Read the excerpt from The Boy Who Harnessed the Wind by William Kamkwamba.

I continued to climb, slowly and assuredly, until I was facing the machine's crude frame. Its plastic arms were burned and blackened, its metal bones bolted and welded into place. I paused and studied the flecks of rust and paint, how they appeared against the fields and mountains beyond. Each piece told its own tale of discovery, of being lost and found in a time of hardship and fear. Finally together now, we were all being reborn.

It provides context that each piece of material used to build the windmill tells a tale of discovery that will show the people how important energy is.
It provides context for the idea that the people of Malawi have suffered a great deal from not having a reliable source of energy.
It provides context for the idea that the old parts that Kamkwamba used to build the machine and the people of Mawali are both experiencing new life because of the energy harnessed by the windmill.
It provides context for the idea that the windmill is a beautiful site against the mountains that will be appreciated by the people of Mawali in addition to the benefits that the energy will provide.
