It is a sustainable form of energy. Windmills are machines that are driven by the force of the wind upon it s propellers. The spinning of the propellers generates electricity. Windmills are sustainable energy sources. Wind is another gift that we receive free from nature.
Windmills can provide electricity to our homes.
This is called hydroelectric. There are generators that work with the help of water in the same way that windmills work. The water helps create the spinning motion of the generator which creates electricity. Kerosene and candle lamps can provide light. Before you use these lamps, it is important to learn all the safety rules from your parents or teachers.
