Wind Power: Its Pros and Cons
The quest to find an alternative energy resource that is in accordance
with history and latest trend in technology has paved the way for
humans to look after the environment and to preserve the natural
resources. 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
