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.

           In areas where water pollution is a problem, it is important to learn about the area and to conduct the renovation and use of the technologies or to hire foreign environmental specialists who have advanced technologies to change the water source. infected in the optimal time as possible.
           The media must also include environmental information as well as solutions on how to communicate with people in the environment, especially the water environment, such as information and communication. Everybody changes their minds to keep their sanitation in common with the environment as well as the water environment in Vietnam.
           On the limitation of these solutions, it is well known that it would require a lot of money to renovate or hire foreign experts, when it comes to the causes of water pollution in Vietnam. The solution is to try to change the environment of clean water, but if our human consciousness is that, one day we will also meet the scene of such black rivers.
           Therefore, let us protect our environment and our children in the future so that we can live in a clean environment, help us improve our health and ecosystems. in water environment.
