This article I read today on the BBC website is so inspiring. Anyone who believes that one person cannot make a difference in the world needs to read about William Kamkwamba and then think again.
The extraordinary true story of a Malawian teenager who transformed his village by building electric windmills out of junk is the subject of a new book, The Boy Who Harnessed the Wind.
Self-taught William Kamkwamba has been feted by climate change campaigners like Al Gore and business leaders the world over.
His against-all-odds achievements are all the more remarkable considering he was forced to quit school aged 14 because his family could no longer afford the $80-a-year (£50) fees.
When he returned to his parents’ small plot of farmland in the central Malawian village of Masitala, his future seemed limited…
Fascinated by science, his life changed one day when he picked up a tattered textbook and saw a picture of a windmill.
Mr Kamkwamba told the BBC News website: “I was very interested when I saw the windmill could make electricity and pump water.
“I thought: ‘That could be a defence against hunger. Maybe I should build one for myself’.”
