Focus Solution "Solar Energy" and My Voice Thread

For a couple of decades, we have used the sun for drying clothes and food, while it recently has used for generating electricity that comes from the sun-light which called solar energy. In fact, solar energy is enough to cover our demands for many years, if we use it properly. Now, I’m going to write about the advantages and disadvantages of solar energy.

There are several distinct advantages of solar energy. One of these advantages is that solar energy can be used widely in sunny countries like, UAE. Also, solar energy is free and doesn’t produce pollution, so it is environmentally friendly. So, we can reduce pollution by using it. Another benefit is that it is economical, because it can only operate with a little maintenance after the initial setup.

Although there are several advantages, there are also some important disadvantages. One drawback is that solar energy does not work at night, but we can use the power save from day light. Also, it needs large areas to get enough energy. Another disadvantage is that it is very expensive to build solar power stations especially polysilicon solar cells that need a large initial capital investment.

Overall, in my opinion solar energy is one of these energy alternatives that we need used it with little pollution. It is used for many applications these days like heating water and building, cooking and generating electricity.
