Wind energy
Windmills have been used for almost 1,500 years.
The first windmills were used in Persia/modern day middle east for grinding grain and drawing up water.
In ancient Egypt they used them to power boats down the nile river.
How it works?
When the wind hits rotor blades at a certain angle it propels round and round which turns a generator on that turns it into energy and puts it through power lines.
What are wind farms?
Wind farms are where there are heaps of wind turbines up on a hill producing all the wind energy that people need. Sometimes people can't get wind energy because there are limited spaces.
Countries using wind energy
There are heaps of countries using wind energy such as NZ,Aussie,Middle east and parts of Europe
The drawbacks
Some problems are that they could hit birds because they're quite high up and are white like the clouds. Some people think they're ugly and take up to much space.
