Wind is free source and an alternative energy. This energy is more advantage than disadvantage. For intense, Malawian inventor, William Kamkwamba made a windmill machine to generate electric in his home. He invented of this equipment by reading a science book. Soon after reading, he made some experiment, then it changed the structure specially the windmill design and bought some material to assemble. Next, He tested this machine for tree times and then it was assembly by raw material such as plastic pipe, bamboo, propeller, cable, storage battery, etc. This machine is rotated by wind. As a result, it is able to generate electric which supplies to four lights and two radios. In age 19 years old, dropped out at the school, he spent many time in energy for better life in Malawi village. Next plan, he prepare to build hydro-power energy in Malawi.

Hello
Your text will sound much better if you apply the following adjustments to it:
Wind is [...] the alternative source of energy.
This energy [...] There are more advantages to this energy than disadvantages.
For intense [...] instance [...]
generate [...] electrical power...
He invented [...] this gadget in the aftermath of having read a science book.
he made [...] conducted a few experiments, which has led him to consider altering the structure of a conventional windmill.
fortree [...]three[...] times...
then it was assembly [...] this part of the sentence doesn't make much sense - one needs to assemble a machine prior to testing it.
electric [...] enough electricity to run four...
In age [...] At the age of...
Next plan [...] he is planning to build a hydro-power plant...
I hope this will help. Regards.
