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.

Today, we can easily grasp a lot of information from various sources on the internet and especially through social networks with fast transmission speeds. Social networking has become more popular and accessible to everyone especially for young people. The purpose of social networking is to create an Internet-based system that allows users to communicate and share information effectively, beyond the limits of geography and network benefits time.But society gives us a lot of positive impact and if we know how to use them in a reasonable manner.

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.

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.
