An alternative energy resource is wind power. This is not a new discovery but overtime it took a fresh and better tactic. History will reveal that hundreds of years ago, windmills were already use in Europe in wind farms with wind turbines in order to gain as much as wind energy as possible. This is an effective method in producing the maximum wind energy; however, there are pros and cons that one has to be aware with in this kind of alternative source of energy. IntroductionMissouri produces wind energy coming from more than 2,500 square miles land that the state use as 63% portion of electricity. Windmills are producer of clean energy; however worn-out windmills produce otherwise. One hazardous element of wind turbines is carbon fiber composite. When wind turbine is worn-out, it has to be burned and trashed out, a process that is perilous to the atmosphere. This wind turbine replacement is necessary. One material of wind turbine is thermoset plastic; this usually creates the wind turbines’ strength and low weight requirement. A breakage from this wind turbine might
