We live in a world inhabited by approximately seven billion people. If there were only one or two people in the world, doubtlessly they would not need more than one or two windmills.
The first is to describe why something HAD TO happen. The second is to describe why something DID happen. Just "the reason" is what it is, and it can be used in three different ways. You used two of them in your question
In older days, windmills were generally used to grind grain, through the wind turning the blades, which turned the grinding mechanisms. Presently, windmills can be used to convert kinetic energy into electricity, popularly seen as an alternative to fossil fuels.
The wind has been used for thousands of years. Windmills were in use by the Romans and earlier to grind corn, pump water and even cut wood.
A windmill is a machine that converts the energy of wind into rotational energy by means of vanes called sails or blades. The reason for the name "windmill" is that the devices originally were developed for milling grains for food production; the name stuck when in the course of history, windmill machinery was adapted to supply power for many industrial and agricultural needs other than milling. The majority of modern windmills take the form of wind turbines used to generate electricity, or wind pumps used to pump water, either for land drainage or to extract groundwater.
Modern windmills are becoming more widely used for the generation of electricity. Many hairstyles that were popular a generation ago are not popular today.
They capture the energy of wind so it can be transferred and used instead of creating energy.
windmills are there to help save energy and renew electricity.
Windmills use wind energy.
I am doing giant windmills in class today and I just wondered if you could answer my question for me? This is my question: 'are giant windmills used anywhere already' thankyou!!!!!! As far as I know the biggest in use now is rated at 2 megawatts
Windmills are needed usually to grind corn into wheat using wind-power. The main reason of using wind-power is because to grind corn needs a huge amount of energy and it would cost more to grind the corn into wheat than the actual price of the wheat. Nowadays windmills are not used and instead other ways are use to grind corn which are more power-efficient and therefore do not need much power and so can be powered from the grid
windmills are used now for mainly wind energy but in the old times the dutch used them to grind corn and wheat for flour
During the Middle Ages, windmills were used primarily for grinding grain and pumping water.
The first windmills were used for grinding grain and pumping water. In ancient times, windmills were primarily used to grind grain into flour, providing an efficient method for food production. Later on, windmills were also used to pump water from wells and drain marshes.
sawmills
To be used to grind grain.
The ranch didn't have to rely on springs and other natural sources to water their cattle with, they just used windmills as a source of energy to pump water to stock tanks for their cattle to drink from.
Windmills grind grain such as wheat into flour, the flour is used by a bakery to make bread.
