Mở bài: Everyone in the world uses energy. Fossil energy is gradually depleted and also causes environmental destruction. Therefore, people are going to use clean energy to protect the environment and maintain use. My favorite energy source is solar energy.

Kết bài. Thus, solar energy is really useful, it has more advantages than disadvantages and can be used for a long time.

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.
