Wind Turbine characteristics



The diagrams illustrate how a wind turbine is designed for generating electricity and several options where a wind turbine can be placed.

To begin with, a wind turbine consists of the steel tower, blades, wind sensor, generator, controlling house and computer. Steel tower has certain high, approximately twice as high as its blade. In addition, there are three blades that are made of fiberglass or wood. These blades are facing the wind direction, and there is also a wind sensor that has functioned as to control blade speed and blade direction. When the wind is blowing the blades, it will turn the blade and the generator will produce electricity with maximum output 1.5 megawatts. Meanwhile, computer in a controlling house directly connect with wind sensor. This computer is functioned to manage blade direction and angle.

Furthermore, there are three alternative locations for placing a wind turbine. The first option is placing in a top of mountain. This site is the best option to build a wind turbine because the wind will flow in the maximum strengths. Second alternative place is putting a wind turbine in off shore, and in this site will give an advantage that the landscape will be not destroyed by the effect of wind turbine. While the last choice to place a wind turbine is in the near of human house, it means that it is not the best place because the output of turbine is only generating maximum 100 kilowatts.

In general, a design of wind turbine has standard design and has main features that have important role. There are also many options to placing a wind turbine in certain site and each site has each advantage.

Aziz, I am not sure why you attached the black and white copy of the illustration. The one with the keywords to be used in the essay. Were you supposed to use the words? If you were, I certainly did not find any references to it in the essay. Please clarify why you posted the other diagram as well.

Your essay did not really deliver on all points of the prompt requirement. You were supposed to make comparisons where relevant within your summary presentation. This should have been done when you discussed the height and positioning of the wind turbine in comparison to the air and power generated at every level. Since you did not do that in this presentation, you would have lost a number of important points in the final scoring.

Try to work on improving your summary and conclusion paragraphs. These are extremely short and do not really deliver on the required information for these paragraphs. Both are supposed to offer a summary overview , in the case of the opening statement, and a wrap up for the provided discussion, in the concluding paragraph. Neither of which are seen in your essay. So I think the best score that you can get for this essay would be a 4 overall. That is due to the missing comparisons and improper length of the opening summary and concluding statement.

I understand that this is your very first posting here at EF. So I will not feel so bad if I were you. I have given you comments and advice that you can apply to your next and other succeeding task 1 essays. If you follow my advice, you should show improvement over the next few essays. I will make sure that you improve. I'll be here to help you every step of the way. Don't worry or feel frustrated. This is just your first try, there is plenty of room for improvement on your end.

@Holt. thank for you comment and suggestion. The diagram actually just one. I forget to delete the first one (black illustration). both of diagrams are similar.
