Written by my dd this evening for homework:
"Wind Power
Some people say that wind power is good, because it doesn't produce pollution like other means of producing electricity. However other people argue that the building materials needed to produce wind turbines (such as metal) are non-renewable. People who live in close proximity to wind turbines say that they are clean and efficient. But other people discuss the fact that they are noisy and only produce 20% of the energy required."
Very eloquently put!
