Writing Feedback / Renewable sources of energy (sun, water, wind) will soon replace fossil fuels [4]

What score do you think I will get(TOEFL) writing? Also I want your opinion about my writing. Thanks^^

These days, one of the most important problems throughout the global is an environment-related problem, due to fossil fuels polluting air, water and for causing global warming. These lead to many countries like America, trying to develop sustainable energy resources. But, would these fossil fuels can be replaced by energy which can be used again? In my view, I hold with the notion that renewable sources would replace the energy used these days.

First, renewable energy like water, wind, and solar energy is nature friendly. So, replacing fossil fuels with these energy can solve the problem, global warming which occurred by charcoal, petroleum, and gas destroying the ozone layer. To illustrate, when we ride buses, there are many buses using renewable sources. And the numbers of these buses are increasing as the time passes. Also, according to the research done by three colleges in America says buses and other transportation are using these energy sources starting from early 2000, and the number is growing, so over 10 millions buses and other transportation is using these sources these days.

Second, literally, renewable energy could be used again, unlike nonrenewable a resource which is limited. So, sooner or later, we would be run out of nonrenewable resources but, we would be in need of more energy than before. To give you an example like those times Korea undergone a crisis about having a shortage of gas. People desperately needed it to do all kinds of things. When we used of all fossil fuels, this kinds of incidents would happen every day. But, when we look at renewable energy, we can get it from nature whenever we want and also, it is not limited. As a way for getting this energy, it will cost a lot of money, but soon, we will earn more energy than its costs. For instance, a town in Germany has a very clean air due to almost all the people in that town using solar energy they got from sun.

I have come to the conclusion that soon, nonrenewable resources would be replaced by renewable energy for two reasons. First, they do not pollute the air and are no harm to nature. Second, consecutive resources can be produced again and again. I hope renewable resources could be more developed so it would not destroy the nature.

Writing Feedback / Letters, email, or telephone communication? Yes - it's more comfortable and can save time and money [5]

Before technology was developed, we had only face to face communication. However thanks to the development of technology, various ways of communication was invented. There are such as letters, email, or telephone calls. There are many debates about which way of communication is better. Both ways have many advantages and disadvantages. But, I go along with the idea that using other communication instead of face to face communication is better. I have three reasons to support my opinion.

First, I think it is because you can have more comfortable times talking not in face to face. The scientific research has shown that many people have a tendency to express their feeling more comfortably when they do not see each other's face. As for me, I feel the same way, especially when we are talking about embarrassing moments or apologizing for what I have done wrong. And that's the reason why we give letters or cards to each other. We can express our feeling more exuberantly.

Second, communicating with devices can save time and money. Because you do not have to meet other to have a talk to others in person, you do not have to devote your own time and money trying to meet him/her and to go to the meeting place. However in contrast, having a communication in person requires us money and time. So, using that time to do other thing else could be more precious to us.

Finally, you can record the conversation you were having with other. For example, when we give other a card or a letter, we can save it and read it again when we want to. Also this works on telephone, emails and other communication as well. Also, some letters in the old days are important sources for the historians. It is very important because they could learn mostly everyday life reading the letters. That would have been definite benefit for the historians.

I have come to the conclusion that other communication than face to face communication is better because it is more comfortable, can save time and money, and because we can record us communicating.
