In H’s article entitled “Sun Power: Solar Thermal Hot Water Systems Save Energy and Money”, he points out that solar thermal hot water systems are very good devices because they save both energy and money. First of all, he states that solar thermal systems are gradually becoming popular in a lot of places in the United States because of their good performance. He also states that many solar thermal systems are used in public, municipal, or government buildings because these spaces consume large quantities of water. Next, he claims that solar thermal systems are very useful because they generate electricity, and reduce homeowner’s expenses. Third, he points out some disadvantages of solar thermal systems. He also states these devices are difficult to sell because the cost is quite expensive and other replacements might be required to maintain these devices. In conclusion, the author suggests that everything that is related to solar is developing day by day; therefore, solar thermal systems will be used in coming years.

It is clear that solar thermal systems are really useful because of their energy efficiency. Then, they can save not only energy but also money. The author has a good point. Solar thermal systems have many advantages. Therefore, the governments of each country should recommend that people use more solar energy from solar thermal systems than any other energy for protecting environment, reducing energy consumption, and saving money.

First, using solar thermal systems helps environment of the Earth because they never produce harmful substances such as carbon dioxide. In “Environment: Problems and Solutions”, Miller (1994) said “Solar cells produce no heat-trapping carbon dioxide during use. Air and water pollution during operation is extremely low. Air pollution from their manufacture is low, and land disturbance is very low for roof-mounted systems” (p. 88). Therefore, the possibility that they destroy environment of the Earth is quite low. If people try to use solar energy instead of fossil fuels, the Earth will escape from some environmental problems such as air pollution or acid rain.

Second, solar thermal systems can reduce the consumption of the use of fossil fuels. Solar thermal systems use sunlight to heat water in rooftop collector and store in tanks for use throughout the home. Since sunlight is unlimited, people can use solar energy forever unless the sun dies or the device goes out of order. However, if they continue to use fossil fuels such as oil, these energy resources will decrease and finally run out as we use them. Therefore, solar thermal systems are very useful because the solar energy is never run out.

Finally, if people use fossil fuels, they have to use a large amount of cost to mine this energy and convert them into other energy. On the other hand, if people start to use solar thermal systems, they can save their money because they can get energy from the sun for free. As a result, even though they have to pay money for initial costs, they can get and use energy for a long time for free if they buy these devices once. Therefore, solar thermal systems are very economical devices.
In conclusion, using solar thermal systems has a lot of benefits such as protecting environment of the Earth, decreasing energy consumption, and saving money. Since it has useful function, people should try to use solar thermal systems more aggressively. In fact, solar thermal systems are becoming popular among a lot of countries to save other resources. Since natural resources should be preserved for people in the future, solar power is necessary so that they could live on the Earth forever.
