What does a nipper do?
a nipper changes the sails on windmills
What did they use in the past for wind energy?
Windmills and ship sails.
How do the sails on the windmills turn?
by all the wind that builds up on the windmill
How do traditional windmills grind grain and bring underground water?
By capturing the power of the wind as it passes the windmill's sails. This causes the sails to turn, which rotates the sails axle and this, through gears and cogs, powers the pump or the grind stones.
Why do windmills make noise?
Because they have moving parts, such as the sails, and all moving things on land make a noise.
What were the first windmills made out of?
Made of six to twelve sails covered in reed matting or cloth material
How is air a form of energy?
Air itself is not a form of energy but wind can create energy but operating windmills, pushing sails, etc.
How does windmill blow?
A windmill does not blow.A windmill is blown by the wind.The windmills sails turn the wind into power to operate machines, pumps or electrical generators.
What is a windmill made of?
Large windmills consist of a base, often a building constructed of wood or stone, with a series of blades or sails (the flat or semi-flat pieces), and a gear-box that allow the blades to turn. School projects of small windmills can be made of a can for a base, a thin wooden stick, plastic for the sails, wires. The related link gives more information. As wind hits the blades or sails, they begin to turn (aided by the gear box). This turning energy can be harnessed to create power. As a power-producer, windmills reduce reliance on fossil fuels like coal and thereby create cleaner energy sources. The Dutch have used windmills for centuries. The USA has far fewer windmills, although more individuals have become interested in "wind power", especially over the last 30 years.
Do the blades in a windmill turn horizontally or vertically?
Windmills always turn counterclockwise, but this is an exception to the windmills found in Ireland.
How do windmills know which way to face?
There may be a small propeller on the opposite side to the main sails or there may be a vane to turn the windmill. See the examples in the links below.

How do older windmills and new windmills differ?
older windmills make more energy than newer windmills
