and learn. If the physical environment is not an attractive one, then studying and learning become less pleasant and the concentration of the students will be hampered. To keep the school campus neat and clean the students have to do some certain works. Firstly, in every class the students can make a class forum or group and the leader of the forum can divide the works. There are different works in the school campus. According to the instruction of the leader the students will continue the work. Some students of a forum can arrange of garbage and rubbish in waste disposal containers, take care of the gardens and trees. Similarly, another group can keep the plants well-trimmed, mow the lawn, and trim the grass around the borders. Other group can rake the fallen leaves, keep the statues well-polished, mop and vacuum the floors and carpets inside. Some can clean the walls, windows and other surfaces. To keep the campus always neat and clean the students can make some rules permanently both inside and outside of the classroom. Firstly, students should not spit in the class, drop litter in the class. Secondly, they have to use the bin for trash and keep the desks and chairs in place. At the time of performing the works they can get any help from their class teacher and other teachers. In this process the students can keep their school campus neat and clean.

Nowadays, the demand for electricity for every human being is very important. Electricity at the beginning of a new era was high-tech products: light bulbs, telephones, computers, etc. However, people have been using electricity wastefully, indiscriminately, polluting the environment.To prevent wasteful using electricity, people have developed a new type of electricity, which is solar power.In fact, there are a lot of ways to use solar energy in our daily lives, as there are also a lot of solar-powered consumer products available for easy use of solar energy and a greener life. These include portable solar panels, solar chargers and solar lights. In addition, new solar innovations are being introduced to the market every day and widely applied. Therefore, among the various advantages of solar energy, the main advantage is that it can be accessed and installed by almost everyone.The use of solar power may not completely replace the grid power, but it will reduce the monthly electricity bill of the family.However, in order to use solar technology, it is necessary to ensure: the direction of receiving the sun, the direction of wind, the width of space. Weather conditions are also important for solar installations, in some places the sun does not rise in the winter, thus affecting demand for electricity.If you want to use solar energy, you will need to expert for their advice!
