1.Solar energy comes directly from the sun and this renewable energy source is sustainable.
2.This type of energy is environmentally friendly and does not cause pollution.
3.Solar energy is available everywhere and is very quiet because solar energy/its devices do not have any moving parts.
4.Solar panels are expensive as they use rare and special materials, and the technology used to store solar energy is costly.
5.Solar energy is not always available since access to sunlight is limited at certain times.
6.Although it is greener than fossil fuels, the production of solar panels may emit some greenhouse gases.

Nowadays, it has become necessary to use green technology with green renewable energy sources. Among all green energy sources, solar energy is the most important renewable energy source, which has both advantages and disadvantages.
First of all, solar energy comes directly from the sun and this abundant renewable energy source is sustainable. In general, this type of energy is environmentally friendly and does not cause pollution. Another advantage is that solar energy is available everywhere in the world, not only in hot and sunny countries near the Equator. Furthermore, it is very quiet because solar energy devices do not have any moving parts.
However, solar energy is not cheap. Solar panels are expensive to produce as they use rare and special materials. In addition, the technology used to store solar energy is costly. A further disadvantage is that solar energy is not always available since access to sunlight is limited at certain times. Furthermore, although it is greener than fossil fuels, the production of solar panels may emit some greenhouse gases.
In short, there is no energy source that is completely risk-free. However, the pros of solar energy as a renewable energy source outweigh the cons. I hope that further development of green technology will soon eliminate the disadvantages.
